Perdita ignota basalis, n. subsp.


In 1956 I recorded a few specimens of ignota from the Rio Grande valley under the typical subspecies. I now have a good series of ignota from Matamoros, and a distinct subspecies is indicated by the constant presence of two white dots or spots on the basal tergite of the abdomen

Female.—Head and thorax dark green. Base of mandibles, clypeus, subtriangular lateral marks, collar of pronotum, two rather large spots on hind margin of disk, and tubercles white. Labrum testaceous, the apical half of mandibles rufotestaceous and red. Abdomen black, with two white dots or spots, sometimes confluent, at summit of basal declivity of tergite 1, and an interrupted white band at base of tergites 2 to 4. Pygidium ferruginous. Antennae and legs dark, the scape white beneath, the anterior side of front tibiae and the tarsi whitish, the middle and hind basitarsi usually tinged with pale brown. Wings whitish hyaline, witfh a just perceptible dusky tinge, the nervures pale testaceous, the subcosta and lower margin of stigma pale brown

Agreeing with ignota in structural characters except that the pygidial plate appears to be a little larger and broader at apex. Frons and mesonotum tessellate and dullish, but less so than in isopappi and crawfordi. Pubescence about as in crawfordi. Length, 4-5 mm.; anterior wing, 2.6-3 mm


Male.—Similar to female, but abdomen without white markings. Basal half of mandibles, labrum, clypeus, and lateral marks yellowish white; the lateral marks well developed, subtri angular, rounded on inner side, and generally broader than high. Marks on pronotum and tubercles small or absent. Abdomen fuscous, the apical segment and venter testaceous brown, and the apical depression of tergites 2 to 4 sometimes similarly colored. Antennae ferruginous, the flagellum more brownish above, the scape yellowish white. Legs fuscous, with the knees, an terior side of front and middle tibiae, and the tarsi pale yellowish.


Head as broad as long, the cheeks not broadened but with a small blunt tubercle anteriorly. Mandibles attenuate on apical third and reaching a little beyond the far margin of proboscidial fossa. Head and thorax shining, the frons and mesonotum rather faintly tessellate and with minute sparse punctures. Length, about 3.5-4 mm.; anterior wing, 2.5-2.8 mm.

Perdita ignota jaliscana, n. subsp.


This is like isopappi in the face markings, but the sculpture agrees with typical ignota.


Female.—Head and thorax dark green. Clypeus, except anterior margin and the lateral extensions, and small lateral marks adjacent to the clypeus white. Collar of pronotum and narrow mark on each side of hind margin of disk white, the tubercles usually dark. Abdomen blackish, with a broadly interrupted white or pale yellowish band on tergites 2 and 3. Antennae dark, the flagellum yellowish brown beneath. Legs blackish, the anterior side of front tibiae with a yellowish streak, the tarsi pale testaceous or yellowish white. Wings milky hyaline, the nervures pallid, the subcosta pale brown, the stigma yellowish


Structurally like ignota, the pygidial plate rather narrowly rounded at apex. Frons and mesonotum shining, the tessellation rather weak. Punctures and the erect, somewhat mosslike hair of mesoscutum moderately close. Length, 4.5-5 mm.; anterior wing, 3-3.3 mm


Male.—Dark blue-green, with the basal half of mandibles, the clypeus, and small lateral marks adjacent to the clypeus white, or the lateral marks sometimes absent. Mandibles shading through testaceous to red at apex. Thorax and abdomen without markings, the apical segment of abdomen pale testaceous, the venter brown. Antennae ferruginous beneath, the flagellum darker above, and the scape yellowish beneath. Legs dark, the knees, front tibiae except behind, and the tarsi yellowish white. Wings as in female.


Head usually moderately enlarged, the cheeks as broad as the eye and armed with a rather large laminate process anteriorly. Mandibles reaching shortly beyond the far margins of the proboscidial fossa. Flanks of the pronotum deeply grooved, but disk of pronotum not abbreviated. Vertex faintly tessellate, the frons and mesonotum polished, with punctures of mesoscutum minute and sparse. Length, 3.5-4.25 mm.; anterior wing, 3-3.2 mm
