Species account taken from: "A Revision of the Genus Ashmeadiella (Hymen., Megachilidae) Author(s): Charles D. Michener Source: American Midland Naturalist,Vol. 22, No. 1 (Jul., 1939), pp. 1-84"


Heriades (?) cubiceps Cresson, 1879, Trans. Am. Ent. Soc., 7:205, 9 ; Schletterer, 1889, Zool. Jahrb., Abt. f. Syst., Geog. u. Biol. 4:682, 9 ; Cresson, 1916, Mem. Am. Ent. Soc., 1:116, 9 . Eriades cubiceps Dalla Torre, 1896, Cat. Hymen., 10:375, 9 ; Friese, 1911, Das Tierreich, 28:25, 9. Titusella cubiceps Cockerell, 1908, Ann. Mag. Nat. Hist., (8)2:331; Michener, 1936, Am. Mus. Nov., 875:13, 9.


This rather variable, black, sparsely punctate species has a large quadrate head and broad quadridentate mandibles in the female.


Female: Inner margins of eyes diverging below; under side of flagellum brown; clypeus impunctate except laterally, anterior matgin with median emargination; mandibles with distance from first tooth to inner apical angle (fourth tooth) equal to distance from inner apical angle to base; angle between line drawn from third to fourth mandibular tooth and inner mar in of mandibles about 1300; cheeks much wider than eyes, seen from sizes; lower part of supraclypeal area smooth; frons and vertex rather closely punc- tate; anterior ocellus near midpoint between antennal bases and posterior margin of vertex; distance between posterior ocelli equal to distance to eye, less than distance to posterior margin of vertex. Scutum a little more coarsely and less closely punctate than vertex; tegulae brownish; wings slightly dusky; mesepisternum slightly more finely punctate than scutum; hind tibial spurs about as in the preceding species except that the outer margin of the inner spur has about twelve teeth. Abdomen finely punctate, punctures of dorsum of first three tergites separated by more than their diameters; scopa dull white. Length 7 mm.


This species occurs in "Nevada" and in the higher Sierra Nevada of California.

CALIFORNIA: Gold Lake, Sierra County, July 25, 1921 (C. L. Fox, Calif. Acad. Sci.); Mt. Lassen, 6700 feet, July 21 and 22, 1937 (F. X. Williams); Monanche Meadows, Tulare County, July 26, 1935 (W. Evans); Agnew Meadows, Madera County, July 30, 1936 (G. E. -& R. M. Bohart). One of the specimens from the latter locality approaches clypeata. Specimens from twenty-five miles east of Prineville, OREGON, 3800 feet, July 13, 1936 (H. A. Scullen) and Antelope Mountain, Harney County, Oregon, August 2, 1931 (D. K. Frewing) are perhaps best placed in typical cubiceps, but approach clppeata
