DISTRIBUTION—Colorado and North Dakota, east to Illinois, Wisconsin and Michigan, June to August.

FLOWER RECORDS—Robertson (1922 & 1929) records this on three species of Verbena, V. hastata, V. stricta and V. urticaefolia.

Extracted from: Shinn, A.F. 1967. A Revision of the Genus Calliopsis and the biology and Ecology of C. andreniformis (Hymenoptera: Andrenidae). U. Kans. Sci. Bull. 46: 753-936.

Timberlake considered this one of the species of Calliopsis s.s. and I concur, but it has characters which link it as an intermediate between Calliopsis s.s. and Perissander.

It is closest to C. peninsularis, which will doubtless be proven a Calliopsis s.s. when the male becomes known, but is readily distinguished by the mesotibial spur being bare and 0.75 times or more the length of the middle basitarsus (less than 0.60 in peninsularis).

TYPE MATERIAL. Holotype male from Picacho Pass ( 5 mi. S.E. of Picacho) [summit is at 1800 ft. altitude], Pinal Co., Arizona, Aug. 7, 1940 (P.H. Timberlake), on Euphorbia, is in the Timberlake collection at the University of California, Riverside, California. The above description of the male is based primarily on a topotypical specimen collected by C. D. Michener in company with Prof. Timberlake at the time of collection of the holotype.

D1sTRIBUTION, Known only from southern Arizona but to be expected from southwestern New Mexico and northern Sonora, southeastern California, and Baja California.

Specimens have been studied from the following localities: ARIZONA: Apache (5 mi. S.E.; 14 mi. S.W.), Cochise Co., Aug, 7-11, on Euphorbia, (13 mi. S.W.), Aug. 19-26, on Euphorbia, (5 mi. S.W.), Aug. 17, on Bacchar-is glutinosa; Douglas, Aug. 26 (3 mi. N.; 17 miles E.), Cochise Co., Aug. 8, on Euphorbia; Picacho Pass (5 mi. S.E, of Picacho), Pinal Co., Aug. 7, on Euphor• bia; Portal (2 mi. N.E.), Cochise Co., Sept. 14; Roll, Yuma Co., July 11-Aug. 11, Oct. 20, on Euphorbia and Alfalfa; Tempe, Aug. 1.

GEOGRAPHIC VARIATION. Specimens from Roll in southwestern Arizona differ from those in middle southern and southeastern Arizona by having denser, shorter, more plumose hair on the face, thorax, and abdominal hairbands. Females from Apache and Douglas have greatly reduced areas of cream color on the head. Other minor differences in certain head and thoracic dimensions occur, but without males I must consider these within the range of variation of the species

D1scuss10N. Most of the flower records are from Euphorbia, a biological datum bolstering the morphological data which indicate a relationship with Perissander.

B10NoM1cs AND FLOWER RECORDS. Nothing is known of the bionomics of squamifera, but it has been taken on each one of the favorite plant families for the genus: Compositae, Baccharis glutinosa; Euphorbiaceae, Euphorbia; and Leguminosae, Alfalfa, Medicago saliva.
