SpJiecodes eiistictus, Cookerell. 



The known range is greatly extended by a female from 

 Pullman, Washington State,' Sept. 13, "l908 {W. M. 

 Mann) . 



Sphecodes I'oJnven, Cockerell, yar. a. 



$ . — Abdomen chestnut-red, with the apex suffusedly 

 blackish ; wings greyish. 



Hab. Santa Fe, ' Kew Mexico, Aug. 1, 1902, 2 ? 

 (Cockere/l). 



S. rohiveri is known only by a single female, which agrees 

 in structure with the Santa Fe insect, but not altogether in 

 colour. It is possible that a valid subspecies is indicated, 

 but more material is required. The simple mandibles 

 separate tbis from S. eustictus, &c. 



Andrena vestali, sp. n. 



(^ . — Length about 11 mm., anterior wing 8. 



Rather robust for a male ; black, with abundant lively 

 fox-red hair ; clypeus cream-colour, with two cuneiform 

 marks and the narrow lower margin black ; head broad ; 

 cheeks rounded^ simple ; process of labrum very broadly 

 truncate, not emarginate; malar space extremely short; 

 sides of face shining, front dull and granular ; antennae 

 black, third joint a little longer than the next two combined ; 

 sides of vertex depressed ; niesothorax closely and distinctly 

 punctured, the spaces between the punctures moderately 

 shining ; area of metathorax dull and granular, not margined ; 

 tegulse piceous. Apical part of wings suffusedly dusky ; 

 nervures and stigma dark reddish, stigma rather small ; 

 second s.m. receiving first r. n. a little beyond beginning of 

 last third ; the long third s.m. greatly narrowed above, so 

 that on marginal it is less, or no greater, than lower side of 

 second s.m. beyond insertion of r. n. Abdomen shining, 

 rather roughened with fine piliferous punctures, the second 

 segment depressed hardly a third ; the red hair of abdomen 

 forms a thin covering all over, and is dense at apex, but 

 does not form bands ; the ventral segments have evident 

 marginal hair-bands. The joints of the labial palpi measure 

 as follows in fi: (1) 288, (2) 17G, (3) 160, (4) 208. 



Hab. Five miles east of Boulder, Colorado, on Mesa, at 

 flowers of Viola nuttalli, May 3, 1912 {A. G. Vestal). 



Superficially resembles A. leptanihi, from which it is quite 

 distinct. In Bruner^s table of Andrena it runs to A. kin- 

 cuidii, which has a much broader head, broader clypeus, and
