NEW AND LITTLE-KNOWN BEES. 



BY T. D. A. COCKERELL, N. M. AGR. EXP. STA. 



Chelynia rubifloris, n. sp. — $ . Eight mm. long, black, with sparse 

 grayish and white pubescence. Head almost as large as thorax, quad- 

 rate, produced behind the eyes, cheeks very broad ; cheeks, vertex and 

 face very strongly and closely punctured ; region of antennae with some 

 dull white hair ; ocelli in a triangle : antennae rather short, black, last 

 joint compressed, funicle longer than first flagellar joint, first flagellar joint 

 conspicuously longer than second or third ; clypeus broad and low, punc- 

 tured all over, its anterior margin bearing a small tooth at each side, 

 and in the middle a long, narrow projection, like the thoracic spine of 

 some species of Oxybehis. Mandibles black, stout, obscurely bidentate 

 at the obliquely truncate ends. Labrum greatly produced, hollowed 

 beneath, sides parallel, end truncate. Tongue very long, linear ; max- 

 illae greatly elongated ; penultimate joint of labial palpi broadened at 

 apex, shorter than the last ; basal joint not quite half, but more than one- 

 third, length of second ; maxillary palpi small, three-jointed, the joints 

 subequal. Thorax rather small, strongly and closely punctured ; base of 

 metathorax coarsely wrinkled, bounded by an obtuse rim. Tegulae black, 

 punctured. Wings smoky, nervures and stigma black, stigma well-formed 

 but small ; marginal cell long, with an obtuse apex away from costa ; two 

 submarginal cells, second receiving first recurrent nervure at a distance 

 from base nearly equal to length of first transverso-cubital nervure, and 

 second recurrent very near the apex. Legs black, with thin whitish pub- 

 escence. Abdomen punctured, with obscure silvery pile towards the 

 end ; hind margins of segments with white hair-bands, very broadly in- 

 terrupted on the first three segments, on the first reduced to lateral 

 patches. Venter with a fairly abundant white scopa. 



Hab. — Seattle, Washington State. (T. Kincaid.) Two at flowers of 

 Rubus ur sinus, May 14. 



In describing this extraordinary bee I have given the generic as well 

 as specific characters. Provancher placed his genus Chelynia among the 

 Panurgine Andrenid?e, but the insect now described is an Apid allied 

 clbsely to Heriades, and especially to Ashmeadiella. This circumstance, 

 and the fact that Provancher's C. labiata does not exhibit the remarkable 

 clypeal process, might seem to throw doubt on the generic identification ; 

 but the large head, the extraordinary labrum, etc., are all as Provancher 

 describes, and it seems very improbable that he could have had another 

 genus before him.
