NEW AND LITTLE KNOWN BEES. 



BY T. D. A. COCKERELL. 



Sphecodes cliioiiospilns n. sp.— c?. Length about 7\ mm.; 

 head and thorax black ; abdomen red, the apical segments dusky, the 

 hind margins of the segments (the second and third very broadly) 

 reddish-golden ; legs reddish-black, the knees, hind tibiae at base and 

 apex, and all the tarsi, ferruginous; spurs pale testaceous; tegulae 

 creamy-white, testaceous at base ; wings hyaline, dilutely infuscated 

 apically, stigma and nervures brown-ferruginous. Head transversely 

 oval ; eyes converging below ; face and front very densely covered 

 with snow-white pubescence ; mandibles dark ferruginous ; cheeks and 

 upper part of head with white hair ; antennae dark reddish, long, very 

 strongly moniliform ; scape short ; second and third joints very short, 

 twice as broad as long ; fourth nearly twice as long as second and third 

 together ; mesothorax and scutellum shining, with very large scattered 

 punctures ; metathorax above rounded, shining, very coarsely cancel- 

 late ; upper border of prothorax, mesothorax in front, scutello-meso- 

 thoracic suture, postscutellum and pleura (the last irregularly) covered 

 with white hair ; abdomen shining, with strong widely separated punc- 

 tures, base of second segment depressed ; last ventral segment with a 

 shallow median longitudinal depression. 



Variety sang'uinatus n. var. — cf . Legs entirely bright ferrugin- 

 ous red, with white hair on tibiae and tarsi ; metathorax above not 

 clearly cancellate, but irregularly roughened, the rugae more or less 

 evidently longitudinal. This looks at first like a distinct species, but 

 every essential detail is as in chionospiliis, and it can hardly be more 

 than a variety. 



9 . Length about 9 to 10 mm., differing from the male in the usual 

 sexual characters, but otherwise similar ; mandibles with an inner 

 tooth, far from the apex ; fiagellum thick, suffused with dark reddish ; 

 legs dark with the tibiae and tarsi more or less reddish, or (var. san- 

 guinatus) entirely red ; mesothorax and scutellum black, or (var. san- 

 gidnatus) dark reddish ; hind tibiae densely covered with white hair on 

 outer side; hind spur microscopically serrulate ; tongue sharply pointed, 

 about 400 microns long ; last five joints of maxillary palpi in microns 

 (2.) 128, (3.) 128, (4.) 96, (5.) 112 (6.) 64. 



/r«^z7a/.— Karachi, N. W. India, May and June, 1909, {E. 

 Comber). British Museum. In a number of characters this 

 resembles 5. indiais Bingham, but that has the male entirely 

 black, and the hair on the tarsi ferruginous-brown instead of
