SOME BEES FROM THE HIMALAYA MOUNTAINS. 241 



head long and black, strongly mixed with pale grey on the face, of 

 thorax also long and black, with a broad grey band (mixed with 

 black) extending from tubercles across anterior part of mesothorax, 

 and some long white or pale grey hair at sides of metathorax ; middle 

 of disc of mesothorax, anterior part of scutellum, and postscutellum 

 smooth and shining ; metathorax dullish ; pleura closely punctured ; 

 tegulfe small, piceous; wings a little dusky, especially along apical 

 margin ; nervures brown, stigma ferruginous ; b. n. meeting t. m., 

 or failing to reach it by a short distance ; first r. n. joining second 

 s. m. at end of first third ; third s. m. narrowed more than half above, 

 receiving second r. n. about as far from apex as first r. n. is from apex 

 of second s. m. ; stigma small ; marginal cell pointed ; legs black, 

 with black hair, that on inner side of tarsi variably reddish, and 

 sometimes orange on inner side of middle tibiae ; claw-joints ferru- 

 ginous ; spurs ferruginous ; abdomen finely punctured ; first segment 

 with mostly white hair, but black posteriorly, second with black, the 

 others with appressed bright fox-red hair, but that on sides of fifth 

 white ; venter with black hair, white on sides of apical palpi ; pygidial 

 plate small. 



This might be taken for an Andrena, but it has the Melitta 

 venation, no facial foveae, and straight hairs, but no floccus, on 

 hind trochanters. 



Hab. Gyangtse, 13,000 ft. June, 1904 (H. J. Walton ; Thibet 

 Expedition). British Museum. Two females. 



Easily known from all other species by its coloration. The 

 genus is now first recorded from the Himalayas, but years ago 

 Colonel Bingham showed me an undescribed Melitta from this 

 region. 



Colletes sanctus, sp. nov. 



$ . Length about 12 mm., expanse about 22 ; black, the head 

 and thorax above covered with bright fox-red hair ; at sides and 

 beneath, and on legs, it is pale yellowish, but the bright red extends 

 down beyond and over the tubercles. Abdomen shining black, finely 

 punctured, with scanty pale hair at base, but beyond that with black 

 hair, which is very inconspicuous ; no indication of pale bands. 

 Mandibles reddish at apex ; antennae entirely black, the third joint 

 not quite so long as the next two together ; front densely punctured ; 

 facial foveae much as in C. succinctiis, but narrower, and well-defined 

 on the inner side ; clypeus prominent, densely and coarsely striato- 

 punctate ; malar space large, but broader than long ; mesothorax and 

 scutellum with dense large punctures, except discally, where they 

 become smooth and sparsely punctured (scutellum) or impunctate 

 (mesothorax) ; pleura with close strong punctures ; area of metathorax 

 with coarse ridges bounded as usual by a transverse keel, the enclosed 

 spaces small, irregular, longer than broad ; sides of metathorax rough ; 

 tegulae piceous ; wings dusky hyaline, nervures and stigma dark red- 

 dish ; second s. m. very broad, receiving first r. n. a short distance 

 beyond middle ; legs normal, hind spur ciliate ; first abdominal seg- 

 ment shining, with small scattered punctures ; the others with 

 minute, much closer punctures.
