672 Descriptions and Records of Bees. 



Museum; it is in poor condition. It looks like a Nomiine 

 with the second t.-c. wanting, Init it is very different from 

 Steganomus nodicornis by the pointed marginal cell and the 

 A/tdrena-Yihe basal nervure, falling a little short of t.-ni., 

 and not bent at its lower end. (Bingham's figure of the 

 basal nervure of Steganomus nodicornis is misleading, as 

 shown by a specimen in my possession from F. Smith's 

 collection.) The third t.-c. has a very strong double curve 

 and does not resemble this nervure in Melitta. There is no 

 curled floccus on hind trochanter^ and the sides of face are 

 shining, wholly without fovese. The flagellum is short like 

 that of Nomia, red beneath. The area of metathorax is 

 finely granular ; the sides of the apical truncation are 

 rounded, and there is a deep apical pit ; the metathorax is 

 wholly different from that of Xomia arizoncnsis, flying in 

 the same general region. The hind tarsi have long coarse 

 simple hairs. Clypeus smooth and shining, with scattered 

 punctures, large and very small ; mandibles bidentate ; 

 pubescence of thorax above matted, cannot be described ; 

 hind margins of abdominal segments reddened ; apical i)late 

 of abdomen round at apex, its surface concave, no sign of 

 any keel. The palpi have never been examined. In the 

 \cnation, the character of the metathorax, the short flagel- 

 lum, &c., Panurgomia nearly agrees with Dasypoda, but the 

 latter has the apical plate of abdomen emarginate. On the 

 whole, I think Panurgomia will prove to be an American 

 representative of Dasypoda. 



DoUchochile melittoides, Yiereck. 



I examined the female type in the U.S. National Museum. 

 Sides of face shining, without foveae ; mandibles extx'cmeiy 

 long, with a pair of little notches near the middle, the 

 interval between them forming a small tooth ; venation 

 as in Melitta, with the characteristic third t.-c and jiointed 

 marginal cell; area of metathorax granular, not detined ; 

 apical plate of abdomen pointed, strongly keeled. Melitta 

 uintricana has the keeled apical plate, but different meta- 

 thorax and mandibles. In the Asiatic M. altissima the 

 ajtical plate is not in the least keeled. DoUchochile is a 

 valid genus, close to Melitta. 



Melitta [Brachycephalapis] californica, Aiereck. 



I examined the type female in U.S. National ]Musenni. 

 Ko facial fovea" ; black hairs at extreme sides of face ;
