672 Descriptions and Records of Bees. 



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

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

 Stegayiomiis nodicornis by the pointed marginal cell and the 

 Andrena-Wke basal nervure, falling a little short of t.-m., 

 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. Smithy'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 foveae. 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 Nomia arizonensis, 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 plate 

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

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

 \enation, 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 

 wliole, I think Panurgomia will prove to be an American 

 representative of Dasypoda. 



Dolichochile melittoides, Viereck. 



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

 Sides of face shining, without fovcce ; mandibles extremely 

 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 pointed 

 marginal cell; area of metathorax granular, not defined; 

 apical plate of abdomen pointed, strongly keeled. Melitta 

 americana has the keeled apical plate, but diff'erent meta- 

 tliorax and. mandibles. In the Asiatic M. altissima the 

 ajiical plate is not in the least keeled. Dolichochile is a 

 valid genus, close to Melitta. 



Melitta [Brachycephalapis) californica, Viereck. 



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

 No facial fovcse ; black hairs at extreme sides of face ;
