Laemobothrium sp. 



Two specimens from "grasshopper hawk" (Charuplaya, 

 Bolivia). Although this species differs obviously from any 

 Laemobothrium yet described in satisfactory manner, we 

 shall not add a new species to this genus until the existing 

 species determinations have been thoroughly revised. The 

 genus is at present in a simply impossible condition. 



Physostomum doratophorum Carriker. 



Several specimens from three (three species?) "humming- 

 birds." (Choro. Bolivia.) 



A New Genus of Nomadine Bees. 



BY S. A. ROHWER, Washington, D. C. 



Some time ago Professor T. D. A. Cockerell requested in- 

 formation as to the generic position of Pasites pilipes Cresson. 

 Late in October, Mr. J. C. Crawford, Jr., examined Cresson's 

 type, which is in Philadelphia, making sure that the speci- 

 mens in the U. S. National Museum were the same species as 

 the type. On examination it was found that this species rep- 

 resents a new generic, or subgeneric, group in the family 

 Nomadidae, differing from Pasites and the other genera in a 

 number of points. The accompanying figures were made from 

 camera lucida sketches : 



Nomadosoma new genus. 



Type of the genus: Pasites pilipes Cresson (Cuba). 



Rather small bees of Nomadine habitus ; smooth and shin- 

 ing; mandibles simple; maxillary palpi as in figure i; labial 

 palpi four-jointed, the two basal joints as in figure 2, the two 

 apical joints were accidentally broken ; third antennal joint but 

 little shorter than joints four and five; frontal carina almost 

 wanting; scutellum flat, level with the mesonotum, somewhat 

 depressed in the posterior middle ; anterior coxae with short 

 tubercles, which are more distinct in the male, legs of the fe- 

 male more hairy than in male, and more hairy than in most
