Abdomen sessile, fusiform, the tbird seg:ment sliolitly tlie longest; in 

 9 pointed at apex, in S truncate, with 2 i)rongs. 



Legs moderately stout, pilose, the tibial spurs 1, 1, 1, well developed, 

 the tarsi not, or but slightly, longer than the tibiiip, the basal joint of 

 hind tarsi about oh times as long as the second, with stitf bristles 

 beneath. 



The three impressed lines on mesonotum, the spined postscutelluni, 

 and the venation separate the genus at once from all others, although 

 otherwise it resembles Baryconiis and Macrotelcia. 



Besides the species described here from ]S^orth America, I have 

 another species in my collection from South America. Nothing is 

 known of the habits of the genus.

Habitat. — Jacksonville, Fla., and Arlington, Ya. 



Types in Coll. Ashmead. 



The types of this species and genus were collected by myself in 

 Florida, but I have a $ taken in Virginia, and Mr. Herbert Smith has 

 taken another species in South America, so that the genus is widely 

 distributed. 



CREMASTOB^US Ashm., gen. nov.

 oft" towards occiput, the latter a little emarginated ; ocelli 3, triangularly 

 arranged, the lateral touching the eye ; eyes very large, round, hairy.
