MONOGRAPH OF THE NORTH AMERICAN PEOCTOTKYPID.K. 77 



Lefjs, iiiclinliiiy' Jill coxje, yellow, the anterior feniorii iiiucrli swollen; 

 wiiij;s hyiiliiu', the parastiy:mii and stijiina pit-eons. 



Abdomen lonj^er than the thorax, pointed at apex, smooth and pol- 

 ished, the venter sometimes piceons towards base. 



The male is the smaller and agrees i)erfectly with the female, the only 

 noticeable difference being in the shape of the abdomen, which is ob- 

 long oval, slightly dejiressed, not pointed at apex, and scarcely as long 

 as the thorax. The Hagellum is more distinctly brown, the joints very 

 slightly longer than ia the female. 



Types in National Museum. 



Bred by II. (I. Hubbard at Crescent City, Fla., from Vlatynota rog- 

 trana, and by myself at Jacksonville, Fla., from the (uange case worm, 

 PlatasceticuH (Uorerli Packard. 



NoTK. — The following fj;eiius has uot been recojjuized : 



Notwithst.iiulin^f the fact that the auteuiiie are deserihetl as 2ti-j(>into(l, the };enus 

 evidently beh)n<j;8 in this j^roup. I merely ropy Stefaiiu's description witli tht^ hope 

 that it may some day aid in its identification. Were it not for tln^ 2t)-jointed an- 

 tenme I should say the jjeniis was identical with eitlu^r I'rixtocera or Svleroderma'.- 

 It is possible, though, the autennai will be found to be only lli-jointe<'i, each Joint 

 bein^ constricted and having the apjiearance of forming two joints. Such mistakes 

 have frequently occurred in systematic entomology.
