British Braconidce. 141 



The smallest known British species, and easily dis- 

 tinguished by the colour of the abdomen. I have not 

 seen the male, but most likely it is one of those furnished 

 with an anal perforation. The two specimens at hand 

 are very old, and in no condition to be described. 



Discovered by Walker, and briefly noticed by Curtis, 

 I. c. One of the original specimens is in my collection, 

 and more, as I learn from Prof. Westwood, in the Oxford 

 Museum. 



iii. AscoGASTEE, Wesm. 

 Wesm., Nouv. Mem. Ac. Brux., 1835, p. 226. 



Eyes glabrous. First cubital areolet distinct from the prse- 

 discoidal. Otherwise identical with the preceding genus. 



A convenient artificial section of Cheloniis, improperly 

 called a genus, co-extensive with Section III. of Nees. 

 Wesmael originally included in it Chelonus dentatus, 

 Panz., but for this he afterwards formed, with better 

 reason, the genus Phanerotoma. The species have been 

 revised by Reinhard in the Berl. ent. Zeit., 1867, where 

 he describes seventeen, of which nine have been detected 

 in Britain. These appear to have been all known to 

 Haliday and Curtis ; the latter is the only English writer 

 who has described any, but the descriptions are mostly 

 insufficient for their determination. We have added a 

 single new species.
