NO. 1206. ICHNEUMON FLIES— ASHMEAD. 115 



By many authorities it was formerly includcKl in the famil}^ Evan/idiE, 

 althouo-h it has not a sino-le character in common with any now placed 

 in that family. The abdomen is attached somewhat above the inser- 

 tion of the hind coxa>, but not on the dorsum of the metathorax, has 

 a distinct ventral fold, and so far as the flexibility of the segments is 

 concerned, as well as in its thoracic characters, comes nearest to the 

 Aphidiidce. 



In other characters it resembles certain Ichneumonids belonging to 

 the subfamily Ojihlonhue. The clypeus is prominent, subrostriform, 

 with two large, deep spiracles; the antennas are 13-jointed, the scape 

 and pedicel being subglobose, and equal or nearly in size; the front 

 wings have a large, lanceolate stigma, two cubital cells, and a long, 

 narrow, acutely pointed marginal cell; the hind coxge are very long 

 and almost cylindrical, while the abdomen is longly petiolated. 



The tribe is leased upon the genus Paxylomma De Brebisson, changed 

 by Forster to Pachylomma. I do not believe anyone has the right to 

 change a generic name, w^hether correctly or incorrectly formed, and I 

 here restore the original spelling and call the group I'axylonimince. 



Three genera have been recognized, as follows: 



TABLE OF GENERA. 



First joint of hind tarsi scarcely one-third longer than the four following joints 



united, or of an equal length 2 



First joint of hind tarsi twice as long as the four following joints united 3 



2. Second cubital cell longly petiolated, the radius divided into three abscissae. 



(903) Paxylomma De Brebisson=Pac/i2/Zoni?«a Forster. 



Second cubital cell sessile, or at the most subsessile, the radius divided into two 



abscissae (904) EupacJxylomma Ashniead. 



3. Second cubital cell sessile, the radius divided into two abscisste. 



(905) Eiirypterna Forster.

In having a distinctly petiolated abdomen this subfamily agrees with 

 both the Paxyloinmlniti and the Meteorinm. From the former it is 

 separated by the venation of the front wings, the large and broad 

 stigma, and usually by the short marginal cell. The marginal cell is 

 sometimes long, but is broader and entirely diflierent from that in the 

 Paxylomininw; the coxffi are normal, never long, cylindrical, while the 

 abdomen is attached normally. From the ^fetcorincje it is distinguished 

 by having at the most but two cubital cells.
