N'HNKUMONIDJK. 



is widely distributed, and in Cuba, according to Cresson. it 

 devours the eggs of Periplaneta Americana. 



The genus Autocodes of Cresson, "forms a very close con- 

 necting-link between the minute Ichneumons and the Evania'." 

 .1. nigriventris Cresson (Fig. 124, a; &, metathorax; <>, inser- 

 tion of the abdomen) lives in Cuba. 



Faeiins is quite a different genus, as the abdomen is very long 

 and slender. Fmnus jaculator Linn, is known in Europe to 

 frequent the nests 

 of Crabronidce, 

 ovipositing in the 

 larvae.

distinguishing it. The male is extreme!}- rare ; its abdomen 

 is short and clavate. It strikingly resembles Trypoxylon, 

 though the abdomen is considerably larger. Pelwhnis j>/>/- 

 <-c>-tor Drury (Fig. 125, $ and ?) is widely distributed 

 throughout this country. 



The genuine Irfn>t'Hioiti<I<i'. have long, straight, nniltiartini- 

 late antenna. 1 . The first subcostal (cubital) cell of the fore- 

 wings is united with the median 

 cell lying next to it, while the 

 second is very small or wholly 

 wanting. There are two recurrent 

 veins. Mr. Cresson has described 

 the genus Eiphosoma (Fig. 12<i ). 

 Fig. i2ii. which he states may be known by 



the long, slender, compressed abdomen, and the long posterior 

 legs, with their femora toothed beneath the tips. E. <I.H:IH- 

 /(itnm Cresson, a Cuban species, is, according to Poey, "para- 

 sitic upon a larva of Pyralis." (Cresson.) 



In Ophion the antennae are as long as the body, the abdo- 

 men is compressed, and the species are honey-yellow in color. 

 O. macrurum Linn. (Fig. 127) attacks the American Silk- 

 worm, Telea Polyphemus. Atiomalon is a larger insect and 

 usually black. A. iwspa.rum is, in Europe, parasitic on Vespa.
