K0.2216. NEW REARED ICHNEUMON-FLIES— CnSIIMAN. 463 



The male paratypes display as much and similar variation. The 

 clypeus, scape, lower orbits, and scutellum vary from white to piceuos 

 or black, but the general body color does not determine the color of 

 these parts. Paratype i, for instance, is otherwise very similar to the 

 allotype, but all of these parts are especially pale, the white embracing 

 in addition the cheeks and a spot above the clypeus. Paratype Ic, on 

 the other hand, which is not otherwise darker than the type, has the 

 entire face black, the scape and scutellum piceous, the clypeus 

 piceous with a minute yellowish spot, and the mandibles stramineous . 

 In none of the specimens is the thorax entirely black nor entirely red, 

 the allotype displaying nearly the maximum of black and paratype I, 

 in which the mesoscutum is dark fuscous, the maximum of red. In the 

 latter specimen the white of the hind tarsi embraces also the fourth 

 joint and on the left leg the black of the first joint is only faintly 

 indicated. 



This species has also been reared from the same host at Put-in-Bay, 

 Ohio, under Quaintance No. 14433, by Mr. E. R. Selkregg, of the 

 Bureau of Entomology. 



Genus CAENOCRYPTUS Thomson. 



No specimen of either of the species originally included in this 

 genus by Thomson is available for study, but the species described 

 below runs here in the tables (of both Ashmead and Thomson) to the 

 tribe Cryptini. Both of these tables are difficult to use with cer- 

 tainty because of the variability of the characters and the large num- 

 bers of comparative words employed. The present species possesses 

 most of the characters which Thomson says "usually," "not rarely," 

 or "frequently" exist as well as the very few characters which he 

 states positively.
