NO. 2031. NEW VARIETIES OF ICHNEUMON-FLIES— VIERECK. 371 



brownish, scutel with a U-shaped border of radiating hairs, hind coxse 

 black, brownish, and yellowish, hmd femora and hind tibise reddish 

 brown, the latter brownish at base and apex with brownish spurs, 

 hind tarsi yellowish excepting their appendages which are blackish; 

 propodeum virtually crowded out by the transverse oblong areola, 

 petiolarea excavated and occupying the greater portion of the apical 

 five-sixths of the propodeum, propodeal protuberances laminate and 

 directed outward, backward, and downward; abdomen reddish and 

 yellowish and more or less covered with blackish stains, first, dorsal 

 segment mostly stramineous, its spiracles nearer to the apex than tc 

 each other. 



CRYPTOPTERIGIMORPHA, new genus. 



Type. — Cryptopterigimorplia tubuUfera, new species. 



Related to Cryptanuridimorpha Viereck with the original descrip- 

 tion of which it agrees except in the recurrent vein, which is not 

 interstitial. 



In a more rational classification of the Ichneumonidae than is now 

 popular these two genera will represent at least a new tribe because 

 of the unusual conformation of the oral cavity. 



CRYPTOPTERIGIMORPHA TUBULIFERA, new species. 



Type-locality. — Piches and Perene Vs, Peru Soc. Geog. de Lima; 

 altitude 2,000-3,000 feet. 



Type.— C&t. No. 16224, U.S.N.M. 



Female.— hength. 14 mm.; brownish stramineous and sliining; head 

 and antennae mostly black, palpi stramineous, mandibles yellow with 

 blackish tips, clypeus partly brown, part of the third, all of the fourth 

 to the tenth joints, inclusive, and most of the eleventh joint of the 

 flagel whitish, the fifteenth and many of the following joints of the 

 flagel facetted above, the malar space shagreened or granular while 

 the rest of the head is rather polished and punctured; pro thorax, 

 mesonotum and the anterior edge of the mesopleurse mostly black or 

 blackish, fore and mid legs paler than the. body and the hind legs, 

 their tibise rather sinuate, their second tarsal joint at the tip and the 

 following tarsal joints entirely blackish, hind tarsi whitish, their claws 

 dark brown, wings tinged with brown, their veins dark; propodeum 

 exceedingly as in Cryptopteryx Ashmead, the spines rather truncate 

 at the tip; sheaths of the ovipositor nearly half as long as the 

 abdomen. 



DIAGLYPTIDEA, new genus. 



Type. — Diaglyptidea roepJcei, new species. 



Agrees with the original description of Diaglypta Foerster. Diag- 

 lypta (Foerster) Ashmead does not agree with the original description 

 of Diaglypta Foerster, and is related to Allocota (Foerster) Ashmead.
