typus armatus) attacks the fully grown larva of a Phryganea 

 ( Aspatherium), which inhabits a smooth cylindrical case, 

 wliicli the Ichneumon converts into a pupa case by spinning 

 a long broad baud of silk around the anterior opening. (Ger- 

 staecker.) 



In Nearonia and Phruganca the maxillary palpi difier in the 

 two sexes, and there are two spurs on each of the fore legs, 

 and four on the middle and hind legs. The maxil- 

 lary palpi in the males are four-jointed, in the females 

 iive-jointed, and there are three ocelli. Neuronia 

 differs from I'hryganea in having its 

 antennae a little shorter than the wings, 

 whereas in the latter the3' are longer, 

 and the fore wings an^ hairy. Neu- 

 roma semifasciata Say is I'ulvous, with 

 '"" ' '■ the fore wings transversely flecked with 

 brownish-black, a small basal spot, and an abrupt, 

 median streak at the hinder margin of the wing, while 

 the disk has two yellowish spots, and there is a short 

 fuscous subapical Ijand on the hind wings. Fig. GOG rig. gw.

 In the group LlmnopliiUdes the maxillary palpi of the males 

 are three, those of the fe- 

 males five-jointed ; ocelli 

 three ; anterior wings rather 

 narrow, the apex obliquely 

 truncated or rounded. In 

 Limnophilas the tibial spurs of the three paii-s 

 of legs are arranged thus, 1, 3, 4 (i.e., one 

 spur on the front pair of tibiae ; 

 three on the middle, and four 

 on the hinder pair), and the 

 apex of the anterior wings is 

 truncated. L. perjvisHlus
