width in its widest part ; it has a narrow subdorsal whitish 

 line and a lateral one of the same color. When ready to 

 transform it webs together several leaves and passes the pupa 

 state in the nest thus made. The adult (Fig. 351) is a blackish- 

 brown moth, with an irregular grayish 

 shade on the outer half of the fore 

 wings, and with very broad hind wings. 

 The palpi, which are not well shown in 

 Fig. -&i..—Hyfiena scabra. the figure, are long, wide, and flat- 

 tened ; they project horizontally like a snout. 



The Hop-vine Hypena, Hypena humuli (H. hu'-mu-li), 

 is closely allied to the preceding and has often been con- 

 founded with it. The larva feeds on the leaves of hop, and 

 is sometimes a serious pest. 



One of the most abundant of our Deltoids is Pseu- 

 daglossa lubricalis (Pseu-da-glos'sa lu- 

 bri-ca'lis.) In this species (Fig. 352) 

 the fore wings are chocolate-brown, 

 crossed with yellowish lines ; the hind 

 wings are much lighter. The palpi 

 are long; but they are curved over 

 the head, so that they appear short when seen from above, 

 as represented in the figure. The larva feeds on grass. 



Next to the Deltoids there is placed a group of moths 

 which may be called the Similar-winged Owlets, from the 

 fact that both pairs of wings are similarly marked by trans- 

 verse lines. The group includes the largest of our Noctuids. 



The two following species 

 will serve to illustrate this 

 group. 



The Lunate Similar- 

 wing, Homoptera lunata 

 (Ho-mop'-te-ra lu-na'ta.) — 

 This is a brownish moth 



Fzg. Z s-i--Ho,noptera lunata. with marbled WingS. It 



varies greatly in its markings. Figure 353 represents a
