LEPIDOPTERA, 



227 



In Texas and Arizona there occur several species of 

 Triprocris (Trip^ro-cris). The venation of one of them is 

 shown in Figure 268. 

 It is remarkable in that 

 none of the branches of 

 radius of the fore wings 

 coalesce beyond the dis- 

 cal cell. 



The gtnus Harrisina 

 (Har-ris'i-na) seems to 

 be closely allied to the 

 preceding and is placed 

 in this family provision- 

 ally. It differs, how- 

 ever, from the typical 

 form of the family in jo^^*"'^^^^ ^^^^ 



that the anal area of Fig. 267.— wings of Pyro^norpka dimidiata. 



the hind wings is greatly reduced, there being only two, 

 short, strongly curved anal veins. As in the other members 



1112 „, of the family there are 



^ni4 two, well-developed anal 

 l^^^s veins preserved in the 

 fore wino;s. 



In the East the most 

 common species is Har- 

 risina ainericana (H. 

 a-mer-i-ca^na) (Fig. 269).

The wings are long and narrow; the abdomen is long and 

 widened towards the caudal end. It is greenish black in 

 color, with the prothorax reddish orange. The larva feeds
