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-

The genus Harrisina 

 (Har-ris'i-na) seems to

 preceding and is placed 

 in this family provision-

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

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



of the family there are 

 J 11 * two,well-developed anal 

 I 111 * veins preserved in the 

 fore wings. 



In the East the most 

 common species is Har- 

 risina americana (H. 

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