adapted for seizing other insects like the raptorial Ilemiptera, 

 and which has given them the name of Soothsayers and 

 Prophets, from their devotional attitude when

 long, and the broad wings are thin, net-veined, 

 with long parallel veins, more strongly resem- 

 bling the Neuroptera in this respect than any

 eighth sternite, the oviduct opening between 

 the seventh and eighth segments. The ninth 

 segment is complete. The elements of this 

 ring are but little developed, scarcely surpass- 

 ing the subgenital plate ; the two episternites 

 are distinct, and between them is the small 

 ninth sternite." The stylets are concealed by 

 the broad expanded sternum of the seventh 

 segment, while the antenna-like appendage (or 

 anal style, Fig. 23) is sometimes many jointed,

 mass of eggs laid by the female is attached to twigs, and 

 enclosed in a flattened subovate case (ootheca) of hardened 

 silk. The eggs are infested to some extent by chalcid para-
