adapted for seizing other insects like the raptorial Hemiptera, 

 and which lias given them the name of Soothsaj-ers and 

 Prophets, from their devotional attitude when 

 watching for their prey. They are worshipped

 head is horizontal, triangular in front, with 

 long filiform antenna ; the prothorax is very 

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

 with long parallel veins, more strongly resem- 

 Ijling the Xeuroptera in this respect than any 

 other family. The abdomen is long, linear

 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, 

 and is said by Lacaze-Duthiers to be appended

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