Sub-Order II. TKK I'BK AMI A.* 



This sub-order U characteri/.ed by the presence in the female of 

 ar-valved borer. The maxillary palpi are three-jointed ; the two 

 liffer soineuhat in structure; the first pair is Mime- 

 uh. .and wider, and usually also thicker: Mmctinu> they 



iiorny: both pairs are elotlu-d with numerous very fine 

 hairs: the front wings have two parallel veins, the hind wiiu 

 ,le vein or none: the veins of the \\ings usually bear c>nspicu- 

 the wings, when not in use, are folded parallel to each 

 other on the abdomen. 



The members of this sub-order are much more agile than t' 



ding. They run rapidly, and spring, by bending under 

 the tip of the abdomen and suddenly straightening it out. 



The Terebrantia includes two families ; these can be separated 



A Females with borer curved downwards. Fam. II. STI Npi i i 



AA. Females with borer curved upwards. Fain. III. COLEOPTRATIDJE, 



Family II. STI:V >ITI:KII >.]:.+ 



In the Stcnopterid.e the wings are narrow and are furnished 

 with one or two longitudinal veins ; but there are no cross-veins. 

 The longitudinal veins are usually fringed with spines. There are- 

 two or three small indistinct segments at the end of the antenna,-. 

 And, as stated above, the ovipositor of the female is curved down- 

 wards. This family includes the greater number of the mcmbe; 

 the order. The following table will aid in determining the gen
