SCOLIIDjB. 



Family SCOLIIDJE. 



Fossorial Wasps of varying size, none minute, some very large ; 

 bodies heavy, massive in the female, more slender in the male ; man- 

 dibles strongly arched, large in proportion, and often considerably 

 wider about the middle than at the base ; antenuse in female short, 

 cornute, or arched, in male longer, filiform ; eyes either emarginate 

 or simple ; ocelli always present, in a triangle on the vertex. Thorax 

 of moderate length, the posterior angles ot the pronotum prolonged 

 back to the base of the wings ; median segment equal to or shorter 

 than the mesonotum, rounded, truncate, sometimes emarginate pos- 

 teriorly ; legs short, stout, and (except in the males of Tiphia and 

 Myzine) more or less densely clothed above with stiff hairs and 

 spines ; intermediate coxae widely separated ; intermediate tibiae 

 with one apical spur * ; the apex of the posterior legs generally 

 not reaching up to the apex of the abdomen ; wings broad and 

 ample, the ueuration in certain genera stopping at a considerable 

 distance from the apical margin of the wing ; fore wing with one 

 radial, and at least two cubital cells, the 1st discoidal cell not 

 particularly lengthened, always shorter than the medial cell. 

 Abdomen generally massive and long, the 1st ventral segment 

 always separated from the 2nd by a deep constriction or furrow ; 

 the apex in the male furnished with one or more spines.
