truncate, with a deep longitudinal impressed line in the middle ; 

 the wings pale yellow, the nervures ferruginous, their apex with 

 a dark fuscous border ; the tibiae ferruginous and set with stout 

 acute spines ; the tarsi fusco-ferrugiuous, thickly spinose. Ab- 

 domen subsessile ; beneath, the margins of the segments rufo- 

 piceous. 



Specimens in fine condition are covered with grey sericeous 

 pile, but it is usually obscure. 



Hab. Port Natal.

112. POMPILUS MOROSUS. B.M. 



Female. Length 6 lines. — Black : the head obscure ferru- 

 ginous, the antennae reddish-yellow beyond the three basal joints. 

 The pro- and mesothorax, the tibiae and tarsi obscure ferrugi-

 metathorax smooth and convex, and the tibiae and tarsi spinose ; 

 the wings yellow, with a broad fuscous border at their apex; the 

 tegulae ferruginous. Abdomen subsessile, its extreme apex rufo-
