Hab. India; China; Java; Sumatra; Celebes; Philippine 

 Islands; Africa (the Cape of Good Hope; the Gambia). 



Specimens of this species received from the Cape and the 

 Gambia agree with the Indian ones in sculpture, but differ con- 

 siderably in colour ; they have the antennae ferruginous, with a 

 few of the apical joints more or less fuscous; the wings are 

 much darker, and the anterior legs only are ferruginous; the 

 apical segment of the abdomen is more or less ferruginous ; but 

 we can only regard this as a climatic variety. 



7. LARRADA CONSPICUA. 



Female. Length 7 lines. Black : the anterior margin of the 

 clypeus, the scape and mandibles, ferruginous, the latter black 

 at their tips; the extreme apex of four or five of the basal joints 

 of the flagellum ferruginous; the face covered with silvery 

 pubescence, which has a faint golden tinge. The tegulse, legs, 

 apical and two basal segments of the abdomen, ferruginous ; the 

 wings yellowish hyaline, the apical margins with a dark fuscous 

 border, the nervures pale ferruginous; the metathorax finely 

 transversely striated : probably in examples in fine condition the 

 thorax would have a covering of pale golden pubescence. The 

 third, fourth and fifth segments of the abdomen are dark fusco- 

 ferruginous, not black.

8. LARRADA ARGYREA. B.M. 



Female. Length 3| lines. Black : the face densely covered 

 with silvery pubescence ; the mandibles ferruginous, covered 

 with silvery pubescence at the base ; the scape of the antenna? 

 rufo-testaceous in front. The metathorax widest at the base, 

 finely shagreened above, the truncation smooth and shining, 

 thinly covered, as well as the sides, with silvery pubescence; 

 the wings hyaline, the nervures and tegula? pale rufo-testaceous ; 

 the tibiae and tarsi rufo-testaceous, the intermediate and pos- 

 terior tibiae with a fuscous stain beneath. Abdomen : the three
