margiu near the posterior angles ; the disc with five im- 

 pressions: one at each of the four angles, the fifth before 

 the middle of the hind margin and with a slightly- 

 raised longitudinal line at its bottom. The elytra narro- 

 wed beyond the middle , the tip rounded , subopaque , the 

 broad portion closely covered with distinct punctures ; a 

 slightly raised longitudinal line runs , not quite in the 

 middle , nearly parallel with the outer margin , joining the 

 inner margin at two thirds of its length ; an impression 

 along the outer margin from the prominent shoulder as 

 far as the narrowed portion of the elytra ; the narrowed 

 portion itself slightly impressed , its margins , especially 

 the apical one, raised. The anterior tibiae slightly com- 

 pressed, somewhat enlarged. The sides of the abdomen 

 nearly parallel ; the apical segment at its base as broad as 

 the hind margin of the penultimate segment , not quite as 

 long as broad at its base, its sides somewhat convergent, 

 at the basal half slightly convex; the disc impressed in 

 front of the incision ; the incision angular , not reaching 

 the centre of the segment, its sides slightly curved out- 

 wardly.

5. Ichthyurus Gestroi, sp. n. cT and Q. 



Of this species, captured in 1870 by Dr. 0. Beccari at 

 Keren (district Bogos, North Abyssinia) on the flowers of 

 Cissus quadrangularis Schimp. ^), I received both sexes 

 through the kindness of Dr. R. Gestro of Genoa, under 

 the name of Ichthyurus discoidalis Westw. However the 

 received male specimen shows some such striking particula- 

 rities of which no mention is made in the description of
