This is the second species discovered of this remarkable 

 subgenus. It is larger tiian tlie typical species, C. bicoi-nuta, 

 Kolbe, and paler in colour, tiiat insect being described as 

 ferruginous. It has the ordinary form of the species of 

 Jpogonia except for the remarkable prolongation of the 

 clypeus in the male and the greatly dilated tarsi of the same 

 sex. Herr Kolbe mentions the first joint of the front tarsi 

 and the second of the posterior jiairs as most dilated; but in 

 the new species the second joint of all, and of the fruiit tarsi 

 in particular, shows the greatest development. 



Apogonia (subgen. Catagonia) Kolbei, Kraatz. — The 

 species, placed by Dr. Kraatz in tlie subgenus Ceratogonia, 

 was found by Mr. Marshall at Umtali, Mashonaland. The 

 clyjieus is considerably ])roduced in the male, but is only 

 angularly emarginated and not cleft down to the frontal 

 suture as in Ceratogonia. 



The following new species from British East Africa is 

 described here because it typifies another subgenus (for 

 which I propose the name of IN/f/nchogonia), showing yet 

 another type of clypeal formation. In this the clypeus in 

 both sexes is produced into a single acute angle.
