Fam. NitidulidaB. 



Genus Caepophilus. 



Stephens, 111. Brit. Ent. iii. 50 (1830). 



Carpophilus dimidiatus'^ . 



Nitidula dimidiato. Fab., Ent. Syst. i. 2G1 (1792). 

 Carpophili/s mirapilosus, WoU., Ins. Mad. 117 (1854). 

 dimidiatus, Murray, Mon. Nitid. 379 (1864). 



A widely cliftusecl insect, which appears to have been natu- 

 ralized, through the medium of commerce, in most parts of the 

 civilized world, and which has established itself in the Ma- 

 deiran, Canarian, and Cape- Verde archipelagos. It has been 

 taken by Mr. Melliss at St. Helena, but is, of course, totally 

 unconnected with the true fauna of the island. 



Car2)op}iilus hemijoterus'^ . 



Dermestcs hemipterus, Linn., Syst. Nat. ii. 567 (1767). 

 Carpophilus Jiemipterns^ Murray, Mon. Nitid. 362 (1864). 

 , WolL, Col. Atl. 108 (1865). 



Likewise captured by Mr. Melliss at St. Helena, and equally 

 diffused with the last species (through human agencies) over 

 the civilized world. It is common, chiefly in the warehouses 

 and stores, throughout the Madeiran, Canarian, and Cape- 

 Verde groups. 



Fam. Trogositidae. 



Genus Teogosita. 



Olivier, Ent. ii. 19 (1790). 



Trogosita mauritanica* . 

 Tenehrio mauritanicus^ Linn., Syst. Nat. ii. 674(1767). 

 Trogosita mauritanica, Woll., Col. Atl. 116 (1865). 

 , Id., Col. Hesp. 66 (1867). 



Of com-se totally unconnected with the true fauna of the 

 island, yet, having been taken by Mr. Melliss, it would seem 

 at any rate to have established itself in the storehouses and 

 granaries of St. Helena, in like manner as it has done in most 

 regions of the civilized world. It is very common throughout 

 the Madeiran, Canarian, and Cape- Verde archipelagos. 



Fam. Cucujidae, 



Genus SiLVANUS. 



Latreille, Gen. Crust, et Ins. iii. 19 (1807).

A single example of this almost C(.isinopolitan Sihanus is
