16 . SEKEICOENIA. 



This species resembles C. costulata, Lap. & Gory, in general form, but is more parallel 

 and narrower posteriorly. Head very coarsely punctured. Thorax broadest at the 

 posterior angles, gradually (but very slightly) narrowed towards the front ; the punctures 

 are larger than in C. costulata, and are irregularly scattered over the disk, much closer 

 towards the sides, especially in the place occupied by the longitudinal sublateral 

 impression of C. costulata ; but there is no distinct impression, except close to the base ; 

 the median channel is entire, and strongly impressed. Each elytron has about nine 

 strongly impressed striae (which, however, do not extend to the scutellar region), the 

 interstices very convex, the second and fourth a little more costiform than the others ; 

 the stria? (which do not extend to the base of the elytra) have a series of small punc- 

 tures, with frequent larger punctures, which are brassy and more or less filled with 

 white pile ; the interstices towards the sides have a few small punctures. The apex of 

 each elytron is very obliquely truncated; and both the sutural and outer angle are 

 strongly and acutely dentiform, much more so than in C. costulata.

The species of this genus occur throughout North America as far north as Vancouver's 

 Island and Hudson's Bay, and in Cuba, Brazil, Guiana, &c. In the Old World they 

 are found in Europe, Persia, Mongolia. Several species are also recorded from West 

 and South Africa.

Hob. Mexico. — Guiana, Cayenne 1 ; Amazons, Villa Nova (Bates). 



This species was originally described from Cayenne ; but there is a specimen in the 

 British-Museum collection from Mexico which agrees well with one compared with the 

 type by Mr. Edward Saunders. 



2. Melanophila limbata. 



Yiridi-asnea, aureo micans ; thorace confertim punetato, lateribus parum arcuatis, basi utrinque fovea impressa ;
