described by Kirby, ^c. 151 



Of the species described by Erichson there are two, which in 

 their general characters must approach very nearly to Kirby's Si. 

 melanarius ; we allude to the Si. incanus and St. cinerascens, in 

 both of which tlie elytra are but little longer than the thorax, and 

 the abdomen sparingly and finely punctured. The first, however, 

 is said to have the forehead deeply hisuicate; the elytra longitudi- 

 nally torulose, and the basal joint of the palpi ])iceous — points 

 which do not accord with Kirl)y's insect. On the whole, the 

 description of St. cinerciscens agrees so nearly with Kirby's insect, 

 that we suspect we might safely remove the note of doubt after 

 that name, given as a synonym ; the phrase " Caput thorace paulo 

 latius, coleopleris dimidio anguslius," however, seen)S to imply that 

 the head is rather narrower, and the elytra somewhat broader, in 

 cinerascens than in melanarius. 



We have seen but one specimen of the St. melanarius — that in 

 the Kirbian Collection. 



The insect which stands as melanarius, Kirby, in Stephens' Col- 

 lection, is the St. unicolor of Erichson, and does not agree with 

 the description given in the " Illustrations." 



We will here notice a nearly allied species,* which we think will 

 prove to be the St. morio, Erichs. 



It has the elytra more ample and the abdomen more thickly 

 punctured than the St. melanarius, and differs, moreover, in the 

 forehead being somewhat concave. This last-mentioned character 

 will likewise serve to separate it from the St. canaliculatus, Er., as 

 well as the absence of the dorsal channel to the thorax. The 

 thorax itself is rather narrower, and this part, as well as the elytra, 

 are a little Lss thickly punctured. In other respects, it much 

 resembles the St. canaliculatus,
