GTNANDEOPHTHALMA.— MEaALOSTOMIS. 29 



From G. agilis, to which this species is closely allied, it is distinguished by the 

 colour and shape of the elytral spot, which leaves the base itself black, while this part 

 is constantly rufous in G. agilis.

A species differing from G. agilis by its smooth and shining thorax and elytra.

A variety from Guanajuato is before me, which has the elytra uniformly fulvous, 

 and the suture and lateral margin, as well as a small spot at the shoulder, black ; the 

 other marks are absent. The whole difference between this species and G. leucognatha 

 seems to be the shining green markings of the elytra, which are black in the other 

 species, their shape being variable. This variety may possibly belong to a different 

 species. Lacodaire's type of G. quadripartita was a female. Several males which I 

 refer to this species are before me, but they do not differ materially.

Subfam. MEGALOSTOMINM 



This subfamily, containing five genera, is restricted to the New World. Four of 

 these are represented in Central America. 



MEGALOSTOMIS. 



Megalostomis, Lacordaire, Me'm. Liege, v. p. 519 (1848). 



Thirty-four species of this fine genus are known, but six only from Central America. 

 The genus has been divided by Lacordaire into three subgenera ; but their characters
