 crebre punctatum : thorax ad apicem baud capite latior, quadratus, 

 ad latera undique apud medium late angulatus, inter hos angulos

This second species of the genus differs from G. auricoma not 

 only in pattern, but also in the simple (not rounded or almost 

 bidentate) angle on the margins of the thorax. 



I have received the species from M. Deyrolle, who obtained 

 it from Malacca; a specimen is in Mr. Baly's collection from 

 Penang.

Genus Dercetis, gen. nov. 



Corpus ovatum, latum, depressum. Caput subporrectum, breve ; 

 oculi ovales ; palpi maxillares elongati, cylindrici, art. penult, brevi, 

 subtiliter incrassato, art. ultimo producto, acuminate. Thorax brevis, 



* I am indebted to Mr. Baly for the generic determination of this species, 

 and also for a reference to Hugel ; as the work is scarce, it may be well to 

 append here briefly the diagnosis of the genus. Antennce ll-articul. fih- 

 formes, art. 5"^ et 6° diffbrmibus : labrum subquadratum, antice rotundatum : 

 mandibulce facie interna excavata, margine dentato : palpi max. 4-articulati, 

 art. 3° 2 primis longiori; ultimo brevi, acuminate : f am 4-articulati, art. 3° 

 bilobo, unguiculis dente late acuto armatis. 



The insects composing the genus are in size small, of parallel form, and 

 notable by the peculiar incrassation of the fifth and sixth joints of the an- 

 tennae of the male.
