CERICHRESTUS. 201 



colour is dark fuscous, marked on either side by a broad flavous 

 band, which becomes confluent at the anterior margin ; this band 

 seems to be formed for the most part by thick flavous pubescence. 

 Scutellum triangular, obscure, dark fuscous. Elytra parallel, punc- 

 tate-striate, dull black or very darkly fuscous, tomentose : from the 

 humeral angle is a narrow indistinct flavous line extending halfway 

 towards the apex ; this is very much narrower than in C. exiguus, 

 and is continued (not, as in that species, across the striae and along 

 the margination, but) along the line of the striae. Antennas of the 

 same length as the body, robust, subfiliform, although in the third 

 to the sixth joints there is an evident tendency to incrassation ; black, 

 not piibescent. Legs flavo-fuscous, with the anterior tibiae and tarsi 

 darkly fuscous. 



Several examples of this species have been sent home from the 

 Amazon by Mr. Bates. In the collections of Messrs. Baly, Bates, and 

 the Rev. H. Clark. 



The above description is taken from a male example ; in the female 

 the antennas are not more than two -thirds the length (being hardly 

 longer than the elytra). Other sexual characters also, which we 

 should look for, are apparent : in the male' the body is slightly less 

 robust, and the basal joints of the anterior tarsi broadly and flatly 

 dilated ; there is a manifest dilatation also (when viewed laterally) 

 in the posterior tibioe of the male. 



6. Cerichrestus exiguus. 



C. oblongus, ovatus, subdepressus, niger ; capite brevi, transverso, 

 granulato, inter oculos tuberculis obsoletis ferrugineis binotato ; 

 thorace transverso, ad latera subsinuato, ad basin oblique depresso, 

 punctato, tomentoso, nigro, ad medium longitudinaliter jiavo 

 notato ; elytris latis, parallelis, punctato-striatis, ad humeros 

 longitudinaliter fulvo notatis ; antennis brevibus, robustis, in- 

 crassatis, nigris, art. 9-11 fulvo-Jlavis ; pedibus nigris, femori- 

 bus (ad basin) et tibiis posticis fulvis, ta r sis posticis Jlav is. 



Long. corp. 2i lin., lat. 1\ lin. 



Oblong, ovate, broad, somewhat depressed, of a dull black colour. 

 Head very short, transverse, depressed, almost vertical, not elongated ; 

 between the labrum and the line of the lower margin of the eyes is 

 a transversely concave depression ; eyes prominent, large, distant, 

 situated near to the base of the head ; antennae approximate : the 

 labrum and the maxillary palpi of a dark fuscous colour ; the lower 

 portion of the head fcrrugineous ; immediately above the insertion 

 of the antennae (and caused by an intermediate depression) arc two
