38 Mr. G. C. Champioa on the Heteromerous Coleoptora 



Numerous examples. Allied to S. conspicillata and 

 S. pulchella, Miikl., from Central America, but very 

 differently coloured. The thorax is without marginal 

 carina, and the tibit\3 are ungrooved on their outer edge. 

 There is very little difference in the form of the antenna3 

 in the sexes, those of the female being merely a little 

 shorter.

Sosthenes parvulus, n. sp. 



Moderately elongate, rather depressed, very shining, glabrous ; 

 greenish-feneous, the humeri indeterminately brownish, the 

 labrum, oral organs, legs, and antennae testaceous, the latter with 

 the apical three joints piceous. Head very broad and short, 

 sparsely, finely punctate ; the eyes prominent, coarsely granulated ; 

 antennfe short, scarcely reaching the base of the prothorax, slender, 

 the apical three joints widened and forming a loose club, 9 and 10 

 transverse. Prothorax as wide as the head including the eyes, 

 transversely cordate, much narrower at the base than at the apex ; 

 somewhat coarsely and moderately closely punctate, the punctures 

 becoming coarser and more crowded at the sides. Elytra a little 

 more than twice the length of the prothorax, and slightly wider 

 than it, truncate in front, subparallel to the middle and arcuately 

 narrowing thence to the apex, deeply transversely depressed below 

 the base, the basal portion, except along the suture, appearing 

 transversely swollen ; finely punctate to a little beyond the middle, 

 the punctuation close and confusedly arranged near the suture, 

 becoming denser at the base, scattered and subseriately arranged 

 towards the sides, and completely obsolete on the declivous apical 

 portion. Beneath with scattered punctures on the abdomen and 

 metasternum, those on the latter coarse, the prosternum and pro- 

 pleurae very coarsely punctured. Length li mm.

A single specimen. In its structural characters this 

 minute species agrees with the type of the genus, 

 S. dychirioides, Champ., from Guatemala, from which it
