The female differs, according to M. Lacordaire, only in 

 having the antennae a very little longer than the body. 

 To this genus I now refer my Zatreplms inscitus,^ although 

 somewhat different in sculpture and pubescence. The lat- 

 ter was described from a female, and has the antenntemuch 

 shorter than the body, and more dilated than in X. 

 trigona {$), the dilatation commencing with the sixth 

 joint. The inner maxillary lobe in the typical species is 

 very long, inserted on the upper part of the maxillary 

 plate, bent at the base, and then crossing the outer lobe 

 between it and the mandible^ and passing outwardly 

 and beyond the mouth, so as to assume the position of 

 the outer lobe ; at the apex it is dilated^ and fringed 

 with longish hairs as in the Callichromince. The maxil- 

 lary palpus is borne on an unusually long pedicel. 

 Neither of these characters appears to be present in X. 

 inscita.

Hab. — Singapore. 



Dark brown, inclining to purplish, with a grayish-ful- 

 vous pubescence in parts ; head mostly pubescent ; 

 prothorax slightly longer than broad, well rounded 

 at the sides, and pubescent, the disk entirely occu- 

 pied by ten perfectly glabrous costte ; elytra elon- 

 gate, a little incurved at the sides and dilated behind, 



* M. Lacordaire (1. c, note) considers it congeneric. He mentions 

 another species from Ceylon.
