 BY G. LEWIS, P.L.S. 



Monsieur Eene Oberthiir is now engaged in preparing for publi- 

 cation a Catalogue of the Coleoptera of Madagascar, and I hope the 

 notices of two new species given here will reach E-enncs in time for 

 the names and references to be included in it.

Long., 8 mm. 



Oblong-oval, slightly convex above, black, shining ; the head with two short 

 bent strife near the base of the mandibles, not impressed ; the thorax marginal stria 

 very fine, lateral stria also fine, both terminating behind the eye, with a band of 

 punctures more or less confluent, band broadest at and near the anterior angle, nar- 

 rowest behind, no median line or antescutellar mark ; the elytra, subhumeral stria

 disc and basal margin smooth, apical margin impressed ; the pygidiuiu densely 

 punctate ; the prosternum triangular and wide at the base, anterior part with two 

 striae on each side, outer one short and inconspicuous, inner one longer, very distinct
