This species bears a strong resemblance to Eumelepta bipla- 

 giata, and is in fact of entirely similar coloration , but the al- 

 together different structure of the antennae and the longer first 

 joint of the posterior tarsi will at once distinguish it; I have pla- 

 ced this species provisionall}^ in Baly's genus Charaea with which 

 it agrees in the principal structural characters, I am however 

 unable to discover any spine at the anterior tibiae, the posterior 

 ones being distinctly mucronate ; the second and third joints 

 of the antennae are very small ; a single specimen which 

 probably represents the female , is larger , the third joint of 

 the antennae is a little longer, the thorax more transversely 

 shaped and the elytral pale mark is much smaller and less 

 elongate. 



146. Mialaeosonra nig-rieolle, n. sp. 



Flavous, the thorax , knees and the abdomen black; thorax 

 transverse, closely and strongly punctured, elytra pale flavous, 

 punctured like the thorax. 



Length 2 lines. 



Head with a few very minute punctures at the vertex , the 

 latter with a shallow longitudinal central groove , eyes large 

 (the lower half black, the upper half white) frontal elevations 

 strongly raised , bounded behind by a deep transverse groove, 

 clypeus thickened, black, labrum flavous, mandibles black, palpi 

 rather robust, piceous, antennae rather robust, extending to 

 about half the length of the elytra, fulvous, the third joint 

 longer than the second , but one half the length of the fourth 

 joint; thorax nearly twice as broad as long, the sides rounded 

 narrowly margined, the anterior angles slightly produced, the 

 surface very strongly and closely punctured , the interstices 

 slightly rugose; scutellum large, flavous ; elytra slightly wider 

 at the base than the thorax, as closely and strongly punctured 

 as the latter part; below flavous, the knees and the abdomen 

 black ; tibiae with a small spine, the first joint of the posterior 

 tarsi as long as the following two joints, claws appendiculate ;
