136 EROTYLIDAE. 



gles acute and prominent, base margined from the hind 

 angles to the punctured fossa. Elytra with seven fine se- 

 ries of small punctures , very smooth and shining , jet-black. 

 The shoulder red spot leaves a square black spot on the 

 callus extending to the shoulder. The subapical mark does 

 not touch the suture or margin , it is arcuate on its apical , 

 and undulate on its basal side. The underside is shining, 

 the abdomen punctured , and with some larger impressions 

 on each segment on each side. The prosternum is com- 

 pressed , the front raised into a prominent point, the in- 

 tercoxal process is depressed near the tip , a very little , 

 and wrinkled. Very short metasternal and ventral lines are 

 present. 



There is a specimen of this distinct and fine species in 

 in Mr. Crotch's collection , which is now before me , bear- 

 ing the name I have adopted in this writing, but he did 

 not describe it. This specimen is smaller than , but otherwise 

 perfectly agrees with the specimen in the Leyden Museum.

Hab. Sumatra: Soekadana, Lampongs (J. C. van Has- 

 selt). — One specimen. 



Head with the epistome very thickly, the crown very 

 finely, and the base deeply though sparingly punctate. 

 Antennse short, their third joint equal to the three following 

 in length, the maxillary palpi have the apical joint mode- 

 rately widened (much less as in M. Dehaani) and pitchy- 

 red , the ocular striola well defined , but rather coarse , 

 not prolonged further back than the eye. The front of the 

 head above is brassy with a green tint. 



The thorax is nearly of the same shape as that of M. 

 Dehaani but is more convex , and very shining , the punc- 

 tures are excessively fine, except a few in the neighbour-
