which ecnds forward in tlio middle an elongate, extremely slender process between 

 the middle coxa? to meet the metasternum. Middle coxaj very large. Metastcrnum 

 greatly reduced, not so large as the hind coxte. Hind coxiE very large (similar in 

 structure to what obtains in the conTCx South American species of Coproporus, e. g., 

 C oSesiw, Sharp) . Middle femora broad and laminar, their hinder edge deeply 

 channelled for the reception of the tibiaj : these are stout, rather attenuate towards 

 the extremity, strongly spinulose ; the tarsi are broad, and appear like a continuation 

 of the tibia;, the basal joint is particularly large, and is as long as the three following 

 together, the fifth joint is stout and flat. Hind femora, tibite, and tarsi, much 

 resembling the middle ones, but more slender and rather more elongate. Elytra 

 (seen from above) very arched transversely, the humeral angles greatly rounded, the 

 tipper superficies bounded by a fine line which extends from the hinder outer angle 

 to near tlie large scutellum ; the hinder external angle is a little produced, so as to 

 be acute, their suture is fine and accurately fitted, and is without stria. Seen from 

 beneath, the external portions of the elytra project greatly as a broad free border be- 

 yond the sternum, this border is marked off by a very distinct raised line, which exists 

 on tlie inner face of the elytron, and accurately adapts itself to the side margins of 

 the sternum. Ilind-body broad and short, much attenuated towards the extremity, 

 the sides distinctly margined, the segments capable of being almost entirely retracted 

 witliin one another : its structure very similar to that of the convex Copropori, this 

 being the case also with the ocdeagus and its sheathing segment. The antenna; are 

 not described, because only the two basal joints exist, these are rather short, the 

 basal joint being ratlicr thick in proportion to its length.

Long. Corp. extens. 8\ mm. 



Head about 1 mm. broad, black, impunctate. Thorax about 3^ mm., broad, and 

 about 2 in length, with a few very indistinct punctures scattered over its surface. 

 Scutellum impunctate. Elytra about as long as the thorax, impunctate, moderately 

 shining, (heir hind margin pitchy. Hind-body pitchy, with the hind-margins of the 

 segments and the apex paler ; the segments above fi:iely, very evenly and rather 

 closely punctm-ed, and clothed with a very short and even yellow pubescence : the 

 under surface similar to the upper, except that it has the basal segment coarsely 

 punctured, and its pubescence is developed into coarse spines. Logs pitchy. In the 

 male, the dorsal plate of the 7th segment of the hind body ends in four obtuse teeth, 

 the ventral plate has a broad and rather deep sub-angular notch at the apex ; the 

 hind margin of the ventral plate of the preceding segment is a little trisinuate, and 

 it is slightly depressed along the middle, and its pubescence arranged so as to give it 

 an obsolete grooved appearance.
