Black ; antciinie and tarsi of a diiij^y red. llatlior s|)arsfly 

 clothed (denser on sterna and legs than elsewhere) with 

 (lin^ry greyish and sooty scales. 



Ui'dd with coarse crowded punctures. l-'yes separated 

 less than width of bascM)!" rostrum, a rather narrow and (lce[) 

 bnt partially concealed depression behind each. Rostrum 

 moderately long ; basal third with coarse, partially con- 

 cealed punctures, elsewhere with smaller (but not very 

 small) sharply defined ones. Pmtliorav moderately trans- 

 verse, sides stronglv rounded, subapieal constriction stronger 

 tlian usual ; with dense, large, round, non-eonHuent punc- 

 tures ; uicdiiiu carina distinct, hut somewhat irregular in 

 middle. Klijtra cordate, about one-fourth wider than pro- 

 thorax, sul)humeral incurvature very feeble; with very 

 coarse sculpture. Metuslenuim with a strong ridge on each 

 side between eoxre ; punctures of episterna interrupted. 

 Abdomen with dense and rather coarse punctures, not in 

 regular rows on third aiid fourth segments. Leys stout ; 

 fenu)ra moderately grooved and rather strongly dentate; 

 bind tibiic strongly dilated to apex, the others lightly so.

In general appearance strikingly like some of the larger 

 species of Meluuteriiis (e. g., semiporcatus). On the basal 

 half of the elytra the punctures arc unusually coarse, large, 

 and long, so that from base to middle there are only from 

 four to six in each row; the interstices there are also much 

 narrower than the punctures, and on some specimens are 

 irregularly depressed between two of the punctures, so that 

 these appear to be semi-double. On the basal half also the 

 transverse ridges between the jjunctures are on a level with 

 the interstices, so that striae are really absent ; on the apical 

 half, however, the striation is distinct, and the punctures, 

 although large, are considcraljly smaller, and without a 

 semi-double appearance. The basal segment of the alxlomcn 

 is gently depressed in the middle in the male and very feebly 

 convex in the female ; otherwise the sexes are scarcely 

 distinct.
