deep, suboblong punctures, becoming much smaller and almost 

 concealed towards apex. Side pieces of metasternum each with a 

 single row of punctures. Basal segment o{ abdomen flat in middle, 

 with a row of large punctures at base, and a few elsewhere, its 

 suture with second quite straight, second with two feeble and irre- 

 gular rows of punctures, each almost concealed by a scale arising 

 from it, third and fourth with lateral punctures only, fifth densely 

 punctate. Hind femora slightly but distinctly dentate, the others very 

 indistinctly dentate. I engtlt 5 3/4-6 mill.

In the table of the genus previously given by me tliis species could 

 not be placed in either of the divisions the renoted, as the 

 elytra are considerably wider than the prothorax, and tlie suture 

 between the first and second abdominal segments is straight. 

 Regarding the latter feature as the more important, it should be 

 placed with egens from whicii it differs in its considerably larger 

 size, practically edentate front femora and peculiar abdomen, the 

 punctures of which will at once distinguish it from most species of 

 the genus. On the elytra of the two specimens before me the scales 

 have hardlv any tendency to form fasciae. 



651. MECHISTOGERUS DUPLICATUS n. sp. 



Black, antennre and tarsi dull red, apical third of rostrum and 

 tibise more or less diluted with red. 



Head, rostrum, antennae andproi/;om,r as in the preceding species, 

 except that the basal third of the rostrum appears to be distinctly 

 tricarinate, with the series of punctures more pronounced. Elytra 

 about one-third wider than prothorax; with series of large, deep, 

 oblong punctures, becoming smaller posteriorly but not concealed. 

 Side pieces of laetasterinun each with a single row of conspicuous 

 punctures. Basal segment of abdomen with large punctures, larger 

 at base than elsewhere, its suture with second quite straight; 

 second with about four or five irregular rows of punctures; third 

 and fourth each with a single row of feeble setose punctures across 

 middle; fifth densely punctate. Hind femora strongly, middle 

 moderately, front slightly dentate. Length 6-7 mill.

Should be placed next to the preceding species, which it very 

 closely resembles, but is at once distinguished from by the abdomi- 

 nal punctures; on the two basal segments they are more than twice 

 as numerous; the present species also has these segments gently 

 convex, whilst in the preceding species although the second slopes
