elytra, longer and thinner antennje, larger eyes, shorter terapora 

 and in the form of the prothorax. The modification of the genital 

 segment is nearly as in enodis, but the thickened edge of the sinu- 

 ation toward the middle is wider and simply vertical, not foA'eato. 



I. II. rixator n. sp. — Kather stout, thick aud convex; legs, pro- aiitl 

 iiiesosterna, median parts of the licad beneath, antenna; and pronotum toward 

 base, nifo-testaceoiis in various shades; head, pronotum toward apex, meta- 

 sternnm and abdomen darker, piceons-l)lack ; elytra dark piceons or brownish 

 testaceous, gradually slightly paler and more flavous toward base; pubescence 

 ver^' short and sparse but distinct. Head convex, subtjuadrate, as long as wide, 

 truncate and moderately impressed in the middle at base; eyes rather small 

 but con\ ex, much shorter and more prominent than the tempora, the latter 

 parallel behind them for some distance, then rounded into the base; disk dull, 

 densely and strongly strigoso-reticulate, the fine impunctate line shining an- 

 teriorly, the punctures fine but strong, somewhat dense; antennje not quite as 

 long as the head and prothorax, thick, moderately incrassate, the tenth joint 

 distinctly transverse. Prothorax fully as wide as the head, not longer than 

 Avide, strongly rounded and widest at apical fourth, the sides thence strongly 

 oblique and very slightly arcuate to the deep and conspicuous ante-basal con- 

 striction; basal margin wifle, strongly dilated at the sides; disk alutaceous, 

 reticulate, finely, deeply and closely punctate. Elytra scarcely three-fourths 

 longer than wide, distinctly less than twice as wide as the prothorax, the sides 

 parallel and almost evenly, feebly arcuate, broadly obtuse at apex; humeri 

 broadly and transversely exposed at base; sculpture and impressions nearly as 

 in the preceding species, the surface shining. lA'gs moderate, the femora not 

 very stout except the anterior. Length 2.9 mm. ; width 0.95 mm.

The three specimens before me are females, and the species ma^^ 

 be readily known from the others here described by the dull and 

 rather densely punctate head, deep constriction of the prothorax 

 and other characters ; the mesosternum, also, is apparently a trifle 

 more dilated at the sides. The base of tlie i)rothorax is much 

 broader and more dilated than in e)wdis.

Even in its restricted scope, this genus is still a large one and 

 to some extent heterogeneous, including as it does species pf 

 widely different facies, such as horridua^ haldemani and mari- 

 tiTnuii. They all agree, however, in sternal, abdominal and crural 

 structure and cannot very well be subdivided in a generic sense, 

 although maritimus is certainly very aberrant in its oval, sub- 

 connate elytra, with probable absence of hind wings.
