elytra, longer and thinner antennie, larger eyes, shorter tempora 

 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 A'ertical, not foveate. 



4. H. rixator n. sp. — Eather stout, thick and convex; legs, pro- and 

 luesosterna, median parts of the head beneath, antennae and pronotum toward 

 base, rufo-testaceoiis in various sliades; head, pronotum toAvard apex, meta- 

 stunum and abdomen darker, piceous-black ; elytra dark piceous or brownish 

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

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

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

 but convex, 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 tine impunctate line shining an- 

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

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

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

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

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

 striction; basal margin wide, stiongly dilated at the sides; disk alutaceous, 

 reticulate, finely, deeply and closelj- 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. Lrgx moderate, the femora not 

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



Texas (Galveston); New Mexico (Albuquerque). 



The three specimens before me are females, and the species may 

 be readil}' known from the others here described b}^ the dull and 

 rather densel}' 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 the prothorax is much 

 broader and more dilated than in enodis. 



AXTHICITS Payk. 



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

 to some extent heterogeneous, including as it does species of 

 widelv different facies, such as horridua, haldemani and mari^ 

 timui<. They all agree, however, in sternal, abdominal and crural 

 structure and cannot ver^^ well be subdivided in a generic sense, 

 although ma7^i(imits is certainly very aberrant in its oval, sub- 

 connate elytra, with probable absence of hind wings.
