Coleopterological Notices, IV. 5G3 



Vestiture consisting of large, broad, moderately dense scales ; punctures of 

 the pronotum large, deep, circular and distinct, with a narrow carinate 



impunctate line ; basal denuded spots not distinct 3 insolita. 



Antennal club more robust and conoidal, shorter and with the basal joint 

 constituting one-half of the mass ; vestiture consisting of more or less 

 broad scales, more densely placed, not conspicuously oblique at the sides 

 of the elytral intervals ; body more convex, the prothorax never with sub- 

 denuded spots at the sides beneath. 

 Abdominal impression of the male normally clothed with long recumbent 

 scales ; body very robust ; basal denuded spots of the pronotum large 



and distinct 4 COinpacta 



Abdominal impression of the male bristling with erect robust and pointed 



hairs ; body narrow and subcylindrical ; basal subdenuded spots of 



the pronotum almost completely obsolete. 



Antennal club robust, much wider than the outer joints of the funicle ; 



anterior coxae separated by about one-third of their own width ; elytral 



striae indicated by narrow partings of the vestiture 5 texaiia 



Antennal club exceedingly small, scarcely wider than the outer joints of 

 the funicle ; anterior coxae separated by one-half of their own width ; 

 elytral striae totally obliterated by the vestiture, the latter excessively 

 dense and composed of much broader scales ; body still narrower.

Oblong, parallel, moderately narrow, black throughout, rather 

 dull in lustre and uniformly clothed with long fine hair-like recum- 

 bent squamules, pure white in color, but rather sparse and produc- 

 ing merely a grayish pruinose appearance, the scales at the sides of 

 the elytral intervals strongly evenly and posteriorly oblique. Beak 

 densely punctate, fully as long as the prothorax in the male, a little 

 longer and rather slender in the female, the antennal club robust, 

 oval, densely pubescent, as long as the five preceding joints in the 

 former sex, but a little shorter in the latter, the basal joint but 

 slightly more than one-third the total length, the second funicular 

 joint one-half longer than the third. The male is generally larger 

 than the female, and, in both sexes, the median parts of the third 

 and fourth ventral segments are abruptly denuded. The prosternum 

 is rather narrowly but distinctly impressed along the middle, the 

 anterior coxa^ being separated by about one-fourth of their own 

 width. Length 3.0-4.4 mm. ; width 1.2-1.75 mm.
