fined in the male but parallel and loosely 3-jointed as usual ; pronotum not 

 impressed but finely, strongly margined at base, the fovete minute and almost 

 completely obsolete, the sides even, with a rather thick margin, which becomes 

 gradually very thick at the apical angles but continuously so, the apical callus 

 not posteriorly delimited or truncated — as it is in Cryptophagus ; elytral suture 

 margined except toward base ; mesosternum rather more concave between the 

 coxae than usual, the tibiae compressed and somewhat triangular, the tarsi and 

 claws slender as usual. [Subtribe Antherophagi] Antherophagus 



Eyes basal, convex, prominent and more or less coarsely faceted ; tibiae slender 2 



2 — Front declivous and concave between the antennae, the edge not beaded over the 

 insertion of the latter 3 



Front declivous but evenly, longitudinally convex anteriorly, the edge sharply angu- 

 late but not beaded over the antennae, the frontal margin with a broadly, pos- 

 teriorly angulate smooth space, probably homologous with the emargination of 

 Antherophagus ; antennae moderate, the club loosely 3-jointed, with the last joint 

 obliquely and obtusely narrowed from near the base, the first joint small and 

 globular ; prothcwax with a broad flat marginal bead at base, before which the 

 surface throughout is feebly impressed, the foveae wholly obsolete ; sides with a 

 thickened nodal point at the apical angles but otherwise perfectly even, the nodal 

 points projecting anteriorly, the apex broadly emarginate between them as in 

 Emphylus ; punctures fine and irregular, the pubescence short, coarse and closely 

 decumbent ; subsutural lines of the elytra not extending to the base ; mesoster- 

 num not at all impressed between the coxae. [Subtribe Spanioph^NI.] 



*Spanioph£enus 



Front flat and not more declivous anteriorly ; antennal club normal and 3-jointed, its first 

 joint not differing in form from the second though frequently smaller in size; body 

 strongly punctured and rather coarsely pubescent. [Subtribe Cryptophagi]...4 



3 — Antennae stout, almost similar to those of Antherophagus but with the second joint 

 wider than the third, the 3-jointed club narrow and feebly delimited, and with its 

 basal joint smaller than the second though similar in form ; prothorax not impressed 

 at base, the sides even, with a fine acute edge, the apical angles broadly, obliquely 

 truncate and prominent but only slightly thickened, the apex broadly sinuate be- 

 them, the basal foveae and transverse impression obsolete ; elytral suture mar- 

 gined toward tip ; body subglabrous and strongly alutaceous, very finely, feebly 

 and moderately closely punctured. [Subtribe Emphyli] Emphylus 



Antennae slender, the basal joint elongate-oval, not very thick, the second still nar- 

 rower, elongate, broader than three to eight, which are very slender and elongate, 

 the club narrow, loosely 3-jointed, gradually formed, the ninth joint being slender 

 elongate and obconical, altogether dissimilar in form to the tenth and unique in 

 the family ; prothorax very feebly impressed transversely at base between the 

 large but feeble foveiform depressions, the sides broadly and feebly triundulate, 

 the edge thickened but not very prominent at the undulations, which are at the 

 apex and near apical and basal third, the apical angles not modified, the apex 

 broadly arcuate from side to side ; elytral suture margined, very obsoletely so to- 

 ward base ; body coarsely apulptured and pubescent, nearly as in Cryptophagi.
