78 MEMOIRS ON THE COLEOPTERA 



sides of the buccal opening, which is of the usual depth; antennae 

 more or less slender, with the tenth joint rather abruptly wider. 

 [Type Pelecyphorus muricatulus Lee.] Stethasida 



21 Body oblong-oval, moderately convex to subdepressed above, 

 generally covered with a closely adherent earthy incrustation and 

 with short recumbent hairs, sometimes clustered more densely on 

 the elevations, the elytra with distinct reflexed humeri and acute 

 side margins, the surface with interrupted, very sinuous and ir- 

 regular raised lines or spots, which generally differ sexually, the 

 base of the prothorax having a feebly impressed rounded median 

 lobe and a rather deep sinus at each side; mentum entirely filling 

 the buccal opening, without evident pedestal; antennae slender, 

 with the tenth joint abruptly wider; anterior tibiae everted and 

 acute at tip, slightly serrulate externally; tarsi rather short but 

 slender, with short and coarse inclined hairs beneath; prosternum 

 more or less porrect and deplanate between the coxae. [Type A. 

 grisea Fabr.] *Asida 



Body throughout nearly as in Asida but with the prosternum between 

 the coxae convex and rapidly declivous to the mesosternum, differing 

 profoundly in the structure of the antennae, which are slender, with 

 the tenth and eleventh joints subequal in size and abruptly larger 

 than the preceding, being unique in this respect in the tribe; anterior 

 tibiae bent apically but perhaps only in the male. [Type G. car- 

 tagenica Escal.] *Globasida 



Body more elongate and subparallel, moderately convex, the prothorax 

 and oral organs nearly as in Asida. the elytra with a single even discal 

 costa on each and acute side-margins, the integuments clean and 

 not incrusted, the sinuous irregular elevations wanting; anterior 

 tibiae strongly everted and acute externally at apex; tarsi unusually 

 elongate, with small stiff setae beneath; antennae differing wholly 

 from those of the two preceding, stouter, feebly and very evenly 

 increasing in width to the apex of the tenth joint. [Type A. gadi- 

 tana Escal.] *Alphasida 



Besides these generic groups several others have been proposed, 

 which it is not possible to include in the table because of the lack of 

 special data concerning them. As to Stenomorpha Sol., its type, 

 costata, which is not a Euschides, does not prevent the latter genus 

 from being maintained, although LeConte gave the name as a sub- 

 stitute for Stenomorpha, on the ground that the latter name was 

 preoccupied by Stenomorphus . In this I cannot agree, and believe 

 that it should not be held to be preoccupied. Still less should 

 Stenosides Sol., be considered unavailable, either because of its 

 impropriety or its resemblance to Stenosis, as suggested by Lacor- 

 daire; but, for much the same reason as in the case of Euschides and 

 Stenomorpha, the genus named Ologlyptus by Lacordaire, which is
