RUTELIISLE 6l 



Alamona n. gen. 



In this genus the ascending mes-epimera are slender and the 

 tumidity of the mesosternum between the coxae small, not at all 

 pronounced and it is anteriorly pubescent. The body is stout, 

 oblong, the pronotum devoid of any trace of lateral fossae or medial 

 sulcus, the ligula moderate in size, somewhat trapezoidal and con- 

 cave and the subquadrate elytra have about thirteen feeble striae. 

 The tooth of the anterior tibiae is very large, acute and conspicuous 

 and, as a primary distinguishing feature, the hind tibiae are very 

 short, stout and rapidly obconic. The larger claw of the anterior 

 male tarsi is of the usual type in the Strigodermids, being stout, 

 with the upper ramus very small, short and slender. We ap- 

 parently have two species, which may be defined as follows, the 

 type being parviceps: 



Body stout, oblong, convex, moderately shining, black beneath, the legs 

 piceous, the hind femora paler; head, pronotum and scutellum nearly 

 black, with moderate violaceous lustre, the sides of the pronotum 

 pallid and also the basal margin medially, the elytra pale and bright 

 tawny-flavate, with an inferior streak behind the humeral callus and 

 the side margin posteriorly and also at base, blackish; head notably 

 small, much less than half as wide as the prothorax, densely punctato- 

 rugose, the clypeus less than twice as wide as long, flat, with moder- 

 ately reflexed edges, rather broadly rounded angles and sides diverg- 

 ing but slightly basally, the suture fine but very distinct: eyes small, 

 not prominent; antennal club evidently shorter than the stem; 

 prothorax less than one-half wider than long, the sides parallel and 

 nearly straight, becoming strongly convergent and nearly straight 

 in apical third to the rather sharply defined and moderately promi- 

 nent angles, the basal angles nearly right and scarcely more than 

 blunt; base lobed medially and with an entire bead; surface rather 

 coarsely but shallowly and closely punctate throughout, except along 

 the smooth flat punctureless median line attaining base but not the 

 apex; pubescence erect, rather abundant and gray; scutellum punc- 

 tate except broadly along the middle; elytra glabrous, quadrate, 

 barely as long as wide, two-fifths wider than the prothorax, the sides 

 parallel and arcuate, more rounded broadly around the humeri, 

 the apex broadly arcuate in about posterior third; surface shining 

 but rugulose, the striae feebly impressed, distinctly but not deeply 

 punctate, the coarse post-humeral dark streak more impressed and 

 scabrous; pygidium large, convex, shining, sparsely pubescent and 

 with fine loose superficial sculpture; under surface and femora with 

 abundance of long erect pale hairs; hind tibiae very much shorter 

 than the femora or tarsi, distinctly less than twice as long as wide. 

 Length (cf ) 8.0 mm.; width 4.7 mm. Texas (Del Rio), Wickham.
