TENEBRIONID^: 95 



Body oblong, more parallel, somewhat as in Asidopsis opaca; prothorax 

 as broad at base as at the middle, the surface smooth, the hind angles 

 acute, overlapping the humeral angles of the elytra, which are dis- 

 tinct; elytra parallel anteriorly and rather distinctly wider than the 

 prothorax, the sides rounding inwardly behind, the surface closely 

 and somewhat irregula'rly sulcate; abdomen finely, evenly and not 

 densely punctate; prosternum moderately wide between the coxae, 

 obtuse or truncate at tip, the propleura punctate; epipleura well 

 defined; met-episterna a little longer than wide. Length 15.0 mm. 

 Texas (Llano Estacado) sulcipennis Lee. 



The two species morata and sulcipennis, the latter still represented 

 by the unique in the LeConte collection, are only provisionally 

 attached, as they will certainly form one distinct genus and prob- 

 ably two, by reason, among others, of the radically different form 

 of the basal thoracic angles. It is probable that the Mexican 

 robusta Horn, is congeneric with morata. 



Glyptasida n. gen. 



This genus is obviously distinct from its neighbors in several 

 structural features, as well as in facies, the latter being peculiar 

 and unremindful of any other type of the tribe. It is allied to 

 both Pycnonotida and Pelecyphorus, agreeing with them in the 

 small and nearly flat retractile ligula, and, in addition, is similar 

 to the latter in the large scalene last palpal joint of the male and 

 in its broad inflexed sides of the elytra; it differs from Pycnonotida, 

 Microschatia and others of that small group of genera in both of 

 these characters. The body is oval or oblong-oval, of rather large 

 size, the labrum moderately transverse and evidently sinuate 

 medially at apex, the mentum rather large and unusually parallel- 

 ogramic, with the sides nearly parallel, and the apex has a small 

 deep median emargination; the pedestal is short but evident and 

 the sides of the buccal cavity are unusually abbreviated. The 

 antennae are moderately thick, bristling with very stout erect short 

 setae and the tenth joint is rather abruptly wider than long, deeply 

 sinuate at the middle of the apex, with the spongiose spots extending 

 laterally and sometimes becoming rather approximate on the sides, 

 the eleventh small, rapidly obconic and transversely truncate and 

 spongiose at apex. The maxillary palpi often have the large scalene 

 terminal joint of the male peculiarly modified by apical emargination 

 or excavation, but whether this is in any way accidental or is normal
