TENEBRIONID/E 83 



Antennae broadened apically only through the tenth joint, the ninth 

 nearly similar to the eighth 2 



2 Body stout, more oval and more convex, densely coated, the fine 

 ridges and elevations with small, close-set tubercles appearing through 

 the coating like strings of small beads; head more feebly impressed, 

 the occipital impression nearly obsolete, the epistoma more broadly 

 and clearly sinuate, the antennae not longer than the width of the 

 head; prothorax more transverse, more than one-half wider than 

 long, widest slightly behind the middle, where the sides are less 

 prominent and more broadly rounded, strongly converging and not 

 sinuate thence to the deeply but narrowly sinuate apex, feebly 

 converging but deeply sinuate to the transverse base, which is 

 flexed a little posteriorly laterally, the angles thus acute and sensibly 

 prominent, the apical narrowly rounded; surface broadly, feebly 

 concave laterally, tumid medially, the median line narrowly, sub- 

 evenly impressed except near base and apex; elytra broader, more 

 oblong, widest slightly behind the middle, the side-margins distinct 

 but not carinate or tuberculose, rapidly rounding posteriorly, be- 

 coming almost transverse to a slightly more elevated junction with 

 an oblique rumus from the suture, the median ridge feeble, irregular, 

 much disintegrated anteriorly, flexed inward posteriorly to a tubercle 

 at the middle of the ramus; suture not elevated and with numerous 

 anteriorly oblique and very feeble branches; humeral angles exposed 

 but obtuse; legs short, rather slender, evidently micro-setulose; 

 tibiae nearly as in contortus. Length 14.7 mm.; width 7.5 mm. 

 Texas regularis Horn 



Body smaller, the elytra shorter and relatively more inflated, black, the 

 coating dense, the surface anteriorly densely granulose, but, on 

 exposed spots of the elytra, smooth with small sparse punctures 

 and granules; head nearly as in contortus but with the impressions 

 feeble, the antennae barely at all longer than the width of the head; 

 prothorax as in contortus, except that the median line is more nar- 

 rowly and evenly impressed almost throughout the length and 

 the rectilinearly truncate base is flexed abruptly posteriorly at the 

 sides, causing the hind angles to be posteriorly prominent and more 

 acute; elytra two-fifths longer than wide, the sides more parallel 

 and more arcuate than in contortus, more nearly as in regularis, 

 widest near the middle, the side margin irregular and uneven but 

 not tuberculose, the subapical formation somewhat as in regularis 

 but with the entire surface coarsely reticulate or clathrate, the 

 dividing ridges of the cells acutely elevated, thin and rough, the 

 medial ridge well defined but not more elevated than the transverse 

 ridges, the suture feebly elevated, more narrowly than in contortus; 

 humeri exposed, obtusely angulate and feebly reflexed; legs and tibiae 

 nearly as in the other species, short, rather slender, the parts cylin- 

 dric; prosternal process much more deflexed posteriorly than in 

 either of the others, not prominent, the sloping posterior part im- 

 pressed. Length 11.5 mm.; width 5.8 mm. Texas.
