364 MEMOIRS ON THE COLEOPTERA 



Hypermallus compactus n. sp. Shorter and relatively stouter than 

 incertns, robust, very dark castaneous in color, the vestiture short, 

 coarse, yellowish, condensed in irregular areas on the elytra and near the 

 thoracic elevations; legs and antennae dusky rufous; head (cf ) rather 

 finely, not densely punctate; antennae long, a fourth longer than the body, 

 slightly thickened basally, loosely pubescent, with longer stiff hairs 

 beneath, the spines very short and thick; prothorax slightly shorter than 

 wide, the apex not quite as wide as the base, the sides feebly, un- 

 evenly rounded; surface with a central entire and strongly tumid 

 smooth line and, on each side, two tumid smooth spots, the depres- 

 sions with a loose mixture of distinct larger and small punctures; 

 elytra a third wider than the prothorax, not quite two and one-half 

 times as long as wide, the equal apical spines widely spaced; punc- 

 tures widely spaced and only moderately coarse, fine apically; femora 

 mutic. Length (cf ) 15.0 mm.; width 4.5 mm. Texas. 



Allied to incertns but shorter and relatively stouter, with much 

 longer antennae and stronger and closer thoracic punctures. 



Hypermallus militaris n. sp. Form (a 71 ) rather stout, the size small, 

 dark brown in color, the legs and antennae testaceous; head coarsely, 

 densely punctato-rugose; antennae slender, not a third longer than the 

 body, the joints feebly, longitudinally impressed, the third distinctly 

 longer than the fourth but equal to the fifth; prothorax about as long as 

 wide, the base and apex truncate, the former the narrower, the sides 

 evenly arcuate, more converging basally; surface strongly, deeply, very 

 densely punctate, with a wide coarsely punctate, shining median line 

 from base to apical third, the scanty vestiture yellow and forming three 

 narrow loose irregular lines; elytra evidently wider than the prothorax 

 and nearly four times as long, feebly cuneiform, the apices obliquely and 

 narrowly, deeply sinuate, the punctures only moderately coarse, fine 

 apically, everywhere well separated, the pubescence yellowish, scanty, the 

 condensed spots few, small, loose and irregular; last ventral wider than 

 long, trapezoidal, with arcuate apex and rounded angles. Length (d 71 ) 

 11.5 mm.; width 2.5 mm. New York (West Point), Wirt Robinson. 



Much smaller than villosus, with more slender antennae, still more 

 abbreviated outline and more shining and strongly sculptured male 

 pronotum. 



Hypermallus breviusculus n. sp. Form (cf ) still more abbreviated, 

 very small in size, dark brown, the legs and antennae slightly paler and 

 more reddish brown; head strongly, densely punctato-rugose; antennae 

 slender, the joints feebly flattened and densely sculptured and with the 

 usual sharp edge internally, the spines small; joints coarsely, closely 

 punctato-rugose, the third longer than the fourth and equal to the fifth; 

 prothorax shorter than wide, the truncate apex and base equal, widest 

 at the middle, the parallel sides evenly rounded; surface rather coarsely, 

 deeply, densely punctate and somewhat shining, the central smooth 

 spot elongate and with a few coarse punctures, the yellow vestiture
