kled, the discal costiB scarcely visible, the submarjiiual distinct. Pygidium 

 coarsely and sparsely, somewhat irreguhirly punctured. Metasternum densely 

 punctured, the hair moderately long and dense. Abdomen rather closely i^unc- 

 tured at the sides, the last two segments more coarsely punctured. Last joint of 

 maxillary palpi fusiform, not impressed. Claws arcuate, the tooth strong, dis- 

 tinctly in front of middle. Length .65 inch ; 17 ram. 



Male. — Antennal club as long as the stem. Abdomen rather 

 deeply channeled at middle and with moderately long hair arising 

 from distinct punctures, penultimate segment acutely notched at 

 middle (fig. 17) the last segment abruptly triangularly depressed, 

 the floor of the impression terminating in two rounded lobes between 

 which is a moderately deep acute notch. Inner spur of hind tibiie 

 moderate in length, projecting slightly obliquely from the tibia, the 

 outer spur longer. 



Of this species I have but one male before me, but several others 

 in the cabinet of Dr. LeConte have been examined. It resembles 

 congrua supei-ficially so closely that they can hardly be distinguished 

 except by the sexual characters. 



The claws are remarkable in having the tooth slightly in front of 

 the middle, the posterior poition of the claw broader than usual. 

 The hairy abdomen is unique. 



Occurs in Texas. 



19. l(. congrua Lee. ^Oblong, moderately robust, rufocastaneousto piceous, 

 shining. Clypens feebly emarginate, the border moderately reflexed, surface 

 moderately coarsely and densely punctured, front rouglily punctured. Thorax 

 narrowed from base to apex, more obliquely in front, the margin entire, sparsely 

 ciliate, disc moderately coarsely, evenly not closely punctate, a distinct channel 

 along the basal margin from the hind angles nearly to middle. Elytral punc- 

 tures coarser and closer than those of the thorax, less deeply impressed, the sur- 

 face slightly wrinkled, the costae very indistinct, the tirst discal usually the only 

 one visible beside the sutnral. Pygidium coarsely sparsely and indistinctly 

 punctate, the apex truncate. Metasternum densely rather finely punctate, the 

 hair long, dense and silken. Abdomen sparsely finely punctured at the sides, 

 the last two segments much more coar.sely punctate. Last joint of maxillary 

 palpi fusiform, not impressed. Tarsal claws arcuate, the tooth moderately large, 

 median and acute. Length .58 — .75 inch ; 15 — 19 mm. 



INIale. — Antennal club very nearly as long as the stem. Abdo- 

 men rather deeply impressed at middle, not hairy, penultimate seg- 

 ment acutely notched at middle, the last segment with a deep trian- 

 gular impression, with rather abrupt sides, the apical margin sinu- 

 ous with two small lobes at middle. 



Variations. — There is such a marked difference in color between 

 two large Texas specimens and some smaller ones from Kansas and
