The only species at present known is the following : 



23. li. calceata Lee. — Oblong oval, broader beliind, subdefiressed, castane- 

 ous, shining. Clypeus emarginate, more deeply iu the female, margin rather 

 widely reflexed, surface closely punctate, front flat, more densely punctate, espe- 

 cially at middle. Thorax widest at middle, slightly narrowed in front, margin 

 more or less serrate, sparsely ciliate, punctures coarse and rather close, denser 

 and finer along the apex, a moderately wide median smooth space and a smaller 

 smooth spot on each side in front of middle, a feeble depression of the basal mar- 

 gin each side. Elytral punctures very much finer and closer than those of the 

 thorax, smoother at apex, sutural costa convex, the first dorsal well developed, 

 broader and more convex posteriorly where it adjoins the sutural, the other dor- 

 sal costfe not distinct, submarginal distinct and long. Pygidium sparsely punc- 

 tate, smoother near the apex. Metasternum densely punctured, the hair long 

 and dense, shorter in 9 • Abdomen moderately coarsely and closely punctate, 

 the last two segments more coarsely. Claws arcuate, the tooth median and 

 .strong, longer) in the female. Last joint of maxillary palpi fusiform, flattened 

 externally. Length .75 — .80 inch ; 19 — 20 mm. 



Male. — Antennal club a little longer than the stem. Abdomen 

 broadly concave at middle, penultimate (fig. 87) segment concave 

 posteriorly, the concavity limited each side by an oblique moderately 

 elevated process which projects slightly over the concavity. Last 

 ventral with a reniform depression. Posterior femur (fig. 15) ob- 

 tusely subangulate at middle. Inner spur of hind tibia broad and 

 squarely truncate, the outer longer, although broad, acute. First 

 joint of hind tarsus (fig. 15) short, the distal extremity abruptly 

 produced on the outer side. Pygidium convex, broad. 



Female. — Antennal club shorter than the funiculus. Posterior 

 femora stout, of the usual form. Spurs of hind tibijB rather broad. 

 Posterior tarsi shorter than the male, the first joint similar, but with 

 the process less marked. Pygidium more elongate than in the male, 

 the punctuation more regular and distinct. 



Variations. — In the comparatively large number of si)ecimens 

 examined no special variation has been observed. The color does 

 not vary to any extent. 



This species has some superficial resemblance to rugosa, etc., but 

 the elytra have the smoother sculpture of fiisca. 



Occurs in Texas. 



Group IX, fusca. 



After having separated all those species possessing well marked 



structural characters there remain a large number of species of 



analogous form and structure which constitute this central group of 



the genus. Many of the species are of common occurrence and
