Louisiana that they would hardly be supposed to be the same species, 

 but the male sexual characters are absolutely identical. A similar 

 variation in color is seen in latlfrons. 



Only males have been observed. 



Occurs in Missouri, Kansas, Texas and Louisiana. 



20. L<. postrema n. sp. — Ohlong, moderately robust, castaneous, shiuing. 

 Clypeus distiuctly eniarginate, the margin moderately reflexed, coarsely punc- 

 tate, closely at middle, more sparsely at the sides, front more coarsely punctate, 

 nearly smooth along the suture. Eyes moderately large. Thorax narrower in 

 front, the sides parallel behind the middle, hardly arcuate in front, the margin 

 entire with very short cilife, punctuation moderate, not closely, but quite regu- 

 larly placed. Elytral punctures coarser and closer than those of the thorax, the 

 postscutellar punctures slightly stellate: sutural costfe distinct, discal costie en- 

 tirely obliterated, the submurginal faintly indicated near the apex. Pygidium 

 broader than long, convex, the punctures coarse, but feebly impressed, placed 

 along the base and sides. Metasternum moderately densely punctured, the hair 

 not long nor dense. Abdomen very indistinctly, sparsely punctate at the sides, 

 the last two segments with a few coarse punctures near the sides. Last joint of 

 maxillary palpi fusiform, depressed, without impression. Claws feebly curved, 

 the tooth strong and median. Length .76 inch ; 19 mm. 



Male. — Antennal club a little longer than the funiculus. Abdo- 

 men slightly flattened at middle, penultimate segment with a trans- 

 verse ridge close to the posterior suture, beneath which the segment 

 is channeled ; last ventral flattened with a few granules. Inner 

 spur of hind tibiae long and slender. 



In this species the emargination of the apex of the hind tibia at 

 the base of the inner spur is less marked than in the other species of 

 the group, although quite evident. Its facies is that of generom or 

 some of the more strongly distinctly punctured forms of fusca. 



One male, Florida. 



21. Li. aflinis Lee. — Obloug. distinctly broader behind, bi-ownish or casta- 

 neous, shining. Clypeus acutely not deeply eniarginate, border narrowly reflexed, 

 surface coar.sely and densely punctate, front more coarsely punctate or even crib- 

 rate at middle. Thorax narrowed in front, the sides behind nearly parallel, in 

 front oblique, the margin serrate, .sparsely ciliate, surface with coarse and deep 

 punctures moderately closely, but somewhat irregularly placed, the median line 

 usually smoother, the basal marginal channel not distinct. Elytral punctures 

 very much finer than those of the thorax, moderately closely placed, distiuctly 

 impressed, the sutural costa distinct, the discal costie very faint or entirely ob- 

 literated, the submarginal extremely indistinct or ab.sent. Pygidium .sparsely 

 punctate, smoother near the apex. Metasternum closely, but indistinctly punc- 

 tate, the hair rather short and sparse 1 , very short 9 . Abdomen sparsely finely 

 punctate, each puncture with a short hair, the last two segments more coarsely 

 punctured. Claws curved, the tooth strong and median. Last joint of maxil- 

 lary palpus fusiform not impressed. Length .65— .78 inch ; 16.5 — 20 mm.
