278 GEO. H. HORN, M. I). 



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

 domen flattened at middle, posterior half of the penultimate segment 

 obliquely declivous, finely granulate. Last segment flat, slightly 

 granlate. 



Variations. — The larger number of specimens are nearly as cy- 

 lindrical as ephilida, others are slightly oval. The elytral costse vary 

 somewhat in distinctness, but in no specimens is the submarginal 

 fairly developed. 



At the time of the original description Dr. LeConte suspected 

 that this might possibly be a small race of sabmucida. This seems 

 now very unlikely. The clypeus is more concave, the punctures of 

 entire surface coarser ; there is no iridescence, and finally the male 

 characters are sufficiently different. 



I have seen very many of this species at times, but in the two 

 dozen or more now accessible I have not found a female. 



Occurs in Kansas and Texas, probably extending into Mexico. 



65. Li. fucata u. sp. — Oblong, slightly ovate, reddish-brown or pale casta- 

 neous, surface very shining. Head not broad. Clypeus emarginate, slightly 

 concave, the margin narrowly reflcxed, coarsely and moderately closely punctate, 

 front more closely. Thorax distinctly narrowed in front, sides arcuate, margin 

 entire, not ciliate, punctures of disc moderate in size, regularly placed, but not 

 close. Elytral punctures of similar size to those of the thorax, rather more 

 closely placed, but sparser near the apex, sutural costa distinct, discal costfe very 

 feeble, submarginal costa well marked ])osteriorly. Pygidium sparsely but regu- 

 larly punctate, the punctures finer than on the thorax. Metasternum closely 

 punctate, the hair moderately long, but not dense. Abdomen sparsely finely 

 punctate, the penultimate segment more coarsely punctured at the sides. Last 

 joint of maxillary palpi subcylindrical, slightly impressed. Claws arcuate, the 

 tooth moderate in size, slightly intramedian. Length .55 — .65 inch; 14 — 16.5 

 mm. 



Male. — Club of antennse as long as the funiculus. Penultimate 

 ventral segment (fig. 23) slightly flattened posteriorly and with a 

 slight arcuate process projecting over the suture with the last ven- 

 tral, the sides sometimes obliquely plicate. 



Variations. — In some specimens the elytra are slightly wrinkled. 



Of this species I have examined nine specimens, all males. It is 

 remarkable in this part of the genus by its very shining surface. 



Collected in southern Arizona (C. G. Pringle). 



66. li. e.xorata n. sp. — Oblong, slightly oval, facies moderately robust, dark 

 chestnut-brown, surface feebly shining. Head not broad. Clypeus subtriincate, 

 margin moderately reflexed, punctuation coarse and closely placed, frontal suture 

 rather deeply impressed, front more densely punctured, somewhat rugulose. 

 Thorax with sides strongly arcuate in front, parallel behind, margin rather dis-
