﻿246 LE CONTE— SYNOPSIS OF THE 



dense punctato, lateribus modico rotundatis, elytris subcostatis fortius punctatis, pygidio parce punc- 

 tato, pectore longe villoso, unguiculis dente mediocri armatis. Long. *69. 



One specimen found at Fort Riley by Mr. de Vesey. This species has nearly the 

 form of the common varieties of the preceding, but the punctures of the head, espe- 

 cially towards the side, support short erect hairs ; the punctures of the thorax are 

 stronger than usual in that species, and those of the elytra are not dense but strongly 

 marked. 



The antennae are yellow, and the club of the male is a little longer than the stem ; 

 the abdomen is broadly impressed longitudinally, and the penultimate segment has an 

 obtuse transverse elevation at the middle ; the moveable spur of the posterior tibise is 

 more slender than in L. f u s c a; the tooth of the claws is one-half the length of the 

 apical portion. 



18. L. decidu?, fusco-ferruginea, convexa, oblongo-cylindrica, nitida, capite densius haud confluenter 

 punctato, utrinque pube decidua erecta parce vestito, clypeo baud emarginato, tborace a medio antror- 

 sum angustato, lateribus magis rotundatis longe fimbriatis subserratis, fortius baud dense punctato, 

 elytris subcostatis densius punctatis, longe fimbriatis, pygidio parce punctato, pectore densissime villoso, 

 unguiculis dente mediocri armatis. Long. -6 — -65. 



New York, Mr. Guex. This species and the preceding are nearly related, but the 

 present is more cylindrical in form, with the thorax more rounded on the sides, fringed 

 with long hairs, and narrowed only before the middle : the clypeus is also longer, not 

 emarginate, and more closely punctured ; and the elytra are finely and densely punc- 

 tured. The hairs of the head are sometimes rubbed off, in which case the specimen 

 assumes the appearance very nearly of L. sororia, but may be known by the long hairs 

 of the sides of the thorax and elytra ; the sexual characters are precisely as in the 

 preceding. 



19. L. sororia, elongata, subcylindrica, paulo ovata, fusco-castanea, obsolete pruinosa, capite antice dense 



postice parcius punctato, clypeo latius reflexo vix emarginato, tborace lateribus antice rotundatis parce 

 fortius punctato, elytris fortius minus dense punctatis, subcostatis, pygidio parce punctato, pectore longe 

 flavo-villoso, pedibus castaneis, unguiculis dente longo ( ? ) vel brevi ( & ) armatis. Long. -63. 

 Middle and Southern States, rare : of somewhat the same form asL. fraterna 

 and L. c o g n a t a, but more cylindrical, differing by the less emarginate but more 

 strongly margined clypeus, and by the sparse punctuation of the head. Care must 

 be taken not to confound it with a species (L. rufiola) having 9-jointed antennae, 

 which although resembling it entirely in form and sculpture, differs by the outer spur 

 of the posterior tibiae being less slender, and by the pygidium (of the female) being 

 somewhat conoidal. Body above dark reddish brown, very slightly pruinose, cylin- 

 drical, a little dilated behind. Head moderately punctured, front densely punctured, 

 clypeus with reflexed margin, very slightly emarginate. Thorax not twice as wide 

 as the head, about twice as wide as long, sides not serrate, converging slightly from 

 the base, but only broadly rounded, especially before the middle, surface equably but
