This is an extremely distinct species in many characters, especi- 

 ally those of the antennas, mesosternum and posterior tarsi, but it 

 does not differ generically from L. obesus. The species described as 

 varians by Dr. Sharp (Biol. Cent.-Anier. Col., II, i, p. 260), does 

 not appear to differ specifically, and, in accordance with the theory 

 of distribution by ocean currents from Central America to Florida, 

 formerly held by Dr. LeConte (Proc. Am. Phil. Soc, XVII, p. 471), 

 and more recently demonstrated by Mr. Schwarz (Proc. Ent. Soc. 

 Wash., I, p. 145), the proposed synonymy is rendered highly pro- 

 bable. 



L<. tiniformis n. sp. — Somewhat broadly, evenly oval, very strongly 

 convex, pale ochreous-flavate throughout, strongly shining. Head not reticu- 

 late, extremely minutely, obsoletely and sparsely punctate, with a few scattered 

 punctures of larger size near the eyes ; the latter moderate, the inner margin 

 and beaded edge of the epistoma as in princeps; antennae moderate, funicle 

 slender, third joint much shorter tlian the next two combined, fourth sliglitly 

 shorter than the fifth, eighth very slightly shorter than the seventh, a little 

 wider than long, club robust, fusiform, nearly symmetrical, eleventh joint fully 

 as long as the two preceding combined. Prothorax distinctly more than twice 

 as wide as long ; ba.sal lobe very broad and extremely feeble, the bead fine but 

 strong, continuing laterally to within one-fifth the width of the sides, with 

 the posterior margin finely and strongly granulose ; surface polished and 

 almost completely devoid of punctuation. Scutellum equilatero-triangular, 

 the sides feebly arcuate. Elijtra distinctly opalescent, having widely distant 

 rows of moderate punctures, whicli are more deeply impressed and very dis- 

 tinct toward the suture, and more broadly crescentiform but rather more feebly 

 impressed near the sides and apex, obsolete toward base ; intervals with a few 

 widely dispersed, excessively minute punctures ; sutural stria distinct, obsolete 

 at basal third or fourth, the transverse strigilation excessively minute and 

 dense, not resolvable under high power. Abdomen reticulate, sparsely pubes- 

 cent, the rows of robust setae at the apices of the segments especially promi- 

 nent. Legs short and very stout ; obliquity of truncation of the posterior 

 tibiae rather slight, the spurs long and strong, the tarsi rather slender, more 

 symmetrical than in princeps, the basal joint less strongly produced beneath 

 the second, the latter seven or eight times as long as the first on the upper 

 side, and slightly more than twice as long on the lower side, sparsely clothed 

 with very short recumbent seta;, and much longer than the entire remainder. 

 Length 2.4 mm. , 



Texas. 



The metasternal process is very narrow, short, truncate at apex, 

 the mesosternum before it moderately declivous, not at all promi- 

 nent, and not much dilated over the coxae at the sides; prosternal 

 process narrow, very strongly dilated at apex, where it is between
