L,KPTOI.INrS Kraatz. 



^laxillary palpi with third joint tumid, obcoaical, last joint very 

 small, acicular ; front tarsi broadly dilated. 

 Dull brownish black; head densely aciculate, prothorax densely punctured 



with smooth narrow dorsal space; antennae, legs and elytra red, the latter 



dusky near the soutellum 1. riibripeniiis n. sp. 



Very small, testaceous, shining, head and prothorax very sparsely punctured 



towards the sides; elytra sparsely punctured .....2. pusio n. sp. 



1. li. I'ubripeniiis. — Brownish black, nearly opaque, thinly clothed with 

 short brown pubescence. Head twice as long as wide, sides parallel, hind 

 angles and base rounded, above and beneath slightly convex, densely not 

 coarsely aciculate, without smooth frontal line, or other sculpture; antennse 

 rufous, extending half the length of the prothorax, gradually but not strongly 

 tliickened externally, outer joints nearly twice as wide as long. Prothorax 

 not longer, but a little narrower than the head, rather densely punctured, with 

 a narrow smooth dorsal stripe. Elytra densely more finely punctured, dull 

 red, blackish about the scutel, sutural stria well marked. Abdomen above and 

 beneath very finely and densely punctulate, tip yellowish red; hind margins 

 of ventral segments and legs of the same color. Length 6.2 mm. 

 '^. — Last ventral acutely incised and longitudinally impressed. 

 Middle and Western States. Mr. Fauvel has named it for his 

 correspondents L. ruhrlpennis. 



2. li. pusio.— Very small, slender, pale yellow, shining. Head rather 

 convex, nearly twice as long as its width, smooth with a few small scattered 

 punctures each side; sides nearly parallel, base truncate, hind angles narrowly 

 rounded; under surface very sparsely punctured. Prothorax not longer nor 

 narrower than the head, with a few scattered punctures each side. Elytra 

 sparsely finely punctured, sutural stria very fine. Abdomen sparsely punc- 

 tured and pubescent. Length less tlian 2 mm. 



Columbia, S. C. ; Dr. Zimraermann; one specimen. The palpi, 

 antennae and front tarsi are just as in the preceding species ; but I 

 urn uncertain if the middle coxae are separate or contiguous. The 

 small size and great age of the specimen prevent me from endeavoring 

 to remount it. It is the smallest species of the tribe known to me. 



XAXTHOI.IXUS.

B, — Upper marginal line of prothorax separate from the lower one, and not 

 deflexed in front. 



Dorsal series of 4 — 6 punctures; color dark 2. 



Dorsal seiies of 5 — 6 punctures color ])ale ;!.
