somewhat X. peltatus, but is very much larger, and rather stouter, and 

 the head is more excavated beneath.

A single specimen collected at Cape San Lucas, Lower California, by Mr. 

 Xantus. The antennae (male) are but little shorter than the body, the joints 

 are broad and triangular, the second being scarcely smaller than the third ; 

 the eyes are very large and prominent. This species resembles X. pellatus 

 more than the preceding, but diifcrs from both by the punctured aud scarcely 

 impressed striae of the elytra. 



LASIODERMA Stephens, Illust. 5, 417. 



Syn. Pseudochina, subg. Hypora Muls. $ Rey, Col. Fr. Te're'diles, 294. 

 The metasternum is declivous in front, with the declivous portion sharply 

 defined by a transverse elevated line, extending entirely across the trunk.

Carried by commerce oyer the whole globe ; lives chiefly, though not ex- 

 clusively, upon tobacco ; I have found it, also, in the powder of capsicum. 



Mr. Chevrolat, (Ann. Ent. Soc. Fr., 1861, 390,) refers this species to Cato- 

 rama,but subsequently has corrected the error ; he considers Pi. testaceus 

 Duftschm., as a different species. Xyletinus pallidas Lap., Hist. Nat., iv. 295, 

 is also cited by him as a synonym, but I have had no opportunity of verifying 

 it; I accept it with hesitation, as Plilinus pallcns Germ., Ins. Nov. 79, a spe- 

 cies with striate elytra, is also quoted under the same name (pallidus.) 



2. L. dermestinum, elongato-ovale, convexum, nigro-piceum, subti- 

 liter griseo-sericeo pubescens, subtilissime alutaceum, thorace latitudine baud 

 breviore, antrorsum subangustato, apice valde rotundato, basi truncato, an- 

 gulis anticis valde deflexis rectis, posticis obtusis subrotundatis, elytris tho-

Cape San Lucas ; collected by Mr. Xantus, and given me by Mr. H. Ulke. 

 In the two specimens before me, I can merely see that the antennae are reddish 

 yellow, without distinguishing particularly the relation of the joints to each 

 other. This species resembles in form a small A 1 1 agen u s, and is much 

 less stout than L. serricorne. 



7CATORAMA Gue>. 



The species which I have referred to this genus differs from C. t a b a c i, the 

 type described by Gucrin (Rev. et Mag. Zool. 1850, 431.) by the last joint of the 

 palpi being truncate, but not emarginate. There is, however, not a complete uni- 

 formity in the different species of Xyletinus in this respect, and I have, there-
