the last joint oval, acute. Prothorax wider than lonp:, gradually nar- 

 rowed from the hasc forwards, transversely very convex in front, base 

 bisinuate. Scutolluni rather large, triangular. Elytra convex, not 

 wider than the prothorax, punctures fine, not arranged in rows. The 

 other characters present nothing worthy of record. 



T. Croteliii. — Bhick with a bronze lustre, finely pubescent with short 

 Buberect gray hair, finely and sparsely punctulate. Length .10 inch ; 2.5 mm. 

 A singular insect found by Mr. Crotch, at San Diego. Differs re- 

 markably from Lutrochm, to which it is otherwise allied, by the 

 longer and slender antenna; and elongate form of body. It bears a 

 general resemblance to Throscns, in appearance. 



ELmiS Latr. 

 E. (Iivor$;cns. — P]longate oval, dark green-bronzed, finely pubescent : 

 prothorax one-half wider than long, gradually narrowed and rounded on the 

 aides from the base, disc convex distinctly punctured, basal lines extending as 

 far as the middle, slightly divergent outwards, base emarginate in front of the 

 scutellum, not fovcate; elytra elongate scarcely wider than the prothorax, 

 nearly jtarrllel on the sides and strongly margined, disc convex, striae com- 

 posed of close set quadrate punctures, scarcely finer at the apex, interspaces 

 obsoletely punctulate; tarsi brownish. Length .10 inches; 2.5 mm. 



California; Mr. Crotch. Narrower than E. ovalis, with the sides 

 of the elytra nearly straight; quite distinct from all other species 

 I have seen by the basal lines of the prothorax diverging outwards. 



E. corpiilentus.— Ovate, convex, thinly and finely pubescent, greenish- 

 black ; prothorax somewhat wider than long, feebly channelled, scarcely punc- 

 tulate, narrowed and rounded from the bnse. front angles dellexed and broadly 

 impressed, basal lines extending to the middle, very deeply impressed, not 

 divergent, base emarginate in front of the scutellum, not foveate. Elytra 

 wider than prothorax, very convex behind, much rounded on the sides, strise 

 deep, j)unetured in front, finer and less punctured behind ; interspaces feebly 

 j)unctulate. Length .10 inch ; 2.5 mm. 



British Columbia; Mr. Crotch. In one specimen the elytra 

 have abroad basal band and large apical spot yellow; the antenna) 

 joints 1 — 8 and the legs are also testaceous. 



E. seriatus. — Elongate oval, black with a greenish reflection; prothorax 

 wider than long, distinctly punctured, narrowed, and feebly rounded from the 

 base, basal lines extending to the middle, with a fovea near the anterior ex- 

 tremity of each, base with two small foveae near the seutellar emargination. 

 Elytra scarcely wider than the prothorax, nearly parallel on the sides, not very 

 convex, striae composed of oval rather distant punctures, interspaces obsoletely 

 punctulate; a largo indistinct subhumeral yellowish blotch extends to the 

 sides but not to the suture, last joint of tarsi yellowish. Length .075 inch; 

 1.8 mm.
