Sericoderus obscurus. — Rufo-piceus, flavo-pubescens, tiiorace lateribus rufis, basi 

 utrinqiie subantjnlato, elytris snbtiliter pimctulatis, apice pedibusque flavis. Long. -025. 

 One specimen, New York. — Smaller than .S'. //((ridits and a little narrower; the thorax is 

 more broadly rounded in the middle, and the posterior angles are more produced, forming 

 ■with the middle of the base a distinct angle ; the elytra are a little more narrowed behind, 

 and seem more distinctly punctured ; the truncated margin is yellowish ; beneath dusky, 

 feet and tip of the abdomen yellowish. 



Sericoderus subtilis. — Flavo-testaceus, flavo-pubescens ; thorace macula antica 

 obsctira uotati). angulis poaticis valde productis ; elytris punctulatis. Long. -02. Illinois, 

 Wilcox. — Smaller and more convex than .S'. jhividiis, with the thorax not so transverse, and 

 the posterior angles much more produced ; the elytra are more narrowed posteriorly and 

 more distinctly punctured ; the pectus is scarcely darker than the abdomen. 



In the Proc. Amer. Philosoph. Soc. xvii. p. 899 (1878), Dr. Le Conte described 

 three species of Orthopems, viz. 0. Scutellaria, (). siUnnilis, and O. eloiii/atus : of these I have 

 only seen 0. scutellaris, but this proved on dissection to belong to Spiiaiiits. The following 

 are his own descriptions of the other two : — 



" Orthoperus suturalis.— Oval, rounded, slightly convex, piceous-black, glabrous, 

 shining, scutellum distmct, elytra with a very fine sutural stria slightly visible "from the 

 middle to the tip. Long. -05 mm. = -02 inch. Enterprize, Florida. — Smaller, or of the 

 same size as 0. i/lahcf, but easily known by the distinct scutellum, and fine sutural stria ; 

 the elytra are very sparsely and indistinctly punctulate, as in the preceding. 



"Orthoperus elongatus. — Oblong, elongate, convex, piceous, moderately shining ; 

 scutellum distinct ; elytra with a very fine sutural stria, effaced behind, but curving in front 

 around the base, and_ ending half-way between the scutellum and the humerus, tips 

 separately rounded ; with the apex of the abdomen more prominent than in the other 

 species. Long. -05 mm. = -02 inch. Tampa, Florida.— Smaller and narrower than the 

 other species, very much the form of a I'tiliuiii." 



[This species is described in the Biol. Centr. Amer. col. ii., part i. p. 105 (1887), as 

 uEnir/iiiaticniH iitilioides, n. s. — Ed.] 



In the Bull. U. S. Geograph. and Geolog. Survey, v. p. 512 (1879), Dr. Le Conte 

 described a new species of Sxeiiwi, which he named .S'. biiiuttatuni : but, since I have not 

 seen any type of this species, I can only quote his original description : — 



" Sacium biguttatum. — Elongate, black, very finely pubescent ; prothorax not 

 wider at the base tliau its length, sides and apex strongly margined, diaphanous in front 

 for nearly one-third of its length ; elytra each with a rounded red spot a little behind the 

 middle and half-way from the suture to the side ; under surface and legs black. Long. 

 1-6 mm. Vita Pass, Colo. — Of the same size as S. tuguhre and S. uhscuniin, but the 

 prothorax is rather longer, and the elytral spot distinguishes it at first sight."

 picatus, p. 80. 

 punctum, p. 80. 

 To attempt to identify a species by the vague remarks which represent descriptions in 

 this work would be perfectly useless. D. CasMoides has nevertheless been retained for the 

 Corylophus which now bears that name, owing to its subsequent adoption by Mr. Stephens. 

 — D. jyicatus and D. punctum are supposed to represent respectively the well-known species 

 of Orthoperus — O. atomus, Gyll., and 0. atomarlus, Heer.
