238 MR. A. MURRAY’S MONOGRAPH OF THE FAMILY OF NITIDULARIZ. 
Searcely half so large as C. pedicularius, more elongate and less convex. Black, 
shining, deeply punctate, with white pubescence. Mouth, antenne, apex of the elytra, 
and legs reddish yellowish-brown. Antenne one-fourth of the body in length, with a 
rather slender club. Head small, forehead flat. Thorax narrowed in front, nearly of the 
breadth of the elytra behind, sloping in a gentle curve to the posterior angles, which are 
obtuse. Scutellum large and rounded. Elytra distinctly and not very closely punctate. 
The colour is variable, which has given rise to the above varieties A and B being 
deseribed as distinct species. 
I am unable to see any سياه‎ between this species and the specimens of Erich- 
son's Brachypterus fulvus preserved in the Berlin Museum. Erichson himself remarks 
regarding the latter that it is very like the reddish varieties of the former, but can be 
distinguished, in addition to the generic characters, by its having the last two segments 
of the abdomen exposed. Now there must be some misapprehension here, because 
Cercus rufilabris likewise has the last two segments exposed.  Erichson, however, 
specially refers, besides, to the generic characters as being those of Brachypterus; but 
as the specimen in the Berlin Museum is unique, and not in a state to allow of these 
characters being observed without sacrificing the specimen, I am inclined to think that 
Erichson must have taken them upon trust; and as it is, in every point that we can test, 
apparently identical with C. rufilabris, I have recorded my opinion that it is synonymous 
with that species. The only difference that I could perceive is that it seemed to be not 
quite so deeply punctate. 
It is found all over the Continent and also in England. 
18. CERCUS SERICANS. 
Leconte, Proc. Acad. Nat. Sci. Philad. Feb. 1859, p. 69 (1859). 
Oblongus, modice convexus, fuscus, punctatus, pube brevi cinerea sericans; capite tho- 
raceque sspe rufo-testaceis, hoc latitudine plus sesquiplo breviore, lateribus rotun- 
datis marginatis; elytris thorace fere duplo longioribus; antennis pedibusque testacels, 
illis articulo nono precedente vix majore. Long. 1 lin., lat. 4 lin. 
Habitat in California, prope Fort Tejon. 
Longer and more slender than the preceding species of the genus, and provided with 
a closer and more silky cinereous short pubescence ; punctate; brown, with the head and 
thorax often rufo-testaceous, and antennz and legs testaceous. The club of the antenna 
biarticulate, the ninth article being scarcely longer than the eighth. Thorax less than 
two-thirds as long as broad. Elytra about twice as long as the thorax. 
Found near Fort Tejon in California. Dr. Leconte has been kind enough to supply 
me with a specimen, which I have placed in the British Museum. 
14. CERCUS EXILIS (Laferté). 
Parvus, subcylindricus, flavus, punctatus, pubescens. Long. $ lin., lat. 1 lin. 
Habitat in Cumana. 
Small, narrow, cylindrical, not unlike a small Carpophilus. Yellow, punctate, and
