MR. A. MURRAY'S MONOGRAPH OF THE FAMILY OF NITIDULARIÆ. 269 
tate curved space, and then another impunctate, slightly raised, curved line, all irregular 
and semiobsolete. Scutellum sparsely punctate. Elytra with rows of rather coarse punc- 
tures and pubescence; in the males wholly black; in the females ferruginous, with the 
margins and apex black. Abdominal segments finely punctate, except at the margins, 
which are smooth. Antennze and legs rufo-piceous. 
Collected by M. Sallé at Toxpam, in Mexico, in the month of July. It is from his 
observation that I am enabled to indicate the sexes. 
This species is scarcely broad enough to come into this section, it is not depressed 
enough for the next section, and it is scarcely narrow enough to fall into the third 
section. On the whole, it comes, on the strength of the ferruginous elytra in the female, 
better here, beside the somewhat convex species which have a red spot on the elytra, than 
anywhere else.
