Genera and Species of Coleoptera. 39 
the scutellum; scutellum small, ovate; elytra parallel, rather wider 
than the base of the prothorax, to which they are closely approximate, 
each with five very marked elevated lines, the wide excavated grooves 
between these impunctate, but with a faint trace of another line; body 
beneath dark chestnut; legs reddish chestnut; femora very robust; 
tibize short, subtrigonal, spurred, the anterior very strongly curved ; 
tarsi elongate, the basal larger than the two following, especially the 
intermediate and posterior. Length 33 lines.

Penthelispa Truquit. 
P. fusco-castanea, subnitida; prothorace convexo, fortiter punctato, late- 
ribus antice rotundatis, medio paullo constrictis. 
Hab. Mexico. 
Chestnut-brown, the elytra sometimes with a more reddish tint than 
the rest, subnitid; head coarsely punctured; antenne rather stout, the 
last joint of the club somewhat narrower than the preceding one; pro- 
thorax rather longer than broad, the anterior angles produced, the 
sides rounded anteriorly, but a little constricted in the middle, then 
again slightly rounded and contracting to the base, the disk convex, 
without any central depression, and very coarsely punctured ; scutellum 
transversely rounded; elytra broadest nearly at the base, and very 
slightly rounded at the sides for two-thirds its length, the anterior 
angle not produced, strongly striato-punctate, the punctures shortly 
linear; body beneath dark chestnut-brown, shining, very coarsely 
punctured; legs dark brown. Length 2 lines. 
There is a great similarity between the various species of Penthe- 
lispa*, but the prothorax appears to offer good characters by which 
they may be distinguished. The one described above has that part 
regularly convex, and free from any impression or any elevated line, 
and this separates it from the remainder of the few species yet pub- 
lished. I owe my specimens to my kind friend Mr. Fry, who re- 
ceived it together with a vast number of Coleoptera collected in 
Mexico by the late lamented Signore Truqui, the Italian Minister in 
that country, after whom I have named it. 
Tesapuss [ Cucujide |. 
Caput obcordatum, angulis posticis haud productis, collo brevissimo. 
Antenne moniliformes, articulo primo brevi, tertio paullo longiore. 
* This name was published in October 1860. Dr. Leconte, in his ‘ Classifi- 
cation of the Coleoptera of North America,’ published at Washington “ May 
1861—March 1862,” proposed the term ‘“‘ Endectus” for the North American 
species.
