COLEOPTERA. 
17 
Elytra scarcely more elongate than in obtectus , but narrowed beyond 
the middle and circularly rounded at the apex as in dominicanus; the su¬ 
tural angle is very obtusely, but evidently, rounded; the striae are sub¬ 
approximate, in pairs, as in the former. They are covered with a yellowish 
fulvous pile, not tessellated. 
Pygidium as in obtectus , less strongly rugulose, more oblique, but not 
subhorizontal as in dominicanus , which has it much longer and not bent 
at the apex. 
Pectus a little darker than the remaining parts of the insect, which are 
rufous as in dominicanus , of which the pectus is also rufous. 
Legs entirely rufous, as in the latter, with no appearance of the dark 
colouring of the posterior thighs observable in obtectus. 
Obs. — Br. centralism Sch. (t. v. p. 1, pag. 92), nearly approaches 
this species, but from the description it is a distinct species : I know about 
a dozen species analogous to these, one of which I regard as a variety 
of centralis. 
Genus PACHYMERUS, Latr. (Grex 2, Sch.). 
Stirps I. Antennae breviusculae, extrorsum crassitudine crescentibus, 
articulis subperfoliatis.— Sch. t. v. p. 1, pag. 114. 1 
Pachymerus qitadrldens, Jehel. 
Breviter ovatus, postice subquadrato-truncatus; piceo-rufescens , supra 
pedibusque tomento umbrino , subtus , thoracis medio basi, scutello , 
elytrorum litura transversa laterali versus medium guttulisque non- 
nullis posterioribus (interdum obsoletis) pygidio pedumque fasciis 
albo-Jlavescente tomentosis; thorace conico , medio longitudinaliter 
elevato canaliculatoque , utrinque ante basin tuberculato ; scutello sub- 
quadrato; elytris basi tuberculo humerisque parum elevatis instructis ; 
pygidio perpendiculare; femoribus posticis eras sis, ante apicem dente 
mediocri tribusque minoribus adjectis , instructis. 
1 The Stirps II. (of which I know no Schonherrian species) must, 
from the character of its antennae, form a peculiar genus.
