Long. corp. 2 lin., lat. 1 lin. 



Ovate, broad, depressed, very finely pubescent, rufo-fuscous. Head 

 short, depressed, hardly produced ; eyes large, prominent, situated at 

 the back of the head : antennae approximate ; above their insertion 

 are two small tubercles, while immediately above these (extending 

 to the base) is a medial longitudinal ridge ; surface punctate, rufous, 

 the medial ridge being rufo-piceous. Thorax transverse (not, as in 

 P. adumbratus, quadrate), slightly constricted in the middle ; the an- 

 terior angles depressed and subacute ; the sides marginate ; siu-face 

 finely punctate, obsoletely pubescent, and rufo-flavous, — the margi- 

 nation, and a medial longitudinal line, being rufo-fuscous. Scutel- 

 lum small, triangular, fuscous. Elytra broader than the thorax, 

 punctate-striate (the stria? being almost obsolete, and the punctures 

 large and deep), indistinctly clothed with ashy pubescence, fuscous, 

 — the base of the elytra (from the humeral angle to the scutellum), 

 a medial, broad, indeterminate fascia (which does not reach the 

 suture), and the apex of the elytra, being rufous. Antennce filiform, 

 robust, flavous, with the fifth and sixth joints rufo-flavous. Legs 

 testaceous throughout. 



This species, in its general facies and in the disposition of its 

 markings, almost entirely resembles P. adumbratus ; it may be, how- 

 ever, without hesitation, separated from it by the medial longitudinal 

 ridge on the head, and by its transverse (not quadrate and con- 

 stricted) thorax.

Long. corp. 2 lin., lat. 1 lin. 



Oblong-ovate, broad, depressed, subpubescent, rufo-ferrugineous. 

 Head short, somewhat produced in front, vertical (slightly reflected 

 backwards) ; eyes large, prominent, black, extending laterally as far 

 as the line of the thorax ; between the eyes, and above the insertion 

 of the antennae, is a minute Y-shaped depression, while above it (ex- 

 tending as far as the base of the bead) is an obsolete medial longitu- 

 dinal carination ; the surface finely punctate, flavo-rufous. Thorax
