8 MANDIBULATA. — COLEOPTERA. 



base, near the suture is a single obscure stria ; legs pitchy-brown, with the 

 tarsi paler : palpi and antennas rufo-testaceous, the latter with the basal joint 

 large, and the club very broad and distinct, the terminal joint obtuse. 

 The great bulk and convexity of the thorax of this species, with its acuminated 

 elytra and broad clava of the antenna?, well distinguish it from its congeners. 



I have seen one specimen only of this species, which was found 

 in moss, " from near Humby in Lincolnshire, in December last." —

Genus CXX. — Catops, Paykul. 



Palpi, maxillary with the last joint subulate, conic ; labial with the last joint 

 obtuse: antennae straight, clavate, not longer than the thorax, the club five- 

 jointed : thorax with the hinder angles acute: elytra more or less striated ; 

 anterior femora in the males generally somewhat incrassated towards the 

 apex ; the intermediate tarsi with the basal joint dilated. 



Catops is known from Ptomaphagus by the greater width of 

 its body, the more or less evidently striated elytra, and other less 

 visible characters; and from Choleva by the abbreviated, more in- 

 crassated, antennae, acute posterior angles of the thorax, &c. 



A. Thorax with the hinder margin cut out near the angles. 



Sp. 1. fornicatus. Oblongo-ovalis niger, antennisthorace longioribus, pedibusque 



ferrugineis. (Long. corp. 2^ lin.) 

 De. fornicatus. De Geer? — Ca. fornicatus. Steph. Catal. 73. No. 783. 



Oblong-oval, black, clothed with a griseo-fulvescent down: palpi ferruginous: 

 antennae ferruginous, with the apex sometimes brownish, subclavate, rather 

 longer than the thorax, the eighth joint rather shorter and narrower than the 

 adjoining, the terminal more robust than the rest, globose-ovate, with the apex 

 obtusely mucronate : thorax transversely quadrate, the hinder margin a little 

 dilated in the middle, and distinctly cut out near the angles on each side: 

 elytra obsoletely striated, the striae running from the base to the apex : legs 

 pitchy-ferruginous. 



Var. /3. Steph. Catal. I. c— Of a pitchy-brown, with the labrum, antennae, and 

 legs ferruginous. 



Var. y. Yellow-luteous, with the head rather obscure. 



Body more oblong than in the rest of the genus. 



The most abundant species of the genus near London ; and not 

 uncommon in other parts of the country. " Bottisham, several 

 specimens extracted from a decayed cheese." — Rev. L. Jenyns.
