114 MANDIBULATA. — COLEOPTERA. 



Oblong, black ; head punctulate, with the mouth and labium rufo-ferruginous ; 

 eyes black : thorax rather broad, truncate in front, somewhat more narrow 

 anteriorly tban at the base, which is truncate, with the angles nearly straight, 

 the disc moderately convex anteriorly, with an obsolete rudiment of a longi- 

 tudinal groove, and towards the base a deep transverse broad fovea : elytra an- 

 teriorly rather broader than the base of the thorax, with the shoulders slightly 

 rounded, the sides a little dilated towards the middle, and the apex rounded; 

 the disc moderately convex, punctate-striate, the punctures small and rather 

 distant : legs and antennae ferruginous. 



Differs from the last by its deeper hue, the brevity of its thorax, which is slightly 

 narrowed anteriorly, and by the faint stria? on the elytra. 



Found, though rarely, within the metropolitan district. 



Sp. 9. testaceus. Plate xviii. f. 3. — Brevis, subconvexus, testaceus, thorace 

 lato, antice bisinuato, postice transverslm impresso, elytris tenue punctata 

 striatis. (Long. corp. § lin.) 



Lat. testaceus. — Waterhouse MSS. 



Short, subconvex, testaceous, slightly glossy : head small, with a slight frontal 

 impression : eyes black : thorax very short, broad ; the anterior margin bi- 

 sinuated, the sides considerably dilated in the middle, the disc slightly convex, 

 with an obsolete longitudinal interrupted channel, and towards the base a deep 

 somewhat trilobed transverse fovea, elytra rather broader at the base than that 

 of the thorax, with the shoulders rounded, the lateral margin a little expanded, 

 the apex slightly acute ; the disc somewhat convex, and rather obsoletely 

 punctate-striate: antennae and legs pale testaceous. 



The broad subcordate thorax of this species, the faintly punctate striae on the 

 elytra, and its pale testaceous hue, sufficiently distinguish it from its congeners. 



Taken near London. " Old Brompton, in May." — Mr. G.

Co. ruficollis. Marsham. — Lat. ruficollis. Steph. Catal. 94. No. 1004. 



Elongate, pale testaceous, shining, glabrous; eyes black: thorax oblong, tri-

 slightly prominent, the sides at the base towards the middle expanded ; the 

 apex slightly acuminated ; the disc moderately convex, regularly and deeply 

 punctate-striated, with the alternate interstices somewhat elevated : antennae 

 and legs pale testaceous.
