as to divide the eyes into two portions. Coxce more approximated. 

 Metasternum triangular in front. Epipleicrcs unusually broad. 



1715. P. peregrinus, w-s- Convex, elongate-oblong, parallel, 

 clothed with longish upright, yellow hairs ; sub-opaque, fusco- 

 piceous, legs and antennee dark-red. 



Head short, truncate in front, widened backwards, with two 

 moderate frontal depressions, antennal orbits a little elevated ; its 

 front part punctate, the occiput granulated. Antennce stout, pilose, 

 1 1 -articulate, the club distinctly two-jointed ; their basal joint barely 

 visible from above, second longer than third ; joints 4-9 transverse, 

 tenth joint shorter than, but nearly twice the breadth of, the eleventh. 

 Prothorax oblong, sides a little curved, sub-crenate, thickly mar- 

 ginated ; apex truncate, but with prominent anterior angles ; base bi- 

 sinuate, posterior angles rectangular ; its surface closely granulated 

 in front and near the sides, somewhat rugose and longitudinally im- 

 pressed on the middle ; each side with a deep channel, expanded 

 near the hind angle, and from thence abruptly bent and extending 

 inwards along the base as a deep narrow groove ; just at the centre 

 of the basal margin there is a fovea ; when viewed sideways the 

 basal margin will be seen to be on a lower plane than the part just 

 before it. Scutellum small. Elytra with sub-crenate margins, 

 striate-punctate, the punctures square, the interstices punctate, and, 

 when looked at from behind, appearing quite rugose ; shoulders 

 rectangular, base much incurved at the middle. Legs stout, the 

 external apex of the tibiae angularly produced, bi-spinose at inner 

 apex ; tarsi with three equal basal joints, which, taken together, are 

 as long as the terminal ; claws distinct. Underside closely and 

 rugosely punctured, bearing short golden hairs. 



This highly-interesting insect presents an appearance quite foreign 

 to the more orthodox Pyowmeridcs.

1716. C. semirufa, n.s. Sub-ovate, convex, shining, spar- 

 ingly covered with fine greyish hairs ; head, thorax, and basal half 

 of elytra red, the last palest, posterior half of these last blackish ; 

 legs and antennae pale-fuscous, the two basal joints of the latter and 

 the tarsi testaceous. 



Head with a few rather large punctures ; eyes large and 

 prominent. Antennce pubescent, their two basal articulations stout, 

 3-8 slender ; the eightli much shorter than seventh, oviform ; the 

 three terminal nearly equal, large, oval. Prothorax with moderately 

 coarse, distant punctures, transversely depressed behind the middle 

 in front of the base wnth two fine caringe, and behind these very 

 finely strigose ; its length and breadth about the same. Scutellum 

 curvilinearly triangular, bipunctate. Elytra much larger than 

 thorax, marginated, widest at the middle, shoulders somewhat
