60 TETRAGON OTES. 



Oblong-ovate, parallel, subdepressed, very finely pubescent, punc- 

 tate-striate, fusco-flavous. Head produced in front ; from the labnim 

 to the base of the antennse longitudinally carinated ; above the base 

 are two oblique carinations, extending to the upper and inner sur- 

 face of the eyes ; eyes tolerably large, extending laterally as far as the 

 anterior angles of the thorax; between the eyes, immediately above 

 the oblique carination, is a transverse depression, most apparent when 

 viewed transversely ; the surface is deeply and closely punctate ; of 

 a dark fuscous colour, the anterior portion of the head and also two 

 subcircular spots at the upper and inner margin of the eyes being 

 fulvous. Thorax elongate, rectilinear, the anterior angles subde- 

 pressed, the sides marginate, with an antemedial angulated projec- 

 tion ; the basal angles are slightly truncate ; when viewed from be- 

 hind, a slight transverse basal depression gives distinctness to two 

 faintly raised antemedial prominences ; finely and sparingly pubes- 

 cent ; the colour testaceous, with a broad longitudinal medial fascia 

 and also the margination on the sides fulvous. Scutellum fuscous. 

 Elytra rather broader than the thorax, parallel, punctate-striate, 

 the striae being obsolete near the apex, clothed sparingly with obso- 

 lete pubescence ; the colour is testaceous, with a broad longitudinal 

 band from the shoulders nearly to the apex fuscous ; the suture also 

 and the lateral margins are narrowly fuscous. Abdomen fuscous, 

 with the apex and three terminal segments testaceous. Antennce 

 somewhat elongate, filiform, piceous. Legs testaceous, the anterior 

 tibiae and tarsi and the apex of the postical femora being suffused 

 with fuscous.

 January 1857 ; also by Mr. Fry and other collectors in the same 

 district.

Oblong-ovate, subparallel, elongate, when viewed under a high
