88 MANDIBULATA. — COLEOPTERA. 



Subolive-black, elytra scarcely dilated, with a series of remote impressions be- 

 tween the ordinary striee : head obsoletely punctulated, with a small obsolete 

 frontal lunule, and the anterior margin luteous-red : thorax, with the entire 

 margin luteous, the lateral broadly, and the anterior and posterior, the latter 

 especially, narrowly edged ; the disc impunctate, with an abbreviated dorsal 

 line, the base and apex with an interrupted row of impressions, and the lateral 

 margins with a continuous scattered one : elytra oblong, rather convex, with 

 three continuous punctate striae, and a series of remote impressions between 

 each ; towards the apex more or less punctate, the lateral margin luteous : 

 body beneath yellowish or deep ferruginous : the latinise of the sternum very 

 acute : legs testaceous. Female with the elytra smooth. 



Several pairs of this insect have been taken, but the males are 

 usually confounded, in most cabinets, with those of the following 

 species; they may, however, be readily distinguished by their 

 difference in form, and by their colour, both above and beneath.

Oblong-ovate, black or olivaceous : elytra scarcely dilated : head as in the last : 

 thorax also bordered as in it, with the posterior margin very narrow, and 

 frequently obscured with fuscous clouds; the disc with a longitudinal line, 

 and the margins punctured as in the foregoing: scutellum black: elytra 

 oblong-ovate, not dilated, the lateral margins broadly testaceous or flavescent, 

 the disc with three punctate striae, the spaces between obsoletely punctulate 

 towards the apex : body testaceous or yellowish beneath, the sutures of the 

 breast black, the latinise of the sternum very acute : legs testaceous. Female 

 with the upper surface of the thorax, and of the elytra, thickly but finely 

 punctate ; the base of the latter deeply sulcated beyond the middle. 



The female is probably the Dy. dubius of Gyllenhal.
