DORCtJS. 139 



The bod\' is long and narrow, tlic legs fairly short, the liead 

 and pronotum opaque and almost un])unctured, the elytra 

 very smooth and shining. The h<ad is short, flat, the eyes 

 moderately large, the sides straight and parallel before the 

 eyes and contracted behind them, the front angles blunt. The 

 elypeal process is transversely rectangular, not v(Ty broad, the 

 front margin almost straight. The mandil)les are short, 

 strongly (uirved, each with a strong, short, obli(jue tooth, sharp 

 at the tip, placed near the middle. Tlie profhorfw is much 

 broader than the elytra and has strongly reflexed margins, the 

 sides straight and convergent in front and strongly roundecl 

 behind, without lateral or basal angles, the front angk's pro- 

 duced and blunt. The scutelluvi bears a few fine punctures. 

 The elytra are narrow, very smooth and shining, with very 

 minute punctures, which become closer and more consj)icuous 

 at the sides. The basal margin is rather strongly ])unctured 

 and there is a single row of punctures adjoining the suture and 

 extending from the base to a little beyond the middle. The 

 shoulders are sharply angular. The pro.'iternum is comj>ressed 

 and rather sharply angular behind. The front tihia is finely 

 serrate externally, with two minute but larger teeth and the 

 terminal fork is not long. The middle and hind tibiae are 

 without lateral spines.

The close relationship of this little insect to D. migcli and 

 humilis is evident. It is of almost the same size and shape 

 as the former, but the elytra are still more narrow amd elongate; 

 and extremely glossy, instead of being, like the head and 

 pronotum, dull black. The prothorax is vey short and broad, 

 as in D. nageli, but, together with the head, is scarcely visibly 

 punctured, and the sides are straight and convergent from near 

 the base to the front angles, which are strongly produced but 

 very blunt. The sides of the head in front of the eyes are more 

 straight and parallel than those of nageli and the ch'peal 

 process is rather more prominent, with sharper angles. The 

 mandibles are a little longer, the lobe at the inner edge is more 

 developed, arises rather nearer the base and is produced to a 

 sharp point. The legs and antenn» are more slender than those 

 of the related s])ecies and the middle anfl hinil tibia> are without 

 the strong spine at the outer edge. The prosternum is more 

 elevated and produced behind.
