COLEOPTERA. 293 



angtes very obtuse or rounded; mandibles destitute of teeth; tooth 

 of the emargination of the mentum widely truncated(l). 



Daptus, Fisch. Acinopus, Dej. 



The antennae, from the fifth joint, moniliform; thorax suddenly 

 narrowed towards its posterior angles, which terminate in a point; 

 one of the mandibles projecting and very pointed; the four anterior 

 tibiae, those of the males particularly, covered with very small 

 spines(2). 



Near Daptus should apparently be placed the genus Pangns of 

 M. Megerle, mentioned by count Dejean in his catalogue. 



In examining one of the two species (the pensylvanicus), referred 

 by the latter to this genus, I could discover no character which 

 should distinguish the section in question from the preceding one. 



The second division consists of Harpali, in which the emargina- 

 tion of the ventum is also unidentate, but where the more or less oval 

 or ovoid body is narrowed before, and the labrum entire, or simply 

 somewhat concave. They form the 



Harpalus, Dej. 



Or the true Harpali. One of the most common in all Europe is 

 H. eeneus; Carabus seneus, Fab.; Panz. Faun. Insect. Germ. 

 LXXV, 3, 4. Body about four lines in length, and of a shining 

 black; antennae and legs fulvous; thorax and elytra most common- 

 ly green, or cupreous and brilliant, sometimes of a bluish black. 

 The thorax is transversal, narrowed posteriorly, and the lateral 

 and posterior margins delicately reflected, with a punctated de- 

 pression on each side near the posterior angles. The elytra are 

 striated, with an incisure near the extremity, and little depress- 

 ed puncta between the exterior striae. This insect has also been 

 called the Proteus, on account of the variety of its colours.(S) 



The total absence of a tooth in the emargination of the mentum

 the Faun. Aust. of Duftschmid. Fabricius has described but few of them, of 

 which we will mention those he calls caliginosus, ruficornis, binotatus, tardus, 

 heros, analis, jlavilabris, &c. The Carabus signatus, and hirtipes of Panzer also 

 constitute a part of this subgenus.
