374 CLASSIFICATION OF THE CARABINE 



Texas; Lieut. Haldeman and Mr. Lindheimer. Except by the form of the antennae, this 

 species almost exactly resembles H. praeusta and laticornis; the thorax is, however, 

 less narrowed posteriorly. 



2. H. t ex an a, piceo-ferruginea, depressa, caput thoraceque valde punctatia, hoc lateribus antice 

 rotundatis, postice angustato et lateribus sinuato, angulis posticis obtusis, elytris tborace latioribus, 

 sulcis minus profundis biseriatim punctatis, interstitiis lsevibus, antennarum articulo 4 to triangulari, 

 eequentibus quadratis vix transversis. Long -7. 



One specimen, Texas; Lieut. Haldeman. By its general form and structure of the an- 

 tenna? this species resembles strongly H. praeusta, but the grooves of the elytra have each 

 two regular series of punctures, while in all our other species the punctures are confused. 



C. Morioncs. 



A group of very difficult location, as it shows very strong resemblance to the Pterosti- 

 chi and Harpali in its external form: from the form of the anterior tibiae, and the antennae, 

 and from the absence of paraglossa?, and the dilatation of the ligula, its true affinities ap- 

 pear to be with the Helluones, from which it differs chiefly in having the elytra as long as 

 the abdomen. In the only species of the group found in our country M. monilicornis, 

 the antennae are less broad and less hairy than in Helluomorpha, the first four joints are 

 shining, with only a few hairs at their extremity ; the following joints are broader, nearly 

 square, glabrous on their flat sides, pubescent near the edges. The anterior tibia; are 

 compressed and dilated, the external angle is slightly produced: the tarsi are short and 

 compressed, those of the male are not dilated. The series of punctures adjacent to the 

 8th stria of the elytra is distinct, and the 9th stria posteriorly diverges from the margin. 



This last character, with the slight posterior constriction of the head, serves well to 

 distinguish this group from any Pterostichi or Harpali to which it may be supposed to be 

 allied. 



Morio pygmaaus Dej. is no Morio. I have formed of it the genus Haplochile, which 

 will be found in group (q.) 



d. Panagai. 



A great innovation is here proposed, by associating the Panaga;i in close relationship 

 with the Anthia). Yet on examination, I have failed to discover any reason for asso- 

 ciating them with Chlcenius, as most authors have done, or with Loricera and Badister 

 as Erichson has proposed. 



The group Licinini of Erichson seems to me so completely artificial that I have dis- 

 carded it. By his definition it differs from Chlceniini only in having the paraglossa? con- 

 nate with the ligula, while in the form and proportions of these same organs we find great 

 differences. By this means we have Badister and Licinus widely separated from Dica?lus, 

 and associated with Pauagoous and Loricera, which seem to have as little affinity with 

 each other as with any of the genera above mentioned. The last genus by its structure 

 and habits belongs to the Elaphri, in the neighbourhood of Blcthisa. 



It would be rash to attempt to fix the characters of the present group definitely without
