COLEOPTERA. 301 



thorax in the form of an elongated heart. Some of them resemble 

 Scaritides and others Lebiae. 



Cephalotes, Bon. Broscus, Panz. 



Length of the antennae almost equal to half that of the body; 

 their joints short, the first shorter than the two following ones taken 

 together; the right mandible strongly unidentated on the internal 

 side; labrum entire(l). 



Stomis, Clairv. 



The antennae longer than the half of the body, and composed of 

 elongated joints, the first of which is longer than the two following 

 ones taken together; the middle of the internal side of the right 

 mandible deeply notched; the labrum emarginate(2). The following 

 subgenus 



Catascopus, Kirby, 



Is distinguished from the two preceding subgenera, to which it 

 otherwise approximates in the relative length of the third joint of 

 the antennae, by the flatness of the body, by being proportionably 

 wider, with a shorter thorax, by the elytra being strongly emarginate 

 laterally at their posterior extremity, and by the elongation of the 

 labrum. The eyes are large and protuberant. These are ornamented 

 with brilliant colours, and at the first glance resemble Cicindelae or 

 Elaphri(3).

(3) This subgenus was established by M. Kirby on one of the Carabici {Catas- 

 copus Hardwickii, Trans. Lin. Soc. XIV, iii, 1; Hist. Nat. des Coleop. d'Eur. II, 

 vii, 8) of the East Indies, which has a green head and thorax, the elytra of a 

 greenish-blue with punctuated striae, and the under part of the body almost 

 blackish. M. Mac Leay, Jun. Annul. Javan. I, p. 14 places the Catascopi in 

 his family of the Harpalides, directly after the Chlaenii, and refers to it the C. 

 elegans, Fab., which M. Weber arranges with the Elaphri. He distinguishes them 

 from another neighbouring subgenus, which he establishes under the name of 

 Pericalus, by the antennae, the second and third joints of which are nearly equal 

 in length, whilst here the third is the longest; by the mandibles which are short, 

 thick, and curved, instead of being directed forwards and nearly parallel; by the 

 palpi which are short, thick, with the last joint ovoid and almost truncated, whilst 

 those of the Pericali are slender and cylindrical; and finally by the head, which is 

 wider than the thorax, a circumstance that does not occur in the Catascopi. Be- 

 sides this, the eyes of the Pericali are very globular and protuberant, giving them 

 some resemblance to the Elaphri and Cicindelae. He describes but one species
