302 INSECTA. 



There, the length of the third joint of the antennae is triple, or 

 nearly so, of that of the preceding one. These organs, as well as 

 the legs, are generally slender. 



In these, the four first joints of the anterior tarsi of the males are 

 wide, and the penultimate is bilobate. 



Colpodes, Mac Leay. 



This subgenus established by M. Mac Leay, Jun. Annul. Javan., 

 I, p. 17, pi. i, f. 3 appears to be allied in many points to Catasco- 

 pus and the following subgenera. According to him, the labrum is 

 a transverse square, and entire, the emargination of the mentum 

 simple or edentate, and the head almost the length of the thorax. 

 The latter is nearly in the form of a truncated cone, emarginate 

 before, with rounded and slightly bordered sides. The elytra are 

 slightly emarginate. The lobes of the penultimate joint of the an- 

 terior tarsi of the male are the largest. The body is somewhat con- 

 vex. He quotes but a single species, the brunneus. 



In those, all the joints of the tarsi, in both sexes, are entire. 



Mormolyce, Hagemb. 



The body strongly flattened, foliaceous, and its anterior half much 

 the narrowest; head very long, narrow, and almost cylindrical; tho- 

 rax oval and truncated at both ends; elytra greatly dilated, and. arcu- 

 ated exteriorly, their internal side, near the extremity, profoundly 

 emarginate. 



The only species known phyllodes is found in Java, and 

 forms the subject of a Monograph published by M. Hagem- 

 bach. 



Sphodrus, Clair. Bon. Lcemosthenus, Bon. Carabus, Lin. 



The body depressed but not foliaceous; head ovoid; thorax cordi- 

 form; elytra without any exterior dilatation or internal emargina- 

 tion. 



Several of these Insects live in cellars(l). 



Pericalus cicindeloides, 1, 2; we are still, however, ignorant of their sexual 

 difference, particularly as respects the tarsi. The form of the ligula of the Catas- 

 copi and that of their tibiae remove them from Elaphrus and Tachys. These in- 

 sects approximate most nearly to the Chlxnii, Anchomeni, Sphodri, &c. Several 

 of the Simplicimani have the extremity of their elytra strongly sinuous, and in this 

 respect are hardly distinguished from the Truncatipennes.

 XI, 4. In the Sphodrus terricola Carabus terricola, Payk.; Oliv., Col. Ill, XXXV, 

 ii, 124 the hooks of the tarsi present some small dentations, as in the following 

 subgenus.
