ORDER COLEOPTERA. 219 



In" others the length of the third articulation of the 

 antennas is triple, or nearly so, of that of the preceding. 

 These organs, as well as the feet, are generally slender. 



In these, the first four articulations of the anterior tarsi of 

 the males are broad, and the penultimate is bilobate. 



CoLPODES, Macl, 



This sub-genus, established by Mr. Macleay (the son), 

 Ann. Jav. I. p. I7, t. i., fig. 3, appears to have great rela- 

 tions with the preceding and the following. According to 

 him the labrum is in a transverse and entire square. The 

 emargination of the mentum is simple, or without tooth. 

 The head is almost of the length of the corslet. This last 

 is almost in the form of a truncated cone, emarginated in 

 front, with the sides rounded, and a litte bordered. The 

 elytra are a little emarginated. The lobes of the penultimate 

 articulation of the anterior tarsi of the male are larger. The 



the C. elegans of Fabricius, ranged with the Elaphri, by M. Weber. He 

 distinguishes them from another neighbouring sub-genus, which he esta- 

 blishes under the name of Pericahis, by its antennae, the second and 

 third articulations of which are almost of equal length, while here the 

 third is the longest ; by the mandibles, which are short, thick, and curved, 

 instead of being advanced, and almost parallel; also, by reason of the 

 palpi, which are short and thick, with the last articulation ovoid, almost 

 truncated, while those of the perlcali are slender and cylindrical. Finally, 

 because here the head is broader than the corslet, which does not take place 

 in catascopus. The eyes, besides, are very prominent and globular in Peri- 

 calus, which gives them some resemblance to Elaphrus and Cicindela. 

 He has described but one species (Pericalus ciciiideluides, 1. 2.); but we 

 are yet ignorant what are the sexual differences, especially in relation to 

 the tarsi. The form of the tongue of catascopus, and that of the legs, 

 remove them from Elaphrus and Tachys. The insects approach much 

 more to the Chlenia, Anchomenus, Sphodms, &c. Many simplicimanous 

 Carabici have the extremity of their elytra strongly sinuated at the end, 

 and in this character are hardly distinguishable from the Truncatijienncs.
