which constitute a normal group, consisting of insects having 

 linear or setaceous antennae, with the exterior biarticulate process 

 of the maxilla palpifomi, and the other three forming an aberrant 

 one, in which the antennae are clavate, or at least gradually 

 thickening towards the apex, while the external lobe of the max- 

 illa is not palpiform. To the former, or normal group, which 

 corresponds with the Jdephaga of Clairville, are assigned, 1. 

 the Geodephagu^ the type of which is Carabus, and 2, the Hydra^ 

 dephaga, having for its type Dytiscus ; while the latter, or aber- 

 rant, comprises, 3. the Philhydrida^ typical example Hydrophilus ; 

 4. Necrophaga, having Silpha for its type ; and 5. Brachelytra, 

 comprehending such insects as would have been included in the 

 genus Staphylinus, Lin. 



The names of the two stirpes of the normal group, Geodephaga 

 and Hydradejjfiaga, at once point out the prominent distinction 

 between them, that the former is terrestrial and the latter aqua-, 

 tic ; a difference of habit which of course implies a variation in 

 the structure of the feet as designed for the respective purposes of 

 walking or of swimming. The five families which compose the 

 former of these, the Geodephaga, are the Cicindelidce, Carabidce, 

 Harpalidce, ScuritidcB, and Brnchinidce. No new form of Ciciti- 

 delidce occurs among the fourteen Javanese species described, all 

 of wliich are referable to the genera Colliuris, Therates, or Cicin- 

 deia. A new subgenus, Lissauchenius, is formed from one of the 

 only two species of Carabidce in the collection, the other being a 

 Panugceus ; but the deficiency in this family is amply compen- 

 sated by the richness of the succeeding one, the Ilarpalidce, no 

 less than twenty-seven species of which are enumerated, compre- 

 hending among them twelve new forms, to which are assigned 

 provisionally the ranks of genera or subgenera according to their 

 appai'ent relative importance. The Scaritidce are only three in 

 number ; and the BrachinidoB amount to ten species, two of which 

 belong io subgenera not previously characterized, although a mere 

 manuscript name had i)een affixed to one of them by the Baron 

 Dejean. 



The Ilydradephaga are not only lejs numerous than the pre- 

 ceding stirps, to which they are connected by the intervention of
