Pronotum differs In form; elytra not side -margined, only exceptionally 

 ( Dinarda ) the deflected side-margin i s by a sharp ridge separated from the 

 dorsum; they are most often somewhat longer than pronotum. more rarely 

 shorter, scarcely reaching out over the metathorax, covering only the first 

 two dorsal joints of abdomen, either entirely or the second Joint so incom- 

 pletely that its chitinized posterior margin becomes visible. Abdomen is 

 margined, very flexible, and bends when running, or preening or at copula- 

 tion , often upwardly and forwardly. - The fore-coxae are conical and pro- 

 minent, the middle-coxae ovate, contiguous or separated, hind-coxae broad 

 and flat with appressed-*) trochanter; tibiae seldom spiniferous; the num- 

 ber of tarsal Joints differ: either all tarsi are 5-jointed, or all are 

 4-Jointed, or fore-tarsi are 4-Jointed, the others 5-Jointed, or only the 

 hind-tarsi are 5-jointed, the rest 4-jointed.

According to form of head, and the number of ahtennal and tarsal joints, 

 the numerous aleocharinids found in this country can be separated into 

 8 divisions, of which tl.e first three include the majority of jenera and 

 species of the group, the following five only a few species each.
