1. Two eyes. Front margin prolonged into a single 



median toolli Meyathis Steck. 



2. Palps smooth with pointed hairs (4) M. Kochi Sleek. 



2. Palps granular with clavate hairs (5) A/, desiderata Sleek. 



1. Four eyes. Front margin not prolonged into a 



single median tooth CJuhoiiins C. K. 



3. The eyes are well sepai'ated from the front margin, 



Ihis distance heing at least twice their diameter. 

 The distance between them equal to their diameter. 

 The antennae are much sliorter than the céphalo- 

 thorax and scarcely one third as broad. Hand 

 distinctly longer and broader than the tibia of 



the palps. Long pointed hairs (2) C. Wlassicsi Dad. 



;}. The eyes distant from front margin half their 



diameter. 

 4. The antennae are almost as long as the céphalo- 

 thorax, which is as broad as long, and almost 

 half as broad. Tlie front margin is mounted with 

 a dentated minute median eminence. Distance 

 between eyes equals their diameter. Hand di- 

 stinctly broader and much longer than the tibia 



of the palps. Hairs long and pointed (1) C. terribilis n. sp. 



4. The antennae are much shorter than the céphalo- 

 thorax, which is distinctly longer than broad, and 

 much narrower. The front margin without any 

 median eminence. Eyes touching each other. Hand 

 scarcely broader and only slightly longer than the 

 tibia of the palps. Hairs short (3) C. cnrvidigitatiis Sim.

 As all other genera of this family, which have been established, are very 

 doubtful, the characteristics of this genus are in the main identical to those of 

 the subfamily. 



1. Chthonius terribilis n. sp. 



(PI. I, figs, la — 1 m, and lig. 10, p. 70, fig. 11, p. 71.) 



Tivo pair of eyes ; distance from each other as well as from front marqin equal 



to their diameter. Céphalothorax widened out anteriorlij and here broader than long; 



front margin straight with median serrated eminence. Antennae as long as two thirds
