Sub-Family OCHOD^IN^, Arr., 

 Trans. Entom. Soc. Lond., 1904, p. 747. 

 Arrow, loc. cit., separates Ocliodmts from the Orphnince, and 

 creates for it a sub-family basing itself on the difference in the 

 position of the stridulating organs, and also on it having a pectinate 

 spine to the middle tibia ; this character is, however, variable, because 

 Chcetocanthus, Per., and Synochodceus, Kolb., have all the spurs 

 crenulate, but as pointed out by Kolbe (Ann. Soc. Ent. Belg., li., 

 1907, p. 27), in the Ochodceince the very globose eyes are not divided 

 in front by the canthus of the genae.

Ochod^us adsequa, Kolbe, 



Ann. Soc. Ent. Belg., vol. li., 1907, p. 28. 



" Ferruginous brown, moderately shiny, briefly flavopilose, more 

 shiny underneath, the margins and legs with longer hairs ; head 

 very closely rugose granulate, epistoma slightly sinuate in the 

 middle of the anterior part, prothorax closely granulate, and having 

 in the centre a longitudinal furrow disappearing in front; elytra 

 short, moderately deeply striate, striae finely punctulate, intervals 

 convex, profusely granulate but less densely than on the prothorax ; 

 anterior tibiee tri-dentate, the two apical teeth large, elongated, 

 third minute ; tibiae of hind and intermediate legs compressed, large, 

 especially the hind ones. 



Length 5f mm.

Gen. CH^TOCANTHUS, Pering., Cat. i., p. 495.* 

 Ch^tocanthus bechuanus, n. sp. 

 Pale testaceous, sometimes slightly redder on the head and 

 prothorax than on the elytra, covered all over the upper surface 

 with a very short, appressed flavescent pubescence, and the long 

 hairs edging the canthus of the eye, the sides of the thorax and 

 of the elytra, the under side and legs, are of the same tint ; head 

 covered with contiguous, sharp granules ; prothorax covered with 

 similar but more elongated granules ; in the centre is a quite plain, 



* In my description of the genus I omitted to indicate that the longer spur of 

 all the tibiae is crenulate.
