projection, and the elytra have well-defined shoulders instead of being 

 obliterated as in T. palustris.

Subgen. APOBATRISUS, Raffr., 

 Soc. Ent. d. France, 1896, p. 235. 



This subgenus is distinguished from Trabisas, Raffr., and Proba- 

 trisus, Raffr., by the sensibly narrower smaller head, a little compressed 

 laterally, and having underneath on each side a deep carina edging 

 laterally a depression intended for the reception of the palpi, which 

 are flagellate as in the two above-named subgenera, which character, 

 coupled with the very large abdominal segment having no lateral 

 carina, differentiates them from the true Batrisus, Aube. The value 

 of the prothoracic sulci as a character is not important because they 

 vary ; they are very well defined in Batrisus and Trabisus, which have 

 three, and ixiProbatrisus, which has one only, and disappear almost 

 entirely in Apobatrisus. In one species of the latter there is none ; in 

 another it is replaced by a sulciform fovea. 



This subgenus was established for a species from Gaboon ; but 

 another species has lately been discovered in the Cape Colony. 



Apobatrisus eufus. 



Oblong, rufo-testaceous, entirely covered with rough punctures, and 

 clothed with a brief but dense fulvous pubescence. Head narrower 

 than the prothorax, attenuated in front, with the frontal part sulcate 

 transversely, retuse behind, and having between the eyes two fovea? 

 more distant from one another than from the eyes ; antenna? short, 

 robust, joints third to eighth inclusive decreasing in length, eighth 

 nearly transverse, ninth and tenth larger than the others and trans- 

 verse, eleventh ovate, acuminate at tip ; prothorax nearly triangular 

 and broadest near the anterior angles, slightly transverse, lateral 

 fovea? placed at a great distance from the outer side, transverse sulcus 

 hardly well defined, median fovea smaller than the others, disk with a 

 sulciform fovea, base bifoveate ; elytra broader than the prothorax, 

 and longer than broad, outer sides slightly rounded, shoulders raised,
