188 Mr, Arthur M. Lea's Bevision of the 



Zaesi/rons, Fairm. — The description of the head of this 

 species is certainly suggestive of a male Hclcogaster, and 

 the elytra are coloured much as in some of the varieties of 

 H. variiis, but the abdomen and appendages are different. 



Atronitens, Fairm. A small variable species, apparently 

 belonging to Hehogaster ; I have seen nothing which I can 

 even doubtfully refer to it. 



Philonthoides, Fairm. — Evidently a dingy species some- 

 what after the style of 2^cdlidipennis, but with the elytra 

 darker and prothorax immaculate at sides. 



The others may be tabulated as follows : — 



A. Elytra armed in the male.* 

 a. Armatura near apex. 



h. Armature knobbed at apex . . blackburnii. Lea. 

 hb. Armature thin and acutely 



pointed eristatifrons, Fairm. 



bbh. Armature wide and obtusely 



pointed pravus, n. sp. 



<(((. Armature near base. 



c. Head bifasciculate in male. 



d. Head of male largely im- 



pressed and without dis- 

 tinct punctures .... fasciadahis, n. sp. 

 dd. Head of male feebly im- 

 pressed and densely and 

 distinctly punctate . . uncinatus, n. sp. 

 cc. Head not fasciculate in male. 



e. Elytral armature pale and 



punctures dense and rather 



small nrmipennis, Fairm. 



ee. Elytral armature dark and 

 punctures sparser and 



much larger fossor, n. sp. 



AA. Elytra unarmed in the male. 



B. Prothorax fasciculate and deeply 

 transversely and longitudinally 



impressed in male rhytideres, Lea. 



BB. Prothorax not as in rhytideres. 



* In the few instances where I do not know the male I assume 

 that the species does not belong to this division ; although quite 

 probably /renc^t does do so, the female] of that species, however, is 

 very distinct. .,.,
