HiSTERIDiE. 
Notes on known species : — 
Perris has published an observation made by Reveliere in Corsica upon the 
habits of lEstcr pustulosvs (Gen(5). This insect feeds upon the caterpillar of 
an Agrotis, which it drags from holes in the ground and kills, although the 
vdctiin is often four times the size of the Hister. Reveliere found that when 
one Hister had captured a caterpillar, others came from various quarters to 
dispute its possession ; he states also that he never met with Hister pustulosusj 
except in ground which exhibited the burrows of the Agrotis-lwcvdi,. (Ann. Soc. 
Ent. Fr. 4® ser. tome iv. p. 304.) 
Baudi considers that Plafgsoma leevicolle ^ algiricttm (Luc.), Berl. 
ent. Zeits. 1804, p. 231, note ; and describes a Piedmontese var. of Hister 
cadaverimts, 1. c. p. 232, note. 
Onthophilus exaratus (Illiger). Waterhouse (Proc. Ent. Soc. Lond. 1864, 
p. 4) has found in his own British collection a specimen of this insect mixed 
with specimens of O. sulcatus, but with no indication of its origin. He calls 
the attention of English entomologists to the characters by which this spe- 
cies is distinguished froni its allies.
