“ Professor Westwood’s descriptions of the two last species were subsequent to 
those of Mr, J. Thomson. 
Aicus cIcaTRIcosus. 
“ This insect, formerly belonging to Count Dejean’s collection, is stated on the 
label to have been received from Java. I cannot but think this to be erroneous. In 
the first place, I have had the opportunity of examining various collections containing 
numerous series of well-known previously-described species from Java belonging to 
the genus Agus, and I have never as yet been able to recognize another specimen of 
the insect alluded to. Secondly, numerous examples of it (now before the Meeting) 
have lately been received, both from Cambudia and Malacca, evidently identical with 
Count Dejean’s species, and found (upon examination with a specimen in the British 
Museum collection notified as received from Mr. M‘Leay) to be likewise identical with 
igus Chelifer, described by that Entomologist in the ‘ Hore Entomologice,’ p. 113, 
and stated to be from Australia. The last-mentioned habitat must also be incorrect, 
in corroboration of which opinion I may further add that Nigidius cornutus, described 
by Mr. M‘Leay (lib. cit.) with the habitat of Australia, has recently been received both 
from Cambodia and Malacca ; examples in the collections of Mr. W. Saunders and 
Count Mniszech being identical with a typical specimen in the British Museum. 
“Mons, Reiche, in his ‘ Critique’ upon Dr. Burmeister’s ‘ Handbuch der Entomo- 
logie’ (vide Ann. Soc. Ent. de Fr. vol. i. ser. 3, p. 82), states Count Dejean’s insect to be 
identical with Dorcus cicatricosus of Wiedemann, from Java. In this I cannot agree, 
as, according to Wiedemann’s description in the ‘ Zoologisches Magazin,’ vol. ii. p- 
108, it is evident that the insect there characterized represents a female, no allusion 
at all being made to the male. Wiedemann’s species is no doubt, as suggested by Dr. 
Burmeister, the female of igus acuminatus, Fab., a species far from uncommon in 
Java. 
“ With all these facts before me, I have but little hesitation in referring Count 
Dejean’s species to Agus Chelifer of M‘Leay with the habitat of Cambodia and M a- 
lacea instead of Australia, and a distinct species from Agus acuminatus of Fabricius.
