Note.—Add sub-genera Basoleia and Melisodera WESTWOOD, whom see 
in GuérIn Magas. de Zool. 1835, Pl. 132. These coleoptera form the 
transition to the carabict with truncated elytra, with which, according 
to the opinion of some authors, they would be more correctly classed. 
** Elytra truncated at the apex on obtuse. 
Truncatipenes LATR. ; a subdivision scarcely to be defined by certain 
limits, separate from the preceding by negative characters ; compare WEST- 
woop Modern Classification 1. p. 75. Tarsi mostly not different in the 
sexes. Claws of tarsi often denticulate beneath. 
Different species of the typical genus of this division, Brachinus 
(Aptinus Bonet), eject for their defence an acrid fluid from the 
anus, which presently evaporates with an explosion and causes an 
inflammation on the skin. Hence the name of Bombardier-beetle. 
ROLANDER gave the first account of this peculiarity in the Transactions 
of the Academy of Stockholm for 1750. See, on the parts which secrete 
the fluid, Léon Durour, Ann. du Muséum, xviii. 1811, pp. 7o—81, Pl. 5 
(in Aptinus ballista), and especially Ann. des Sc. natur. v1. pp. 6—14.
