Ors. In Bn. Dejean's catalogue we find a manuscript-name " longicollis" assigned without any 

 description by Megerle to an Indian Drypta. As I conceive this entomologist may only have 

 obtained a knowledge of such Indian insects as were collected by M. Fichtel, I account his 

 D. longicollis, although the name will equally apply to the above Javanese insect, to be a native 

 of the Continent. Drypta longicollis differs in that case from D. unidentata, in being atro- 

 cyaneous with yellow femora, in having truncated but not dentated elytra, and in having the 

 fourth joint of the antennae altogether rufous. Drypta flavipes of Wiedemann, a Bengal insect, 

 seems to be still another distinct species.

Obs. Bonelli has separated the genus Brachinus from Aptinus, on no other account than that 

 the latter is apterous. If, however, we reckon B- sclopeta Fab. to be the type of one genus, and 

 B. ballisla, 111. of the other, the insect above described, although winged, will come nearer to 

 the latter than to the former. The fact is, that Aptinus has not yet been properly separated 

 from Brachinus. 



M. Dejean appears to be acquainted with other Javanese species of the genus than the one 

 mentioned above.
