COLEOPTERA. 
Brachinus : with the head yellow ; the crown dark coloured ; the thorax dark, with 
two large yellow spots ; the elytra black, with a humeral spot ; a broad central 
fascia, interrupted in the middle, and the tips ; as well as the antennae and legs, 
yellowish. Length 7 to 8 lines.

I have not cited Fabricius, nor the other old authorities, as it is evident from 
their descriptions that they confound several distinct, but nearly allied, species together. 
Donovan’s figure agrees, however, with Dejean’s Brachinus bimaculatus, which is from 
the East Indies. 
PLATYRHOPALUS DENTICORNIS.

Paussus denticornis, Donovan, 1st edit. 
Habitat. Bengal. 
The first account of the genus Paussus appears in a small tract written by Lin- 
naeus, and published at Upsal, in the year 1775, under the title of Bigce Insectorum, 
&c. This paper contains likewise a description of the Diopsis genus, which, together 
with the Paussus, are unquestionably two of the most singular genera of the many 
tribes of insects hitherto discovered. Both may possibly derive some additional 
celebrity also, from the recollection that the dissertation in which they are inserted, 
concluded the Entomological labours of that distinguished naturalist : it was the last 
he ever published in the department of zoology.
