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 antennas 



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.

Paussus denticornis, Donovan, 1st edit. 

 Habitat. Bengal. 



The first account of the genus Paussus appears in a small tract written by 

 Linnaeus, and published at TJpsal, in the year 1775, under the title of Bigce. 

 Insectorum, &c. This paper contains likewise a description of the Diopsis o-eniis 

 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 adchttonal celebrity also, from the recollects that the dissertation in winch 

 they are ^inserted concluded the Entomological labours of that distinguished 

 naturahst : lt was the last he ever published in the department of zoology ^
