This also is one of the uncharacterized insects which came over 

 to this country in Major Sale's cabinet. It was unique in the col- 

 lection. Those observers of Nature, who take a pleasure in tracing 

 the gradation of the affinities which connect her conterminous 

 groups, will meet an. interesting subject of contemplation in the 

 insect before us. It immediately connects the two adjoining 

 genera of Necrophorus, Fab. and Neerodes ; having the general 

 form, and the antennce of the latter group, with the elytra of the 

 former. The most important of its generick characters bring it 

 within the circle of Neerodes, while in the distribution of its 

 colours, as well as in the brevity of the elytra and the mode in 

 which they are truncated, it assumes the appearance of Necro- 

 phorus. I have named it in conformity with its osculant situation 

 between the two genera.

A single specimen of this insect was found in the same collec- 

 tion as the two preceding species. It is particularly remarkable 

 for the brilliancy of the head and thorax, which assume a fiery 

 appearance, contrasted with the dull black of the elytra.
