This elegant and scarce species is at once distinguished by tbe me- 

 dial frontal carina, which is forked just above the clypeus, the two 

 brandies thence continuing parallel to the vertex. The two exterior 

 carinse curve outwardly in the middle, and converge again slightly be- 

 tween the eyes. All the carinse are yellowish-white, bordered with 

 black, the ground colour of the face being testaceous brown. Curtis 

 appears to have founded his genus Griomorphus upon a brachypterous ? , 

 for he says the abdomen behind is conical. 



I have not met with this species, but two brachypterous males are 

 in the collection of Mr. Douglas. I have no knowledge of their locality 

 in this country, nor does Curtis indicate that of his specimen.
