A single specimen of this insect, brought from China, and in the possession of Mr. 

 Francillon, was employed as the original of this figure. From the form of the head it 

 ■appears to belong to Serville's sub-genus, Mesops, but the wings extend beyond the body.

belonging to the University of Glasgow.
