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.

 and that it is not figured elsewhere. Fabricius refers to Dr. Hunter's Museum, now 

 belonging to the University of Glasgow.
