[Gravenhorstia

This larne and handsome insect is so conspicuous and unlike any other 

 Ophionid that the Rev. T. A. Marshall's diagnoses, translated above, will 

 serve as ample descrijotion. 



He believed his specimens to be new to Science, and points out that 

 the abdomen is shorter and stouter and more pyriform than in other 

 Anomalous, while the black and flavous colours are suggestive of the 

 genus Banchics ; he did not however, remark upon the similarity of its 

 neuration to that of Ophion and was satisfied to leave it in the present 

 Tribe. 



These specimens " were bred by Mr. Mitford from a supposed perma- 

 nent variety of Lasciocainpa tri/o/ii" and were exhibited by Bond " from 

 the cocoons of the supposed variety of L. trifolii, obtained from larvae 

 found at Romney" Marsh in Kent. How many emerged is not known; 

 the type of his name is in Marshall's collection, and there is another 

 female with two males also in the British Museum ; I possess another co- 

 type, kindly given me by Mr. Oliver Janson, who received it direct from 

 Mitford. That these specimens were really indigenous appears extremely
