Dr. Sharp has made out this species from specimens of 

 both sexes found by himself at Dumfries on Vicia cracca 

 in July last, and records its prior capture by Mr. Lennon in 

 flood refuse at the same place early last spring, and the 

 existence of an example in Mr. Crotch's collection, taken by 

 Mr. Wollaston at Killarney. Subsequently, Mr. Bold re- 

 cords it from Vicia cracca, in the neighbourhood of Nevv- 

 castle-on-Tyne, and about Lanercost, in East Cumberland. 



It is a large insect, of the group in which the rostrum is 

 subulate, allied to craccce and suhulatum, from the former of 

 which it may be known by its larger size, more bulky limbs, 

 and darker antennae, of vVhich the two basal joints only in 

 both sexes (sometimes only the first joint, and that not 

 entirely) are obscurely ferruginous. In both sexes, also, the 

 rostrum is longer in front of the insertion of the antennae, 

 and more gradually acuminate. 



From suhulatum it differs especially in its larger size and 

 the shorter and stouter basal joint of its antennae, and by the 

 rostrum in the female being shorter, thicker, and less pointed ; 

 and in the male more inflated at the base and more evidently 

 acuminated at the apex. 



I am at a loss to account for Wencker's statement that the 

 head is wider in suhulatum than in cerdo.
