CURCULIONIDJE.- — LIXUS. 157 



Genus CCCXXXVL— Lixus, Fahricius. 



Antenna geniculated, 12-jointe(l, rather short, deflexed, slender, inserted behind 

 the middle of the rostrum; funiculus with the two basal joints elongate, ob- 

 conic; the four following short, truncate at the apex; the next stouter, 

 closely appUed to the club, which is oblong, fusiform. Rostrum elongate, 

 moderately robust, rounded or cylindric, nearly straight, or very little curved: 

 thorax oblong, conic, a little coarctate on the sides anteriorly, the base bi- 

 sinuated : elytra oblong, cylindric, sometimes attenuated and gaping at the 

 apex: legs long, slender: femora cylindric, unarmed: tibia with a hook 

 within at the apex. 



From the foregoing genera, of this group of the Cureulionidse, 

 the present may be known by the greater length and tenuity of the 

 rostrum, and by having the antennae placed towards the base thereof; 

 the body elongate, pubescent, and not varied :— the larvffi are de- 

 structive to the roots of plants. 



A. With the elytra acuminated at the apex. 

 J Sp. 1. Ascanii. Cylindricus ater, Jlavescenti-pollinosus, thoracis elytrorumque 



marginibus ccerulescenti-albidis. (Long. corp. 6 lin.) 

 Cu. Ascanii. Linne.~Li. Ascanii. Steph. Catal. 182. No. 1860. 

 Cylindric, black, clothed above with yellowish powder : rostrum glabrous, black : 

 head with two whitish streaks before the eyes : thorax slightly convex in front,

I have seen a British pair of this species, I believe in the pos- 

 session of J. Sparshall, Esq. of Norwich, but I do not well remember.,

 mucronatis, antennis ferrugineis clavd nigrd. (Long. corp. 8-9 lin.)
