tennae with an apical jjlate ; sciitellum with a black, triangular spot near 

 each basal angle ; clavus with a distinct white blotch around the apex 

 of the central nerve ; corium without a transverse band. 



Head : crown pale or clear yellow in front, generally with a more or less distinct 

 brown spot near each eye. Face and clypeus pale yellow. AntenncB : apical 

 plate somewhat large, ovate, black. 



Thorax : pronotum brown or brownisli-rellow, anterior margin sometimes yellowish ; 

 disc, anteriorly, with four short, transversely placed, black streaks. Scutellum 

 clear yellow, frequently next the ajjex yellowish-white ; near each basal angle 

 is a triangular black spot ; middle of the disc generally brownish or brown. 

 Elytra : clavus yellow ; inner margin, from the base to round the scutellar 

 region, blackish, from thence to the central nerve yellow, and from the latter to 

 the apex blackish ; central nerve fine, white, around its apex a distinct, some- 

 what oval, white blotch. Corium yellow between the claval suture and the 2nd 

 longitudinal nerve, from thence to the anterior margin pale testaceous ; nerves 

 fine, white, delicately punctured along each side. Membrane slightly brownish- 

 yellow ; marginal nerve round the apex of the inner margin, and the apex of 

 two or three of the cell nerves, brown. Legs yellow ; thighs with a short, black,

 clothed with long pale hairs. Length, 2^ — 2'i lines. 



Resembles /. laminatus in having a white blotch in the clavus, but 

 there all likeness ends, as it is without the pale transverse baud on 

 the elytra exhibited by that species. Sometimes the ^ of I. populi has 

 the head, sternum, abdomen (beneath), and legs of an orange colour. 



Common everywhere upon sallows and poplars from the end of

DESCRIPTION OF TWO NEW GENERA AND THREE NEW SPECIES 

 OF ANTHRIBID^ FROM NEW ZEALAND. 



BY D. SHARP, M.B. 



The insects here described have been sent to me by Mr. R. Lawson
