Distribution. Nearctic, Pala3arctie and Oriental Regions. 



Osboru and Ball (supra) have so fully described this genus that 

 I copy their diagnosis : — 



" Head (together with the eyes) wider than tegmina at base ; 

 vertex transverse, crescentiform ; ocelli on the face between the 

 eyes ; antennae long, inserted under a feeble ledge, their bases 

 partly visible, clypeus longer than wide, nearly rectangular ; face 

 as long or longer than width across eyes ; pronotum long, anterior 

 margin strongly rounding and extending forward below the eyes, 

 side margin short or obsolete ; tegmina without an appendix, five 

 apical and three subapical cells, second transverse nervure some- 

 times present ; marginal nerve of wing continued around apex, 

 forming a supernumerary cell. In the Nearctic species colour 

 varying from whitish to dark fuscous, scarcely ever more than a 

 trace of I'ed, yellow or green, two round black spots on vertex 

 rarely wanting." 



The above writers state that in the North -American species of 

 Agallia the males are invariably smaller and darker than the 

 females. They are all single-brooded so far as known, the larvae 

 being usually found in the rubbish on the ground around the base 

 of their respective food-plants, from which they emerge to feed. 



There is a considerable disparity in the general appearance of 

 some of the species in this genus. 



2411. Agallia plotina, sp. n. 



S . Vertex, pronotum and scutellum ochraceous ; eyes and a 

 small elongate spot at each basal angle of scutellum fuscous ; 

 body beneath and legs ochraceous, some lateral spots (sometimes 

 fused) to sternum piceous ; tegmina fuscous, the claval area 

 inwardly brownish-ochraceous, its outer area stramineous ; apex 

 and costal margin paler. 



5 . Tegmina more uniformly fuscous-brown, the claval area 

 only pale ochraceous at base of outer margin and apex. 



Pronotum somewhat coai'sely transversely Avrinkled, slightly 

 granulose at lateral areas ; scutellum a little centrally transversely
