Si-BKAMiLY GEOMETRIXAE. 



Acollesis gen. nov. 



Fori'/r/nt/s: broad, the costa nearly straight ; hindmargin curved, but not very 

 oblique ; inner margin slightly convex. 



Hindwings : full, with well-rounded hindmargin and anal angle squared. 



Antennae in both sexes pectinated. Palpi porrect, short. Tongue present ; 

 frenulum absent. 



Seuration : forewings, cell not half as long as wing; discocellular angled; 

 first median at three-fourths, second shortly before end of cell ; lower radial from 

 close below upper angle ; upper radial stalked with the five subcostals ; 11 

 anastomosing with V2 and 10 with 11. Hindwings with costal closely approximated 

 to but not anastomosing with subcostal for half the length of cell; tlie two subcostals 

 stalked ; medians as in forewings. 



Tyj)e : Acollesis fmudiilciitu sp. nov. This insect aftords a very close 

 imitation of niwica, the type of Collesis ; but on comparing the two genera, 

 it will be seen that the neuratiou is quite different.

Forewings: very pale yellowish green, with a whitish line from four-fifths of 

 costa to three-fourths of inner margin ; fringe long, concolorous ; in the best-

Hindwings : with the line ])ostmcdian and slightly curved. 



Underside paler, without markings. Face, top of palpi, and forelegs red; 

 thorax and abdomen very pale green ; vertex and shaft of antennae white. 



Expanse of wings : tj, 27 mm.; ?, 29 mm.
