rondacks, from Pennsylvania, and from 

 Sudbury, Ont., Canada. At Jackman, 

 Me., it has been found in " open woods 

 and bogs'' (Harvey, — Psyche, 1897, 

 p. 77). Mr. Scudder states that "it 

 frequents the close branches of the 

 dwarf birch" in the White Mts. Some 

 of my specimens were obtained from 

 birch but most were found on or among 



the various species of Vaccinium char- 

 acteristic of the mountain-tops, and on 

 Ascutney among dwarf cornel. It is 

 a somewhat sluggish insect, relying 

 chiefly for protection upon the similarity 

 of its dark olive green coloring to that 

 of the surrounding vegetation, though on 

 warm days the males become fairly 

 active. 



A NEW PARASA, WITH A PRELIMINARY TABLE OF THE SPECIES 

 OF THE GENUS. 



EV HARRISON G. DYAR, WASHINGTON, D. C. 



The Eucleid genera Euclea and Parasa 

 are closely allied and indeed not well 

 separated. There is a stronger ten- 

 dency to the stalking of vein 10 of 

 primaries in Euclea, but some species 

 of Parasa show the same character. 

 Judging from the American larvae alone 

 there appear to be marked differences 

 in the early stages of the genera ; but 

 the larva of P. lepida, a true Parasa, 

 shows the more generalized Euclea 

 form, proving that our P. chloris is a 

 specialized offshoot, not a characteristic 

 type for the genus. 



Parasa is a widespread genus, being 

 represented in all the continents except 

 Australia and Europe. The following 

 are its characters : — 



Head partially sunken, untufted ; palpi 

 upturned, reaching half way to the ver- 

 tex, third joint small, evenly clothed. 

 Antennae of male pectinated on basal 

 half, the tip simple, the two regions 



usually sharply marked off, occasionally 

 grading into each other; simple in 

 female. Thorax smoothly haired, not 

 scaly. Abdomen extending moderately 

 beyond hind wings. Legs densely 

 hairy ; posterior tibiae with one pair of 

 spurs. Fore wings with the costa 

 straight, rarely convex, outer and inner 

 margins rounded ; two internal veins, 

 2 to 5 rather regularly spaced, 4 and 5 

 nearest at base ; 6 from cross-vein, 7 to 

 9 stalked, rarely 10 also shortly stalked, 

 II from cell, 12 from base; discal vein 

 often forked and open. Hind wings 

 with three internal veins, 2 to 5 regu- 

 larly spaced, upper half of cell retracted, 

 6 and 7 usually stalked, 8 anastomosing 

 with cell toward base with more or less 

 distinct line veinlets thrown off toward 

 costa. 



Parasa prasina n. sp. — Vertex of head 

 and thorax green, a few brown hairs at base 

 of fore wings and a very narrow central
