90 APPLE LEAVES — CHRYSOPA SPECIES. 



orange yellow. Eyes brilliant coppery red with a golden j-ellow reflection in 

 the living specimen. Antennas white. Palpi white, their tips brownish. 

 Thorax pale yellow above, pale bright green on each side, bluish white beneath ; 

 first segment with a row of three equidistant bright orange spots on each side, 

 the anterior one largest and placed rather more outwardly, an impressed trans- 

 verse line across the middle; second segment with an impressed longitudinal 

 line crossing the two anterior elevated lobes, and a bright orange spot on each 

 side on the anterior edge. Abdomen pale greenish yellow with a deeper bright 

 yellow stripe above, on each side of which on the five first segments is a bright 

 orange spot, each spot crossed by an impressed longitudinal line, those on the 

 second and third segments larger, their centres tawny; those on the fifth 

 segment small and pale. Legs pale bluish white, feet yellowish. Wings ob- 

 tusely angular at their tips, the fore ones very slightly so; stigma opake pale 

 green; veins pale green, the marginal one white; veinlets pale green, the two 

 series towards the tip and the ends of most of the others black. Wings ex- 

 pand 1.05. Taken the first of August. This is the most variegated of our 

 American species belonging to this genus. I name it in honor of my esteemed 

 friend and correspondent, Dr. Sichel, President of the Entomological Society 

 of France. 



34. (33.) No orange spots along the sides of the back. 



The New- York Golden-eye ( C. NovcEboracensis'). Pale green with a pale 

 yellow stripe from the mouth the whole length of the body. Eyes dark green- 

 ish golden when alive. A bright orange red stripe between each e} r e and the 

 mouth. Sides of the head greenish white. Palpi pale dull yellowish, tips 

 black and a black line on their outer side. Antennas whitish slightly tinged 

 with dusky towards their tips. Thorax commonly with a large blackish spot 

 anteriorly on each side, formed of two or three confluent smaller ones. Be- 

 neath greenish white. Legs very pale green, feet yellowish white. Wings 

 angular at their tips, the hind ones more conspicuously so, veins pale green; 

 veinlets black at both their ends except those ending in the inner and apical 

 margin, the two series of veinlets towards the tip entirely black; veinlets of 

 the outer cell of the hind wings black at both ends, those branching from the 

 inner side of the rib vein black at their bases. A variety has the veinlets 

 marked with dark green instead of black. Wings expand 1.05. Common the 

 latter part of June and through most of the month of July, depositing its eggs 

 singly, commonly on the margins of apple and other leaves, elevated upon 

 threads the tenth of an inch long. This, like some of the other species, is per- 

 fectly inodorous. 



35. (30.) Veinlets entirely pale green or white. 



36. (37.) Stigma hyaline, scarcely obvious. 



Harris's Golden-eye (C Harrisii). Like the preceding in all respects, 

 except that it is slightly larger and the veinlets of the wings arc greenish white 

 without any traces of dark green or black at their ends. Wings expand 1.15. 

 Taken the last of July and in August. Its cocoon is smooth, of a bright pale 

 green color and a regular oval form, 0.14 long by 0.11 in diameter, whilst 

 that of the preceding species is rough externally, with numerous threads loosely
