APPLE LEAVES-^CHRYSOPA SPECIES. 91 



extei-nally, with numerous threads loosely attached to its surface, and of a ■white 

 color and a globular form. I have heretofore regarded this species as the Chrysopa 

 PeHa of Europe, and it is probably the species designated under this name by Dr. 

 Harris (New England Insects, page 215). It does not appear to be fully settled to 

 what species this name is to be applied, the British entomologists (Curtis, Journal of 

 the Royal Agricultural Society, iii. 63; Stephens, Illustrations Mandib. vi. 105) de- 

 scribing a different insect from that of Rambur (Neropteres, p. 424). But on com- 

 paring our species with the full descriptions given by these authors, it is evidently 

 distinct from both the European species that have received this designation, neither 

 of which appear to possess a paler dorsal stripe and some other marks belonging to 

 our insect.* 



37. (36.) A blackish brown opake spot on the stigma. 



The ViRQiKiA OOLDEN-EYE (C. Virginica) . Immaculate, save a blackish spot on 

 each side of the thorax at its apex. Wings slightly angular at their tips, veins and 

 veinlets pale green, those branching from the inner side of the rib vein faintly tinged 

 with dusky at their bases ; first veinlet of the second row towards the tip black and 

 margined with smoky ; stigma with an opake brown spot, more strongly marked on 

 the hind pair. The small semi-oval cell which is formed in the straight mid-vein to- 

 wards its base in all our other species is here irregularly quadrangular, and bounded 

 by straight veinlets on each of its four sides. Wings expand 1.35. Taken in Vir- 

 ginia, near Cartersville, by the late Thaddeus A. Culbertson, of Chambersburg, 

 Pennsylvania, whose love of science and activity in its pursuit, rendered his early 

 death a loss to our country. 



38. (19) Cheeks pale and without any spot or dot. 



39. (42.) Antennse black towards their bases. 



40. (41.) A black stripe on the outer side of the basal joint of 

 the antennse. 



The Stkipe-horned goiden-ete (C. lineaUcornis) . Pale green. Head white, 

 greenish on the top with two or three small dark brown dots on each side anteriorly, 

 upon the upper edge of the sockets of the antennre. Antennae pale brown, basal 



*,Next to the Perla Fabricius describes a species from the Society Islands in the Pacific 

 ocean, which he met with in the cabinet of Sir Joseph Banks, which is rather larger than Perla 

 and of an ash gray color with whitish wings and antennae double the length of the body, from 

 which last character he names it filosus, or the Threadlike golden-eye. I have specimens 

 from the same locality, presented to me by Lieut. Pattison, U. S. Navy, which are perhaps the 

 same species, as they coincide with the description in most of its points. They however are 

 rather smaller than Perla, the wings expanding from 0. 76 to 0. 90, and only the posterior part 

 of the thorax is ash grey, its anterior part and the head being bright yellow and without spots. 

 The antennse are double the length of the body, blackish, becoming yellow at the base, with 

 a black dot on the upper sideof the basal joint ; the wings white, hut pellucid, their veins and 

 veinlets pale dull yellow. Should this prove to be different from the Fabrician species, aa it 

 apparently is, it may appropriately be named the Chrysopa filicorms, or Thread-horaed 

 golden-eye.
