APPLE LEAVES CHRYSOPA SPECIES. 91 



attached to its surface, and of a white color and a globular form. I have here- 

 tofore regarded this species as the Chrysoj a Perla of Europe, and it is proba- 

 bly the species designated under this name by Dr. Harris (New England In- 

 sects, 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) descri- 

 bing a different insect from that of Rambur (Neroptcres, p. 424). But on 

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

 evidently distinct from both the European species that have received this de- 

 signation, 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 Virginia Golden-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 towards 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 Virginia, near Cartersville, by the late 

 Thaddeus A. Culbertson, of Chambersburg, Pcnnsjdvania, whose love of sci- 

 ence 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.) Antennae black towards their bases. 



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

 of the antennae. 



The Stripe-iiorned g6lden-eye ( C. lincaticornis'). 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 antennse. Antennse 

 pale brown, basal fourth part of their length black, basal joint white with a 



* 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 hare specimens 

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

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

 rather smaller than Perla, the wings expanding from 0.75 to 0.90, and only the posterior part 

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

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

 a black dot on the upper side of the basal joint; the wings white, but pellucid, their veins and 

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

 appirently is, it mxy appropriately be named the Chrysopa filicomis or Thread-horned 

 golden-eye.
