externally, with numerous threads loosely attached to Us surface, and of a white^ 
color and a globular form. I have heretofore regarded this species as the Clmjsopa 
Perla 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, IllustrationsMandib. vi. 105) de¬ 
scribing a different insect from that of Rambur (Neropteres, p. 424). But on com¬ 
paring our speries 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. 
T1 e Virginia golden-eve (C. Virginica ). Immaculate, save ablackish spot on 
each side of the tjiorax at its apex. Wings slightly angular at their tips, veins and 
veinlets pale green, those blanching 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 135. Taken in Vir¬ 
ginia, near Cartersville, by the late Tha Idcus 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.) Antensse black towards their bases. 
40. (41.) A black stripe on the outer side of the basal joint of 
the antennte. 
The Stripe-horned golden-.eye (C. lineaticornis). 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 antenna}. Antenna: pale brown, basal 
• Next to tho 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 . sb gray color with whitish wings and antenme doublo the length of the body, from 
which last character ho names it Jilosus , 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 , tho wings expanding from 0 75 to 0 90, and cnly the posterior part 
of the thorax is ash grey, its anterior part and the head being bright yellow and without spots. 
The antennai are doublo the length of tho body, blackish, becoming yellow at tho base, with 
a black dot on the uppor side of the basal joint; the tvings white, but pellucid, their veins and 
yeinle's pale dull yellow. Should this prove to be different from the Fabrician species, as it 
apparently is, it may appropriately be named the Chrysopa Jilicornis , or Thread-horned 
golden-eye.
