88 ON THE SYNONYMY OF THE PERLITES. 



ings of a faint brown hue ; the nervures of the fore wings are brown, in the 

 hind wings the marginal nervure alone is of this colour : the caudal setce are 

 pale green, with brown rings; the joints of *the setce in this species are un- 

 usually long. 



Inhabits Georgia. There is a single specimen in the cabi- 

 net of the British Museum. In the abdomen of this specimen 

 I observed, through the transparent cuticle, a large Filaria ; 

 it is coiled up in several rings, and occupies a very consider- 

 able portion of the cavity. 



** Species normales. 



These have usually nine nervures reaching the margin of 

 the forevving between the subcostal nervure and the base.

Yellow green, the tips of the antenna, the eyes, and ocelli black, the pro- 

 thorax is almost circular, with reflexed margins and longitudinal wrinkles, 

 the margins are also very distinctly brown : the abdomen is yellowish, with 

 a dorsal fuscous line. 



Common in Europe and England. There are specimens in 

 nearly all collections of British insects.

Entirely of a delicate yellow green, with the eyes and tips of the antennae 



black : the prothorax nearly quadrate and perfectly concolorous, tarsi dusky. 



Inhabits Europe and England. Specimens in nearly all 

 collections of British Insects. 



Sp. 8. Chlo. Cydippe. Pallide lutea, alis venuste virescentibus, nervu- 



ris concoloribus; antennae fuscae, basi imo tantum luteae. (Corp. long. 



.15 unc. alar, dilat. .5 unc.) 



Pale yellow, the wings beautifully tinged with green, the nervures being 



exactly concolorous, and not observable without some difficulty ; the an- 



tenncB are brown, the extreme base alone being yellow. 



This insect nearly approaches Chlo. apicalis, which ap- 

 pears identical with Chlo. pallida of Stephens, a species not 

 uncommon in Great Britain, France, and Switzerland ; but 

 the antennas are differently coloured, and several other slight 

 discrepancies are observable on a minute comparison.
