DESCRIPTION of A NEW GENUS and SPECIES of TEXTHREDISID&. 



BY W. F. KIRBY, 



Assistant in the Zoological Department, British Museum. 



Parastatis, g. n. 



Wings and body as in Tentliredo (true) ; antennae 8-jointed, joint 



3 nearly twice as long as joints 1 and 2 together; and joints 5 to 8 



forming a club, tapering at both ends ; joint 4 being longer than any 



of the remainder, and gradually expanded ; and joint 8 ending in a 



point. The club is about as long as the first three joints together. 



Parastatis indica, sj?. n. 

 Head black, coarsely punctured, clypeus aud labrum nearly smooth, with a few 

 scattered punctures, clypeus incised, yellowish, as is also the outside of the mandibles 

 at the base ; labrum with a longitudinal impression in the middle. Thorax and 

 pectus black, punctured, segments of the abdomen blue-black in front, and yellowish 

 behind, the last two segments almost entirely yellowish above, and blue-black below. 

 Four front-legs yellowish, their femora and tibiae, and the first two joints of the 

 middle tarsi, blue-black on the outside. Hind-legs blue-black, with yellowish coxae 

 and trochanters. Wings yellowish-hyaline, with a strong violet iridescence, es- 

 pecially over a dark shade at the tip of the fore-wings, extending over the greater 

 part of the radial cells, and a little below them ; there is also a dark shade filling up 

 the greater part of the first medial cell. Costa and stigma ochraceous, the latter 

 blue-black at the base. Exp. al., 12 lin. ; long. Corp., 6 lin. 



India (collected by Mr. Farr; precise locality not recorded). 



A single female example is in the collection of Mr. F. Moore, to 

 whom I am indebted for the permission to describe it. The insect is 

 chiefly remarkable for the structure of its antenna?, which are quite 

 different from any previously described form occurring among the 

 Tenthredinidce. A figure will shortly appear in Mr. C. 0. Water- 

 house's " Aid to the Identification of Insects."

ON A NEW SPECIES OF CHARAXES FROM WEST AFRICA. 

 BY ARTHUR G. BUTLER, F.L.S., F.Z.S., &c. 



We have recently received a small series of butterflies, chiefly 

 Charaxes, from Accra, amongst which is the insect figured by Ilewit- 

 son (Exotic Butterflies, vol. v, p. 40, pi. xx, figs. 22, 23) as the female 

 of his Charaxes cedreatis. 



As both figures of C. cedreatis evidently represent females of 

 perfectly distinct species, and as the true male of Hewitson's C. ce- 

 dreatis, $ , is sent with the female by Mr. Carter, and proves to be an 

 insect which has long stood in our collections as a probable variety of 

 C. Etheocles, it will be necessary to give a new name to this species.
