138 Rev. T. A. Marshall's monograph of 



rugulose. Metathorax bidenticiilate. Abdomen ^ with an oblong, 

 reniform anal fisaiire, thrice as broad as long, margmed and ciliated 

 all round. ^ J . Length, 1^ ; wings, 2f lin. 



Described from one male and ten females, all taken at 

 the same time and place. A second male in Fitch's 

 collection is rather doubtful, having the radial areolet 

 longer and more acute ; the antennse are 24-jointed, 

 and the other characters are those of the description, 

 except that the hind tibiae are testaceous only at the 

 base. Unless the sexes of these small species are taken 

 or bred together, and in some numbers, they can scarcely 

 be determined. Formerly found by me rather com- 

 monly on umbellate flowers in Leicestershire. Reinhard 

 examined 32 males and 37 females from central Europe ; 

 some of them were bred from Retinia huoliana, Schiff. 

 Brischke reared one from a Tortrix, and another from a 

 Gclcchia, perhaps G. midinella, Zell. ; he describes the 

 cocoon as 6 mm. long, elliptical, white, shining, and 

 transparent. 



The synonymy given above is that determined by 

 Eeinhard, with the exception of C. lugubris, Wesm., 

 Nouv. Mem. Ac. Brux., 1835, p. 219, ^ (wrongly called 

 ? ) ; and C. sulcatus, Jurine, Hym., 291, pi. xii., f. 41, 

 ? , which are both questionable. Jurine, it is true, is 

 the author of the name sulcatus, but his figure, un- 

 accompanied by a description, is a mere hieroglyphic 

 (as Wesmael remarks) ; the only thing certain is that 

 he has represented some species of which the ? has 

 16-jointed antenna. Thomson describes no sulcatus, 

 but observes that his C. deprcssus (Opusc. Ent., vi., 

 1874, p. 576, antennas 3" 21 -jointed) is much like 

 C. sidcatus, Wesm. He has also restored the confusion 

 which Eeinhard laboured to clear up, by making C. 

 lugubris, Wesm., a synonym of C. parcicornis, Thoms. 

 not of Schaff. and Reinh.), and by redescribing C.fene- 

 stratus, Nees, in terms altogether vague, as a distinct 

 species. C. parcicornis, Thoms., seems to be the following 

 species.
