strongly intermingled with fuscous (but not irrorated with spots) ; the usual whitish 

 spots on the transverse nervules are large and distinct, and there are other large pale 

 spots in the membrane, especially towards the middle of the inner mai-gin and at 

 the base of the apical cellules ; fringes dark greyish-fuscous ; neuration as detailed 

 at p. 406. Posterior-wings dark smoky-grey, with concolorous fringes and fuscescent 

 neuration. 



In the S the anal parts resemble those of C.flavidus rather than those of C. 

 trimaculatus. The dorsal plate is subquadrate, with its apical margin deeply excised, 

 leaving the outer angles rounded, and there are (apparently) none of the intermediate 

 appendages and sheaths so prominent in C trimaculatus. Also the superior 

 appendages are quite as large as the inferior, therefore much as in C.flavidus. 



In the 9 the anal parts appear to be much as in C. trimaculatus.

France (Paris, Bamhur, 1 $ type in De Sely's collection ; 1 cj ,

 Switzerland (Katzensee, His, 31st July). 



Having been able to compare Eambur's type $ with the ^ col- 

 lected by Mabille, I feel sure they are specifically identical, and that 

 a larger ? taken by Mabille also belongs here. I also feel sure that 

 insolutus is a good species. At first sight it might be passed over as 

 a variety of trimaculatus, in which the irrorations of the wings were 

 absent, but the numerous transparent spots in the membrane (which 

 show through the pubescence if the wings be held against the light), 

 the neuration, and the anal parts (especially) differ ; in the anal parts 

 there is some amount of resemblance to flavidus, but all other charac- 

 ters differ ; finally, in the presence of the numerous pale spots in the 

 membrane there is resemblance to crenaticornis, but in no other point, 

 for ci^enaticornis is a very delicate pale species, with the antenna 

 strongly crenate for nearly their whole length. 



It will have been seen (Rev. and Synopsis, p. 407) that I wa» 

 formerly not inclined to place much stress upon Eambur's words^ 

 " paraissant avoir de petites marques plus pales vars le milieu et sur 

 I'extremite " of the wings, but viewed in the light of further materials 

 these words had greater significance. Dr. Eis's description is very 

 full, and is accompanied by figures of the wings and appendages of 

 the ^ ; he generously presented me with a series of types, which are 

 darker than the Parisian examples.
