 Certainly distinct from C. vuljpecula ; in the c5' the anal mar- 

 gin of the posterior wings is more deeply excised and less si- 

 nuate than in that species ; and the anal spot on these wings in 

 the $ is smaller and more quadrate. The coloration of the 

 wings is also different and approaches that in the 6 of C. Mac- 

 lachlani. Bcanvois's type is in De Selys's collection.

Rambur has evidently comprised C. vuljpecula and Maclachlani, 



* I liad intended anotlier name for this species ; but after the paper was read 

 I received the monthly 'Compte Rendu' of the Society Ent. de Eelgique, in 

 which De Selys, in a note on the species of Ascalaphi confounded imder the 

 term surinamensis, proposes to call it Maclachlani. 1 have no alternative but 

 .to acco))t his proposition.
