244 MR. B. h'lachlan on a systematic 



aureo-tinctae ; venis venulisque rufescentibus vel rufo-fuscis j ptero- 

 stigmate flavescente : margo analis posticarum in 6* profunde sinuato- 

 excisus j in $ leviter excisus, macula magna, irregulariter triangulari, 

 fusca notatus (interdum parte basali omnino fusco-suffusa). Long, 

 corp. o* 15"'; $ 12'"; exp. alar, antic. 37"', postic. 33"'. 

 Hab. Nicaragua to Minas Geraes. 



Apparently having a greater range of latitude than the allied 

 species. 



2. C. villosus, Palis, de Beauv. (Ascal. villosus, P. de Beauv. Ins. 

 Af. et Amer. p. 86, Nevrop. pi. vii. fig. 4.) Rufo-villosus. Antennae 

 fuscae, ad basin rufescentes ; clava ochracea. Abdomen fuscum, supra 

 rufo-maculatum. Pedes flavidi. Alse amplae, inaequales, fuliginoso- 

 tinctae ; venis venulisque nigricantibus ; pterostigmate sordide flaves- 

 cente : margo analis posticarum in S profunde excisus j in $ leviter 

 excisus, macula subquadrata, fusca, notatus. Magnitud. C. vulpeculce. 



Hab. San Domingo (P. de B. in coll. De Selys), Demerara (coll. 

 M'Lach.). 



Certainly distinct from C. vulpecula ; in the o* 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 <$ of C. Mac- 

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



3. C. Maclachlani, De Selys. (Cord, surinamensis, Ramb. Nev- 

 rop. p. 360, text, part., pi. 9. f. 1 (nec Fab.) — C. Maclachlani*, Selys, 

 Compt. Rend. Soc. Ent. Belg. 6 Mai, 1871.) Frons vertexque den- 

 sissime nigro-villosi. Antennae nigrae ; clava supra rufescente. Tho- 

 rax supra in medio densissime fulvo-griseo villosus, utrinque et infra 

 nigro-yillosus. Pedes rufo-testacei. Abdomen nigrum. Alae amplae, 

 inaequales ; in <J pallide fusco-tinctae : margo analis posticarum vix 

 excisus; pterostigmate brunneo, nigro-venato ; venis venulisque 

 nigris : anticae in $ ut in $ ; posticae ad basin late saturateque nigro- 

 fuscse, ad apicem fusco-suffusae ; margo analis leviter excisus. Mag- 

 nitud. fere ea C. vulpecula. 



Hab. Brazil. In De Selys's collection, olim Rambur's. 



Var. Paullo minor. Alae anticae in $ ad basin saturatiores ; posticae ad 



basin apicemque late et intense nigro-fuscae, nitidae. 

 Hab. Rio Ucayali [Bartlett). In my collection. 

 Eambur has evidently comprised C. vulpecula and Maclachlani, 



* I had intended another name for this species ; but after the paper was read 

 I received the monthly ' Compte Rendu' of the Societe Ent. de Belgique, in 

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

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



to accept his proposition.
