 ramos medianos primum et secundum maxima, una (interdum duabus) subapicali, omnibus albo-

 Ameeica to Cayenne x 2 and Brazil 2 , Trinidad. 



We have nine Central- American specimens of this species before us ; they only 

 differ from those in our long series from South America in having rather more white 

 at the anal angle of the secondaries above, and the fuscous lines on the underside of 

 the same wings are fainter *. We have dissected a male from Bugaba and another from 

 Santarem, and find no difference in their genitalia, for which see Tab. CII. fig. 10. 



5. Carystus aurelius. (Tab. en. figg. 11, 12, $ .) 



Hesperia aurelius, Plotz, Stett. ent. Zeit. 1882, p, 455 l . 



C. rnarco similis, sed posticis plaga discali alba posticarum ad angulum analem extendente et subtus area ad 



angulum analem alba, nee fusca. 

 2 mari similis. 



Hab. Nicakagua, Chontales (Belt). — Colombia ; Venezuela ; Beazil \ 



This insect, of which we have two pairs from Chontales, as well as several others 

 from South America, is scarcely anything more than an extreme form of C. marcus 

 (Fabr.), from which it differs in having the white discal patch on the upperside of 

 the secondaries extending to the anal angle, this being particularly noticeable in the 

 females. The genitalia of the males, two specimens of which have been dissected, do 

 not differ from those of C. marcus and C. diversus. 



6. Carystus diversus. (Tab. CII. figg. 13, 14, <? .) 



Cobalus diversa, Herr.-Schaff. Prodr. Syst. Lep. iii. p. 79 \ 



Hesperia diversa, Plotz, Stett. ent. Zeit. 1882, p. 454 2 . 



Carystus maon, Mab. Compt. Rend. Soc. Ent. Beige, xxxv. p. exx 3 . 



C. marco persimilis, sed subtus venis posticarum marginem externum versus fuscis, nee albis. 



$ mari similis. 



Hab. Nicaeagua, Chontales (Belt) ; Costa Kica, Cache (Bogers) ; Panama, Volcan 

 de Chiriqui (Champion), Chiriqui 3 .— Bolivia ; Beazil 2 . 



C. diversus is probably yet another form of C. marcus, from which it differs in having 

 the nervures of the underside of the secondaries fuscous towards the outer margin. 



* O. marcus has by some authors been treated as synonymous with Papilio phyllus, Cram, (which is here 

 referred to a different genus), but this is a mistake, the latter having a conspicuous brand on the primaries in 

 the male.
