CELOTES.— CHIOMAKA. 453 



We have received three specimens of this species from Mexico and a similar number 

 from Texas ; these latter were sent us by Mr. Strecker. 



Celotes nessus has a very different appearance from all other Central-American species 

 of Hesperiidae we are acquainted with, from its alternately light and dark radiating 

 lines on both wings, extending from their base to the outer margins, and also by the 

 presence of small hyaline spots scattered over their surface. The outer margin of the 

 secondaries is crenulated. 



CHIOMARA, gen. nov. 



Achlyodes mithrax, Moschl., clearly belongs to the section of Hesperiinae having 

 blunt antennae as in true Sesperia, and for this insect we propose the name Chiomara, 

 and associate with it Thanaos gesta, Herr.-Sch., and Papilio asychis, Cram. Neither 

 of the latter is quite congeneric, as in both the terminal joint of the palpi is longer 

 than in C. mithrax. C. gesta resembles C. mithrax in its dark coloration, but the palpi 

 have a longer terminal joint. C. asychis differs in coloration as well as in having 

 rather longer palpi. The last-named species was placed in Fphyriades by Plotz, and 

 in Hesperia by Watson. Though close to the last-mentioned genus, it differs in 

 several points, such as the total absence of a costal fold in the male, so that it had 

 best be kept apart. 



As common characters all these species have rather short hollow wings, the primaries 

 of the male have no costal fold, the tibiae carry a distinct tuft, and the harpes of the 

 male genitalia are unsymmetrical, but not so much as in Thanaos.
