Macaira is figured by Hewitson^^ as locutia Hewitson from the 

 Island of Taboga, Panama. 



The uncus is proportionately smaller than that of the two 

 preceding species, its projecting beaks are similar, but this 

 species lacks the arms projecting from the sides of the girdle. 

 The valve carries at its apex on the ventral lobe a stoutly 

 t horned process; the aedoeagus is simple. 



Records: Texas, Corpus Christi (Aaron) ; iMexico, Mazatlan, 

 Coliina, Sonora.

This insect is reported from Brownsville, Texas, as is also 

 typical macaira. It is well figured by Godman and Salvin^^, 

 who state, as we find to be the case, that the genitalia are the 

 same as those of macaira. 



Records: Mexico, La Joya, Colima, Yucatan.

Biol. Ccnt.-Ainer., Rhopalocera, pi. 91, fig. 29, (1899). 



This species has the costal fold and tibial tuft. 



Lindsey places it in the genus Systasea with pidverulenta. 

 It has, however, a veiy different appearance, and the genitalia 

 also differ so decidedly that this association can hardly hold. 

 Its near allies are of the genus Carcharodus, but a comparison of 

 the genitalia with those of mnlvanun Hoffmannsegg (= alceae 

 Esper), with which it was associated l)y Strecker when he 

 des(;ril)ed notahilis (= nessus), does not disclose a sufficient 

 similarity to necessitate its transfercnice to Carcharodus, and we 

 therefore place it in Celotes, which Godman and Salvin erected 

 for it. 



The uncus is short with split terminals; the scaphium promi- 

 nent and set well up on the uncus; the saccus is produced into 

 the abdomen more than in other species of the allied groups; 

 the ventral lobe of the valve, extended bej^ond the dorsal lobe 

 is serrate on its recurved outer margin; the aedoeagus is rela- 

 tively large and long and l)ears a tooth near its apex.
