HESPEEIA. 451 



U. synchto similis, alis ad basin multo fuscescentioribus, pilis griseis vix vestitis, serie marginali macularum 

 evanescente, vix obvia ; anticis plica costali obvia ; tibiis posticis hand penicillo instructis. 



Hab. North America, Western States, Arizona.— Mexico, Pinos Altos in Chihuahua 

 (Mohan-Hepburn), near Durango city (Becker), Aguas Calientes (F. G. B.), Puebla, 

 Orizaba (H.J.Ehues), Lake Chapada (W.B. Bichardson), Morelia, Patzcuaro, Misantla 

 (F. B. 67.), Cordova (Bilmeli), Valladolid in Yucatan (Gaumer) ; Nicaragua, Matagalpa 

 (Bichardson). 



Reakirt's description x of this species was based upon specimens from Colorado and 

 from " near Vera Cruz " in Mexico. Mr. Scudder 2 gives his H. tessellata a wide range 

 over the Eastern States of North America, as well as California. There can be little 

 doubt that the two names refer to the same species, for though neither author mentions 

 the male characters of the costal fold and the absence of the brush of hairs on the 

 proximal end of the hind tibiae, both refer to the evanescent character of the marginal 

 row of white spots, as compared with their greater size in H. syrichtus. 



Plotz and others place the name H. montivaga as a synonym of //. syrichtus, but 

 they can hardly be correct, for, apart from the difference, pointed out above, of the size 

 of the submarginal row of spots, the distribution of the two species is very different — 

 H. montivaga being a northern insect not passing beyond the limits of Nicaragua, 

 while H. syrichtus is essentially a southern one and does not enter the States at all. 

 The difference of the male genitalia seems conclusive as to the specific distinction 

 of the two forms. 



The range of H. montivaga in Mexico is very general, and extends from the northern 

 frontier States to Vera Cruz and Yucatan. 



The male genitalia differ from those of H. syrichtus in the harpes having a long 

 narrow rod starting backwards from the dorsal edge of the terminal lobe and reaching 

 nearly to the base ; the scaphium projects further, but is less strongly developed and 

 rounded, not serrated at the end. (See Tab. XC. fig. 30.) 



3. Hesperia notata. (Tab. xc. figg. 31, 32 6 .) 



Syrichtus notatus, Blanch, in Gay's Fauna Chil. vii. p. 45 l . 



H. montivagce persimilis, et alis fere eodem modo picturatis, fascia mediana alba posticarum forsan angustiore 

 et minus sinuata ; mare nee anticis plica costali nulla, neque tibiis posticis penicillo instructis.
