native land nor abroad. As the ' ' Genera of Diurnal Lepidop- 

 tera" is an extremely rare work— it is doubtful if more than fifteen 

 copies are to be found in the United States — I have thought it 

 well to describe and figure it at this time, so that hereafter it may- 

 be easier for the American student of the Hesperid^ to identify 

 the species as it turns up in collections. 



The only textual reference to this species in the ' ' Gen. Di. Lep. ' ' 

 is in a list of the species of the genus ; the student is left to the 

 very accurate figure on plate 79 for the determination, and there, 

 very unwisely as it seems, only the upper side is figured. 



The description which follows is made from the figure by Mr. 

 Hewitson, and* from a fair series of specimens from Texas and 

 Mexico : 



Expanse 2 to 2^ inches. Ground color above black on both 

 wings ; banded and spotted with bright green or blue. On the 

 primaries this banding in most examples is caused by the fact that 

 nearly the whole surface is covered with a dense coat of scales of 

 bright green, which, being separated by the black bordered ner- 

 vures, take on the form of longitudinal bands; in a few specimens, 

 however, the apical area is but slightly sprinkled with green and 

 the whole outer half of the wing appears black or nearly so. A 

 group of translucent sub-apical spots consist of three constricted 

 points along the costal margin, one larger below the outer of the 

 three, and a much larger quadrate spot centrally below the four. 

 Two translucent bands follow these spots internally, the first bifid, 

 short, hardly more than an elongated spot, the inner one crossing 

 the median area much longer and made trifid by two nervures. 

 The color of the markings on the secondaries is much brighter, 

 and towards the anal angle of a deep azure-blue tint in some ex- 

 amples. From the base three streaks diverge towards and stop 

 abruptly on the median area, the upper of these is shorter than 

 the others to make room for the bifurcate series of spots on the 

 outer area of the wing. These spots — four in the inner limb and 

 seven in the outer are placed in the form of a written letter jj/. On 

 some examples there is a faint indication of another streak, longer 

 than the three others running parallel to the abdominal margin. 



Beneath, color and markings a reproduction of the upper sur- 

 face, save that while the black is not so dense on the primaries, it 

 is deeper and more velvety on the secondaries. The green atoms 

 on the primaries are fewer ; on the secondaries they are brighter, 

 and the bands run all the way to the costal edge.
