 base. Expanse 10 to 11.5 millimeters." 



Very few American collections contain specimens of botrana for com- 

 parison with viteana, so Riiey's description will be more valuable to the 

 average student. "Perfect insect: Average length 0.17; alar expanse, 0.37. 

 Head, thorax, palpi and basal half of antennae fulvous. Terminal half of 

 antennae darker. Legs fulvous, becoming darker on tarsi. Ground color of 

 forewings, pale slate-blue with slight metallic luster which becomes lighter 

 and somewhat silvery anteriorly and posteriorly. A dark rich brown band, 

 with a light, somewhat silvery annulation, proceeds from the middle of the 

 costa towards the inner margin, becoming paler anteriorly; its basal margin 

 being indistinct but running almost straight across the wing, its outer margin 

 well defined, curving to a rounded point which reaches to the middle of the 

 outer third of the wing and thence running obliquely inwards nearly to the 

 middle of the inner margin. Beyond this middle band is a large, deep brown 

 somewhat oval spot, also lighter below than above and with a pale annula-

tion, which is broken on the outer side above, allowing the spot to extend 

 to the margin of the wing. Above this large spot at the apex, is a small, 

 perfectly round dark spot, with a bright annulation inclining to orange color. 

 The space enclosed by the middle band, and these two spots just described, 

 are brown above with usually four lighter fulvous costal marks, quite distinct, 

 each mark divided at costa by a slight touch of brown. Another somewhat 

 triangular brown spot with a light annulation above, runs from the posterior 

 angle up between the middle band and a large oval spot. The blue space 

 from the middle band to the base of wing is generally brownish near base, 

 with a brown line across the middle from costa to inner margin, and with 

 two other costal brown marks. The fringes partake of the ground color. 

 Hind wings slate brown, darkest near margin; fringes same color. Body 

 brownish with frequently a clear green tint. The male differs principally in
