dark brown spot near costa. Outside of this spot is a dash of whitish 

 scales. Running from apex across to inner margin, near its base, follow- 

 ing contour of hind margin, is an irregular dark brown line. Outside of 

 this line the ground color lightens, being very light at hind margin, dashed 

 with whitish scales and showing a few indistinct interspacial dark lines. 

 The fringe of hind margin is nearly white. Expanse .90 inch. 



Hab. Bolivia, near Cusilluni. 



Taken in May, 1899. Described from three specimens in 

 my collection. 



Thecla dickiei sp. nov. Head and eyes black. Antennae black, with 

 white annulations at the base of each joint. Club black, with orange tip. 

 Thorax above covered with blue-gray hairs ; below grayish brown. Ab- 

 domen blackish above, grayish brownish beneath. Legs black, with white 

 annulations at ends and centre of each joint. General color of wings 

 above nearly black. The upperside of forewings is entirely black, includ- 

 ing costa, except a brilliant dash of lustrous blue within a line drawn from 

 base through centre of discoidal space, then turning downwards to inner 

 margin. The blue occupies about one-third of wing area. The lower 

 wings are black, with the brilliant blue space of forewings repeated, but 

 covering only the basal quarter of the wing and not encroaching on inner 

 marginal space. Extending from the end of lower median nervule is a 

 delicate tail, black, with a white tip, about one-eighth inch long, and from 

 the nervule next above another, one-sixteenth inch long, with a white tip. 

 At anal angle is a small dot of rust color. The hind margin is edged with 

 a fine black thread. Both hind margins bear a slight fringe of gray-brown 

 hairs. The ground color of underside is a dead grayish brown. One- 

 sixteenth inch within hind margin of forewing is an indistinct whitish line 

 running downwards from about the third subcostal nervule to the inner 

 margin, bordered on the outside by an indistinct line of dark grayish 

 brown. Another and prominent white line runs from costa (at a point 

 one-third distance from apex to base) downwards to the lowest median 

 nervule. This line is distinctly edged with black on basal side, and forms 

 the most prominent feature of the wing. Starting from lowest submedian 

 nervule, one-sixteenth inch inwards from end of line just described, is 

 another similar line running to inner margin. There is also a linear white 

 dash across outer border of discoidal space. The prominent white line 

 of forewings extends downwards through the hind wing to the lower me- 

 dian nervule, and thence jaggedly to inner margin, forming a W in anal 

 angle area. The marginal indistinct white line of forewings also extends 

 through hind wing, swerving inwards at lower portion and joining the 

 first mentioned line at the lower median nervule. Below this point of 

 juncture, in the interspace, is a prominent rust-colored spot, with a black 

 speck at its lower edge. At the anal angle is a black spot with an adjoin- 

 ing semi-circle of white above it, and above that a semi-circle of rust 

 color, which extends upwards along inner margin. The border of hind
