IO4 ILLUSTRATIONS OF UNFIGURED LEPIDOPTERA. 



Pythonides hirta A. G. Weeks, Jr. 1 



(Plate XLV, Figure 2.) 

 Habitat: Bogota district, Colombia. Expanse: 1.50 inches. 



Head, palpi, thorax and abdomen, above, dark mouse color; beneath 

 nearly white. Between the eyes are three white dots. Antennae black. Legs 

 grayish white. 



Upper side of fore wing dark mouse color. There is a broad prominent 

 yellowish white band extending from costa down to submedian nervure, its inner 

 edge straight, the outer edge swelling outward somewhat. The interspaces 

 between this distinctive band and the hind margin, also the interspaces upward 

 toward costa, are heavily dusted with light mouse-colored scales. The 

 nervures and nervules are nearly black. The hind margin bears a slight hairy 

 fringe and a very slight darkish thread. 



Upper side of lower wing dark mouse color. There is a broad white area 

 covering central half of costa and extending downward to the median nervure, 

 suffusing somewhat toward hind margin. Outside of this area the interspaces 

 show a little lighter shade than the ground color. The nervures and nervules 

 are dark. The hind margin has a slight hairy fringe and a very slight darkish 

 thread. 



The yellowish white band of fore wing and the white band or area of lower 

 wings form the prominent marking of upper surface. The rest of the wing is 

 of dark color, with the slight variations above noted. 



The under side of fore wing is divided between white and dead mouse color. 

 The basal portion within a line drawn from centre of costa down to lower angle 

 is white. The rest of the wing (the apical area) is dead dark mouse color, the 

 interspaces showing white dashes starting at subcostal interspaces midway 

 between the apex and the edge of the white area. The hind margin has a 

 hairy fringe and a darkish thread. 



The lower side of hind wing is white, excepting a broad hind marginal 

 border of dark mouse color, which suffuses upward toward base as it reaches 

 the anal angle. At the upper angle there is a suggestion of a white line running 

 through this border just within the margin, but it is very indistinct. The hind 

 margin has a slight hairy fringe of mouse color and a darkish thread. In some 

 lights the basal area of both wings shows a bluish gray tinge. The prominent 

 bands of the upper side also show slightly, owing simply to transparency. 



Taken in 1896. A duplicate of this species was found in the 

 Godman collection unnamed, and undoubtedly it has never been 

 described.
