ILLUSTRATIONS OF UNFIGURED LEPIDOPTERA. 41 



Described from two specimens in my collection secured by 

 my collector, Mr. William J. Gerhard, at a point five days 

 north from Cochabamba, Bolivia. In all the collections exam- 

 ined, including the largest collections in this country and in 

 England, only one of this species was found, that being in the 

 Hewitson collection, unnamed. 



Heliconius spadicarius A. G. Weeks, Jr. 1 



(Plate IX.) 

 Habitat: South America. Expanse: 3.50 inches. 



Head black, with four light yellow spots at collar ; also a yellow speck 

 above each eye. Palpi black above, light yellow beneath. Thorax above 

 black, with a light yellowish white spot at base of each wing, and between 

 these, close to collar, are two more. These are grayish in some specimens. 

 Centre of thorax above tends to dark grayish, and near its end is a semicircle of 

 light yellowish. Thorax below, black, with a light yellow dash running 

 from shoulder to lower end. Abdomen black above, light yellow below; a 

 light yellow thread runs from thorax joint to tip just above the yellow under 

 side. Fore legs above, black ; below, light yellow ; other legs black. An- 

 tennae black, turning to light tawny half-way to club. 



The basal portion of upper side of fore wing, from a line drawn from 

 centre of costa to lower angle, is dark tawny. Costa black. Through 

 centre of discoidal space, starting at base, is a black dash broadening out to 

 a well-defined spot at longitudinal centre of the space. The black of the 

 costa suffuses downward at end of the discoidal space forming a band one 

 quarter inch wide, running to lower edge of the discoidal space. Outside of 

 this is a series of yellow elongated spots, the first at the costa, the fourth 

 extending out nearly to hind margin and having a black spot or dash at its 

 inner end, bordering discoidal space. In interspace below this spot is 

 another of anvil shape, bordered on its inner and outer edge by black dashes. 

 These black dashes are prominent black spots in some specimens. The 

 apical space outside this series of yellow marks, and covering one third of 

 the wing, is black, with three transverse light yellow marks, the upper one 

 being a small subcostal dash, the lower two being prominent interspacial 

 elongated spots. Outside of these some specimens show signs of inter- 

 spacial white spots just within the hind margin. The submedian nervure is
