overflows into some of the subcostal cells. Carmine at the base of the hind wings reaching from the 
subcosta to the postcosta, and outward in the subcostal space four cells beyond the quadrilateral, but 
elsewhere to one cell less than the apex of the quadrilateral. Reticulation in these spots red, elsewhere 
black. About 9 median cross-veins, 7-9 in the quadrilateral, 22 antecubitals, and three rows of postcostal 
cells on the front wings. 
In the young male all the black is pale brown, and no red is visible on the wings, although the reticulation is 
very pale in the areas in which the spots are to appear. 
Abdomen, ¢, 39-41; hind wing, 3, 28-30°5 mm. Q unknown. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith: 1 3); GUATEMALA, Cahabon in 
Vera Paz (Champion: 1 3). 
The general shape of the appendages and the apical red spot on the hind wings 
only are suggestive of the South-American H. rosea and H. dominula ; but H. pilula 
is distinguished from them and from other species by the capitate form of the inferior 
appendages, the simpler reticulation of the postcostal area, and, although of minor 
importance, the presence of a pterostigma. ‘The specific name proposed has reference 
to the shape of the enlarged tip of the inferior appendages.
