(from base to level of the discoidal triangle), which are almost clear, or (6) the blackish-brown only 
begins at the seventh antecubital, i. ¢. beyond the discoidal triangle (Presidio de Mazatlan), and extends 
outward as above *. Between a and 6. all intermediates exist, even the same locality (S. Gerénimo, 
Caché) presenting much variation in this respect. The hind wings offer slighter differences, being 
usually entirely blackish-brown from base to about midway between nodus and stigma, but a male from 
Presidio de Mazatlan has a fairly clear area between the proximal subbasal sector (A, of C. & N.) and 
the anal angle, except that the brown remains alongside the membranule ; the other two males from 
this locality connect the first-mentioned with the usual style of colouring. Immature males and 
immature homcochromatic females have the. wings yellowish from base to midway between nodus 
and stigma. . 
The heterochromatic females closely resemble heterochromatic females of H. umbrata, the only difference being 
the possession of two rows of cells (instead of one) between the short sector and the supplementary sector 
next below, and it is possible that the two may have been confused in the past. They vary just as the 
corresponding females of uwmbrata do in the extent of yellow at the base, and of brown at the tips, 
of the wings. The parallelism is carried still farther in that old, more or less pruinose, heterochromatic 
females of funerea, by a darkening of the yellow at the wing-bases into brown, closely resemble that 
form of umbrata which I originally described as montezuma (see page 252). In this “ montezumoid ” stage 
of colouring of funerea the deep brown at the base of the hind wings extends outward to the first 
antecubital and origin of A,, or to the second antecubital, arculus, and discoidal triangle, and backward 
almost to the hind margin. 
Dimensions.— Abdomen, ¢ 24-84, 9 23°5-32°5; hind wing, ¢ 26-36, 2 25-36; costal edge of stigma, 
front wing, 3°5-5°5 mm. The smallest individuals, from San Gerénimo (¢) and El Reposo (¢), have 
the two rows of cells between the short sector and the supplementary sector next below reduced to 
one double cell in three (El Reposo) or two (S. Gerénimo) of the wings. The largest individuals are 
those from Stanford University, Guadalajara and Tepic. The range in size from San Geronimo is: 
abdomen, ¢ 24-29, 9 25-31; hind wing, ¢ 26°5-33'5, 9 27-335 mm.

* A female taken at Atoyac in May, apparently not yet mature, is still more extreme than (6), as its wings 
are crossed by a band whose distal edge is midway between nodus and stigma, while the ill-defined proximal 
edge is at the level of the penultimate (front wing), or antepenultimate (hind wing), antecubital; proximal 
to this band, however, the wings are not so clear as distal to it.
