amount of variation displayed by this species at one locality. No other species of Brechmorhoga was 
taken at Gualan. Labrum yellow, only in a few males a brown dot on each side. Pale spot on each side 
of the dorsum of segment 7 slightly more than half as wide as that side on which it lies, Wings brownish- 
yellow or brownish at base to the submedian cross-vein or not so far, in both sexes; in the rest of their 
area, slightly yellowish or only so between the triangle and stigma (g); pale yellow throughout, or only 
so between the triangle and stigma, or brownish-yellow throughout, or uncoloured except for the apex 
of the front wing, which is brownish in as far as the third or fourth postcubital, or pale yellowish 
throughout with the apex of the front wing brownish as just described (2). I am not able to correlate 
these differences in wing-colouring with age. Front wings: post-triangular rows to level of nodus 2, 3,

Mr. Williamson made these notes:—‘ Gualan. Jan. 14,1905. Flies high and is 
very wary during the day. All specimens taken about sundown as they hunted resting- 
places about brush, usually the thickest places—brush covered densely with Con- 
volvulus.’ “Kl Rancho, Jan. 25,1905. Flies like a Corduline and, like Macromia, 
alights on the underside of twigs, abdomen hanging. The above remarks apply also to 
habits of same species as observed at Gualan.” 
Intermediate between precox and mendaxt—A male each from Huatusco (coll. 
Adams) and Coatepec (Barrett, coll. P. P. C.) in Vera Cruz, and three males from 
Cuernavaca (Barrett, colls. Adams, P. P. C.), October, while aliied to precox are not 
typical. They have the apex of the hamule thicker and not so acute, two and three 
rows alternating in the area between A, and the margin of the hind wings, labrum 
chiefly black, only its base pale: abdomen 37-41 mm.; hind wing 35-37 mm., its 
width at arculus 10—11, at nodus 10-10°5 mm.
