ACROLOPHUS.—SARROTHRIPUS. 401 
This species invariably possesses a few scattered single white scales, tipped with 
black—these are very irregularly distributed, but usually.to be found, even in worn 
specimens, above and below the fold. These white scales occur in the Type, as also 
in seven other specimens examined, including a pale variety from Jalapa (2 4740 
Mus. Wlsm.) in which the dark blotches are reduced to small, but somewhat clearly 
defined spots, the one nearest the base being absent. 
62. Acrolophus laetifica, sp. n., Drnt. 
Antennae serrate; fuscous. Palpi, ¢ strongly recurved, overarching to the middle of the thorax, each joint 
separately tufted ; ochreous, shaded with fuscous on the outer side of each joint; 9 projecting more ~ 
than the length of the head beyond it, cinereous, or ochreous, outwardly shaded with fuscous. Head 
ochreous, mixed with fuscous. Thorax fuscous. Forewings elongate; ochreous, shaded with fuscous ; 
the fuscous spots along the costa are more or less distinctly continued across the wing as inwardly oblique 
strigulae ; the usual three spots are traceable, one at about one-third, a second at the end of the cell, 
and a third plical, but these are connected by a broad fuscous suffusion, which, starting from the first. 
discal, occupies the lower half of the cell and expands to the tornus; the ochreous ground-colour is most 
noticeable along the dorsum, and toward the apex; cilia ochreous, shaded with fuscous. Aap al, 25- 
34 mm. Hindwings fuscous; cilia with a darker line near their base. -Abdomen fuscous: genitalia, 
uncus double, bent over, the points slender and slightly diverging, not reaching to the ends of the rather 
slender claspers which are strongly arched upward from the base, their upper margin being bent inward 
along the descending curve and forming an angle with the outer edge. which is somewhat excavate.

The 9 is larger and darker than the ¢, and the spots are usually not very notice- 
able, but in a single pale ochreous 2 (66938, Atoyac) the strigulation is slight and 
the spots are more conspicuous than in the ¢ —FW: 8-9 are stalked in both sexes.
