the apex to the anal angle of the primaries, the secondaries with a black spot at the end of the cell and 
several very narrow dark brown lines crossing below the middle; the fringe pale brown; the underside 
of both wings pale yellowish-fawn-colour: head, thorax, abdomen, palpi, antennz, and legs pale brown. 
Expanse +4, inch. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
Two specimens. This species resembles to some extent Megatomis remutcens, Feld. 
& Rogenh., but is altogether a smaller insect. 
8. Periphrage anyte, sp.n. (Tab. XX XVIII. figg. 28, 28a, ¢.) 
Male. Primaries and secondaries dark brown, crossed beyond the middle by two very distinct greyish-brown 
zigzag lines; the primaries with the costal margin pale brown from the base almost to the apex, a pale 
brown line crossing near the base, a greyish-brown spot at the end of the cell, another on the outer 
margin below the apex, and one at the anal angle; the marginal line of both wings black, the fringe 
brown ; the underside paler than the upperside and very similarly marked: head, thorax, palpi, antenne, 
and legs brown; the abdomen brown, banded with paler brown, the anus pale brown. Expanse 1,4, inch. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
Two examples, both males.

This genus was described, and the male and female figured, by Poey, who included 
in it a single species from Cuba. The male differs from the corresponding sex of 
nearly all other known genera of Deltoides in the great length of the palpi, and in these 
organs having a large brush-like tuft of hairs on the third joint. The Amazonian 
species placed by Felder and Rogenhofer in Mastigophorus (Reise der Novara, Lep. 
t. 120. fig. 11) cannot be included in it, this insect having tufted antenne, a character 
foreign to either sex of the present genus.

To judge from the large series of specimens before me, this variable insect is common 
in Costa Rica and the State of Panama. Felder and Rogenhofer’s figure is paler in 
colour than most of the Central-American examples. 
The female is very similar to the male, but has quite small palpi.
