Central-American specimens, as well as others from Ecuador in my own collection, 
are slightly smaller and paler than Snellen’s figure. The particular locality for 
M. divergentata is not mentioned by Snellen!; the species is included amongst others 
described by him from New Granada, St. Thomas, and Jamaica.

THAMNONOMA. 
Thamnonoma, Lederer, Verh. zool.-bot. Ges. Wien, ii. p. 232 (1853) ; Packard, in Report of the 
U.S. Geol. Surv. of the Territ. x. p. 249, t. 3. figg. 2, 2a, b (1876) (neuration). 
This genus is closely allied to Lozogramma, Steph., from which it may at once be 
distinguished by the pectinated antenne of the males. Packard includes ten species 
from North America in this genus, and four are here added from our region. 
1. Thamnonoma imitata, sp.n. (Tab. LIII. figg. 20,3; 21,9.) 
Male. Primaries and secondaries very pale brownish-grey, slightly darker along the costal and outer margins ; 
the primaries with two fine brown lines crossing from the costal to the inner margin—the first near the 
base, the second beyond the middle,—and a marginal line with black points, the fringe greyish-brown ; 
the secondaries without markings ; the underside yellowish-brown, with the lines very indistinctly marked. 
—The female very similar to the male, but generally larger and with a black spot at the end of the cell on 
both wings, the secondaries crossed about the middle with dark brownish lines ; the underside paler than 
in the male, and with the lines crossing the wings more distinct. Expanse, ¢ 1,%,, 914 inch. 
Hab. Mexico, Amecameca (f. D. G.), Las Vigas (coll. Schaus) ; Guatemata, Quiché 
Mountains 7000 to 9000 feet (Champion). 
This species resembles the European Lozogramma petraria, Esp. Mr. Godman’s 
specimens were captured in April 1888. 
2. Thamnonoma olympusa, sp. n. (Tab. LIII. fig. 22, 3.) 
Male. Primaries dark grey shaded with brown, crossed from the costal to the inner margin by three dark 
brown liries--the first and second edged with pale yellow, the third submarginal and less distinct than
