PACHYDIA. 137 
with some black dots close to the apex, which is slightly irrorated with greyish scales, the fringe pale 
brown ; the secondaries crossed from the costal to the inner margin by three curved dark brown lines— 
the first, nearest the base, darker than the others, the second about the middle and very indistinct, the 
third submarginal and broken up into spots,—the fringe pale brown ; the underside pale brown, without 
markings: head, thorax, abdomen, and legs pale brown, the antenne dark brown.—Female. Darker in 
colour and with the lines more indistinct; the secondaries crossed from the costal to the inner margin 
by a submarginal reddish-brown band, which is much more distinct in some specimens than in others. 
Expanse, ¢ 1,4, 914 inch. 
Hab. Guatema.a, Las Mercedes 3000 feet, Cerro Zunil 4000 to 5000 feet, Volcan 
de Atitlan 2500 to 3500 feet, San Gerénimo (Champion). 
Numerons examples, including both sexes, ’ 
6. Pachydia cercyon, sp.n. (Tab. LIV. fig. 3, ¢.) 
Male. Primaries and secondaries yellowish-fawn-colour, paler at the base, each crossed by two very faint 
narrow brownish lines, and with a white dot edged with black at the end of the cell; the primaries with 
the costal margin and a spot at the apex irrorated with blackish-grey scales; the fringe pale greyish- 
brown; the underside pale whitish-fawn-colour, broadly bordered with pale brown: head, thorax, 
abdomen, and legs fawn-colour, the antenne dark grey, the anal tuft pale fawn-colour. Expanse 1 inch. 
Hab. Mexico, Presidio (forrer). 
One specimen. Very distinct from any other species known to me. 
' 7, Pachydia cermala, sp. n. (Tab. LIV. figg. 4,3; 5,9.) 
Male. Primaries and secondaries pale brown, each crossed by three waved darker brown lines, their marginal 
lines with black points; the primaries with a very distinct black spot at the end of the cell; the fringe 
dark brown ; the underside pale greyish-brown, broadly bordered with darker brown: head, thorax, and 
abdomen pale brown, the antennz and palpi blackish-brown, the legs and underside of the abdomen pale 
greyish-brown.—Female. Very similar to the male, but with a white spot at the end of the cell on the 
secondaries. Expanse, ¢1j, 21 inch. 
Hab. Mexico, Coatepec (coll. Schaus), Jalapa (M. Trujillo); Guatemata, Volcan de 
Atitlan 2500 to 3500 feet (Champion); Costa Rica, Volcan de Irazu 6000 feet (Rogers) ; 
Panama, Volcan de Chiriqui 2000 to 3000 feet (Champion). 
I have a large series of this species before me. Both sexes show a considerable 
amount of variation in the distinctness of the whitish spot on the secondaries; the 
specimen from Coatepec in Mr. Schaus’s collection has this spot larger than in any 
other I have seen. We figure a pair from the Volcan de Atitlan. 
8. Pachydia oroanda, sp.n. (Tab. LIV. figg. 6, 7, 3.) 
Male. Primaries and secondaries pale fawn-colour, crossed by two indistinct slightly darker waved lines, and 
thickly irrorated with small black scales ; the fringe fawn-colour; the underside whitish-brown, with 
the outer margins bordered with darker brown: head, thorax, and abdomen pale fawn-colour, the 
antenne blackish-grey, the legs pale brown.—Female very similar to the male. Expanse, g 14, 21,4 
inch, . . . 
Hab. Mexico, Jalapa (coll. Schaus); GuateMaa, Totonicapam 8500 to 10,500 feet, 
San Isidro 1600 feet, Volcan de Atitlan 2500 to 3500 feet (Champion). 
We figure two males from San Isidro, one of them (fig. 7) being a very distinct 
variety.
