Male. Primaries pale pinkish-brown, dark reddish-brown towards the base, with a brownish-black band 
crossing about the middle—widest at the costal margin, but becoming quite narrow and divided in the 
centre, then widening again at the inner margin,—this band edged on each side with a narrow white line, 
a submarginal fine white line extending from the costal margin near the apex to the anal angle, and a 
dark brown spot at the anal angle, the fringe greyish-brown ; secondaries greyish-white, with the inner 
margin broadly bordered with blackish-brown, the outer margin dusky, the anal angle streaked with 
pinkish-brown, the fringe greyish-brown ; the underside dark grey, with a few black dots on both wings : 
head and antenne black, the thorax pinkish-brown, black in front; the abdomen blackish-brown, with the 
base pinkish-brown ; the legs blackish-brown.—Female. Very similar tothe male, but not quite so bright 
in colour, and with the band on the primaries slightly narrower. Expanse 73; inch. 
Hab. Muxico, Amula in Guerrero 6000 feet (1. H. Smith). 
Two specimens. 
3. Eupithecia orilochia, sp. n. (Tab. LIV. fig. 22, .) 
Male. Primaries and secondaries very pale fawn-colour, slightly irrorated with fine reddish-brown scales ; the 
primaries with two dark brown spots on the costal margin and a small spot at the end of the cell; the 
secondaries crossed about halfway from the inner margin by a rather wide reddish-brown band and with 
a reddish-brown streak at the anal angle, the fringe fawn-colour, with a reddish-brown dot at the end 
of each vein; the underside paler than above, with the markings less distinct: head, thorax, antenne, and 
legs fawn-colour, the abdomen reddish-brown irrorated with fawn-coloured scales, the anal tuft pale 
fawn-colour.— Female very similar to the male. Hxpanse # inch.

4. Eupithecia orsetilla, sp.n. (Tab. LIV. fig. 23, ¢ .) 
Alule. Primaries dark silky brown, crossed from the costal to the inner margin by several very indistinct pale 
brown waved lines, and with a very narrow submarginal waved line extending from the apex to the anal 
angle and a black dot at the end of the cell; secondaries a little lighter than the primaries, mottled with 
pale brown near the anal angle; the underside paler than above, and with the lines slightly more distinct : 
head, antenne, thorax, abdomen, and legs brown.—Female generally paler than the male. Expanse 
<5 inch. 
Hab. Mexico, Amula in Guerrero 6000 feet, Teapa in Tabasco (H. H. Smuth) ; 
GuatemaLA, Volcan de Atitlan 2500 to 3500 feet (Champion); Costa Rica, Volcan 
de Irazu 6000 to 7000 feet (Rogers). 
We figure a specimen from Teapa. 
5. Hupithecia certissa, sp.n. (Tab. LIV. figg. 24,3; 25, 2 .)

faint lines, and with a submarginal pale waved line extending from the apex to the anal angle, a small dot 
at the end of the cell and the marginal line black, the fringe grey; the secondaries very similarly marked, 
the lines being continued across from the costal to the inner margin; the underside with the lines even 
fainter than above: head, thorax, antenna, and legs pale grey, the abdomen darker grey.—Female darker
