line on the primaries), on the outer margin close to the anal angle are two small black dots; underside of 
both wings uniform reddish-brown, with the darker lines very indistinct: head, thorax, and abdomen 
pale fawn-colour ; antenne and legs brown. Expanse 2? inches. 
Hab. Panama, Bugaba 800 to 1500 feet (Champion), Volcan de Chiriqui (Ribbe, in 
mus. Staudinger). 
This species is allied to O. lonomica, but at once distinguished from that insect by 
its differently coloured underside. The very worn example in Dr. Staudinger’s collection 
is rather greyer in colour, and the markings are not quite so distinct as in the specimens 
from Bugaba. 
4, Oxytenis beprea, sp.n. (Tab. XXI. figg. 3, 4.) 
Primaries and secondaries dark brown; primaries shaded with grey, a dark brown waved line crossing from 
the costal to the inner margin close to the base, a straight reddish-brown line crossing from the apex to 
the inner margin, beyond which is a row of lunate spots, and close to the outer margin a few indistinct 
dark brown dots; on the secondaries the markings form a continuation of those on the primaries, the 
submarginal row of dots being rather more distinct; underside pale yellowish fawn-colour, thickly 
irrorated with darker brown scales, the colour being brightest round the outer margins ; both wings with 
a submarginal dark brown line, this line having a row of dark brown marginal spots on the secondaries : 
head and thorax greyish-brown (abdomen wanting); antenne and legs brown, LExpanse 23 inches. 
Hab. Panama, Volcan de Chiriqui (R7bbe, in mus. Staudinger). 
I have only seen a single specimen of this insect. On the underside it is quite 
unlike any other species of the genus known to me.

Lonomia, Walker, Cat. v. p. 1191; ibid. vil. p. 1764. 
Walker places eleven species in this genus, all of which are from South America ; 
one of these extends northwards into our country, whence we now describe three 
others. 
1. Lonomia cynira.

Lonomia (?) cynira, Walk. Cat. vii. p. 1766°. 
Hab. Guatemana, Panima in Vera Paz (Champion).—Gu1ana, Surinam 12. 
A single male specimen of this species was sent from Vera Paz by Mr. Champion ; 
it agrees well with Cramer’s figure, and is the only one I have seen. 
2. Lonomia electra, sp.n. (Tab. XXI. figg. 73, 82.) 
Male. Primaries and secondaries uniform pale pinkish-brown, shaded with grey; primaries with two round 
white spots (placed one above the other) at the end of the cell, and beyond these a whitish line (bordered 
on the outer side with darker brown) crossing from the apex to the middle of the inner margin ; 
secondaries crossed above the middle and slightly nearest the base by a dark brown line; underside pale 
pinkish-grey, with the outer margins of both wings shaded with pale brown, two dark brown spots at the 
end of the cell of the primaries, and a dark brown spot on the costal margin of the secondaries near the apex :
