Hab. Guatema.a, Cerro Zunil 4000 feet ( Champion); Costa Rica, Rio Sucio (Rogers) ;

One worn specimen from each locality. 
4, Hypenaria (?) umbrigens, sp. n. (Tab. XXXIV. fig. 1.) 
Male, Primaries and secondaries reddish-brown; both wings crossed by a central dark reddish-brown line 
shaded on the inner side with pinkish-brown, and with a submarginal row of minute reddish-brown 
spots ; the primaries with a reddish line near the base, an indistinct reddish-brown mark at the end of 
the cell, and the costal margin blackish at the base ; the underside uniformly brown, with a darker brown 
line crossing both wings; the fringe dark reddish-brown: head and collar blackish-brown ; the thorax, 
tegule, abdomen, antenne, palpi, and legs dark brown; the front legs furnished with a large brush of 
reddish-brown hairs. The females similarly marked to the males, but (in the three specimens before me) 
much paler in colour. Expanse 23 inches, 
Hab. Panama, Bugaba 800 to 1500 feet, Volcan de Chiriqui (Champion). 
A very variable species, no two examples of which are exactly alike. The one 
figured is a dark form from the Volcan de Chiriqui. ‘There is a specimen of this insect 
in the National Museum labelled with a ticket in Walker’s handwriting, which I am 
unable to decipher with any certainty; but I believe it to be “ wmbrigens,’ though, so 
far as I am aware, it has not been described under that name.

Varia, Walker, Journ. Linn. Soc., Zool. ix. p. 190. 
A well-marked genus in no way resembling Thermesia, with which Guénée associated 
it. It contains a few species from Central or South America or the Antilles.

A common insect in our region. It is exceedingly variable in colour, both on the 
upper and undersides; and is not at all constant in any one locality. One or two 
specimens from Guatemala have quite a green shade on the wings. Plaxia sera, Walk., 
is nothing but a dark form of the same species.
