. Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion). 
A fair series; the sexes do not appear to differ externally to any appreciable extent. 
4, Ochropepla dubia, sp. n. (Tab IV. figg. 7, 7 a, 6.) 
O. inequali latior, pronoto brunneo, tuberculis quibusdam minutis flavescentibus adsperso, fortiter punctato ; 
metopidio recto, haud inter humeros rotundato, lined dorsali valde elevata, ceteré fere pland, humeris 
obtuse prominulis, apice acuto paullo ultra abdomen producto; tegminibus hyalinis, clavo et corio ad 
basin fortiter punctatis ; pedibus brunneis. 
Rather larger and broader than O. inequalis, with the pronotum deep brown, sprinkled with a few minute 
yellowish tubercles ; metopidium flat, set at right angles to the rest of the pronotum, which is not 
gradually rounded from between the shoulders, as in the preceding species ; central dorsal line very strongly 
elevated and distinct, not sinuate if viewed sideways; there are, however, only slight traces of other 
dorsal lines; tegmina rather long, hyaline, with the veins brown ; legs brown. 
Long. 4, cum tegm. 52 millim.; lat. inter cornua 33 millim. 
Hab. Panama, Volcan de Chiriqui (Champion). 
This species, if viewed from above, bears a superficial resemblance to 0. inequalis, 
but may easily be distinguished by the characters above mentioned; the outer apical 
cell of the wings, however, is considerably larger than in the other specimens of 
Ochropepla which I have examined, and the tegmina are somewhat differently shaped, 
and their areas therefore somewhat dissimilar. JI am not sure that it may not have to 
be referred to another genus. ° 
POTNIA. 
Potnia, Stal, Berl. ent. Zeitschr. x. p. 388 (1866). 
The members of this genus may bé distinguished by having the pronotum armed with 
a porrect horn in front and the wings with four apical cells; the humeral prominences 
are blunt, but distinct. The species in size and shape rather closely resemble certain of 
the broader forms of Aconophora, from which they may at once be separated by the 
very short posterior tarsi, which are the distinguishing characteristic of the Hoplo- 
phorinee.

Stal (Kongl. Sv. Vet.-Ak. Handl. Band viii. 1, p. 37) cites Hoplophora granadensis 
as the type of his genus Enchotype (which closely resembles Potnia in appearance, and 
is distinguished by the wings having three instead of four apical cells); afterwards, 
however (v. Ofv. Vet.-Ak. Férh. xxvi. p. 267), on an examination of Signoret’s typical
