38 HETEROCERA. 
1. Triprocris aversus. 
Triprocris aversus, H, Edwards, Papilio, iv. p. 13°. 
Hab. Mexico, State of Vera Cruz (Schaus 1). 
Unknown to me. 
PSEUDOPROCRIS, gen. nov. 
Allied to the preceding genus, much about the same size, but with the primaries rather more rounded at the 
apex ; the neuration nearly the same, excepting that the cell is slightly longer; secondaries same as 
Procris. Head small; the palpi very minute. Antenne very long, quite two thirds the length of the 
wing, not pectinated, but quite thick, and almost clubbed at the end. Thorax and abdomen thick ; the 
abdomen extending about one third of its length beyond the secondaries. Legs moderately stout. 
1. Pseudoprocris gracilis, sp.n. (Tab. VI. fig. 3.) 
Primaries greenish, shot with black ; secondaries hyaline at the base, and in the middle the costal and outer 
margin brownish green; the underside of both primaries and secondaries glossy bluish green: head, 
thorax, and abdomen green, very bright on the upper side; antenne bright glossy green, the tip black ; 
legs greenish black. LExpanse 1,), inch. 
Hab. Mexico, Jalapa (Hége), Milpas 5900 feet (Horrer). 
This and the following species differ from all the described forms known to me by 
their extremely long antenne. The specimen from Milpas is much browner in colour ; 
but this may arise from its being a very worn specimen. 
2. Pseudoprocris dolosa, sp. n. 
Primaries semitransparent black, the costal, outer, and inner margins black ; secondaries hyaline, excepting the 
costa and apex, which are dusky: head, antenna, thorax, and legs black; abdomen wanting. Expanse 
1 inch. . 
Hab. Guatrema.a, Calderas (Champion). 
A single example, in very poor condition, has been received of this insect. It 
resembles in colour Procris thyesta; but the antenne at once show that it is more 
closely allied to Pseudoprocris gracilis. 
SERYDA. 
Seryda, Walker, Cat. vii. p. 1598. 
Walker founded this genus for the reception of a species sent by Mr. Bates from the 
Amazons. 
1. Seryda megalops, sp. n. (Tab. VI. fig. 5.) 
Primaries and secondaries uniform semitransparent greenish black, slightly darker on the costal and outer 
margins of the primaries: head, thorax, and abdomen black, glossed with green; antennwy very deeply 
pectinated, rather long, being quite two thirds the length of the wing; legs black; a tuft of hair on each 
side of the anus extending some way beyond, forming a small brush-like appendage. Expanse 1? inch. 
Hab. GouateMata, Capetillo (Champion). 
Unly a single example of this very distinct insect was sent. I have placed it in this 
genus with considerable hesitation, not having seen Walker’s type; it agrees well in all 
respects with his description, excepting that it is a very much larger species.
