series. From within our limits we possess five male specimens only; the sexes are 

 remarkably different. 



Hesperia itea, Swainson, is the nearest allied form we are acquainted with. We 

 figure the fore wing of a male of 0. cynisca, also the genitalia, for which see

2. Orses iricolor, sp. n. (Tab. CV. figg. 7, 8, <s .) 



Alis fuscis, stigmate grisescente, anticis macula magna in cellula et duabus minoribus inter ramos medianos 

 flavo-hyalinis, ad basin et posticis fere omnino viridi-caeruleo tinctis : snbtus fuscis, purpureo lavatis, 

 anticis area mediana obscuriore, maculis ut supra, in costa maculam cellularem attingente et apici propiore, 

 flavo notatis; posticis fasciis duabus obliquis subparallelibus, una a margine costali juxta apicem ad 

 marginem externum, altera basi propiore angulum analem versus, extendentibus, et margine interno ipso, 

 sulphureis ; capite et corpore supra viridibus, cseruleo tinctis ; ciliis ad angulum analem anticarum, et 

 posticis omnino, griseis ; tibiis rufis. 



$ ignota. 



Hdb. Panama, Chiriqui (mus. Standinger), 



Of this very fine species there is a single male example in Dr. Staudinger's collection. 

 It is allied to 0. cynisca (Swains.), and has the yellow spots of the primaries similarly 

 shaped and placed, but it may easily be separated from that species by the greenish- 

 blue sheen on the upperside of the wings and by the pale longitudinal stripes on the 

 underside of the secondaries; the secondaries, too, are more produced at the anal 

 angle. 



THRACIDES. 



Thracides, Hiibner, Verz. bek. Schmett. p. 105 (1816) (part.); Watson, P. Z. S. 1893, p. 122. 



The type of Thracides^ Papilio phtdon, Cram., has a very narrow, oblique, inter- 

 rupted brand on the primaries in the male, but in several other species which we 

 include here this is absent. They are all Tropical-American forms of laro-e size, 

 and many of them have the base of the wings and the upperside of the body shot 

 with blue. 



The antennae are very long, nearly reaching the end of the cell, and have an 

 elongate club, terminating in a long crook. The palpi are densely clothed with 

 scales ; the third joint is very short and almost concealed. The primaries are elongate 

 and somewhat pointed; the cell is nearly two-thirds the length of the costa; the 

 discocellulars are very oblique, the upper one more than twice the length of the lower, 

 the latter a little shorter than the third median segment; the first branch arises 

 considerably before the middle of the median nervure, the second near the lower angle 

 of the cell. The secondaries are produced at the anal angle ; the discocellulars are 

 very oblique, the lower one quite distinct. The body is very robust. The middle 

 tibiae are spined in T. phidon, unarmed in T. longirostris and others ; the hind tibiae 

 have two pairs of spurs. The primaries of the males of T. phidon and T. aurifer have
