VETTIUS.— CCELIADES. 591 



Through the kindness of Dr. Staudinger we are able to include this species in 

 our fauna, as he has lent us a pair from Panama, and he has also sent us for 

 examination the type ( $ ) of Cobalus pica, Herrich-Schaffer. V. lafresnayi is a very 

 close ally of V. triangularis (Hiibn.), from which, however, it differs in its larger size 

 and in having one or two hyaline spots in the cell. It may be separated at once from 

 V. phyllus by the very dissimilar coloration of the underside of the secondaries. For 

 the genitalia of the male, see Tab. CII. fig. 32. 



CCELIADES. 



Cceliades, Hiibner, Verz. bek. Schmett. p. 106 (1816) ; Scudder, Proc. Am. Ac. Sci. x. p. 145 (1875). 



We follow Scudder in taking Papilio dubius, Cram. (=Phlebodes virga, Butl.), as 

 the type of this genus, which was not identified by Watson, and it will also include 

 Hesperia fiscella, Hew.; both are from Tropical America, the last-mentioned entering 

 our limits. It seems best placed near Carystus, from which it differs in having a very 

 conspicuous brand on the primaries of the male ; the antennae are also more elongate 

 and have a very long crook, and the lower discocellular of the secondaries is longer and 

 much more oblique. In both species the primaries have a steely lustre on their outer 

 half (not visible in Carystus), and the secondaries have a narrow, transverse, sharply 

 defined, whitish band on the underside, this being sometimes very much reduced in 

 C. dubius. The brand is not unlike that of the species of the genus Eutychide, except 

 that the piece beneath the first median branch is absent. 



The antennae are very elongate, reaching nearly as far as the end of the cell, and 

 have a slender club, terminating in a very long crook. The palpi have the third 

 joint very short and almost concealed. The primaries are elongate, slightly concave on 

 the outer margin, rounded at the tip ; the costa is arched at the base, straight towards 

 the apex ; the cell is less than two-thirds the length of the costa ; the discocellulars 

 are strongly oblique, the lower one much shorter than the upper, the latter of the same 

 length as the third median segment ; the lower radial is slightly depressed at the base ; 

 the first branch arises slightly before the middle of the median nervure, the second not 

 far from the lower angle of the cell. The secondaries are feebly lobed at the anal 

 angle ; the discocellulars are faint, the lower one very oblique and three times the 

 length of the upper. The body is rather slender. The legs are elongate ; the middle 

 tibia? are without spines, and the hind tibiae have two pairs of very long spurs. The 

 primaries of the male (Tab. CII. fig. 35) have a brand formed of three stout pieces : 

 (1) a short longitudinal streak beneath the second median segment ; (2) a similar but 

 longer streak above the first median branch at some distance from its point of origin 

 (these two pieces more extended towards the base of the wing and forming a long 

 >-shaped mark in C.jiscella, the upper one sometimes absent in C. dubius) ; (3) a still 

 longer streak above the submedian nervure, extending to a third or more of its length.
