The jtreseiit species is easily distiiifrnished from uncheinolus iu tlie c? sex by 

 the first, segment of the liiiuUarsiis not being broadly scaled ; the ? ? reqnire more 

 careful comparison, but the dark outer surface of the foretibia aud the less extended 

 white hinder edge of the forewing, as well as the prolonged subapical costal patch of 

 the same wing, will be sufHcieut to recognise triangulum.

c? ? . The insects united here under one species have partly been considered 

 specifically distinct. As these forms are clearly geograjjhical representatives of 

 one another, and differ only in the lighter or deeper shades of the pattern, which 

 is otherwise essentially the same, the differences being, besides, bridged over to 

 a certain extent by intergi'aduate individuals, we do not see any reason for treating 

 any of the insects as distinct. 



Linne's description is based solely on Drury's figures, which ai'e said by 

 Uniry to be taken from Jamaica specimens. The figure of the c? agrees fairly 

 well with our Jamaica S, showing especially the reddish tint peculiar to the 

 Jamaica tj, while the figure of the ? is decidedly incorrect. It is altogether too 

 green, and does not agree at all with Drury's own description, which fits Jamaica 

 examples. The figure, resembling to a certain extent the North American form 

 pandorus of satellitia, misled Messrs. Grote and Robinson to consider the Nearctic 

 form to be the true satellitia. 



^Vhite spot of jjalpus and s})ot behind eye conspicuous. Forewing with 

 black double stigma, deeper in tint than the lines ; hinder edge more or less 

 pinkish. Under surface not red ; but disc of forewing often russet-tawny. First 

 segment of hiudtarsus shorter than tibia in (J, only as long as segments 'Z and 

 3 together ; in ? as long as tibia. 



cJ. Tenth tergite pointed (I'l. XLIV. f. 5). Clasj)er large, dorsal margin 

 slightly convex ; no patch of bristles on inner surface ; harpe ending in a long, 

 evenly curved hook which varies iu length (PI. XLVIII. f. 2). Penis-sheath stout, 

 process pointed but not slender, about twice as long as the sheath is broad. 

 (PI. LIV. f. 27). 



Larva green, sometimes changing to brown shortly before pupating ; with 

 five or six white side-spots ; fine black dots, especially on fburtii segment. — 

 Food-plants : Vitis ; Ampelopsis.
