G. — PAriLIO LACANDONES. 



(^ . Expans. 3" 8'". Fore-wing costa slightly arched towards 

 the tip, apex produced, outer margin slightly incurved. Hind-wing 

 apex produced and acute, furnished with a long linear tail. Above : 

 brown, disk of both wings occupied by a common triangular ochreous 

 spot, the anterior side of which, parallel to costa, is irregular towards 

 the apical angle, forming two obtuse lobes projecting into the cell, there 

 are also three ochreous spots on the fore-wing costa, and a straight line 

 near apex of wing ; the hind- wing has a series of ochreous sub-marginal 

 lines between apex and base of tail, followed from tail to apex by a row of 

 gi-ey circumflexes, the anal angle having an oblique red line ; the tail 

 brown, tipped with yellow. Beneath : the same, except that there is a 

 broken red line crossing the hind-wing within the brown border. 

 Antennae black, 



Guatemala, province of Vera Paz. Resembles P. Leucaspis (Godart) 

 of New Granada, but is smaller, the discal triangular spot is of a 

 clearer ochreous hue, and the hind-wing has a remarkably acute apical 

 angle, besides having a row of yellow sub-marginal lines, absent from 

 P. Leucaspis. 



7. — PAPILIO GLAUCOLAUS. 



Size and disposition of black markings same as P. Protesilaus, 

 but differs in the greenish-white tint of the ground colour of the wings 

 both above and beneath, in which it resembles P. Autosilaus (Bates), of 

 the Upper Amazons, rather than the typical form and varieties of P. 

 Protesilaus. The only other points of distinction from P. Protesilaus 

 are the narrower transparent space between the black lines of apical 

 border of fore-wings, and the straightness of the inner black outer 

 border of the hind-wings enclosing the pale lunules. 



Eastern side of Isthmus of Panama. Numerous specimens of tliis 

 form were obtained with an equal number of a fine large variety of P. 

 Protesilaus* in the same locality on the Isthmus of Panama. A s no 

 intermediate form occurred, the conclusion is unavoidable that oin- P. 

 Glaucolaus maintains itself here as a distinct species from its near r(!la- 

 tive P. Profesilmis. 



8, — PAPILIO SALVINI.

 duced and pointed, outer border inciu-ved. Hind-wing apex obtuse, 

 outer margin straight from apex to the tooth preceding the tail ; tail
