terminations of the nodal and subnodal sectors, where there is a dark isolated spot. Extremes a and 6 are 
connected by individuals in which there is a narrower or wider stripe of dark colour extending along each 
side of the nodal sector from the transverse band to the hind margin. A connecting form near extreme 6 
is shown in Mr. Kirby’s figure*, The clear areas of the apex are always greater on the hind wing than 
on the front. 
The series from Plan del Rio is similar to that from Gualan in this variation, but does not quite reach 
extreme b. 
The paler-coloured parts of the basal half of the hind wings of Mr. Kirby’s figure ® are occasionally perfectly 
clear (Gualan, Zacapa, R. Papagaio, &c.); although these individuals are not mature, I am not sure that 
youth alone will account for this condition. Intermediate conditions with these parts only slightly 
coloured are presented by males from Tocoy, Atoyac, Victoria, &c. 
2. Clear area at apex of wings always greater than in the g; the dark stripe along the nodal sector is present 
in all but one (Acapulco) of these females, and extends proximad toward, but never reaches, the broad 
dark transverse band of the wings. This latter band, lying between the nodus and the stigma, varies in 
width; it is connected with the dark area of the anal “angle” of the hind wings in only one of the 
Gualan series, but the connection exists in other localities (Altamira, 8. José del Cabo, Dos Arroyos, 
Acapulco), A connection between the dark area of the triangle and that of the anal “angle” of the hind 
wings may or may not exist, even in the same locality (Gualan). The greater or less extension of dark 
colouring on the wings is not correlated with their size. 
¢ 2. In the post-triangular field of the front wing, out to the level of the origin of the subnodal sector, the 
males have, for at least part of the way, 4 rows of cells, most females not more than 3 rows. 
Measurements of Lower-Culifornian specimens have been given elsewhere‘; those of material from the Mexican 
mainland and Central America are slightly lower:—Abdomen, g 22-28, 2 21:5-25; hind wing, 
3 29-37, 2 29-35 mm.; the lowest figures are mostly from Gualan, the highest from Plan del Rio.

Mr. Williamson * made the following notes in the field :—‘ Between El Rancho and 
Sanarate, Jan. 27,1905. This species and Pantala flavescens were most often observed 
along the trail, often far from water, amidst dust and in the hot sunshine. ‘This 
species much rarer though than Pantala flavescens.” ‘‘Gualan, Jan. 11, 1905. 
* Mr. Williamson’s itinerary has been published in Ent, News, xvi, pp, 299-306 (1905), and includes, in 
part, those of Messrs. Hine, Deam, and Miller.
