Telebasis isthmica (p. 118). 
The mid-dorsal thoracic stripe is a little narrower in these supplementary specimens than in the types. 
To the localities given, add:—Costa Rica, Bebedero (Underwood: 1 3), Santa 
Clara (Tristan: 1 3). 
Telebasis salva (p. 119).

In one only of the supplementary specimens, a male from Gualan, are the submedian dorsal thoracic bronze 
stripes hardly widened superiorly, and in it the apex of the projecting angle on each side is still present 
as an isolated bronze dot. In one male from Jesus Maria these stripes are not at all widened superiorly 
and there are no vestigial dots. 
To the localities given, add :—Mexico, Bafios de Santa Rosalia [2 ¢ ] in Chihuahua, 
Yurecuaro [2 ¢ | in Michoacan, Ocotlan [2 ¢,1 9 ]in Jalisco (Calvert, coll. P. P. C.), 
Aguascalientes (Howard, U.S. N.M.: 1 3); Guatemata, Los Amates [4 ¢ ], Gualan 
[29 ¢, 1 2], Escuintla [1 3], Santa Lucia [1 ¢] (Williamson, Deam, Hine, colls. 
Wilmsn., O. S. U.); Costa Rica, Jesus Maria (Biolley, colls. A. N. S8., Wlimsn.: 2 3, 
1 2); Panama, Colon (Howland, coll. Needham: 1 3). 
This species was very abundant at Ocotlan on August 29,1906. The eyes of the 
adult male are bright scarlet in life.

Mr. Williamson noted of a female at Los Amates: ‘Thoracic colours light sea-green and bright light rust 
or almost orange.” The sea-green appears to include, in some of both sexes, an antehumeral stripe 
(which has faded in the specimens previously recorded) not reaching to the front wing-bases, its upper 
end a little widened and cut straight across, and some of the sides of the thorax. The effects of 
dessication on the thoracic colours are very varied, however. 
Of the twenty-five additional females here recorded, all but three (Los Amates) have the vulvar spine present. 
In those three I am unable to determine whether its absence is due to breakage or not, but they have the 
abdomen otherwise entire. 
To the localities given, add:—GuatemaLa, Morales [3 3, 2 9], Los Amates 
(9 ¢, 8 2] (Hine, O. S. U.) [16 g, 14 9]; Honpuras, Puerto Cortez [1 3]

Chinandega °. 
Mr. Williamson noted of this species at Los Amates, Jan. 18, 1905: ‘In shaded 
bogs along railroad track below Los Amates. Very slow and sluggish, always in 
shade and in one certain species of sedge, though a grass very similar in style grew in 
proximity. Observed between 2 and 5 P.M.”
