the lower end almost reaching the anterior mesotho- 
racic border. Superior appendages of g with an 
inferior row of denticles on the second fourth. 
12. pseudimitans 
Sides of thorax dark brown with three pale spots: two 
on inesepimeron placed obliquely one above the other, 
one on metepimeron; an antehumeral spot, not stripe, 
in front of the antealar sinus. Superior appendages 
of £ with a single, distinct, inferior tooth at a little 
more than half their length. . . 13. imitans 
Sides of thorax pale green or yellow with a brown 
stripe on the first and on the second lateral suture, 
the latter sending a branch down on the metasternum ; 
antehumeral stripes cuneiform, shorter in the $ than 
in the ? . Superior appendages of £ with an inferior 
row of denticles in the second fourth. 
Tip of inferior appendage of £ nearly as wide as 
the base, deeply bifid. . . 14. hemichlorct 
Tip of inferior appendage of £ one third as wide 
as the base, with a shallow excision. 15. cydippe. 
Of the above species 6. pumila Karsch, Berl. ent. zeit., vol. 33, 
p. 368, 1890, from Bahia, and 7. catharina Karsch, l. c., p. 366, 
from Theresopolis, S. Catharina, Brazil, have not been studied by 
me and are not further mentioned here. 
1. Macrothemis inequiunguis Calvert. PI. 1, fig. 2. Calvert, 
Proc. Cal. acad. sci., (2), vol. 4, p. 533, pi. 16, figs. 34, 40-45, 1895. 
A male in the Mus. Comp. Zool. from Chili by Thorey standing 
after the label in Dr. Hagen’s handwriting “ D. typographa* Hag.” 
(Dythemis typograplia Hagen, Proc. Bost. soc. nat. hist., vol. 18, p. 
86, 1875, no description) agrees with my description except in a 
few particulars which do not seem to be of specific value. These 
are: nasus with a small, brown, crescentic, central spot, labrum 
black with a small green spot at the middle of its base, the black on 
the lateral labial lobes leaves only their anterior margins yellowish, 
and the abdomen is more slender (width at 5 about .7 mm., at 7, 
2 mm.), which may, however, be due to the manner in which the 
specimen dried. The size is that of the smaller measurements given 
for inequiunguis. It may provisionally be regarded as a variety. 
Distribution. Mexico: Baja California in September and October; 
Tepic in November; Ecuador (Coll. C. C. Adams) ; Chili as above.
