Its robust form suggests Paltothemis lineatipes Karsch. 
1 £ in Mas. Comp. Zool. labeled “P. Br.” & “ L. constricta” in 
Selys’s handwriting. Hagen l. c. gives the locality as Brazil. 
I do not know Dythemis multipunctata Kirby, Ann. mag. nat. 
hist., (6), vol. 14, p. 265, 1894, from the West Indies. 
None of the undescribed species listed under Dythemis by Hagen 
in 1875, other than those mentioned above, belong to this genus as 
here defined. 
^2. Paltothemis Karsch. 
Karsch, Berl. ent. zeit., vol. 38, p. 362, 1890. 
Only one species is known :— 
1. P. lineatipes Karsch. PI. 1, figs. 1, 8, 9. Karsch, l. c., 
p. 363, 1890. 
Synonym: Dythemis russata (Hagen MS.). Calvert, Proc. Cal. 
acad. sci., (2), vol. 4, p. 526, pi. 16, figs. 46-49, 1895. 
Distribution : Karsch’s type, which I have studied, is from Brazil, 
those of russata from Baja California, in September and October, 
and Arizona. I saw this species in the K. k. naturhistorisches 
Hofmuseum at Vienna labeled “Merida,” and a male at Cambridge 
from Texas. ^ 
3. Brechmorhoga Kirby. 
Kirby, Ann. mag. nat. hist., (6), vol. 14, p. 264, 1894. 
This genus was based on D. grenadensis Kirby, l. c., p. 265, but 
includes a number of previously described forms, which resemble 
each other very closely. As a detailed description of one of them 
(mendax ) exists, all that seems necessary here is to tabulate and 
describe their differences. I expect that additional specimens will 
prove many of these differences to be inconstant. It may be added 
that the “ loop-nervure,” upon which Mr. Kirby laid such stress, is 
by no means a constant character. 
Analytical Table . 
Sides of thorax predominantly pale (blue or green), lips mostly 
pale.
