The seasonal distribution is likewise extensive. January specimens come from 
Teapa, Guatemala, Bonda, and San Isidro*; July is represented from Lumija, Colon, 
Bonda, and La Guayra. Teapa examples were taken from January to April inclusive, 
those from Bonda from July to January inclusive, those from Sapucay in March, 
September, November, and December. Some of the Surubres individuals (all taken 
in February) are noted as from “ eau stagnante,” others from ‘“‘bord de la riviére 
Surubres.” 
For the exact identification of fusca, I have relied on the specimens quoted as labelled 
by de Selys, who possessed Rambur’s type. 
In the M. C. Z. is a male labelled ‘ famula Guiana” and “ Mus. Berol.” If this be 
one of Erichson’s specimens—and it agrees with his brief description §—I regard 
this name as a synonym of fusca. The vertex is not so deeply bifid, the colour 
on the hind wings has less of the reddish tinge of typical fusca and reaches a 
little farther to the hind margin; the post-triangular rows on the front wing 
are 3, 2, 3, but a similar condition exists in otherwise typical fusca, symmetrically 
and asymmetrically. 
The Zrithemis pulla of Mr. Kirby®, I had first thought to be ochracea, Burmeister, 
but the following passage from Mr. Kirby’s reply (Sept. 24, 1904) to my inquiries 
seems to indicate fusca, Rambur, as its proper position :—“ Trithemis pulla. I think 
the species you call by this name is my 7’. erichsoni, and that the species with a red 
vertex (I don’t know why I identified it with pu//a when B[urmeister] says the vertex 
is blue) is ochracea, as you think. Of this we have a drawerful from Amazons, 
W. Indies, and Panama.... But certainly, as far as I can see, the app[endages of the 
second segment] of the sp. I called pulla are not like those figured by you as pulla, 
and much more like those of your figure of basifusca.” The last sentence quoted seems 
to me the most important. 
The “ mixed-fronted” condition is presented by a second male from Lumija (coll. 
* Intermediate in wing-colouring between @ and e.
