215, and for 1868, p. 274; also in the Proceedings of this Society, 
XV., p. 289. Having now an opportunity, thanks to the Society, for 
an actual comparison of Mr. Scudder’s types with those in my collec- 
tion, the following notes will, I hope, have an increased value, my 
previous paper being based on Mr. Scudder’s descriptions only, al- 
though these are indeed excellent. 
1. Agrion Maria Scudder. The type is a male, and identical 
with my Neoneura palustris from Cuba; Neoneura carmatica is per- 
haps only a variety of it. Mr. Scudder’s name has the priority. 
2. ? Agrion (Ischnura) coecum. The types are two males 
and one female, all having the labels in Mr. Scudder’s handwriting 
on the pins, as throughout the Odonata described by him. The 
males are Agrion coecum, and belong to the variety A. cardenium. 
The female is Agrion (Leptobasis) aduncum Hag. Syn., 79, 9. The 
doubts of Mr. Scudder of the identity with my A. coecum are thus 
explained, the female not belonging to this species. 
3. Aeschna virens. I have not seen the type. 
4. Macromia cubensis. The type is a female. This species 
is Erythemis longipes Hag. Syn., 109, 38. Later I found the Brazil- 
ian species different, and named the Cuban species to Mr. Poey 
Erythemis specularis. As I would preserve my name for the Bra- 
zilian species, after which the description was principally made, the 
Cuban species should therefore be named Er. Cubensis. 
5. Tramea insularis. I have seen one of the four male types 
and the female type described by Mr. Scudder. As I stated, Stett. 
Ent. Zeit., p. 223 and p. 226, the male belongs to Tramea imsularis, 
the female to Tr. abdominalis. As I amassured by Mr. Poey and Mr. 
Gundlach both species fly at the same time and localities, the mistake 
in joining the species is not remarkable, indeed, I even received spec- 
imens from those gentlemen wrongly paired. : 
6. Libellula auripennis. Types male and female, the species 
of Burmeister, Hag. Syn., 155, 11. 
7. Libellula angustipennis Rbr. The type is a teneral 
male, and not a female, as stated in the paper. As Mr. Scudder 
states that he took only one, and the specimen is labelled by him, 
it is doubtless the type. It is the smallest specimen I ever saw 
(length about 35 mill., the tip of the abdomen wanting; exp. al. 60 
mill.), but it does not differs from the other Cuban specimens. 
8. Libellula vinosa. Type, male and female. This is Dythe- 
mis rufinervis Burm. Hag. Syn., 162, 1.
