A CONTRIBUTION TO THE ODONATA OF MAINE.— II. 



Specimens taken near Orono, Penobscot County, Me., 1891. 



By F. L. Harvey, Orono, Me. 



(Continued from Vol. II, Nos. 3 and 4, 1891.) 



Tribe I.— AGRIONINA. 

 Subfamily i. — Calopterygina. 



1. Calopteryx maculata Beauvois. — Though very abundant 

 last year, was very scarce this season. Specimens were taken, 

 June 13th, in swamps in deep woods, but we visited the locality 

 about the same date where they were abundant last season, but 

 took none. Can it be that this species requires more than one 

 season to transform? 



2. C. cequabilis Say. — This species seems to be scarce; took a 

 single specimen June 13th. 



Subfamily 2. — Agrionina. 



4. Argia putrida Hagen. — Specimens taken June 20th, over 

 roads. 



6. Ischnura verticalis Say. — Taken June 13th, but no orange 

 forms observed until July 22d, when they were common, but were 

 not observed mating. 



8. Enallagma Hageni Walsh. — Taken June 13th and 20th, 

 and July 22d. 



39. Enallagma signatum Hag. — ^July 23, 1891, Chemo Stream 

 near the lake; quite abundant. As many as fifty seen in patches 

 of Juncus and over lily pods. We were botanizing with some 

 friends, and had time to take only five specimens. We went to 

 the locality July 28th, and not a single specimen could be found. 

 There had been a heavy rain between the dates. Hagen gives 

 the habitat of this species as Georgia and Louisiana.* Mr. Cal- 

 vert writes that it occurs about Philadelphia, Pa. To find it abun- 

 dant so far North is certainly interesting. 



40. E7iallagma pollutum Hag. — ^July 23, 1891, Chemo Stream 

 with the above, but not so abundant. Several seen, however, 

 but only three taken. On July 28th a single specimen was seen 

 and taken. This species is recorded only from Florida (Hagen, 

 1 86 1, p. 84) so far as we know. To find this southern species so 

 far North, and no intermediate localities, is, indeed, remarkable.
