244 ENTOMOLOGICAL NEWS. [October, 



During- the past Summer (1894) I noted the following species 

 at Wood's Holl, but the observations have not the slightest pre- 

 tension to being exhaustive: 



* Enallagma durum Hag. July 9, 19. 



civile Hag. July 5, 9, 19 (ovipositing), Aug. 8. 

 aspersum Hag. July 9. 

 Ischnura verticalis Say. July 5-Aug. 8. 

 'Anax junius Dru. Aug. 8. 



auripennis Burm. July 19 (ovipositing), Aug. 8. 

 semifasciata Burm. July 9. 

 piilchella Dru. July 9, 19, Aug. 8. 

 Plathemis trimaculata Dru. July 9, 19, Aug. 8. 

 , "Micrathyria berenice Dru. July 5, 9, 19 (ovipositing, $ clasping 9 )> 



Aug. 8 (do.). 



Celithemis elisa Hag. July 19 (ovipositing, $ clasping 9)- 

 Diplax rubicundula Say. July 9, 29, Aug. 8. 

 /Mesothemis simplicicollis Say. July 19. 



The Elizabeth Islands are a small chain stretching in a south- 

 westerly direction from the mainland at Wood's Holl. The 

 chief members of the group, from the mainland southwestwards, 

 are Nonemeset, Uncatena, Naushon, Pasque, Nashawena and 

 Cuttyhunk. On August 10, 1894, I took the following species 

 at fresh water ponds on Nonemeset: 

 Enallagma civile Hag. ^/E. donbledayi Selys. E. aspersum Hag. 



And on July 17, 1894, at fresh water ponds on Cuttyhunk, I 

 found: 



Lestes unguiculaia Hag. Trained sp. (Carolina L. ?) 



" forcipata Ramb. *^Libellula auripennis Burm. 

 * Enallagma durum Hag. piilchella Dru. 



civile Hag. Diplax rubicundula Say. 



^Jschnura verticalis Say. Mesothemis simplicicollis Say. 

 Anax junius Dru. 



Of these records, the most interesting is undoubtedly that of 

 Enallagma doubledayifaom Nonemeset, as this species has hitherto 

 been .known from Florida only. The six males which I secured 

 agree completely with Floridan specimens. 



It was not my good fortune to find Anax longipes Hag. which 

 Dr. Hagen took at Wood's Holl Aug. 26 and 27, 1875 (see 

 " Ent. Mo. Mag." xx, p. 169, 1884), although I was on the 

 lookout for it.
