5 GEORGE v., A. 1915 



It is the latest of the four species of Gomphus to appear in the adult state, 

 the first tenerals emerging a few days later than those of G. lividus and remaining 

 for some time after the other species of Gomphus have disappeared. In 1907 the 

 first adults on the Station Island emerged on June 22, continuing to appear until 

 about the 30th, while in 1912 they were first observed on the 19th. In 1907 and 

 1908 they were exceedingly abundant, apparently outnumbering both lividus 

 and spicatus] in 1912, however, they were scarcer, their numbers being distinctly 

 smaller than those of either of these species. In 1907 a few individuals lingered 

 as' late as Aug. 12. 



Though usually transforming early in the morning, this process may some- 

 times be observed at other times of the day. 



Like its associate, G. lividus, this species often falls a victim to Hagenius 

 brevistylus. 



26. Gomphus spicatus Hagen. 



This is distinctly the earliest Gomphine and one of the earliest dragonflies to 

 appear in the adult state in the spring. When we arrived at the Station in 1907, 

 on June 15, tenerals were already common in the neighbourhood of the small 

 lake near the outer coast, and in 1912 they were much earlier, an exuvia having 

 been taken on May 29th, and a very large number on the 31st. These were found 

 floating among the reeds in the marshy outer end of Galbraith Lake. On June 

 15 of same year, large numbers of tenerals were flying about the same marsh and 

 many more mature individuals in the open rocky woods nearby. On June 5 

 great numbers of spicatus were seen about one of the shallower lagoons on the 

 Giant's Tomb Island, all apparently beyond the teneral state. By the 15th its 

 numbers had about reached their climax in the vicinity of Go Home Bay. They 

 did not wholly disappear untU somewhat after the middle of July. The last pair in 

 copula was noted at the Giant's Tomb Island on July 15. 



G. spicatus is strictly an inhabitant of marshy places in this locality, though 

 Kellicott ('99) states that it frequents the "borders of wave-beaten shores or rush- 

 ing rivers," and Needham refers to it as an inhabitant of "all sorts of waters." 

 These statements, especially the former, are difficult to associate with this Gomphus 

 and it seems to me probable that Kellicott's may refer to some other species. 

 The nymph is a very common object in dredging from the soft bottoms, consisting 

 chiefly of rotten vegetation, of ponds and still marshy bays. 



Transformation takes place close to the waterline, the nymph frequently 

 not emerging completely. The exuviae are thus often found floating. 



27. Gomphus fratemus (Say) Selys. 



This species does not occur in the immediate vicinity of Go Home Bay, but 

 it is included here on account of the capture of a male specimen by Dr. A. G. 

 Huntsman, near Victoria Harbour (Hog Bay), June 25th, 1907.
