along the River Grand-Anse. It once alighted on the limb of a tree 

 within full sight, but beyond the reach of my net, and it ajjpeared to 

 me to be this species. 



LICELLULINA. 



No species of Epitheca or CorduUa were seen by me, although I 

 maintained a sharp lookout for them. 



Tramea insularis Hagen. Tiie species jorocm-ed by me agrees 

 perfectly well with the description of Dr. Hagen, while it disagrees 

 with that of T. abdominalis Hagen, in the length of the superior 

 anal appendages. It also corresponds with specimens collected 

 by INIr. Scudder in the Isle of Pines, and which were presented to me 

 tlu'ough his generosity. Both sexes were taken together in one 

 place. This species seemed to be rather common, hovering over the 

 dusty road and flying usually at a height of ten to fifteen feet above 

 the ground. Its flight is rapid, but not so clashing as that of T, lac- 

 a'ata Hagen. They are difficult to capture, because shy and wary. 

 Two males were obtained, which agreed perfectly with the others, 

 except in the color of the front and vertex, which were not blue, but red- 

 dish. Unfortunately these two specimens shared the fate of several 

 others in being destroyed by the minute ants which there overruii 

 • everything. At no time did I see this sjjecies affecting the bushes. 

 They were ever on the wing, flying backward and forward through b 

 limited sjiace over the roadside. 



It was observed in March, April and May. No specimens were 

 seen in the mountains, but in the valley close by the Grand-Anse 

 River they apjDcared to be most numerous. 



A female in my collection, from St. Thomas, occupies an interme- 

 diate position between T. abdominalis and T. insularis. It agrees 

 with the former in having no blue upon the front and vertex, the anal 

 superior apjiendages are a little more than the length of the two last 

 segments, and the spots of the wings and remaining characters are 

 those of 2\ insidaris. May not the two so-characterized species be 

 nothing more than local forms of one ? 



In Tramea lacerata Hagen, the front and vertex are usually steel- 

 blue, but I have seen sjjecimens agreeing in other respects, yet differ- 

 ing in having these parts reddish, or with only a vestige of blue upon 

 the front. When recently excluded, the blue of this species is very 

 faintly discernible. I cannot help supposing the species of Mr. 

 Scudder to be the T. insularis Hagen. It agrees so perfectly with 

 the description of Dr. Hagen, while it equally disagrees with that of 

 his T. abdominalis. There is but little unitbrmity in the number of
