"White Bay. The coloration is very similar to that of the $ of eJongata. 

 It is of the same variety noticed from Port Resolution, and differs 

 from the European arctica by the two conspicuous oval yellow bands 

 on the sides of the thorax, 



^SCHFINA. 



j^schna hudsonica, n. sp., 1 c?, 4 ?, from White Bay (also 

 Canada) . 



Length of abdomen, <? , 59 mm., ? , 55 ; length of inferior wing, $ , 49 mm., 

 ?,50. 



<J . Very similar to juncea in size, coloration, the two yellow bands on the front 

 of the thorax, and the two broad bands on the sides, as well as in the three little 

 tubercles on the 10th segment, hut the pterostigma is slightly shorter and blackish. 



$ . Separated horn juncea by the shorter pterostigma (3i mm. in length ; 4^ in 

 Juncea of the same size). 



^scTina clepsydra, Say. (?), 2 $ , one indicated as from Castor 

 River. Similar to the ? of my collection (received from Dr. Asa 

 Fitch), but my ^ from Canada does not correspond with Hagen's 

 description. The ? differs from Jmdsoniea by the face having a trans- 

 verse 2^ale red line between the front and the nasus (this line is hlack 

 in hudsonica and juncea). Separated from horealis by the eyes being 

 less longly contiguous. 



GOMPHINA. 



OompJius ?, 1 ^ , from Terra Nova River, only just emerged.* 



I cannot determine the species, because the appendages are not in a 

 condition for examination. However, from the size and coloration it 

 appears to be allied to G. parvulus, Selys (of Nova Scotia). It is 

 important to note the excessively short and numerous spines of the 

 posterior femora, which arc very useful as a clue to the inferior groups 

 of the genus Gomphus. The appendages of this individual (in the 

 state they are now in) have some analogy with those of Opliiogomplms. 



Ageionika. 

 u^naUagma loreale, n. sp., 1 cJ, 1 ? , the former from "White Bay. 



Length of abdomen, ^ , 21\ mm., ? , 24 ; inferior wing, <? , 18 mm., ? , 19. 



Stature and coloration of eya^/^jjreriiOT, but differs as follows : — $ (1) The blue 

 post-ocular spots rather broader. (2) The black superior " comma " {virgule) of the 

 second lateral suture of the thorax prolonged into a line on the suture up to the 

 base of the posterior logs. (3) The sides of the 1st segment of the abdomen with a 

 fine, oblique, curved black mark, parting superiorly beyond the base and touching the 

 end of the segment posteriorly. Under-side of the 2nd segment black, this colour
