Hagen, H. A. Beitrag zur Kenntniss der Tracheen -systems der Libellcn- 
Larven. Zool. Anz. iii. pp. 167-161. 
Consists of criticisms on some statements in Palmen’s “ Morphologie 
des Tracheen-systems,” with notes from direct observation . With regard 
to the statement that the stigmata are closed, he is of opinion that they 
may be open during moulting or become mechanically closed after- 
wards. The stigmata of the first abdominal segment are often over- 
looked because they lie in rather a different position to the others. 
(Notes on the tracheal system of Agrionidce are referred to under Calo- 
pterygina^ which see.) 
An abstract of Stefanelli’s paper on the preservation of the colours of 
Dragon-flies [c/. Zool. Kec. xvi. Ins. p. 213] appears in Ent. Nachr. vi. 
p. 145. 
9 additional species for Tuscany are recorded by Stefanelli in Reso- 
conti Ent. Ital. 1880, pp. 14 & 15. 
Lihelhdina. 
Great migratory swarms of Libellula A-maculata and L. depressa ob- 
served in various localities in Galizia in May, 1880; J. Schaitter, SB. z.-b. 
Wien, XXX. p. 40 ; cf. also Ent. Nachr. vi. pp. 133 & 167. An anonymous 
note in Feuill. Nat. x. p. 15, on a great swarm of Lihellulidce observed at 
Havre on Oct. 7th, perhaps refers to some species of Sympetrum. B. 
Torrey, Am. Nat. xiv. p. 132, records an enormous swarm of Dragon-flies 
(species not given) at Weymouth, Mass., on June 2nd ; the column was 
at least a quarter of a mile in width, and the migration lasted all day ; 
on the 23rd of the same month a similar swarm was observed near Boston; 
in both cases the course was westward. At p. 594, the same writer records 
another swarm observed on May 24th in the next year.
