A FEW SPRING ODONATA, NEUROPTERA, AND

 SCOTLAND.

 some weeks in the Spey area, and was good enough, in the

Most of the insects were Dragon-flies (ODONATA). Of 

 Leucorrhinia dubia, Lind., there was a single male taken on 3rd 

 of June at Nethy Bridge. Pyrrhosoma nympJmla, Sulz., was 

 also represented by one example, a female, captured at 

 Aviemore on the 4th of June. The latter was feeding on a 

 Caddis-fly, Limnophilus centralis, Curt., and so tenacious was 

 it in its grasp that the prey was firmly held even after its 

 captor's death, presumably in the cyanide-bottle. Of four 

 examples of Enallagma cyathigerum, Charp., all from Avie-
