In Dakota, the females of a species of Lestes descended the stems of 
water-plants for oviposition, and remained beneath the surface to a depth 
of several feet for fully half an hour. On reappearing, the female was 
seized by the male and towed ashore. The copulatory act is detailed for 
Lestes. A species of JEschna was seen to dash against the water, 
apparently for a bath, or for freeing itself from parasites. 
In Sumatra, the butterfly Leptocircus virescens mimics dragon-flies 
in company with which it is found ; H. 0. Forbes, A Naturalist’s Wander¬

Supplementary to Cabot’s Monograph \cf. Zool. Rec. ix, p. 393], 
with much additional information. At pp. 286 & 287 the author deals 
with the question of the separation of the two groups, which he main¬ 
tains are of equal value, the nymphs of the Cordulegastrina being espe¬ 
cially remarkable for the form of the mask, and for the tarsi of all being 
tri-articulate. Short prefatory generalities are given. The species noticed 
are Onychogomphus lineatus, Selys, and one doubtfully of the genus from 
the Himalayas ; Herpetogomphus menetrisii, Selys (?), and compositus,
