small light brown spot, which, under low magnification, shows 

 many small perforations. The long curved egg is placed ver- 

 tically in the plant tissue. The larva on hatching must find its 

 way over the leaf surface to the water. 



The apical black ring and the sub-apical dorsal black spot on 

 the second abdominal segment of the male were separate in 20 

 males of cah'crti and 8 males of cvalliigcniin, very narrowly 

 joined by a dorsal line in 13 males of caherti and 2 males of 

 cyathigerum, more broadly joined in 9 males of calrcrti and 1 

 male of cyathigerum, and very broadly joined in 3 males of 

 calrcrti. 



"When we visited the swamp on June 6, Lestcs ford pat us 

 was very numerous as tenerals in the low adjacent woodland 

 and as adults, singly and with many pairs in couple, over the 

 marsh. On June 13 Lestcs u neat its was the more abundant 

 species, many pairs being seen. On both dates numbers of 

 Iscliunra verticals were seen, Ana.v jitnius was ranging freely 

 over the entire swamp, and on June 6 an occasional male of 

 Epiaeschna hcros passed high overhead from the forest and 

 back again into the forest, while a few females prowled the 

 ill-defined shore line, occasionally alighting to oviposit. ( )n 

 June 13 a single freshly emerged hut mature male Aeshna

 the swamp, near the outlet, and succeeded in netting two of 

 them. On the same date Pachydiplax lonyipennis and Er\- 

 Ihcinis simplicicollis were generally common, the males of the 

 la'ter species frequently displaying their unique performance 

 by two individuals of flying about each other in intersec in-

In 1 ( X)7, when the Enallagmas were discovered at the Yane-
