PSYCHE. 



[August lSq7- 



nine per second and the duration as 

 before, but the observation was not a 

 very extended one. Later, at tlie same 

 place I took more careful observation, 

 and have noted it as certainly correct, 

 that the duration was as before and the 

 rate ninety-four in fifteen seconds. As 

 in Chloealtis conspersa the first one or 

 two strokes are frequently noiseless, the 

 femora apparently failing to strike the 

 tegmina ; and when they are struck the 

 notes are shorter than the succeeding. 

 At Sudbury, Vt., this species occurred 

 almost exclusively in the uplands, rarely 

 in the low meadows. 



The ovaries are very large and thick, 

 pale pinkish at base, pale or colorless 

 apically ; the eggs appear to be ar- 

 ranged upon them like the bristles of a 

 brush, having their free tips turned 

 toward the middle line of the body ; the 

 larger eggs are beneath and the upper 

 portions of the ovaries are attached 

 together quite strongly by a delicate 

 tissue. The eggs of opposite sides 

 touch by their tips, are pale yellowish 

 and appear to be in three, possibly foiu', 

 tiers. Of several females dissected 

 August 15,1 counted in one 39 eggs on 

 one side, 30 on the other ; in another 

 45 and 42 respectively ; in a third, 38 

 on each side. Still another had no eggs 

 at all, but instead the entire abdominal 

 cavity was crowded with the coils of a 

 Filarian worm, which when removed 

 measured nearly two feet in length. 



Encoptolophus sordidus (Burm.). 

 The imago first appeared at Sudbury, 

 Vt., on Aug. 15, in 1S6S, the specimens 

 still pale from freshness. In Cam- 



bridge, Mass., Oct. 10, iS67,the males 

 were very abundant, but not a single 

 female was noticed. 



The eggs are extruded cap-end fore- 

 most, and laid in a mass in drilled holes 

 in bare spots in sandy compact loam, 

 so deep that the top of the pod is about 

 two centimeters below the level of the 

 ground. Late in the afternoon of Sep- 

 tember 30, at Andover, Mass., I noticed 

 a female which had just completed her 

 task standing within her own length of 

 her fiUed-up hole, the whereabouts of 

 which was revealed by the scratched 

 appearance of the soil, completely ex- 

 hausted ; her ovipositor was hoary with 

 froth and she made no attempt to 

 escape. She had evidently further eggs 

 to lay. A second open hole only a 

 few centimeters away had no eggs, but 

 near the bottom an elaterid larva was 

 discovered which probably led to the 

 abandonment of the hole. 



Camnula pellucida Scudd. July 

 32, 1S67, this species appeared in very 

 great numbers at Jefferson, N. H., the 

 males more abundant than the females. 

 It was the first pleasant day after four 

 days of storm, just before which the 

 fields where these occurred showed no 

 mature specimens at all. 



Dissosteira Carolina (Linn.). The 

 eggs are laid in a mass as in Melano- 

 plus, only the pod is larger. In one 

 found in Springfield, Mass., laid in 

 damp soil, there were about forty eggs, 

 which were laid not horizontally but 

 with a slight obliquity, and the diameter 

 of the pod was about half as long again 

 as one of the eggs. In a pod formed
