NOTES ON LIFE-HISTORIES, LARVH, ETO. 133 
rather light. Hairs long, tapering, and thorny—some dark, others 
light. Tubereles, dorsal abdominal tubercles are single-haired, i inner, 
bears a small pale hair, ii outer, bearing a larger dark hair ; iii, supra- 
spiracular, is a cone-shaped tubercle bearing three or four hairs. The 
subspiraculars are difficult to determine in so small and hairy a larva, 
but I think they are consolidated [Unfortunately I was unable to 
complete the above fragmentary notes of the first larval stage or to 
take any notes on the later ones, owing to the large amount of attention 
required by some other species.]}. Hasirs or Larva.—It is worth 
mentioning, however, that the larva is possessed of considerable powers 
of jumping when startled or touched. With a sudden jerk it flings 
itself into the air covering a distance many times its own length. 
This habit is present during several instars. In the second it is even 
more noticeable than in the first; the distance covered being some 
two inches or more. But as the larve grow larger they become less 
active, and require more stimulus to start them, the jump being 
proportionally lessened. In jumping the larve seem to be able to 
turn round or over while in mid-air, as they always alight with their 
heads facing the cause of the stimulus (with my larve usually a 
small camel hair brush or pencil). I was not, however, able to detect 
the action which enabled them to jump owing to the rapidity of their 
movements. This habit is probably of great use to them in evading 
the attacks of birds, hymenopterous or dipterous parasites, spiders, &e. 
The larva hybernates when about 4’ long, its habit being somewhat 
similar to that of Notolophus gonostigma, spinning a silk web or pad on 
a leaf as if about to moult.—A. Bacor, 154, Lower Clapton Road,

THE LARVA OF OIKETICUS oMNIVoRUS, FEREDAY.—S1zE: 23mm. long, 
6:25mm. in thickness, at middle, tapering to each extremity. Conour: 
Head, and thoracic segments spotted and streaked with brown on a 
cream-yellow ground colour. The abdominal segments are dull brown, 
except at the sides where the mid-lateral swellings on each seement 
form an irregular cream coloured line. Srructure (under one-inch 
objective).—Dorsal and Lateral views : Head—The six ocelli are 
arranged in ‘‘ crescent’ at the lower anterior area of lobe; below the 
crescent are two hairs, within it are three hairs, and above it are two 
hairs, besides which there are hairs along the frontal portion of lobes 
and on clypeus; antenne have a broad, white, fleshy base, a narrow 
white second joint, a longer brownish (chitinous) third joint, and from 
the latter project two terminal processes, a long bristle, and a small 
joint which likewise gives out one terminal process, and a two-jointed 
process. The outer maxillary palpus is terminated by a blunt joint, 
and there are four inner processes. The labial palpi are in front, and 
rather more than half the bulk, of the spinneret, which is not nearly 
so slender nor so long as in the Hepialidae for instance. Prothorax: 
The whole dorsal and lateral area consists of a smooth hard shield, no 
definite scutellum is distinguishable, on the dorso-lateral area are 
two single-haired tubercles, representative of the trapezoidals, but 
reversed in position, 7.¢., the anterior are remote from, the posterior 
close, to the median line; on the anterior lateral edge of segment is a 
marginal series of four hairs, with two others inner to these at the 
lower end of series, thus there are three hairs below the spiracular 
position, and anterior to it. The spiracle isa raised mahogany coloured
