stones of the bottom, a few larvae of this species. They were not 
reared, but the abundance of adults issuing in the tent, and the 
great likeness of the larva to that of the closely allied genus 
Dicranota, as described and figured by Miall,* leave scarcely a pos- 
sible doubt as to its identity. 
The larva [fig. 19e¢] measures in length 8-9 mm, with the caudal 
processes I mm additional. Diameter 1 mm. The body is cylin- 
dric and tapers forward on the thoracic segments, which while 
aecreasing in diameter increase in length, the first segment, 
within which the head is wholly retracted, being twice the length 
of the third. At the base of the first segment is a narrow 
interpolated ring, which, in Dicranota Miall interpreted as 
a posterior division of the basal abdominal segment. So _ in- 
terpreted, the abdomen consists of 9 segments of which the 
first two and the last one are legless, while the intervening 
five segments bear’ prolegs. These prolegs are fleshy, retrac- 
tile, unpaired and widely separated on the mid ventral line, 
and each bears a circlet of outcurved hooklets at its tip, and 
diminishing series of lesser hooklets, graduating into the 
scurfy pubescence of the general integument, back from the tip. 
The skin is of a dirty whitish or yellowish white color, and 
its appressed pubescence is roached up into two tranverse lines 
on each of the leg-bearing segments (which thus, and by reason 
of a slight constriction between these ridges of pubescence, 
is made to appear double) and into single lines on the other 
segments. The abdomen tapers abruptly upon the eighth seg- 
ment to the end and bears at its tip two long, fleshy filaments 
that are obtusely pointed and bear a few short, terminal hairs. 
Above the bases of these filaments is the imperfectly developed 
respiratory disk. The two bare spiracles are surrounded by 
roundly curved, raised lines of pubescence, and separated by 
a median groove, upon which, as a hinge line, apparently they 
may be folded up together. I take it that these spiracles are 
exposed in air, and closed together in water, and that four anal 
tracheal gills that may be seen projecting by their tips from 
the anus, are then protruded for aquatic respiration. ‘This is 
a common arrangement for amphibious life in crane fly larvae. 
However, I merely collected these, and did not study their 
habits.
