It is thus evident that this is not the larva of any of our larger 
species of Tipula, and another correspondingly large form has to be considered. 
I am, therefore, inclined to look upon this as probably the larva of Longun'o 
testaccus Lociv. This species is not at all common. I have only seen one from 
Fairmount Park, Philadelphia, collected by Mr. H. 1 ). Coyle, and two taken by the 
writer at the Delaware Water Gap, July 12, 15, 1898, along Dunnfield Creek, a 
cool mountain stream flowing into the Delaware on the New Jersey side. It is to 
be hoped that this description and figure will lead to the positive identification of 
this interesting larva. 
Limnobia Triocellata Osten Sacken. Plate I, Figs. 3, 4. 
The larva of this species was found in considerable numbers in fungus in 
the woods at Riverside, near .\uburndale. Mass., .August 21, 1904. They com- 
menced pupating the following day, and the imagos appeared on the 30 and 31. 
riie larva (Fig. 3), is about 18 mm. in length, cylindrical and gradually 
tapering towards the ends ; color, a translucent yellowish white ; mouth parts 
dark brown. The finely roughened transverse lines at the margins of the seg- 
ments aid in its locomotion. The larva when found is apparently enveloped in a 
mucus-like covering, and when disturbed moves very rapidly through the fungus 
in either direction. 
The pupa (Fig. 4) is about 13 mm. in length; yellowish at first, the wings 
and legs becoming a dark brown with age ; antennae curve above the eyes, and 
disappear beneath the wings ; the legs lie parallel to each other on the ventral 
surface, the tarsal claws ending near the middle of the fourth segment of the 
abdomen. 
.Vrchvtas hystri.x Fabr. 
Phis sjrecies was bred from Datan,i major Grote, July 7, 1905. by Mr. .A. C. 
Sampson of Sharon, Mass. I can find no previous record of its host.

While searching beneath the bark of pine logs for the larva of Xy!ophas;us. 
1 found the larva of this species in considerable numbers. It frequented the 
wet bark near the ground where there was more or less fermentation of the sappy 
portions of the wood and bast. The larva (Fig. 5) is about 14 mm. in length, 
of a dirty yellow or brownish color, with ten or eleven ill defined, rugosely 
wrinkled segments, covered with short hairs, which are somewhat longer on 
the sides. 'Phe first segment is armed on each siile with a pair of black spines.
