Pronotal bresihing horns directed cephalad and dorsad; mesonotum bearing two pairs of 
spines, the more anterior being the smaller, situated just behind breathing horns, posterior 
pair the larger; metanotum with two pairs of spines; abdomen with first tergite bearing 
two pairs of spines, the first having two lateral branches, the second simple; second tergite 
bearing two pairs of spines, the first with two lateral branches, the second with one branch; 
third tergite bearing three pairs of spines, the first very short and simple, the second with 
two lateral branches, the third with one branch; tergites 4 and 5 with three pairs of branches, 
the first two similar to those of third segment, the last possessing two lateral

ronotal breathing horns directed cephalad and ventrad; mesonotum spineless; metanotum 
with one pair of spines; abdominal tergites bearing but a single pair of appendages, which 
are unbranched and correspond in position to the last or more posterior of those of the

Liogma nodicornis, the only American species of the genus, is widely 
istributed thruout the Northeastern States. The larvae are found in 
oss — Hypnum cupressiforme Linn. and related species. They are the 
ost sluggish of any crane-flies known to the writer, moving only with 
reat slowness and much of the time appearing to be quite dead. They 
rawl about among the stems of their host plant and probably never leave 
t, even to pupate. The pupal duration indoors is not more than six 
ays. Further details of the life history are given by the writer in an 
arlier paper (Alexander, 1914). 
Larva.— Length, 14.5-15 mm. 
Width, 3 mm. 
Depth, 2.5 mm. 
Color of live larva light green, the numerous spines covering the body darker; sides with 
even black marks, the first on first abdominal segment, the last on seventh abdominal 
egment; the marks on ends the smallest and least distinct, the five intermediate marks 
arge and conspicuous; these marks all lying parallel to one another; posterior face of ventral 
obes surrounding stigmal field intensely black. 
Prothorax in front (Plate LX X XV, 462) sloping from anterior end, on ventral slope provided 
ith liplike lobes, with a transverse slit from which head capsule is exserted; upper lip the 
igher, not strongly chit:nized, provided with a few small, scattered bristles, these more 
umerous on sides of lobe; lower lip not so high, with small, scattered bristles not arranged 
narow as in L. glabrata; at angle of slit a small rounded lobe bearing a small bristle. Dorsal 
ody appendages reduced to a pair of lobes in front, separated by a space a little greater 
han diameter of one, and a pair of smaller lobes behind, very widely separated; lateral body 
ppendages long, conspicuous; ventral body appendages not apparent. Meso- and meta- 
horax swollen and arched ventrally like prothorax; dorsal appendages two, a small conical
