brown; abdomen whitish yellow, posterior half of each sternite and tergite dark brow 
basal half with two narrow transverse lines of same color. 
Lobes of cephalic crest widely separated, subtriangular, acutely pointed at tips. Pronot. 
breathing horns cylindrical, transversely wrinkled, tapering gradually to tips. (In the onl 
specimen at hand, the horns are widely separated at the base but soon bend proximad an@ 
thence outward and ventrad, so that the two horns are closely approximated or almo 
contiguous on their distal parts.) Behind breathing horns, mesonotum with conspicuo 
divergent lobes such as are described for E. chlorophylla; mesonotum at crest with abunda 
black setiferous tubercles, which are fewer in number, smaller, and more scattered alon 
shoulder, interrupted at mid-dorsal line. Hind legs a little longer than fore legs, whic 
in turn, are a little longer than middle legs. 
Abdominal segments with subterminal armature of posterior ring more spinous than i 
E. chlorophylia. Distribution of setae about as in EH. chlorophylla.

Erioptera septemtrionis O. 8. 
1859 Erioptera septemtrionis O.S. Proc. Acad. Nat. Sci. Phila., p. 226. 
Erioptera septemtrionis is a widely distributed species thruout th 
northeastern United States and Canada. The larvae are not uncommo 
in rich organic mud in cool, shaded woods. The writer found the 
commonly in the Standpipe Woods, Orono, Maine, in July and August 
1913. A larva placed in rearing on July 3 transformed to an adult femal 
on the 16th. Other larvae placed in rearing on July 15 transformed t 
adult males on the 25th. This limits the pupal duration to not more tha 
ten days, but it is probably much less, presumably about one week. 
Pupa.— Length of cast skin, 7 mm. 
Cephalic crest low and flat. Antennal sheaths moderately clongated, individual segment 
showing clearly thru sheaths. Pronotal breathing horns elongate, cylindrical, almost straigh 
but slightly diverging, transversely wrinkled, paler at tips, with a row of small breathin 
pores along apical margin; a few small setiferous tubercles before base of breathing horn 
Declivity of mesonotum rather steep, at crest with numerous small tubercles and abundan 
pale yellow hairs which are less numerous: along shoulder. Leg sheaths with middle pai 
conspicuously the shortest, as in the genus. 
Abdominal segments with subterminal armature of posterior ring consisting of stou 
pale setae; arrangement of these setae about as in E. chlorophylla. Lateral spiracles distine 
Male cauda (Plate LXIX, 371 and 372) with the ventral lobes blunt at tips, obliquel. 
truncated, separated by an acute V-shaped notch; dorsal lobes separated by a U-shape 
notch, each lobe terminating in a small tip, with two tiny setae on lateral face befor 
apex; dorsum of eighth segment with four prominent, pale, fleshy lobes which are closel 
approximated, the anterior pair directed laterad and a little more distant from each othe 
than the posterior pair, which are directed more dorsad. 
Neanotype.— Orono, Maine, July 25, 1913. No. 105-1913.
