abdomen are many more similar rows. The ventrum of abdomen is 
also provided with such rows, and the ventrum of the cephalothorax 
including coxæ is covered with these spines. Palpi large and longer 
than the body ; thickly covered with long black spines ; femur enlarging 
a little from base to apex ; patella thick, subcylindrical, with a conical 
tubercle on ventral surface near distal end; tibia slightly petiolated, 
curved and attenuated distally, hollowed out on under side to receive 
tarsus; tarsus petiolated, swollen, a little more than half as long as 
tibia, rounded at end and having no claw; capable of being turned 
_back upon the tibia like a thumb. Mandibles short, much shorter 
than body ; first joint having a large, truncate, wart-like tubercle on 
dorsal surface near distal end; top of tubercle and dorsal surface of 
distal portion of the joint thickly furnished with stiff spinose hairs; 
second joint short and thick, provided dorsally with similar hairs; 
claws curved, unequal. Legs rather slender, with rows of spinose 
hairs on proximal joints, Shaft of genital organ long, flattened; 
toward tip enlarging into a spoon-shaped portion, from which there 
projects forward a long slender piece gradually coming to very acute 
point. 
Described from one specimen taken at Hanover, New Hampshire.

The Puparium of Jurinia.—In a paper recently sent to the 
American NATURALIST, I described the puparium of Blepharipeza. 
The present paper describes the puparium of Jurinia, which genus, 
while it belongs to the same group as Blepharipeza (Hystriciine), 
shows considerable difference in the puparium. The description is 
drawn from a puparium of Jurinia algens Wd., from which issued a 2 
specimen of the fly, bred by Professor C. P. Gillette from Hadena 
lignicolor, in Colorado. 
Puparium of Jurinia algens Wd.—Length, 12 mm.; greatest width 
(8th segment), 54 mm. Color reddish brown, capital tubercles and 
anal stigmata blackish. Puparium consisting of 12 segments, including 
capital and anal plates, more or less cylindrical, bulging a little pos- 
teriorly, the anterior end being less in diameter than the posterior en@, 
while the eighth segment is the widest portion. The rugose belts 
described in Blepharipeza are absent, the whole surface being more OF — 
less fluted, the flutings showing most plainly on the three anterior 568- 
ments next the capital plate, becoming less distinct in the middle oF — 
giving way to an almost smooth surface, and reappearing in irregular e 
flutings, or minute furrows and ridges, on the last three segments and a
