dingly long, three times longer tlian broad and more than twice 
as long as the distance between them. — The hairs are nearly 
cylindrical, thin, scarcely ringed; those in the first row and the inner 
pair in the second row are short, the outer pair in the second row 
about twice as long as the inner; the hairs in the third row are a 
little shorter than the outer pair in the second; in the fourth row 
the submedian pair is rather short, the intermediate pair is a little 
shorter than the sublateral hairs, which are scarcely half as long 
as the eyes. 
Antennæ (fig. 5 b). The upper one of the front hairs on the 
fourth joint is almost longer than the two distal joints together and 
more than twice as long as the other. The upper branch is very 
short, slightly more than twice as long as broad, the flagellum is 
nearly five times longer than the branch, somewhat shorter than 
the breadth of the head, rather robust and considerably thickened 
towards the end. The lower branch is even slightly longer than 
the upper, twice as long as broad, and the anterior angle is mo¬ 
derately cut off; the posterior flagellum is somewhat shorter than 
that of the upper branch and nearly two and a half times longer than 
the anterior; both flagella are shaped as the upper one, but more 
siender. The hair on the lower side of the lower branch is slightly 
shorter than the long anterior hair on the fourth joint, thin and 
not ringed. The globulus is large, shortly ovate and scarcely as 
broad as the upper branch. 
Trunk (fig. 5 c). Siender. — The fifth pair of tactile setæ is 
more than one half longer than the breadth of the segment, thin, 
with the pubescence exceedinglv faiut. The fourth pair is four 
fifths as long as the last pair and very thin. The third pair is 
three fourths as long as the fourth, from the very thin basal part 
it thickens rather feebly towards the middle and is clothed with 
rather short pubescence, while nearly the distal half is thin and 
adorned with moderately long. vertical pubescence. — The dorsal 
setæ on the last segment are very short, cylindrical. 
Anal Segment (fig. 5 d). Rather si milar to that in P. vulgaris.
