to six a conspicuous rounded brown spot on the sides of the segment 
near the base; sternites one to five yellow more or less suffused with 
brown, the terminal sclerites yellowish. Male hypopygium with 
the ninth tergite (see Plate XIX, fig. 50) rather prominent, flattened, 
the caudal margin with a broad and deep U-shaped notch and trifid, 
consisting of the flattened subacute lateral lobes and an acute median 
point; an indistinct median dorsal furrow. Ninth pleurite promi- 
nent, complete, rounded oval. The outer pleural appendage (see 
Plate XX, fig. 65) is situated near the end of the sclerite, strongly 
arcuated in the form of a boomerang, pale, covered with setigerous 
papillae, the apex ending in a conical pale horny point. The inner 
pleural appendage (see Plate XX, fig. 66) is more chitinized, the 
apex heavily chitinized and blackened, deeply split into two lobes; 
around the notch on the inner face of the appendage is a group of 
about twelve prominent setigerous tubercles; a group of about four 
similar tubercles down the inner side of the appendage; outer face 
of this organ wdth several prominent subparallel ribs. The penis- 
guard viewed from the side (see Plate XXI, fig. 79) deeply bilobed 
by an oval-rounded notch; the ventral margin is produced into the 
gonapophyses which are much longer than the penis-guard which 
they subtend (see Plate XXI, fig. 78) ; these latter are flattened and 
blade-like, the apex produced into a point. Ninth sternite scarcely 
if at all notched medially beneath, the caudo-lateral angle beneath 
the pleurite with a broadly rounded lobe which is densely covered 
with tubercles bearing long yellowish hair, these tending to be con- 
torted at their apices. Eighth sternite not projecting, the caudal 
margin straight or nearly so, bearing a tuft of long yellow hairs on 
either side, including two long, powerful, chitinized, decussate bristles.

where they form part of the Loew collection.

hypopygium with the ninth tergite small, the caudal margin with a 
V-shaped notch ; the pleurite is produced caudad into a slight 
flattened expansion.
