fy, 
wide, cushion-like, elevated, and with several rows of bristles, which, 
however, ascend only to the tip of the third antennal joint. The gene 
are densely covered with erect hairs; on the lower margin of the same 
are longer sete. The bristles of the head are more dense in the female 
than in the male, but in the latter the bristles are somewhat longer. 
The seutellum has, besides the marginal bristles, on the disk two very 
pronounced macrochete amidst the shorter pubescence. The abdomen 
shows along the entire hind margin of the third segment *one row of 
macrochete; the fourth segment is, on its upper surface, beset with 
long hairs and bristles, the latter being denser in the male than in the 
female. Aside from these there are no macrochete. The wings have 
no distinct marginal thorn; the posterior transverse vein is nearer to 
the curvature of the fourth longitudinal vein, which has no appen- 
dicular branch, than to the small transverse vein. The posterior tibie 
are furnished on the upper side with a row of equally long, very stout 
and dense sete, which sometimes are closely applied to each other so 
that the tibia has the appearance of being unistriately ciliate. The 
pulvilli and the claws are longer in the than in the 2; the front 
tarsi of the latter are hardly flattened. 
I must remark here that in his Hist. Naturelle des Dip. des Environs 
de Paris (1863, 1, p. 893), Robineau Desvoidy has established a genus, 
Verreauxia, on a Tachinid from Tasmania, which appears to be very 
closely allied to Crossocosmia m. It agrees with the latter in the ar- 
rangement of the bristles of the abdomen as well as in the shortness of 
the two basal joints of the arista, but the frontal pubescence is quite 
different, and is described as follows: “ Front n’ayant que de cils raids, 
petits et peu prononcés.” 
Regarding the specific determination as given by Sasaki, in his above 
cited paper, the following points could be added: The fly resembles in 
general appearance Nemorwa pellucida, Meig.* The antenne are shorter 
in the male than in the female; the first and second joints, as well as 
the blackish pubescent palpi, the suctorial flaps of the proboscis, and 
the distinctly separated oval margin are rust colored; the arista is long, 
moderately thick at basal half, thence gradually narrowing. The frontal 
Stripe is velvety black, the frontal orbits are black inferiorly, with 
whitish pruinescence, which extends more densely over the whole face 
and over the gene, and which has a more yellowish tinge in the ¢. 
The bluish-black thorax is-sparsely grayish-white pruinose, especially 
in front, and has four narrow, equidistant, black longitudinal stripes, 
of which the two inner ones do not extend much beyond the transverse 
suture, and show between them, anteriorly, a trace of a median stripe.t 
The seutellum is rust-brown with a slight whitish tinge; the bluish- 
“There is no need of changing this to Nemorwa conjuncta Rond. 
tThe four rows of dorso-central bristles consist in front of the transverse suture, of 
three bristles in each row, behind the transverse suture the two inner rows have 
three bristles each, the outer ones each four.
