those on the lateral lobes a very dark brown, long light bristles, 
probably six, on the mid lobe ; pleura very dark, with a few 
large patches of white flat scales; metanotum dark brown, 
Abdomen dark, heavily scaled with dark brown flat scales 
(with violaceous reflections), and small white, basal, lateral spots, 
apical hairs light; venter mostly white scaled, but dark apical 
bands on some of the distal segments. There is some suggestion 
of tufts on the ventral side, but not well marked, and may be due 
to the position in which the specimen dried. 
Legs, coxae and trochanters light and sparsely light scaled ; 
ventrally the femora are all light scaled, and in the hind legs are 
dorsally light scaled, about one-half (basal) their length, and are 
rather heavily bristled. The remainder of the legs is brown, 
with the exception of a rather brilliant knee spot on the hind 
legs, a smaller one on the mid legs, and in some lights a light line 
the length of the fore tibiae on the caudal side; ungues rather 
large and heavy, equal and uniserrate. 
Wings clear, brown veined, rather heavily scaled with dark, 
broad truncated brown scales, suggesting typical Taeniorhynchus 
scales, and having violaceous reflections. Fork cells very long; 
first sub-marginal about a fifth longer and somewhat narrower 
than the second posterior cell, stem not half the length of the 
cell, and the same length as that of the second posterior ; the 
supernumerary cross-vein a little interior of the mid, and about 
the same length, the posterior nearly twice as long as the mid 
cross-vein, and more than double its own length interior; 
halteres light. The third vein extension is more marked than 
often found, but not so decided as in Desvoidea fusca , Theob.

Described from one specimen sent by Dr. G. G. Craig, Cont. 
Surg. U.S.A., in some very interesting collections from Rock 
Island Arsenal. While the characteristics do not agree fully 
with Theobald’s definition of Finlaya , they correspond more 
closely to those of this than to those of any other existing genus, 
and I have therefore referred it, provisionally at least, to 
Finlaya. The species is extremely interesting, because it is, so 
far as I can ascertain, the first having this peculiar grouping of 
scales to be reported from the United States ” (Ludlow).
