388 THE CANADIAN ENTOMOLOGIST. 



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 

 diied. 



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 Tceniorhynchus scales, and 

 having violaceous reflections. Fork cells very long; ist submarginal 

 about a fifth longer and somewhat narrower than the 2nd posterior cell, 

 stem not half the length of the cell, and the same length as that of the 2nd 

 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. 



Length 5.5 mm. Taken Aug. 3, 1905. Habitat, Rock Island 

 Arsenal, 111. 



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 

 Fi?ilaya, 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 Fiiilaya. 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. 



Another instance of small variation occurs in the Culex cotifirmatus, 

 Arribalzaga, sent me by Lieut. R. Boyd Miller, Asst. Surg. U. S. A., from 

 Fort Screven, Tybee Island, Ga., which agrees perfectly with the descrip- 

 tion given by Theobald (Monograph, Vol. II, pg. 42), except that the 

 femora are white nearly to the apex dorsally as well as ventrally, and all 

 the ungues are uniserrate; the latter is, of course, the important variation. 



(To be continued.)
