closely packed as to resemble a growth of aquatic vegetation. The black 

 flies were very abundant in the woods." 



The pouch or case is similar to that described by me for S. pictipes. 

 The nymphae and larvae seem to be the same, but that the pupa has on 

 each side nine lilaments instead of eight, as stated for 6". pictipes. I 

 made a new examination of my material and found this number variable, 

 without possibility to ascertain that one filament is broken off. I see 

 nymphae with eight or with nine filaments on both sides, and have 

 ascertained in one specimen nine on one side and eight on the other. I 

 think more material is needed to decide if one filament in such cases is 

 perhaps wanting as a consequence of a previous mutilation. The flies 

 sent by Mr. Hubbard, without certainty to belong to the pupae, are only 

 half the size of S. pictipes, and differ in the color of the legs. But the 

 few specimens of S. pictipes which I have seen are newly hatched and in 

 alcohol. Tlie flies sent by Mr. Hubbard are considerably smaller than 

 those described by Mr. Barnard, and differ also by the color of the legs.

To prevent later uncertainty about the types of Simuliuvi in the col- 

 lections of the Museum, I have to state that the collection of O. Sacken 

 contains named only S. vittatuni^ and the collection of Loew only S. 

 vmustiim and S. quadrivittatum. . S. inveniistum and piscioidiiun, though 

 starred in the catalogue of O. S., have not been found in his collection. 

 There is without name only one specimen from Hudson's B. Terr, (none 

 in Loew's), and no specimens from Mumford, N. Y. Only two later col- 

 lected from Goat Isl., and one labeled by myself from Trenton Falls. 

 Loew's collection has no species from N. Y. In both collections are a 

 number of unnamed specimens, and Mr. Hubbard's species seems to 

 agree with one from the Saskatchewan River. 



LIST OF NORTH AMERICAN BOMBYCLE OF HUBNER. 



BY A. R. CROIE. 



Since I first catalogued our species of Bombycice., under Herrich- 

 Schseffer's later designation of Cymatophorince, in the Proc. of the Ento- 

 mological Society of Philadelphia for May, 1863, there have been but few 

 additions to the group. Nor have the then debatable points been settled
