condition. Dr. Hagen considers his micans, 283, 13, to be 

 this species. 



X. elega?is, 279, 10, and latifascia, 279, 12, are the same 

 species ; tlie dark fascia in the former is indistinct in con- 

 sequence of the type being unset. They have 2, 4, 3 spurs, 

 and with Noiidobm pyraloides will form a distinct genus, 

 but the family to which it should be referred seems doubtful. 

 The maxillary palpi do not differ in the sexes, and are similar 

 to those of LeptGcerm, as are also the antennje, but the form 

 of the wings and venation indicate an affinity with the Seri- 

 cosfomides. The numerical arrangement of the spurs is quite 

 aberrant, no other genus being known to possess less spurs 

 on the posterior than on the intermediate tibia. The middle 

 spur on the posterior tibias is placed quite in a line between 

 -the apical ones, and so not in a position that would indicate 

 that one was broken off or abortive. 



A third species from Mysol, Indian Archipelago, is con- 

 tained in the British Museum. 



L. indecisus, 279, 11. The type has 2, 4, 4 spurs. It is 

 of doubtful position. 



Setodes nivea, 281, 3, and S. alhida, Walk., 283, 10, are 

 the same species. May not Mystacides Uwaroivii, Kolenati, 

 Gen. et Spec. Trichop. part 2, p. 249, 1, pi. 8, 24, also belong

S, ochracea, 281, 4.— Erroneously included in the North 

 American list ; the specimen referred to perhaps belono-s to 

 S. iynita, 281, 5. "" 



S.resurgens, 282, 9. -Dr. Hagen thinks that his cine- 

 rascens may be this species. The type has 1, 2, 2 spurs. 



Hydropsyche alternans, 288, 4, and indecisa, 5, are the 

 same species, and Dr. Hagen thinks probably identical with 

 his moroscij 287, 2.
