 color. The specific name is suggested by Dr. Skinner, but it 

 gives me pleasure in adopting the suggestion to testify my ap- 

 preciation of Mr. Laurent as a good collector and as a good 

 fellow.

LEPIDOPTERA-HETEROCERA (Moths). 

 By Prof. JOHN B. SMITH, New Brunswick, N. J. 



We may follow the series treated in the last number by the 

 true Bombycidae, using Bombyx mori, the well-known silk worm 

 moth, as the type of the family, as it is the only species in our 

 fauna referable to it. Strictly speaking, indeed, the silk worm is 

 not a member of our fauna at all, but it has been domesticated, 

 as we have domesticated so many animals for the benefit of man. 



In this species we find a small, but distinct frenulum, best de- 

 veloped in the male, but evident also in the female. Vein 5 of 

 both wings arises from the cross-vein almost midway between 4

 forms that follow. The wings are quite large, the primaries dis- 

 tinctly falcate, the secondaries proportionate. The head is small, 

 retracted, the antennae pectinated in both sexes, the tongue ob-
