Type, collection of George Franck, Esq. 



This insect forms a connecting link between 6 1 . kalmi<z and S. 

 chersis, having in part of its primaries the peculiar yellowish 

 brown of the former, and besides the light gray, as well the entire 

 shape of wings of the latter. 



I tak.e great pleasure in naming it after my friend, Mr. George 

 Franck, of Brooklyn, a well-known lepidopterist. 



Sphinx coloradus Smith. 



This is only a local (Colorado) variation of my .5". dollii, Pap. 

 i, p. 149, from Arizona. Mr. D. Bruce, in the last few years, 

 has caught quite a number of this form, which, on the average, 

 is soirfewhat larger than the typical. In the type the whitish 

 space along costa and cell, as well as the black dashes between 

 veins, are less pronounced, and the short, black, transverse, sub- 

 marginal line between veins 2-5 is absent. In all other respects 

 the insects tally.
