Brownish or creamy-white. Head brown except between antennae. An- 

 tennae with brown dots above. Palpi rather short, brown on sides. Legs 

 whitish, front and middle femora brown inside ; fore tibiae with heavy double 

 brown tuft as in occidentalis, mid tibiae with two tufts. Hind legs entirely 

 whitish, scarcely touched with brown along tibia, at bases of spurs, on their 

 tips, and in dark specimens on tarsi, never conspicuously banded. Inner spur 

 of median pair much less than twice as long as outer. Abdomen brownish at 

 sides. 



Primaries brownish white with a variable sprinkling of dull brown scales 

 darkening the first lobe, apex of second, inner margin and patches of discal area. 

 A dark brown costal dash over base of cleft is incompletely connected with a 

 similar oblicjue, roughly triangular mark before cleft. All dark areas with the 

 rather rough powdering of dark scales evident. Fringes pale ochreous gray, 

 sometimes with a slight pale area before apex of first lobe in cleft but without 

 definite pale pencils. Secondaries gray-brown, shining; fringes cnncolorous. 

 Expanse 22-2S mm. 



Distribution : Described from N. Y. We have a small series from 

 Essex Co. Park, N. J., June and July (Kearfott). 



The type of crctidactyliis is among Fitch's specimens in the Fer- 

 nald collection. It is a 9 in fair condition, rather faded, and bears 

 no type label beyond the general label applied to this group of speci- 

 mens. 



As mentioned under occidentalis, it is not easy to point out definite 

 differences between these two species, though they seem very distinct. 

 The whiter ground color, more roughly powdered dark areas, and 

 relative lengths of the median spurs of the hind tibiae distinguish 

 cretidactyhis, in our judgment. The primaries are relatively broader, 

 but the difference is too slight for actual measurement. A reference 

 to the figures will show this distinction. We have seen no western 

 specimens, and feel that all such records undoubtedly deal with occi- 

 dentalis. 



;\lthough two accounts of early stages have been published under 

 the name we are still in ignorance of the life history of the true creti- 

 dactylus.
