figure of one of the British Museum clintonii and believe it to be 
obliquata G. & R.; it lacks the pale basal space and the subterminal 
dashes which characterize true clintonti. Sir Geo. Hampson was cor- 
rect in associating the Brit. Museum species with atomaria Wlk. but 
erred in stating to Beutenmueller regarding plagiata Wlk. that “as 
far as the condition of the types allows me to judge, this is the same 
as Parorgyia clintonii G. & R.” (Bull. Am. Mus. N. Hist. IX, 210, 
1897). Plagiata Wlk. must now be considered identical with leucos- 
_ tigma A. & S. and the true clintonii was evidently unknown to Hamp- 
son. Beutenmueller’s synonymy, as published in the above reference, 
has been followed in Dyar’s list without any further attempt on the 
latter author’s part to verify the truth of this statement. Riley, who 
doubtfully placed clintonii as a synonym of achatina A. & S., came 
very much nearer the mark, and it is still quite possible that the two 
may be but forms of a single species. 
Packard’s reference of this species to leucophaea A. & S. is due to 
an entire misidentification; the larvae are totally different. 
We recognize two subspecies or geographical races, the typical 
basiflava basiflava occurring in the New England States, New York, 
Pennsylvania and as far south as Maryland, whilst a second form, 
which we have referred to under achatina as the ‘Florida form”, 
occurs in Florida and the Southern Atlantic States as far north as N. 
Carolina; we characterize this below.
