being taken on basswood at Ottawa, Ont. Although de- 

 scribed from the North, it has been collected in Maryland 

 as I have been informed by W. L. McAtee, and a specimen 

 was taken at a light in Mississippi. The rather large 

 C. nava may possibly occur, however, and is included in the 

 following key. 



Key to the species of Catonia* 



Front conspicuously transversely banded 1 



1. Elytra unicolorous testaceous brown, nervures impunctate, frons 



banded impunctata Fitch 



Elytra unicolorous testaceous brown, nervures impunctate, frons 



entirely black dimidiata Van D. 



Elytra brownish and banded, nervures dotted with black. All 

 small species 2 



2. Frons black with broad transverse median ivory white band, 

 clypeus only slightly narrowed towards base and with an in- 

 definite whitish band crossing the base picta Van D. 



Frons black with a similar broad band, clypeus immaculate, more 



decidedly narrowed towards base cinctifrons Fitch 



Frons fulvous with this band only half as wide..bicinctura Van D. 



3. Larger, elytral areoles with numerous incomplete transverse vein- 

 lets, apex of mesonotum with a pair of ocellated black points, 

 grisea Van D. 



4. A larger species with the frons less definitely banded and the 

 clypeus white marked with fuscous nava Say 



Catonia picta VAN DUZEE 

 (1908 Pro. Acad. Sci. Phila., lix, p. 481). 



Recorded from N. J., N. C., Ga., and Fla. 



Its small size, strongly marked front, and slightly macu- 

 lated elytra, showing obscure transverse banding, distin- 

 guish this species. 



Testaceous-grey, frons black with a broad median white band, 

 mesonotum a dirty rufous, elytra obscurely banded. 



General color above testaceous-grey, beneath pale fulvous. Vertex 

 short, broader than long, but feebly advanced before the eyes, obtusely 

 angled before ; margins and middle carinate. Front broad, but slightly 

 narrowed at base, deep black with a broad median transverse band of 



*Metcalf has since published descriptions of four new species and as the writer has 

 not seen these species no attempt has been made to fit them into the above key. The 

 original descriptions are quoted to make this publication as complete as possible.
