38 THE CANADIAN ENTOMOLOGIST. 



have Trans-Atlantic specimens of both species, and the American form 

 differs from either of them fully as much as they do from each other. The 

 European mortisaga and siftiilis seem to vary much within specific limits ; 

 and had my American forms occurred in localities remote from one 

 another, species-makers would doubtless have given each a distinct 

 name. One has the thorax smooth, sparsely pitted, and the elytra 

 sulco-striate ; another has the former uneven with shallow depressions, 

 and also the elytra similarly sculptured and without the faintest appear- 

 ance of striation or indentation ; while the third is intermediate. From 

 the material before me I would say that the Virginia insect is as likely to 

 be mortisaga as sitnilis, with the chances in favor of some other of the 

 numerous European sjDecies. 



The species of Donacia are greatly confused, and as sixteen new 

 species have been added since the last Revision (by Crotch), fourteen of 

 which were described in Europe, a new synopsis accompanied by good 

 descriptions is greatly desired. The same may be said of several other 

 genera, especially Brachynus, Bembidium, Heterocerus and Lachnosterna, 

 for all of which it is almost useless to exchange. 



GLAUCOPTERYX CUMATILIS AND MAGNOLIATA. 



BY J. ALSTON MOFFAT, HAMILTON, ONT. 

 CUMATILIS, G. «Sc R. 



Color of front wings greenish white, with heavy black markings ; in 

 one light the whole front wing is suffused with a rich smoky brown, whilst 

 in another it has a beautiful green gloss deepest in the centre. Hind 

 wings brownish gray. Two specimens. 



Magnoliata, Guen. 



Color of front wings white with black and light gray markings. Five 

 specimens, varying considerably from one another. Hind wings white, 

 more or less pure. 



The markings in both forms are identical, but differing greatly in depth 

 and distinctness. In Cumatilis there is a sinuate line across the centre 

 of the front wing of a buff color, quite distinct. In Alagnoliata it is so 

 faint as to be scarcely perceptible. Magnoliata has a conspicuous black
