NOCTURNAL LEPIDOPTERA FOUND IN CANADA. 

 Part II. HomopteridjE.

8BCBETAEY TO THE ENTOMOLOGICAL SOCIETY OV CANADA. 



In a former number of the Canadian Journal (vol. viii. 1-16, Feb., 

 1863) descriptions of all the then known species of the genus Catocala 

 found in Canada and the neighbouring States, were published with a 

 view to assist collectors in naming their species, and to furnish at the 

 same time a contribution to Professor Hincks' contemplated " Fauna 

 Canadensis." A valuable Synopsis of Canadian Arctiadae, by Mr. 

 William Saunders, has since been published (vol. viii. 349-377, Sept., 

 1863) in furtherance of the same objects. The following descriptions 

 of new and previously known species of another family 'of moths 

 (Homopteridge) are now oifered as a further contribution, small though 

 it be, to our limited stock of information respecting the insects of this 

 country. 



QUADRIFIDiE — EXTENSA. 



The section Extensce of the group QuadrifidcB, to which many of 

 our handsomest night-flying moths belong, is divided by M. Guenee 

 into three families, one of which, Polydesmidse, is not represented in 

 America ; of another, Hypogrammidse, only two species are found in 

 the Southern States, but none in Canada ; of the remaining family, 

 Homopteridse, which I now propose to consider, a goodly number of 

 species are found in this country. 



HOMOPTERIDiE. GuCU. 



The members of this family, in their perfect state, may be readily 

 distinguished from all other Noctuidae by the following characteris- 

 tics : — All the wings are broad and nearly alike in colour, wood -brown 

 or the colour of an ordinary withered leaf, and black predominating ; 

 their markings are also similar, the subterminal line forming on the 

 anterior wings two large arcs which unite on the middle of the hind 

 margin, and on the posterior wings one, the space thus enclosed being 

 in several species covered with white or pale green scales. The palpi 

 are long and ascending, with the third joint well developed and linear. 

 The thorax is broad, with the tegulae very large and divergent, cut
