176 THE CANADIAN ENTOIMOI OGIST 



Scutellum yellow with a complete border of black, slightly over twice as wide as 

 Jong. 



Abdomen slightly shining black, finely scrobiculate ; first and second seg- 

 ments fused, with short black pile on the disc and yellowish pile on the sides; 

 on the sides with an elongate yellow triangle reaching almost to the yellow hind 

 margin, the inner points well separated. Apices of the two following segments 

 increasingly broadly yellow, the yellow on the fourth segment occupying nearly 

 one-third the segment, its anterior angle being bi-convex on each side of the 

 median notch ; pile yellow ; on each side of the third and fourth segments a mod- 

 erately prominent gray pollinose stripe reaching from near the median anterior 

 portion of the segment to a point ibout one-third from the apex and one- fourth 

 from the lateral margins. Hypopygium black, with black pile. In outline the 

 abdomen is slightly narrowed to the apex of the first segment, thence gradually 

 widened to the apex of the fourth, where it is about the same width as at the 

 base. The fifth segment and hypopygium are almost concealed by the fourth 

 segment. 



Legs reddish yellow, the last two or three tarsi joints brownish ; apical half 

 of hind femora and a broad pre-apical band on the hind tibiae brownish. Wings 

 pale brownish anteriorly, hyal'ne posteriorly.

THE CANADIAN SPECIES OE THE GENUS ANOMOGYNA (LEPID.) 



RV J. MCDUNNOUGH, PH.D.,

Omitting the two North American species infimatis Grt. and irrnilis Grt., 

 which may in any case prove to be not strictly congeneric, the genus Anomogyna 

 Stand, has been employed by Hampson (1903, Cat. Lep. Phal. Brit. Mus. IV., 

 588) for a few subarctic European species of Agrotinae of considerable rarity. 



Two of these species, laetabilis Zett. and sincera H.S., have long been 

 placed on our North American lists as occurring in Labrador, presumably on 

 the strength of H. B. Moeschler's identification, who in his time was in receipt 

 of large collections from this region. To North American lepidopterists. how- 

 ever, the species have remained practically unknown until of quite recent years. 



The examination of a series of specimens of this group from the Barnes 

 Collection and that of Mr. K. Bowman of Edmonton, together with specimens 

 contained in the Wolley-Dod and the Canadian National Collections, shows 

 conclusively that there are more species belonging to the grouj) in North America 

 than has been supposed and that these species can be very readily separated from 

 one another by the terminal portion of the claspers (valvse) of the male genitalia. 



As defined by Hampson Anomogyna Stand, (type laetabilis Zett.) differs 

 from Aplcctoidcs Butl. (type condita Gn.) in the absence of spines on the fore 

 tibiae. According to the male genitalia there is evidently a close relationship 

 between the species of Anonioc/yna and certain ones included by Hampson in 

 Aplectoides, notably spcciosa Hbn. and iuipcrita Hbn., and it is a matter of 

 considerable doubt to me whether in the.=e cases the generic separation will hold ;
