192 THE CANADIAN ENTOMOLOGIST. 



[132.] 180. Rhizotrogus fervens Gyll. — Two specimens taken in 

 Lat. 54 ; a variety in Canada.by Dr. Bigsby. [Synonymous with Lach- 

 nosterna fusca Frohl ; the common May Beetle, or Cockchafer, of Canada. 

 " A very common and, through Atlantic America, widely extended 'species, 

 embracing several races, to which, however, no definite characters can be 

 given." (Le Conte). For description and figure see Harris's Injurious 

 Insects, page 30.] 



[133. J 181. Rhizotrogus Drakti Kirby. — Length of the body 9^ 

 to \i%. lines. A single specimen taken in the journey from New York to 

 Cumberland-house. Varieties B and C, by Mr. Drake in Massachusetts. 



This species is extremely similar to the last, it differs principally in 

 having the sides of the scutellum more thickly punctured, the ridges of the 

 elytra, except the sutural one, are scarcely discoverable, and the podex 

 larger and rounder at the apex : the tarsi also are longer in proportion : 

 the knob of the antennae in all the specimens is longer. 



B. Much larger, and the elytra appear somewhat more thickly punc- 

 tured, but it is scarcely distinct. 



C. Like A, but the ridges of the elytra are all discernible.'. [A race of 

 the preceding species.] 



DESCRIPTION OF A SPECIES OF AGROTIS FROM CANADA. 



BY AUG. R. GROTE, DEMOPOLIS, ALA. 



Agrotis represses, Grote. Hind tibiae with two, middle tibiae with one 

 pair of spurs ; fore legs unarmed. Palpi prominent, porrect ; 3rd joint 

 elongated. Body somewhat flattened, much as in A. dandestina. 

 Squamation lustrous, silky. Unicolorous pale testaceous or greyish- 

 brown. Fore wings and thorax concolorous ; the first are without mark- 

 ings, except a short dark dash on the cell in place of the orbicular, and 

 two similar superposed marks at the extremity of the cell, in place of 

 the reniform spot. Three pale ante-apical dots on costa. Veins subobso- 

 letely marked with darker scales. Secondaries pale with a testaceous 

 tinge, darker shaded outwardly. Beneath paler, powdered with greyish 

 and brownish scales ; faint traces of discal marks. Caputal scales dark 

 testaceous. Antennae simple. Exps. 35 m. m. Length of body, 15 m. m. 



Appears nearest allied to A. brunneicollis and A. dandestina. Smaller 

 than the latter, without the lateral abdominal dots, and with longer palpi 

 and obliterate ornamentation of the primaries above.
