[FLETCHER] DESCRIPTIONS OF CANADIAN BUTTERFLIES 21S 



secondaries, very similar to the underside of the British Columbian 

 P. agricola. The mesial band is d.uU yellow, inconspicuous, angled and 

 irregular, composed of the same squarish spats as in manitoha. These 

 are perhaps normally 8 in number as in manitoba when all are present, 

 but this is seldom the case in this species, I have only eight specimens 

 before me at the present time : in one of these there are seven spots and 

 a trace of the eighth ; in one specimen there are seven, in five six, and 

 in one five. The spots of the lower portion of the band, when present 

 and of full size, confluent or nearly so, the two spots at the angle of the 

 band usually smaller than the others. The large V-shaped spot, so 

 conspicuous in tlie cell of manitoha, is inconspicuous and frequently 

 absent. The spot at the base of the submedian interspace seldom pre- 

 sent or very small. In the males the light colour pf the spots has a 

 tendency to run out along the veins, both towards the margin and to 

 the basic of the wings, in the same way as in P. uncas. 



Alar expanse, males 28-31 mm., females 30-33 mm. 



Locality: Up to the present time I have only taken this species at 

 Nepigon, Ont., and Sudbury, Ont. Specimens sent to Mr. Henry 

 Edwards many years ago were at first named by him Pamphila sylva- 

 noides, but he subsequently wrote to me : " Your northern Ontario 

 Pamphila is not sylvanoides, but must come nearer to one of the forms 

 of comma, such as manitoba or Colorado; but the underside shows that 

 it is quite distinct from either of these." 



P. manitohoides occurs at Nepigon, as stated abave, from the third 

 week in June until the middle of July. A month or six weeks later than 

 this the true P. manitoha appears, which is a rather larger insect, with 

 a greenish tinge on the underside and distinct silvery white markings. 

 The eggs of P. manitohoides hatch about a fortnight after they are laid, 

 but, as has been shown by the Eev. T. W. Fyles [Canadian Entomologist 

 XXVII (1895), p. 346 J, the eggs of manitoha laid in August do not hatch 

 until the fallowing spring. The larva of manitohoides, as described by 

 me in the Report of the Entomological Society for 1888, does not quite 

 agree with Dr. Fyles's description of P. manitoha. I have no idea that 

 this species is very ciosely related to P. manitoha, and the name was only 

 given to indicate a somewhat close resemblance on the upper side to that 

 species. I did not intend, when publisihing the description of the larva, 

 that the name manitohoides should stand, and particularly mentioned 

 in the article referred to, that, as I did not wish to cause confusion by 

 naming what might prove to be a described species in a difficult genus 

 which I had not specially studied, I refrained from further describing 

 the perfect insect. Unfortunately, this precaution seems to have been 

 unavailing, for several have written to me for further information on
