secondaries, very similar to the under side of the British Columbian 

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

 irregular, composed of the same squarish spots as in Manitoba. These 

 are perhaps normally 8 in number, as in Ma?iitoba, 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 the cell of Manitoba, is inconspicuous and frequently absent. The 

 spot at the base of the submedian interspace seldom present or very small. 

 In the males the light colour of the spots has a tendency to run out along 

 the veins, both towards the margin and to the base of the wings, in the 

 same way as in P. tmcas.

 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 

 sylvanoides, 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 ox Colorado; but the under side shows that it 

 is quite distinct from either of these." 



P. Manitoboides occurs at Nepigon, as stated above, from the third 

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

 this the true P. Manitoba appears, which is a rather large insect, with a 

 greenish tinge on the under side and distinct silvery white markings. 

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

 but, as has been shown by the Rev. T. W. Fyles [C.a.nadian Entomol- 

 ogist, XXVII. (1895), p. 346], the eggs of Manitoba laid in August do 

 not hatch until the following spring. The larva of Manitoboides, as 

 described by me in the Report of the Entomological Society for 1888, 

 does not quite agree with Dr. Fyles's description oi P. Manitoba. I have 

 no idea that this species is very closely related to P. Manitoba, and the 

 name was only given to indicate a somewhat close resemblance on the 

 upper side to that species. I did not intend, when publishing the 

 description of the larva, that the name Manitoboides should stand, and 

 particularly mentioned in the article referred to, that, as I did not wish to
