NORTH AMERICAN LEPIDOPTERA. 141 



larvre have been carefully figured in all stages by Prof. Riley. 

 These figures have been used again and again until the larvae are 

 about as well known as any. 



We have fi)ur species belonging to our fauna — posticatus being 

 excluded as not referable thereto ; satel/itia and lycaori are also ex- 

 cluded as not synonymous with pandorus. 



Primaries with a longitudinal band from base to apex and an oblique transverse 

 hand from middle of inner margin to costa before apex; ground color 

 olive green. 

 Outer margin of secondaries fuscous, except at anal angle; larger, primaries 



broader liniiei. 



Outer margin of secondaries pinkish red ; smaller, primaries narrower, vitis. 

 Primaries without the bands above described. 

 Ground color olive green, secondaries very pale bluish green on disc. 



paiKlorus. 

 Ground color very pale fawn gray; secondaries red on disc aolieiiioii. 



There are two distinct types of niaculation. Vitis and linnei agree 

 in the ground color of olive green, with a broad longitudinal pale 

 streak, crossed by one of the same nature from the middle of inner 

 margin to the costa near the apex. Linnei is larger, broader winged, 

 more sordid in appearance ; the outer margin of secondaries not red, 

 except at anal angle ; vitis is smaller, narrower winged, the outer 

 margin less arcuate, maculation much more distinct ; the secondaries 

 have the outer margin pink. 



Pandorus and aehemon lack the stripes ; they have a somewhat 

 ti'iangular spot before the apex on costa, another near the anal angle 

 on inner margin ; a quadrate patch at about the middle of inner 

 margin and a rather larger, more difl^use shade from costa beyond 

 middle, extending downward to about vein 3. Pandorus has the 

 ground color a very pale olive green, while aehemon has it reddish 

 or fawn gray. The species are thus very distinct, irrespective of any 

 structural difference.
