NORTH AMERICAK LEPIDOPTERA. 141 



larva? have been carefully figured iu 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 four species belonging to our fauna — posticatns being 

 excluded as not referable thereto; satel/itia and lycaon 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 inuer margin to costa before apex; ground color 

 olive green. 

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



broader liiiiiei. 



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

 Primaries without the bands above described. 

 Ground color olive green, secondaries very pale bluisli greeu on disc. 



paiiiloriis. 

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



There are two distinct types of luaculation. Vitis and liitiiei 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. Liniiei 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. 



Pavdorus and achemon lack the stripes ; they have a somewhat 

 triangular 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 diffuse shade from costa beyond 

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

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

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

 structural difference.
