lower series which forms a stripe along the sides of the belly, and to the 

 almost immaculate dorsal surface of the larvae which is sharply 

 marked off from the almost black sides. Larvae of E. longicauda and 

 E. mcJanopleura show the same features but owing to their generally 

 having less pigment the lower row of areas is not conspicuous. 



Larvae of E. bislineata and E. imdtiplicata have the lower row of 

 areas lacking and the upper row is very large and pigment accumulates 

 as a broken band between the areas of each upper row so that there is 

 a broken dorsolateral stripe. Larvae of E. vruHiplicata have a much 

 slimmer form, owing to the greater number of costal grooves. 



The following key gives a summary of the above. 



1. No sharp demarcation between the lighter back and the darker 

 sides, 13 costal grooves. 



Lower row present, gray band on sides lucifuga. 



2. A sharp and uninterrupted demarcation between the lighter back 

 and the darker sides, lower row present, 13 costal grooves. Sides 

 black. 



A. Lower row a definite stripe gidtolineata. 



B. Lower row not a definite stripe 



hngicauda and melanopleura. 



3. A sharp but broken demarcation between the lighter back and 

 the darker sides, lower row absent, more than 13 costal grooves. 



hislineata and viidtiplicata. 

 As far as known no two species of any one of these three groups 

 occur together. This renders identification simpler and surer.
