1228 THE BUTTERFLIES OF NEW ENGLA>rD. 



Table of genera of Papilioninae, based on the egg. 



Egg more or less bcBmearpd with a secretion on layinf;. 



Egg heavily besmeared, laid in small clusters, the height and width ot the egg equal, not- 

 withstanding the truncate base Laertias- 



EgfTlightlybesineareii, laid singly, the form perfectly globular but for the considerably 



truncate base Heraclldes. 



Egg with no perceptible adventitious covering, laid singly. 

 Egg distinctly broader than high. 



Cells of the tnicery with granular raised points Jasoniades. 



Cells of the tracery smooth or nearly so Euphoeades. 



Egg barely broader thau high Papllio. 



(Iphiclides not examined.) 



Table of genera, based on the caterpillar at birth. 



No simple papillae bearing a single bristle arranged upon the dorsum in subdorsal series, in any 

 striking contrast to the others from their smaller size. 



All abdominal papillae above the spiracles bearing single and simple bristles Laertias. 



Most of the abdominal papillae above the spiracles compound, bearing many bristles many 



of which are distinctly forked apically Iphiclldea. 



A subdorsal series of simple papillae, each bearing a single bristle, strikingly dififerent in size 

 and simplicity from the compound tubercles of the adjacent rows. 

 Bristles of the supralateral or lateral series three or four in number and, as well as the 

 tubercles themselves, sensibly diminishing in importance toward the middle from either 

 end of the body; bristles of the supra- and infrastigmatal series comparatively few, com- 

 paratively distant from the spiracles, and rather closely clustered. 

 Bristles of subdorsal series much shorter than the others ; most of the bristles of the 

 upper half of the body distinctly clubbed; second series from the mediodorsal line 



distinctly lateral Jasoniades. 



Bristles of subdorsal series as long as the others ; the bristles of upper half of body very 



faintly enlarged at tip; second series from the mediodorsal line supral.iteral 



Enphoeades. 

 Bristles of the supralateral series six to eight in number and hardly diminishing in impor- 

 tance in the middle of the body, as do the tubercles they rest upon ; bristles of the supra- 

 and infrastigmatal series numerous, loosely clustered, approximating the spiracles so as 

 ahnost to surround them. 

 Suprastigmatal tubercles of first thoracic segment conspicuously larger than the rest, 

 nearly doubling the width of the segment, their base half as thick as the segment. . . . 



Heraclides. 



Suprastigmatal tubercles of first thoracic segment not conspicuously larger than the 



others, their base not one-fourth as thick as the segment Papilio. 



Table of genera, based on the mature caterpillar. 



Body furnished with a .series of large fleshy filaments on the sides Laertias. 



Body without lateral filameuts. 



Hinder thoracic segments distinctly larger than the anterior abdominal segments. 

 Third thoracic segment with no transverse dorsal ridge. 



Third thoracic segment with no central markings ; first abdominal segment marked 

 in front with a transverse, dorsal stripe ; other abdominal segments with trans- 

 verse linear markings Iphiclides. 



Third thoracic segment with a p.air of conspicuous compound ocelli in the middle; 

 first abdominal segment marked behind with a transverse dorsal stripe; no trans- 

 ver.se markings on the remaining abdominal segments. 



First abdominal segment with no large, bright patches Jasoniades. 



First abdominal segment with a pair of laterodorsal, black-edged, bright 



patches, nearly as large as the ocelli in front of them Kuphoeades. 



Third thoracic segment with a transverse, arcuate, dorsal ridge Heraclides. 



Hinder thoracic segments scarcely larger than the succeeding segments. Body conspicu- 

 ously and transversely banded throughout with black Papilio.
