SYNOPSIS OF LARV.K (THAT OF S. AI'ICALIS UNKNOWN). 



A. Witli two or three large high dorsal al)iluminal forked tubercles. 



Head strij>ed ; sides of second aud third thoracic segments greenish ; a whitish dorsal patch lietweeu the 

 lirst and second dorsal tnbercles; conspicuons V-shaped marli just behind the second tnbiTcle. 



S. ipomece 



Three high tubercles, higher than in the other species, especially the first; body ujore or less russet, 

 with no green patches. Head not striped S.UiitiiioideK 



Only two dorsal tubercles, thiit on fifth abdominal segment wanting; body russet or very dark green on 

 sides of thoracic segments behind the spiracles. Head not striped. V-shaped dorsal mark silvery 

 white and conspicuous ,S'. unicornis 



Three small dorsal tubercles, sides of thoracic segments green ; V-shaped uuirk absent (Dyar) . . S. hadia 



Resembles larva of leptinoidea in coloring, but structurally more like ipomea: AVheu at rest greatly 

 hunched anteriorly, and the furcate prominence on first abdominal segment is ■very long (Thaster). 

 An additional one on preceding segment (Dyar) ,S'. eximia 



B. First abdominal segment greatly swollen above and ou the sides; hairs of the other species represented 



by very stout, blunt spines. 

 Dorsal hump coral-red ; spines black ; body with blacli and white lines before and behind first abdominal 

 segment ; yellow ochcrous along the back ,*>. cunciniia 



I add Dr. Dyar's synopsis, as he Las seeu the hirv;e of eximia. I have changed tlie name 

 nitida to badia.'
