or acute and furving ventrad at apex (spivosn). Segments 

 II to VII of the abdomen with a spiracle on either side. 



Key to the Larv^ of Ebiocera 



1. Head cajisule long and narrow; lateral lobes of the fronto- 



labral sclerite not jironounced ; labrum small. Caudal 

 lobes not developed; hairs around the stigmal field very 

 few (about twenty) but very long. (Genal plate produced 

 into a lobe on the inner cephalic angle; a strong conical 

 tooth on inner face of mandible at about midlength.) 



longicornis Walk. 



Head capsule broader; lateral lobes of the fronto-labral 

 sclerite prominent; labrum well developed. Caudal lobes 

 prominent, one pair being lateral and one pair ventral, 

 bearing fringes of abundant long hairs. 2 



2. Large larvae (fully grown and extended, 40-45 mm. long, 



and 4-5 mm. in diameter) ; lateral lobes of fronto-labral 

 sclerite not hairy; tubercles on labrimi merely roimded; 

 no strong, truncated tooth at mid-length of the mandible 

 on the ventral face; hairs on caudal lobes prominent, 

 reddish. Lateral lobe with a black line which is con- 

 spicuously enlarged at its inner end; ventral lobes with 

 a black line which is forked, Y-shaped, at its inner end. 



spinosa 0. S. 



Smaller, more slender larvse (fully grown and extended, 

 18-26 mm. long, 2 mm. in diameter) ; lateral lobes of the 

 fronto-labral sclerite clothed with abundant long hairs; 

 tubercles on labrum cylindrical, truncated, chitinized; 

 a strong, truncated tooth at mid-length of the man- 

 dible with a smaller one beside it; hairs on caudal 

 lobes abundant but pale, indistinct. Lateral lobe with a 

 black line which is not conspicuously enlarged at its 

 inner end ; ventral lobes with a black line which is en- 

 larged at its inner end, not conspicuously forked.
