1 8 HARRISON G. DYAR 



till the horns of joints 6 and 7 have only a few or no caltropes. Skin 

 finely clear granular except on the horns. No end spines. Dorsum 

 yellow- or red-shaded, a purple band with white glandular dots 

 and central dorsal line much as in spinuloides, but of different shape. 

 It widens between joints 3 and 4, 4 and 5, then moderately widens 

 on joints 6 and 7, narrows to a slight bordering of the white dorsal 

 line over joint 8, widens behind the horns on 9 and 10, moderately 

 widens between joints u and 12 and ends, joint 13 being green 

 above. A bright red, diffuse, subdorsal band; all the subdorsal 

 horns red. Below, a yellow stripe, narrowly red-edged, waved. 

 Sides green, a row of yellow dashes along the lateral horns, green- 

 edged above; yellow rings on spaces (4). A white line along the 

 subventral edge. Stinging spines short, not numerous. Depressed 

 spaces (i) and (2) represented by white dots, (i) paired and on 

 joints 3-4 and 4-5 also double; depressed space (4) reniform, dis- 

 tinct; slight hollows subventrally; spiracle of joint 5 moved up 

 out of line. Length, 9. 3-1 3 mm. 



Cocoon. Nearly spherical, hard, brown, one end opening like 

 a circular lid on emergence, though there is no sign externally of 

 the crevice of the lid. Spun with a slight veil against a leaf. Diam- 

 eter, 5 mm; length, 7 mm-. 



Pupa. With the characters of the family. Delicate, thin- 

 skinned with the members free. It emerges nearly out of the cocoon 

 when the adult issues. 



Food plants. The red oak is the preferred plant, though the 

 larvae will feed on almost any smooth-leaved tree. I found one 

 on maple at Tryon, the others mostly on oak. In confinement my 

 larvae fed on yellow birch, which they seemed to prefer to soft maple.
