anterior more obtusely ; dorsum arched, the highest point a little before 

 the middle ; tail quadrate. Ridges low, not prominent, the subventral 

 shorter than the lateral. Body smooth, setae still visible. Depressed 

 spaces large, the latticed ridges beginning to be more than one granule 

 wide, those of the subventral ridge subpapillose or slightly cleft. Color 

 whitish, green only in front ; dorsal red patch large, covering joints 6 

 to 10, pentagonal, truncate before, widest at joint 8 where it reaches 

 the lower border of the depressed space (4), tapering behind nearly to 

 a point ; a central pale patch and distinct yellow border, produced as a 

 subdorsal line behind, but not in front. Length, 2.6 to 3.7 mm. 



StageV. — (Plate VIII, fig. 9). Page 170, lines 31, 32, 39, 40 and page 

 171 lines 1 and 2, omit all reference to the coloration and read : green 

 in front, the dorsal patch larger than before, more distinctly angled and 

 pointed in front ; it covers six depressed spaces and reaches on the sides 

 to depressed space (5). There may be a small red patch on joint 3. 



Stage VI. — (Plate VIII, fig. 10). Page 171, lines 8 to 13, omit all 

 referring to the coloration and read : A large dorsal purplish red patch 

 almost exactly as in the mature larva, but not reaching either extremity. 

 Line 7 for "may have" read "has." 



Stage VIII. — (Plate VIII, fig. n). Page 171, lines 27 and 28, omit 

 the words " from narrow to broad and." Omit also the references to 

 the plate and the foot-note at bottom of page. Lines 36 and 37, omit 

 " thus forming a large blurred red cross." There is no particular re- 

 semblance to a cross in T. pallida. 



This Journal, IV, pi. VI, figs. 5, 6 and 7 represent T. testacea not 

 T. pallida. Compare the accompanying plate (Plate VIII, figs 8, 10 and 

 it) for the correct representation of T. pallida. Figs. 3 and 4 repre- 

 sent H. flexuosa not T. pallida.

This Journal, IV, 187. Add the following description of the freshly 

 laid egg : Large, colorless, a little milky whitish, shining; 1.8 x 41. 

 mm. and almost without thickness (about .1 mm.); reticulations dis- 

 tinct, raised, whiter than the egg. Hatches in not less than ten days. 



Stage I. — Mr. Joutel has seen this stage with the subdorsal horns of 

 joints 6 to 12 degenerate, the rest normal. The degenerate horns had
