ish or yellow, edged with black. Subventral ridges oblique, prominent, 

 pale, but margined with black and bearing many setre. Anal plate ob- 

 scure, blackish. Between the setse are numerous small black dots bear- 

 ing still more minute setse. A row of four ventral setiferous black spots 

 on each segment anterior to the legs and six medio- ventral segmentary 

 round orange spots posterior to the feet on joints 6 to lo. Forms a 

 reticular cocoon of yellow silk. 



Macrophya bilineata MacGillivray. 



Head whitish, eye black, a large black patch on vertex, neat, al- 

 most pyriform. Body segments 7-annulated with minute black setas on 

 the second and fourth annulets. Body tapering a little posteriorly, 

 straight or curled spirally, feet on joints 6 to 13. Whitish, translucent, 

 not shining, appearing green from the food except subventrally ; a faint 

 black lateral shade bounding the apparently green area ; a single small 

 sooty black suranal spot. Tracheae distinct ; thoracic feet clear with 

 brown tips. Width of heart 1.8 mm. 



Ultimate stage. — Annulate, slightly shining, all immaculate, waxy, 

 whitish emerald green. Head slightly testaceous, eye black, no marks. 

 Enters the ground. 



Food-plants. — Viburmun opulus diwd V. cassinoides. 



Macrophya mixta MacGillivray. 



Head reddish on vertex, eye black, no marks; width 1.8 mm. 

 Body waxy greenish, 7-annulate, no marks. Another example had a 

 dusky lateral shade defining the dorsal color which appears darker than 

 the subventral region on account of the food showing by transparency. 

 Ultimate stage like the preceding species. 



Food-plant. — Viburnum opulus. 



These two species of Macrophya occurred together and only one 

 example of each was bred. I suspect that they are not specifically 

 distinct. 



Tenth redo remota MacGillivray. 



Resembles T. cressoni, but less yellowish green, the skin being 

 colorless and only green from the food ; no subdorsal band of fat, at 

 most only a few scattered granules. Widths of head observed .6, .8, 

 1.4, 1.8, 2.2 mm. 



The egg forms a regular elliptical swelling near the middle of a 

 leaf, 2x 1.5 mm., under the lower epidermis, the saw-cut on the upper 

 side. 



Larva. — Head large, prominent, with grooves before the vertices
