contain fat granules. In some examples they are broad and the dark 
markings diffuse and pale. No bloom or white down. 
Stage IX. _(Ultimate.) Exactly as in the last stage except that the 
dorsal pale annulets are light blue instead of greenish gray, the black is 
bluish rather than olivaceous and the skin is very slightly more shiny. 
Head 2.5 mm. The larvae bore in wood to pupate. 
Food-plant _Dogwood ( Cornus alternifolid). 
Harpiphorus varianus Norton. 
Described by me (Can. Ent., xxvii, 196) as H. tarsatus. The 
flies of these two species are occasionally alike in color, as Mr. Harring¬ 
ton indicates, but Mr. MacGillivray has separated them by the structure 
of the female saw-guide and saw. The larvae are abundantly distinct. 
Harpiphorus versicolor Norton. 
Eggs. _About three laid side by side under the lower epidermis 
from above ; a short row nearly parallel to a side vein ; 1.5 X *6 mrn -» 
swelling the leaf; faintly yellowish with a green cential area. 
Stage /. — Head pale brown, eye black; width .33 mm. Body 
curled, whitish, rather opaque, without bloom. Food green in the 
slightly enlarged thorax. 
Stage //.—Head pale brownish, darker over the vertex ; width .5 
mm. Body annulate, colorless or greenish from food, mealy white. 
Stage III. _Head black, mealy only in a band across between the 
eyes ; width .8 mm. Body yellow, well covered with the white mealy 
secretion. 
Stage IV. —The same. Width of head 1.1 mm. 
Stage V.— Width of head 1.5 mm. 
Stage VI— Head black, slightly mealy except the eye and mouth ; 
width 2.1 mm. Body coarsely 6-annulate, mealy or short woolly to and 
including the subventral folds ; no marks whatever ; feet on joints 6 to 
13. Thorax slightly enlarged. 
Differs at once from H. varianus , in being without the black anal 
plate. 
Stage VII. —(Ultimate.) Head black, yellow below the eyes, no 
bloom; width 1.5 or 2.1 mm. Body shining, the subventral folds and venter 
ocher yellow, dorsum blue gray, marked with leaden black on annulets i r 
3, 5 and 6 subdorsally and on all the annulets laterally, leaving a dor¬ 
sal and a subdorsal line of the ground color connected on annulets 2 and 
4. The lower end of this dorsal color is incised before the spiracle by 
the upper yellow subventral fold. Feet all pale ; bores in wood. Found 
on Cornus at Greenwood Lake, N. J.
