iiiarkinos. Cervical shield large, dark with pale bisecting- line. The 

 spiracle and tubercle iv together show as a black spot. 



Stage YIL — Head 2.8 mm. Cervical shield shining black with pale 

 dorsal and subdorsal lines. Dorsal space pale with faint diamond- 

 shaped marks. Sides nearlj^ black, lighter streaked above and on sub- 

 ventral fold. Tubercles large, black, shining. Head brown, reticu- 

 late in l)lack with the usual vertical bands. 



FELTIA VOLUBILIS Grote. 



One specimen, June 10. This seems to me only an extreme form 

 of cancoaveren-slx. 



FELTIA ^NEIPENNIS Grote. 



Three specimens, June 16, 23, Jul}- 2, which I refer with some 

 doubt to this species. They are not of the faded brown which is 

 usual, but the colors are darker and more contrasted. On the other 

 hand the}^ are smoother than vancouverensis and less contrastingly 

 marked. 



Egg. — Spheroidal, the base narrowly flat. Ribs about 10, diminish- 

 ing by alternation at upper third, crowned and separated by the ver- 

 tical reticulations, which with the cross-stria? form nearly square cells, 

 rather faint, not raised. The ribs bend at the edge of vertex and 

 become smaller, but run right, to the micropyler elevation with its 

 circle of pyriform cells. Pale yellow; diameter, 0.8 mm. 



Stage I. — Head round, bilobed, shining black; cervical shield black. 

 Body robust, short, joint 12 not enlarged, feet of joints 7 and 8 short. 

 Tubercles round, black, normal, elevated, seta? long, pale at tips, with 

 enlarged glandular ends. Body sordid whitish, unmarked. 



Stage IT. — Head bilobed, the lobes blackish, sutures and clypeus 

 pale; width, 0.15 mm. Cervical shield semicircular, black, as also 

 the anal plate, tubercles, and thoracic feet. Bodj' robust, short, joint 

 12 not enlarged, pale green, no marks; abdominal feet pale. The 

 larva is sluggish and fat, a little narrowed at the ends. 



Stage II L — Head full, sordid whitish, the apices of the lobes smoky; 

 tubercles dark; width, 0.6 nnn. Body short, robust, a little flattened, 

 pale, shaded with ])rown, leaving dorsal subdorsal, lateral, and Ijroad 

 stigmatal l)ands of the ground color, brown edged. Cervical shield 

 smoky, trilineate in pale. Tubercles rather large, blackish, slight]}' 

 elevated; seta? pale, minutely bulbous tipped; feet of joints T and 8 

 still short. 



Stage IV. — Head rounded, the apex in joint 2, pale brown, a large, 

 dark brown mark on the face of each lobe; width, 1.1 mm. Body 

 robust, quadrangularly flattened, joint 12 gently enlarged. Sordid 

 brown; dorsum broadly pale to tubercle ii, with faint indications of 

 lattice marking. Sides dark, inclosing very narrow, scarcely' percep-
