either side of the black dash, especially prominent outwardly. The 

 pale hairs viewed against the body appear blackish. Abdomen reddish, 

 somewhat darker on dorsum, in the female covered with coarse grayish 

 or darker hairs with a few longer dorsal and ventral ones on the pos- 

 terior part of each segment. Hairs proportionally longer and pale in 

 the male, with a few longer dark ones on dorsum and venter as in 

 female. Genitals pale ; feet pale brownish, gray at base becoming black- 

 ish distally, with pale gray appressed pubescence; some longer and 

 darker hairs on underside of femora. Halteres pale yellowish brown 

 at base, darker reddish brown distally. Wings appearing smoky black 

 owing to the numerous dark hairs covering them, fringes long and 

 grayish ; second longitudinal vein arcuate in its latter portion and end- 

 ing immediately beyond apex. Described from several fresh males and 

 females taken in the Stanford Arboretum, and now in the Stanford 

 University Entomological collection. 



Egg .60 mm. long, elongate rounded at both ends, about three and 

 one half times as long as wide, bright orange. 



Mature larva About 10 mm. long (but capable of much greater ex- 

 tension and contraction), width 2 mm.; fusiform, tapering more gradu- 

 ally caudad, somewhat wider than deep. Color bright orange, the 

 stomach showing as dark brown and the Malpighian tubules as deep 

 orange. 14 segments including the head which is very small, and 

 which together with the supernumerary segment is often partially with- 

 drawn into the following segment; segments 6 and 7 widest, n quite 

 slender and appearing compound, 12 small, below n and deeply cleft. 

 Breastbone elongate and varying considerably in form, somewhat in- 

 cised anteriorly. Two large anal spiracles, and lateral ones on seg- 

 ments i and 4 10. Long transverse dorsal and ventral patches of short 

 bristles, best developed anteriorly where they point caudad, posterior 

 spines point cephalad. These bristles are no doubt used to assist in 

 locomotion. 



Pupa Length 5 mm.; stout, orange red; thorax and appendages (with 

 the exception of their free ends which are pale translucent with an 

 orange tinge) darker ; legs reaching nearly to end of 6th abdominal 

 segment and free beyond the 2nd. A slender, curved yellowish-brown 

 breathing tube behind each eye, with a rough, dusky, pointed cocoon- 

 breaker at the base of each antenna at the angle formed by the vertex 

 and frons. Thorax smooth and shining; abdomen duller and rougher; 

 spiracles reduced. 



LIFE HISTORY. 



Owing to the unusually mild spring weather of 1908, Ccci- 

 domyia resinicoloides was probably on the wing- somewhat 

 earlier than usual. The first adult observed was on March
