of vasiforni orifice are two crescent-shaped thickenings of terguni, and 

 bet\ve(Mi it and the candal niar<»'in of case there is a shallow furrow. 

 On the ventral surface the unseg-niented reduced legs are seen; the 

 antennie are short, stout, unsegmented, and with a spine at apex: eye- 

 spots large, dark red. 



There is considerable variation in iimount of dorsal secretion and in 

 the number of pores and papilhe. 



Adidt fcinale. — Length, about 1.88 nun.; fore wing, 1.27 nun. by 0.5 

 mm.; hind wing, 1.03 by 0.-13 mm.; hind tarsus, 0.25 nun.; proximal 

 segment, 0.15 mm.; tibia, 0.1:5 mm.; main vein, seven-eighths length 

 of Aving; flexure, about midway between base and apex of wing; 

 be^'ond the tiexure the vein fades out. Color, abdomen, pale a'cUow, 

 head and thorax darker yellow to pale dusky; legs, antennae almost 

 white; wings immaculate, folded so that l)asal veinlet is not seen; fore 

 wing with a conspicuous anal fold. p]\'es dark reddish brown; in live 

 specimens each is separated into two parts b}^ a wedge-shaped band of 

 white wax granules; in the mounted specimen the wax is dissolved 

 away and the eyes are apparenth' only constricted. Antenme and 

 mentum usual. Vasiform orifice obscured. Genitalia sharply conical, 

 brownish in color, otherwise ordinary. Insect bred from pupa case 

 on Ceanothus calif ornicus. 



Male. — (Bred from pupa case on Rvlms vitifoUus.) Length, 1.1 

 mm.; fore wing, 1.1 mm. l)}^ O.-tl: nmi.; hind wnng, 0.1> mm. by 0.37 

 mm. ; hind tarsus, 0.25 mm. : middle tarsus, 0.21 mm. ; proximal tarsus, 

 0.23 mm.; hind tibia, 0.43 mm.; middle tibia, 0.3 mm.; proximal tibia, 

 0.03 mm.; proximal segment, 0.16 mm." Color as in female. Men- 

 tum duskv, nearly ])lack. Genitalia, usual. In other respects (essen-

The pupa cases were first collected in ^Nlarch. larvw on April l(i. 

 Adults were seen flying at this time, but the first to emerge from the 

 segregated cases came out on May 29.

This species is found on the under sides of the leaves and has been 

 collected in the following localities: On Ceanothus calif ornicus^ from 

 the Santa Cruz and Santa Moreno ranges; on Yerlia Santa, from 

 King's Mountain; on Buhus citlfoli(it<, from the Santa Clara A'alley and 

 Alameda; on Rhamnus californica, from the Santa Cruz and Santa 

 Moreno ranges and Santa Clara Valley; on Clematis ligusticifolia.^ 

 Opidaxfcr capitaiiix^ and Syiit^thoricarjX'S racemo.sus, from the Santa 

 Clara Valley, and from Queixus densiflora^ from Kings Mountain. 

 There are seldom mori^ th;in two or three specimens on a leaf; they are 

 usually found together with ^1. coi'oiudux and A. yvlatinosiis. 



"There is considerable variation in the number of large dorsal pores and papilla.
