and antenna' have disappeared from view, and the mouthparts are 

 much smaher. In other respects as in stage 1. 



Pupa-case. — Size, 1.33 by 1 mm.; broadl}' elliptical, very convex, 

 slightlv narrower at the cephalic region; caudal end truncate, emar- 

 ginate, and bent abruptly to the leaf. Color smoky brown, sometimes 

 yellow, darker over the developing pupa or parasite; leg outlines con- 

 spicuous. The entire dorsum is rugose, and marked with more or 

 less radially arranged thickenings or reticulations, which show as 

 minute, blackish dots; on each segment from the vasiform orifice to 

 the mouthparts there are two parallel rows of depressions of irregular 

 outline, bounded cephalad by the margin of the preceding segment. 

 Case very convex and with a medio-dorsal keel ; there is neither dor- 

 sal nor lateral secretion, and the vertical fringe is very short. The 

 marginal rim is lacking, and the wax tubes are not evident except at 

 extreme margin, crenulations shallow and irregular; abdominal su- 

 tures conspicuous, the posterior ones reflexed caudad. The cephalo- 

 marginal hairs are minute, the caudal and latero-caudal hairs are 

 present, but their relative lengths are reversed, the latero-caudal being 

 much the longer. Just within the caudal margin is a pair of short, 

 delicate hairs, and a similar pair is found at vasiform orifice. Scat- 

 tered over the dorsum are a number of small pores. Vasiform orifice 

 outlined by a dark rim; subovate almost as l)road as long, the distal 

 end bluntly rounded, lateral margins with corrugations, or folds, 

 extendingdownward and inward; operculum one-half length of orifice, 

 sub-semielliptical. cephalic margin straight, caudal end usually trun- 

 cate but occasionally rounded and somewhat pointed; color brown; 

 dorsal surface covered with closely set, minute hairs; lingula nearl}^ 

 the length of orifice, cylindrical, the distal two-fifths somewhat enlarged 

 and arrow-shaped, thickly setose, and terminating in two straight 

 setse, which reach beyond the caudal end of orifice; a pair of setai is 

 also found on the lateral margins. Cephalad of the orifice is a thick- 

 ened prolongation of the outline of the lingula, which reaches nearly 

 to the two crescent-shaped thickenings intergum, and caudad a narrow 

 furrow extends from orifice to margin of case. Rudimentary legs 

 distinct on the ventral surface. Eyespots divided, the anterior lobe 

 smaller, color bright red. 



Adidt female. — Length of body, 1.8 mm.; fore-wing, 1.7 by 0.8 

 mm.; hind wing, 1.6 b}^ 0.6 mm.; hind tarsus, 0.25; color, yellow 

 with strongly chitinized places which make brown markings; segment 

 1 of abdomen has three longitudinal stripes; between segments 1 and 

 2, on line of suture, there is a transverse stripe; segment 2 has two 

 lateral longitudinal curved bands the length of segment, between 

 these are two sub-crescent-shaped, lighter colored patches, not as long 

 as the lateral bands, with concave side of the crescents townrd the 

 median line; segments 3 and 4 have each two l)road, transverse bands
