dorsal disk ; dorsum without prominent pores or papillae but often 

 with numerous minute pores ; wax secretion in pencils or tufts, 

 often plume-like and decorative ; vasif orm orifice small and nearly 

 circular. 



Only one species has been found in Connecticut.

Technical Series No. 8, Division of Entomology, U. S. Dept. Agr., page

Pupa case about .86 x. 55 mm. broadly oval, narrowed and 

 somewhat pointed cephalad, and broadly rounded caudad ; slightly 

 convex, dark brown or black, with copious, white wax secretions 

 arising from minute pores on dorsal disk and submarginal area, 

 forming plumes or tufts ; those of margin usually bending out- 

 ward, those of dorsum standing upright (see Plate xii, 3). 

 Thoracic tracheal comb distinct, composed usually of four teeth; 

 margin of shallow rounded teeth with suture-like markings extend- 

 ing inward. Vasiform orifice subcircular, somewhat flattened at 

 base and measuring about 56 n x 50 /x ; operculum subtriangular 

 and filling half to two-thirds of the orifice; lingula rudimentary 

 not projecting beyond operculum. 



Adult female : Length about .86 mm. ; fore wing about .91 x 

 .38 mm., white, immaculate. Legs and body uniformly yellow, 

 more or less covered with wax secretion. Eyes reddish brown, 

 constricted. Third antennal segment about equaling in length the 

 fourth, fifth, sixth and seventh combined. 



Male, similar in general appearance though slightly smaller. 



Host, checkerberry or creeping wintergreen, Gaultheria 

 procumbens.

(Aleyrodes in part.) 



Pupa case elliptic, small to medium in size, color varying from 

 whitish to dark brown ; margin toothed with wax tubes moderately 

 developed ; submarginal area not differentiated from dorsal disk ; 

 the former with large papillae or pores ; thoracic tracheal folds 

 rarely distinguishable ; usually a distinct furrow connecting vasi- 

 form orifice with caudal margin; wax secretion appears in form 

 of brittle, white, glassy rods from dorsal pores, and a palisade of 

 white wax elevating the case from the leaf. Vasiform orifice sub- 

 cordate, usually with a notch at caudal end ; operculum about half 

 filling the orifice, transversely elliptic ; lingula exposed, lobed, and 

 usually with a pair of distal hairs or spines. 



Adult with one flexure in radial sector of fore wing; no trace 

 of media except in freshly emerged specimens. Antennae of
