Vasiform orifice (pi. 53, fig. 11) subcircular in outline, with the rim 

 somewhat thickened. The operculum is small and fills only about 

 the anterior third of it in some specimens, while in others it fills about 

 haK. It tapers caudad. The usual setae latero-cephalad of orifice 

 are absent. Color dark brown to black ; under the microscope vary- 

 ing shades of brown. 



Adult male. — Color yellowish red, shaded with black; forewings 

 maculate as shown in plate 53, figure 14; hindwings unifoi-m pale 

 dusky; legs dusky, excepting the joints, which are yellowish; claspers 

 and tip of abdomen dusky. Eyes and tip of labium brown to black. 

 Antennae absent from the specimens in hand with the exception of 

 one antenna of one specimen. From this it is impossible to make out 

 the relative proportions of the segments, as the specimen is much 

 shrunken. The condition, however, is sufficient to make out that 

 many distinct transverse ring-like imbrications cover the segment. 

 The third segment possesses a long, stout spine. Each clasper 

 (pi. 53, fig. 12) is armed at its extremity with prong-like projections. 

 The two distal ones of these are rather long and acute, whereas the 

 more proximal one is short and conical. A number of spines are 

 present, and the clasper is minutely pubescent. The penis (pi. 53, 

 fig. 13) is enlarged at its distal extremity into a disk-like structure, 

 which seems to have an opening or depression within it. Length of 

 claspers 0.108 mm.; length of insect 0.8 mm.; length of forewing 

 0.64 mm. 



Adult jemale. — Similar to the male; color of body almost wine 

 colored; costal margin of forewing distinctly wine colored. Length 

 of insect 0.88 mm. In some specimens the dark markings of the 

 wings are more extended than in the figure. Antennae absent from 

 all the specimens. 



Described from pupa cases and males and females in balsam 

 mounts.

Aleurodes plumosa Quaintance, Tech. Ser. 8, Div. Ent., U. S. Dept. Agr., 1900, 

 p. 33. 



This species was described from Florida by the senior author and 

 was inadvertently included in Tetraleurodes by the present writers in 

 Classification of the Aleyrodidae.^ The species is very abundant on 

 cranberries, and many collections from these plants were received 

 from the late Dr. C. W. Hooker, taken at Cranmoor, Wisconsin, in 

 1910. In these collections a large percentage of the pupa cases
