Head dirty gray. Antennie a little darker and slightly pi- 

 lose ; length of joints : I. 0.10 mm.; 11,0.10 mm.; Ill, 0.18 

 mm.; IV, 0.28 mm.; V, 0.20 mm.; VI, 0.05 mm.; total 

 length, 0.90 mm., not quite half the length of the body. Sen- 

 soria are absent except at the base of the unguis, where one is 

 located. Eyes abnormal, small and black, with three ocelli in- 

 stead of the common cornea. Ocelli not located in the normal 

 position but cephalad and near the bases of the antenme. They 

 are large, translucent and situated in dark patches, each sepa- 

 rate from the other. The beak is four-jointed, slightly hirsute 

 and dark, except the first joint, which is lighter in color. 

 Length, 3.44 mm., extending about one-half its length beyond 

 the abdomen. 



Thoracic lobes not distinctly divided, nor separate from the 

 head. All grayish in color. The legs are darker than the ab- 

 domen, slightly pilose and stout. Honey-tubes and style en- 

 tirely obsolete. Length of bod}'-, 2.08 mm. 



This form was taken April 25, in an ants' nest which was in 

 an old walnut stump in a small copse of timber. It is pulveru- 

 lent and similar in action to other underground species. 



From all appearances this form had hibernated in the ants' 

 nest all winter. Only three were found. I expected to collect 

 more during the summer, but none were to be found in the 

 nest or on the trees in proximity to it. 



Subfamily CHERMAPHIN^. 



Antennae three- or five-jointed. Eyes nearly always large 

 and prominent. Beak short, or never very long. Prothorax 

 large, sometimes equally developed to the thorax. Cephalic 

 wing with three simple oblique veins (plate III, fig. 22) ; 

 caudal mayor may not have an oblique vein. Legs short; 

 tarsi with two claW'S. Honey-tubes absent. 



This tribe is in many respects similar to the Coccidse. 



Genus Phylloxera Fonsc. 



Antennae three-jointed ; the first and second short and nearly 

 equal ; the third the longest, imbricated ; it has two sensoria, 

 one circular one near the base and one more elongate near the 

 distal end. Sometimes total length is equal to one-third the 

 length of the body. Eyes small and almost rudimentary in the
