is light brown ; length of joints : I, 0.10 mm. ; IT, 0.07 mm. ; 

 III, 0.45 mm. ; IV, 0.21 mm. ; V, 0.21 mm. ; VI, 0.12 mm. ; 

 VII, 0.23 ram.; total length, 1.59 mm., being about equal to 

 the body in length. Sensoria circular and few, usual distal one 

 present on the fifth, one equal to this in size on the distal end 

 of tlie sixth, and a smaller one at the basal part of the seventh. 

 Eyes black, ocular tubercles and ocelli absent. Beak dark and 

 short, 0.18 mm. long, extending to the mesocoxis. 



Prothorax not plainly set apart from the head. Thorax has 

 no distinct lobes, but has two patches of dark coloration on the 

 dorsal part, as shown in the illustration. Legs slightly hirsute ; 

 also there are from a few to eight flabelliP on each one ; femora

 Femora especially well developed, the cephalic pair the largest.

 or six setaceous hairs, which are on prominent tubercles. 

 Length, 0.09 mm., being equal to the honey-tubes in length. 

 Total length of the body, 1.50 mm. 



This form was taken May 4, from grass sw^eepings ; conse- 

 quently its host-plant and habits are not exactly known. 

 Since only one was taken, and the coloration of it not well 

 noted, the description may not be exact.
