with four segments, segment 1 incomplete, segment 2 usually complete 

 tho reduced to a mere line on cephalic part, segment 3 narrowed on cepha- 

 lic part, segment 4 short, conical, or peg-like; larvapods setiferous, setae 

 4-6 in number as viewed from lateral aspect; anal larvapods rather large; 

 glandubae sessile; cuticle microscopically spinulate; suranal and subanal 

 lobes with numerous setae; larvae free leaf -feeders. 



Diphadnus appendlculatus Hartig. — Length, 13 mm.; width of head, 

 1.35 mm.; body green, venter glossy white; tenth abdominal tergum not 

 marked; head greenish white with blackish brown streak along epicranial 

 stem, except near the occiput, and continuing to the dorsal two-thirds of 

 front, vertex dorsad of each ocellara not quite reaching the epicranial 

 suture; surface of head with minute brownish spots; following parts 

 brown: mandibles at apices, antennae, cervical sclerites, coxae at proximal 

 third, tarsal claws, and spiracles; setae minute, with conspicuous calices, 

 blackish; glandubae smaller at distal end than the calyx of seta; larvapods 

 on cephalic and lateral aspects with 4-6 setae and with a single ventral 

 glanduba; annulation, 1, (6, 2), (3, 5), 4; subspiracular lobe with 5-6 

 setae and without glandubae; surpedal lobe with about 4 setae and one 

 subsessile glanduba; on gooseberry; Y-158, -159, M-128. 



Pristiphora Latreille

 usually slightly enlarged at abdominal segments 5-6, tapering at each 

 end; thorax not swollen; tenth abdominal tergum without the paired 

 caudal protuberances; third abdominal tergum with six annulets, annulets 

 2 and 4 microscopically setiferous, setae sometimes obsolete; annulet 1 

 always longest and annulet 3 and 4 always shortest; spiracles usually 

 winged, caudal wing usually much smaller than cephalic; head marked 

 usually with a blackish or brownish streak along epicranial stem, surface 

 with minute brown spots; labrum with distinct mesal emargination and

 four distinct segments, segment 1 always minute, incomplete on caudal 

 side, segment 2 complete, but usually narrower on cephalic side, segment 3 

 uniform in length, segment 4 short, conical; larvapods usually glabrous 

 and with a single ventral glanduba, if setiferous, setae microscopic, 2-4 

 in number as viewed from side; anal larvapods rather conspicuous, glandu- 

 bae sessile or stalked; cuticle microscopically spinulate, suranal and 

 subanal lobes with numerous setae; tenth abdominal tergum as seen 

 from side notched dorsad of suranal lobe; free leaf -feeders.
