 yellowish white basallv ; first tarsal segment short, second much 



produced, third half the

 shorter and about as long 

 as the first, fifth very short ; 

 claws bidentate. The middle 

 leg is practically the same 

 as the anterior except for 

 the well defined basal band 

 on the tibia ; posterior leg

Male. This sex closely resembles the other except in size. The 

 antennal segments are possibly more cylindric 

 and not quite so much dilated as those of the 

 female, while the palpi appear to differ in hav- 

 ing the basal segment considerably larger than 

 the apical, both bearing irregularly located, 

 stout, chitinous setae. Basal clasp segment 

 stout, slightly curved exteriorly, strongly exca- 

 vated interiorly ; terminal clasp segment strongly 

 arcuate, terminating in a rather blunt, dark, 

 recurved spine, other structures indeterminate 

 in the preparation. 



Pupa. Yellowish brown with brownish wing 

 pads extending nearly to the middle of the 

 abdomen, the leg cases reaching to the ex- 

 tremity and the antennae extending almost to 

 the basal abdominal segments. This pupa is 

 stout and easily recognized because of the defi- 

 nite markings, there being a series of light Fig 

 lateral spots on each of the brownish abdominal 

 segments. The brown tarsi have definite 

 yellowish white bands. 



Larva. The full grown larva is about 1.25 mm long, pale yel 



lowish with the segmen
