either equal to or a little longer than the tibia. Marginal spines (fig. IG, e) minute, 

 slender and hair-like ; stigmatic clefts scarcely indicated ; their spines (fig. 16, e)

 not fused, about one-fourth the length of the body. Anal lobes similar to those of the 

 adult.

Larva. Normal in shape. Antennae (fig. 16,/) slender, about one and a half times 

 as long again as those of the adult and second stage female ; terminal segment in- 

 crassate and with the apical hair nearly half the length of the antenna ; 4th, 5th and 

 6th with a slender spine. Marginal and stigmatic spines similar to those in the 

 succeeding stage. Rostral filaments nearly three times the length of the body. 

 Apical setae on the anal lobes about the same length as the body.

 those near the margin much larger. Marginal spines (fig. 17, b) of two kinds : 

 (1) long and rather stout, dilated and divided on both sides ; (2) similar spines, but only 

 about half the length of the long ones. Stigmatic clefts practically obsolete ; spines
