obsolete during the transition , the males take no iioiirisluneut, 

 and the short life obviates all necessity for food. 



THE FEMALE. 



The growth of the female is very rapid after the appearance of 

 the male. There is no distinguishable metamorphosis and the female 

 does not acquire wings. The dorsal and ventral integument are of the 

 same bright yellow color that has characterized the sex from the be- 

 ginning of the larval form. The divisions of the body become less 

 distinct as the development proceeds until it is only after mounting 

 that the insect can be studied with accurac}'. 



The dorsal integument is smooth, of uniform color throughout 

 and the divisions of the body obscure. The sides are even in outline, 

 witli a slight restriction at the divisions and with short hairs irregu- 

 larly projecting from the body. The small pores are more numerous 

 and larger than in the earlier stages of the insect, and from all part^ 

 of the integument short, slender hairs extend wliich issue from circular 

 projections. 



The body of the female, Figure XXI, is nearly oval and becomes 

 almost round as it fills with eggs. 



The eyes are small and quite round, they arc inserted a short 

 distance back of the antennae and at the margin of the head. They 

 are dark red, and appear black when mounted. 



The antennae are situated on the underside and widely separated. 

 They arc nine jointed, having numerous long flexible hairs on the 

 surface. The color of the antennae is the same as the body and 

 uniform throughout. 



The first joint of the antennae Fig. XVII is large and well 

 se3ured to the body, the seven following become gradually shorter, 

 the last and ninth is as long as the third and terminates in a point. 

 Tlius with the growth of the female an addition of three joints have 

 1»een made. The female, unlike the male, has had no perceptible 

 pupa state neither regular moults, and in the antennae do we find 

 the greatest change of the appendages. 



The beak consists of four long slender setae. 



Tlie thorax increases in size every way. The six legs are present, 

 but the body becomes so distended that it is utterly impossible for 

 the female Avhon in the process of deposition to walk any distance, 

 yet she can, with difficulty, proceed. The legs have not developed 

 with the body and yet have not lost their use. They are quite simi- 

 larly constructed and Fig. XVIII is a representation of one of them. 

 The cox',i is strong, and is both long and stout, with onlv a few hair.'*
