Following Ihc samo ordci- as in tlie case of the 

 male, I shall shou : 1" a drawing made from an 

 adult female; -j" a drawing made fioni a female 

 Avhich died dnriiig the last moult; 3" a drawing 

 made from a larva 36 mm. long. In addition 1 have 

 studied the antenna of a larva 28 mm. long. 



idUll jcmalc, 3 müiiths old counting from the 

 last nioult. (iig. 9). — The liliforni antenna is 9 mm. 

 long as eompared with 18 in the male. The three 

 basal joints are mueh the same as in the male; the 

 3r(i is longer than at the time of the last moult and 

 nearlv e(|ual to the jauì. The following joints are 

 at first slighth broader than long, become about 

 equal in length and breadth towards the middle of 

 the antenna and In the apical region are about twice 

 as long as broad. The last joint bears a filiform 

 process, slightly curved. The projections on the 

 surface are less pronounced than in the male and 

 the light-coloured circles smaller and less numerous. 



Female which died during llu' /n.si nioult. 

 (fig. 10). — Vs in the case of the imago the naniber 

 of joints is 53 ; but the antenna is much shorter 

 (5.5 mm. instead of 9); the joints in the neighbour- 

 hood of the base are relatively to their length even 

 wider. We may therefore affirm that in the female 

 as in the male the antenna continues to grow after 

 the last nioult so as nearlv to doid)le its length.
