The general characteristics of the adult female have bccMi doscriijcd by 

 Kuwana, but there remain certain points of interest. The mouth-parts appear 

 really to be lacking as they are absent in all of numerous preparations examined 

 It is not impossible, however, that further examination would reveal a condition 

 similar to that found in Xylococciis macrocarpce. 



There are four pairs of abdominal spiracles (not noted by Kuwana), these 

 of the type shown in Fig. 18. D. 



Penidtimate sta^e. Oval in form (Fig. 18C). AntenUiC reduced to mere 

 chitinized points. Spiracles arranged as in the adult but of a quite different

form (Fig. 18B). Margins of the body with large, circular pores '(Fig. 18E), these 

 mcst numerous toward the head. Anal opening simple, without an anal tube. 



First stage larva. (Fig. 18A). The description given by Kuwana appears 

 to be accurate except for the statement, "Margins of the body with capitate 

 hairs." These hairs do not appear in my specimens. The larva is so minute 

 that I have been unable to detect the arrangement of the spiracles, or, indeed, 

 whether or not they are present. Each abdominal segment bears at the margin 

 a small object that may be either a pore or a spiracle. 



Material examined. Preparations from the type material.
