We are not in a position to offer a systematic classification of 

 the Cossidae,* but believe this paper will be of value as a contri- 

 bution thereto ; indeed this will be something, for authorities do 

 not agree as to their treatment. Pro tempore, we adopt Rebel's 

 (Iris xi.) subdivision of this group into Cossinae and Zeuzerinae, 

 of which there appear to be some forty-five species in Australia 

 — eleven Cossinae, thirty-four Zeuzerinae, to which may be 

 added three species of Phragmataecinae. The group is entirely 

 without representatives in New Zealand. 



We regret exceedingly having been unable to procure ova 

 for examination, but it may be of interest to note that the ovum 

 of Cossus cossus (Europe) is ornamented with " crystalline " 

 sculpture on the eggshell ; nor have we examined newly-hatched 

 larvae, doubtless the first instar will furnish details of value, 

 but these groups do not difi'er widely in any stage as to larval 

 structure, according to Dyerf only in the absence in the first 

 instar of the tubercle above the base of the abdominal feet. The 

 material with which we are familiar consists of larvae older than 

 the first instar, and some pupae. 



* We understand Rothschild is engaged on a revision of the group.
