bases of iii. and iv. are forked and bear two setae and there are alsa 



additional secondary set?e rising from the general skin surface that are in 



no way associated with the primary tubercles. I have preserved but 



unmounted larvse of this species in their ist instar, and as with P. trifolii 



I shall be glad to forward them to Dr. Dyar if he desires to examine 

 them. 



There does not appear to be any issue between us with regard to 



Dimorpha, but I should like to enquire as to what is inferred by the 

 remark " but it does not suggest the Laclmeidce nor Liparidce proper.'' 

 Are we to understand this as denoting a relationship between these two 

 groups other than the general one in that both belong to the same order?

 a narrow band between the antennae and the eyes, head above the eyes, 

 and the temples, white; antennae black, nine-jointed, third slightly arcuate, 

 thicker and longer than the fourth, which is in turn longer than the fifth, 

 and so on to the last. Thorax shining black, laterally in front of wings 

 white ; wings hyaline, nervures brown, whitish at base of wing ; first 

 transverse cubitus transparent, without colour, second submarginal cell
