THE CANADIAN ENTOMOLOGIST 257 



Mr. Marlatt, who had assisted Mr. Riley in his work on this insect, 

 described more particularly the structure of these perforations, illustrating 

 by blackboard sketches. They are really distinct tubes of a gutta-percha- 

 like appearance and consistency and differing entirely in texture from the 

 remainder of the structure. Inwardly they were closed by a layer of silk 

 so that they really did not perforate the entire cocoon. 



In response to a question from Mr. Wallace he stated that he did not 

 think any commercial use could be made of the cocoon. 



Mr. Schwarz commented on the present state of our knowledge in the 

 Phengodini We do not know what is a species in Fhengodes, and pro- 

 bably too many names exist. Of Zarhipis we have four named species, 

 which must be reduced to two, integi-ipennis and riificoUis, the latter in- 

 cluding riversii and piciventris as colour varieties. Of several eastern 

 species oi Phengodes it is difficult to get specimens of the male, and we do 

 not even know the male of the species occurring in Maryland and the 

 District of Columbia. Prof Riley has the only collection containing the 

 larviform females of several eastern species of P/iengodes ; but only one 

 of these, laticollis, has been connected with the males. 



Mr. Mann asked whether not more than one species existed in 

 Massachusetts. He has described in Psyche three forms of larvae or 

 females that he collected in that State. 



Mr. Schwarz replied that he had never seen a male Phengodes from 

 Massachusetts ; but there was probably only a single species. The 

 three different forms of luminous larv?e described by Mr. Mann may be 

 satisfactorily accounted for by supposing one to be the larviform female 

 imago, the second the larviform pupa of the female, and the third ths 

 larva of the male. 



On motion the Club adjourned to meet again under the rules at the 

 next meeting of the A. A. A. S.
