and burrows made by larger insects, and feeds indiscriminately upon every 

 part of the plant, while its little white larvae bury themselves deep in the 

 tough and spongy interior, gradually reducing it to powder. Under the 

 combined attacks of the adult Cis and its larva the fungus becomes a thin, 

 dry shell, tattered and riddled with holes. Or its hold on the tree trunk 

 being undermined, it is beaten to the ground by rains, and becoming 

 water-soaked is abandoned to the snails, poduras and scolopenders.

Aradus debilis, in all stages. Predatory (?), breeding in the fungus. 



Two species of lepidopterous larvae, undetermined. Feeding on the 

 fungus. 



Unknown coleopterous larvae of several species. Probably predatory. 



In reply to a question from Mr. Weed, Mr. Hubbard stated that no 

 dipterous larvae were noticed, and Mr. Schwarz stated that the fungus was 

 doubtless too dry for the larvae of this order. 



Replying to a question by Mr. Ashmead, Mr. Hubbard stated that he 

 thought a very similar fungus was to be found upon pine logs in the 

 South. 



Mr. Schwarz hoped that this paper would bring forth other investi- 

 gations of a similar character showing the intimate relations of insects and 

 fungi. 



Mr. Riley then read a paper on " The American Bean Weevil," which 

 will be published hereafter. 



In reply to a question by Mr. Fletcher, Mr. Riley stated that this 

 species could not be definitely stated to be of American origin.
