Note on Hepialus argentiomaculatus. 



13y D. S. KELLICt)TT. 



At the Ann Arbor meeting of this Club 1 described the larva and 

 pupa of an unknown species of moth, supposed to be one of the Cossidce. 

 I provisionally called it Cossus alni. I'he examples were obtained in 

 Oswego Count\-, N. Y., from the roots and stems of Alnus incana. I 

 showed that the larva probably requned three years to complete its 

 growth and that the habits were substaniially those of the better known 

 species of its group. 



Efforts to obtain the imago were fruitless until this present summer. 

 A pupa sent to me from Hastings Center, Oswego County, N. Y., June 

 ist, gave a female imago June 2nd and it proved io\)Q Hepialus argentio- 

 maculatus. 



I have little to add to what I have already said in the Club concern- 

 ing its history. I have found the wood-peckers most successful rivals in 

 collecting the mature larvi\?. In the Fall before the final changes are to 

 occur tliey bore up into the stems and the birds then seek them and suc- 

 cessfuU)' re^nove them from burrows that are deep in the wood. As the 

 larva does not then open the way to the surface the bird must locate it 

 by sounding. The larvoe occur in abundance in the locality where 

 found. 1 have sought for it at Buffalo and elsewhere without finding it. 



Mr. Schwarz stated that he had collected the species on ihe shore of 

 Lake Superior, near Marquette, July 29th of the present year. 



Mr. Smith stated that he had met with it in various places and he 

 believed it to be probably quite generally distributed, and breeding in 

 Oak, Willow and Poplar. 



Mr. Kellicott remarked that he had taken Prionoxystus querciperda 

 from the lunbs of Red Oak. 



Herbert Osborn presented a note on the occurrence o'i Cicada riniosa. 

 Say, in Iowa. 



" During the present summer 1 have received from a student, Mr. 

 F. A. Sirrine, living in Tama Co. . Iowa, a lew specimens of Cicada 

 rimosa, Sav. As this is the first time I have met with specimens collect- 

 ed in the State and as I had supposed its distribution did not cover any 

 portion of the State it is perhaps worth while to put its occuirance on 

 rec(Md Its distribution must be local or else its occurance quite rare, 

 otherwise it would probably have been noticed by some of the collectors 

 in the manv years during which insects have been collected in low^a. 

 The specimens received were collected in a grove in the North Eastern 

 part of Tama Co. and said to be quite abundant there. Another student,
