Observations on the Oviposition of Oecanthus quad- 

 ripunctatjs Beutenmuller. 



By J. P. JENSEN, 

 Entomological Department, Cornell University. 



(Plate II) 



Oecanthus quadripunctatus has been considered by some 

 writers a light form of Oecanthus fasciatns or nigricornis, 

 but my observations on the habits of the two insects would 

 seem to indicate a specific difference. The former deposits 

 its eggs in a peculiar manner in raspberry and blackberry canes, 

 if these are convenient, while Oecanthus fasciatns, also present, 

 I have not seen oviposit similarly. 



I first found a female of Oecanthus quadripunctatus ovi- 

 positing in the stem of a wild aster, late in the afternoon at 

 Eagle Bend, Minnesota. The eggs were placed singly in the 

 stem. In the same locality, during the month of September, 

 I also found the females plentiful in a large patch of common 

 thistles, and as they were on the leaves and stems of the thist- 

 les all day for several weeks and no other weeds were near, 

 it seems probable that they also lay their eggs in the stems of 

 these plants. 



On October 5th, at 5 :3O P. M., while searching for Oecan- 

 thids in a raspberry patch near Cornell University, I came upon 

 a female in the act of ovipositing in a cane. She was placing 

 her eggs in an irregular row up the stem and had already made
