our observations show this injury to blackberry and especially 

 raspberry canes is due not to Oecanthus niveus but to Oecan- 

 thus quadripunctatus. Dr. C. V. Riley in his 5th Missouri 

 Report, p. 119, after describing the injury and illustrating it 

 by the figures that have had such general use in reports and 

 text books ever since says : "These are the eggs of the Snowy 

 Tree Cricket (Oecanthus niveus Harr.), an insect briefly de- 

 scribed in my First Report." In the Supplement to his Ninth 

 Report p. 60, he says : "Oecanthus niveus. This species is com- 

 mon in all parts of the country, and I have proved by breeding 

 that the eggs are those described and figured as such in the 

 5th Report." 



In the early summer, I caught a few individuals of Oecan- 

 thus niveus on raspberry and blackberry bushes in the eve- 

 ning, but most of them were on peach, plum and cherry trees 

 and were already at that time busy laying their eggs singly 

 in the stems and branches of these trees. In October no O. 

 niveus specimens were to be found on the raspberry bushes 

 while 0. quadripunctatus was busy ovipositing in the canes. 

 Each afternoon I would find one or two of them at work, 

 while O. niveus was still ovipositing in the stems of the trees 

 and they outnumbered O. quadripunctatus at least 100 to i. 

 It seems, therefore, that O. niveus is innocent of the injury 

 resulting from the long rows of egg-punctures in berry canes, 

 and that we must consider O. quadripunctatus the only cul- 

 prit at least until O. fasciatus or nigricornis has been found 

 guilty of the same offense.

The present paper is based upon a collection of Tlivsanop- 

 tera made in Southern Illinois during the past few months by 

 Mr. Lindley M. Smith, Assistant to the State Entomologist of 

 Illinois. As the collection is large and fairly exhaustive, rep- 

 resenting many hours of careful collecting, I take especial
