April, '11] gossard: insects of the year 209 



seasons by the same party as causing severe damage to his sugar corn. 

 The clover hay-worm was reported from two parties as destructive 

 to alfalfa in mows. The bumble flower beetle, Euphoria inda, was 

 reported from several localities as unusually injurious to corn in the 

 silk. Euphoria sepulchralis was also received once or twice with a 

 similar accusation against it, or rather was included among the sam- 

 ples of Euphoria inda. The mealy flata, Ormenis pruinosa, and the 

 green flata, Chlorochara conica, were both received in a sending of 

 insects said to be exceedingly destructive to ginseng. The red- 

 humped caterpillar of the apple was more than usually prevalent 

 throughout the state as was also the oblique banded leaf-roller. The 

 raspberry Byturus has been injurious locally, here and there exceed- 

 ingly so, but its distribution in destructive numbers seems to be very 

 restricted. The grape-berry worm has caused comparatively little 

 damage and can scarcely be found in some of the neighborhood where 

 it was so abundant a few years ago. The linden tree louse, Lachnus 

 longistigma, was very abundant in Cleveland for the past two seasons 

 rivaling its record in Washington city for 1889. The maple sesian, S. 

 acerni, has been very injurious to maple trees for two or three seasons. 



The potato scab gnat, Epidapus scabei, was located in a potato 

 patch just in the outskirts of Cleveland. It was quite destructive; 

 so, much so that a request was filed with us for an investigation, and 

 this led to its discovery. No seed had been imported onto the place 

 for several years, from which we were obliged to infer that it was 

 indigenous to the locality. 



In the latter part of August, we received from Shandan, Ohio, the 

 tenebrionid beetle, Platydema riificorne, working in stored corn. They 

 hollow out the grains while on the cob, and seem to possess all the 

 capabilities for damage which characterizes a number of other pests in 

 the same family. So far as we have been able to determine, nothing 

 has been published hitherto regarding the life-history and habits of 

 this beetle. 



President Sanderson: Is there any further business before we 

 adjourn? 



Mr. Washburn: You were kind enough to include me in the men- 

 tion of thanks for the entertainment here. The work at the Agri- 

 cultural College has been done by my assistants, Messrs. Ruggles, 

 Urbahns, and Stafford, and whatever thanks you offer are due in 

 part to them. 



There being no further business the meeting adjourned. 



A. F. Burgess, Secretary.
