damage by climbing the full-grown grain stalks and cutting off the 

 heads. Slight injury was done also to newly seeded winter wheat. 

 In the early spring, about the first of May, grasshoppers were sur- 

 prisingly abundant north of Miles City. No specimens were sent 

 us and we cannot state what the species was. 



The Sand Cricket (Stenopelmatus sp.). More inquiries than 

 usual were received regarding the sand cricket or Jerusalem cricket. 

 Several specimens were sent in as curiosities, with requests for 



information. 



THEIPS (THYSANOPTERA) 



A Grain Thrips (Anaphothrips striatus Osb.). There was a 

 considerable loss in oats, with a slighter loss in barley and wheat, 

 due to a sterility of the florets caused by the feeding of this thrips. 

 In several instances, especially where the head had not completely 

 emerged from the boot, live specimens of thrips were secured, which 

 were determined as this species. In several sections oat fields were 

 examined and the loss from this insect was estimated at about 10 

 per cent. 



The Onion Thrips (Thrips tdbaci Lind.). The onions growing 

 on the experiment plots on the college farm were found to present 

 a rather sickly appearance, which was at first attributed to hail 

 injury. Closer examination revealed the fact that the injury was 

 mostly due to the onion thrips. Adults and young were both found 

 in great numbers on the leaves. 



Thrips on Nasturtiums. Nasturtium leaves were sent in for 

 examination which showed typical thrips injury. A few of the 

 thrips were found but they were dead and so dried and broken that 

 it was impossible to make a determination of the species. 



THE TRUE BUGS, PLANT LICE, ETC. (HEMIPTERA) 

 The Bedbug (Cimex leetularius Linn.). Requests for informa- 

 tion about bedbug control were fully as numerous if not more so 

 than in previous years. It is hoped to publish a leaflet containing an 

 account of the habits and control methods of the bedbug for distri- 

 bution before next season. 



The Chinch Bug (Blissus leucopterus Say). This insect was 

 reported from three different localities, but as no specimens were 

 sent in for identification the reports have not been verified. The 

 chinch bug occurs, so far as we know, only in a few counties in
