OF WASHINGTON. 117 



from the stomach of a nighthawk {CJiordeilcs firginianus) 

 collected on Amelia Island, Florida. It is true that night- 

 hawks, whippoorwills, and other birds of this family have very 

 large mouths adapted for capturing insects of large size. 

 Nevertheless, it seems remarkable that they can swallow entire 

 such large and powerful dragonflies as the two species first 

 mentioned. 



— Mr. Webb stated that he had spent the summer in investi- 

 gations, for the Bureau of Entomology, of insects injurious to 

 the forests of southern Arizona and New Mexico. In the 

 White Mountains of New Mexico he found a large tract of 

 dead Engelmann spruce killed several years ago by the Engel- 

 mann spruce barkbeetle, Dendroctonus engehnanni Hopk. No 

 living examples of the insect were to be found, however, it 

 having swept the forest and disappeared as D. frontalis did in 

 Virginia and West Virginia several years ago. 



Mr. Webb also exhibited a specimen of the work of a twig- 

 girdler on alligator juniper found near Paradise, Ariz., and 

 stated that he expected to breed out the adult of the larva 

 which had done the girdling. He called attention to the fact 

 that this is the first known instance of a twig-girdler having 

 been found on juniper in North America, although Professor 

 Froggatt had reported finding a girdler upon the juniper of 

 Australia. 



A specimen of the work of Phlceosinus sp., found on Arizona 

 cypress near Paradise, Ariz., was exhibited, as also a col- 

 lection of photographs illustrating various phases of Mr. 

 Webb's summer work. 



— The following two papers were presented for publication :
