Pseudopomala brachyptera was also collected. The tiger beetles seen were 

 Cicindela hirticollis, purpurea, repanda, marginata, punctulata, sexguttata and 

 tranquebarica; other beetles included Sphccridium scarabceoides, Helluomorpha 

 bicolor, Nematodes penetrans ; butterflies and Polistes were rather scarce, but 

 twenty-seven species of trees were listed. 



Dr. J. Bequaert exhibited about 150 species of Hymenoptera and 50 

 species of Diptera collected on Gardiner's Island during his stay with Mr. 

 Davis from August 17 :o August 23 of last year. Mr. Davis's collecting of 

 191 1 included several additional forms. A specimen of Zethus spinipes Say 

 was taken by Mr. Davis on a previous visit to the Island. Other interesting 

 species were among the Hymenoptera : Methoca stygia Say, Philanthus politus 

 Say, Psen chalcifrons Packard, Crabro provancheri Fox, Trypoxylon politum 

 Say, T. tridentatum Packard, Nysson plagiatus Cresson ; Epeolus lectoides 

 Robertson, E.vernonia Cockerell, Bombus separatus Cresson, B.pennsylvanicus 

 De Geer, B. impatiens, Cresson, B. vagans Smith ; Vespa maculata Fabricius, 

 V. communis de Saussure. Among the Diptera: Spogostylum simson Fabricius, 

 5". paper Loew, Anthrax tegminipennis Say, A. lateralis Say, Exoprosopa fasci- 

 pennis Say; Tabanus nigrovittatus Macquart, Chrysops flavidus Wiedemann, 

 C. vittatus Wiedemann, C. callidus Osten Sacken. 



Meeting of April 16. 



A regular meeting of the New York Entomological Society was held at 

 8:00 P.M., in the American Museum of Natural History, April 15, 1919, Mr. 

 Harry G. Barber in the chair, with 15 members and four visitors present. 



Lt. W. J. Chamberlin, under the title " Collecting in the Blue Mountains 

 of Oregon," gave an account of his work in 19 14 in four different regions in 

 Oregon, especially referring to forest insects, Buprestidse, Cerambycidae and 

 Scolytidse. First eight days were spent in the Florence region in Siuslaw Nat. 

 Forest on the Pacific coast to determine the extent of damage done by the 

 fire of 1866, which as far as insects were concerned, was found not to exceed 

 15 per cent, over ordinary mill loss, being chiefly done by Cerambycidae 

 working in the sapwood. Little incidental collecting could be done on account 

 of heavy rain, but one new Scolytid was found. The rainfall averages 80 

 inches in this region, which is very rough country, broken by many ranges of 

 the Coast Mountains, but of only 500 feet elevation and mild temperature, 

 snow being almost unknown. Douglas fir is the typical tree, though Western 

 Hemlock is quite common on the lower slopes and heavy underbrush is 

 characteristic. 



Next six weeks were spent in the Sumpter region, in the Blue Mountains 

 of eastern Oregon, in the Whitman Nat. Forest. The altitudes range from 

 4,500 to 7,000 feet, rainfall is only 25 inches, but 6 feet of snow in winter and 

 hard frost as late as June to indicate the greater severity of the climate. 

 There is a large variety of trees with Lodgepole Pine predominant and insects 

 are abundant, doing little damage to healthy trees, because there is plenty of 

 dead timber, due to wind, etc., in which they work.
