THE CANADIAN ENTOMOLOGIST. 379 



species, Longicorns and Buprestids, Sirex albicornis and abdominalis and 

 Xeris caudatus, Braconid parasites of wood-boring Coleoptera, and 

 especially Odotiiatilacus edit us, of which I took 26 specimens. Along 

 moist spots on the trail and shore were large numbers of bees of many 

 kinds and swarms of butterflies. 



The botanical results of the expedition were more thorough and 

 important than the zoological, and will prove invaluable to the student of 

 the fauna as well as the flora. Over 20,000 sheets were brought home, and 

 an additional iS,ooo the previous season. These represent very fully the 

 flora of the region. In addition to this, the party was equipped with regis- 

 tering thermometers, sling psychrometers, aneroid barometers, radiation 

 thermometers, evaporometers, photographic outfits, and other apparatus for 

 studying the ecological and bionomical conditions that prevail, and which 

 will, I hope, result in facts of no less importance to the zoologist than to 

 the botanist. The leader of our expedition was Dr. Charles H. Shaw, 

 Professor of Botany in the Medico-Chirurgical College of Philadelphia, an 

 enthusiastic naturalist and a charming companion, to whom the author 

 wishes to express his thanks for many courtesies and facilities provided 

 for his work. Among other members of the party were Prof Heinrich 

 Peterson, of Ursinus College ; two students from the Medico-Chirurgical 

 College ; Mr. Merkel Jacobs, of the University of Pennsylvania, and part 

 of the time Miss Alberta Cory, of the Kansas City High School ; Miss 

 Ellen Runner, of Lake Forest College ; Miss Mary T. Jobe, of the 

 Cortland (New York) State Normal School, and others. Some of these 

 were interested in botany, several of them devoting their entire attention 

 to the collection of plants. I was the only member of the party interested 

 in zoology. 



II. — New Aculeate Hymenoptera. 



I hope to be able to publish from time to time lists, notes and 

 descriptions, which will be preliminary to a knowledge of the insects of 

 the region. As a beginning, I here publish the descriptions of three 

 Hymenoptera, one a Bethylid of the genus Gonatopus, remarkable for its 

 curious and ungainly appearance and for its rarity. Another is of the 

 family Pemphredonid?e of the genus Blepharipus, which has heretofore 

 been known in America from three female specimens representing two 

 species. There is one European species.
