Summer Work on Insects 



Professor M. M. Ellis, of the University of Colorado, will conduct 

 a course on the Natural History of Insects (elementary collegiate 

 zoology being a prerequisite thereto) and will direct special or research 

 work on insects at the Summer Session of the Biological Station of the 

 University of Michigan, at Douglas Lake, Michigan, from July 2 to 

 August 24, 1917. 



Calopteryx dimldiata apicalis (Odon.). 



In recently looking over some Odonata I found a damaged male of 

 this species with the following data: "Dragonfly taken from canoe on 

 Rancocas Creek three-quarters mile below New Lisbon, N[ew] 

 [Jersey] Aug. 17, 191 1, by S. N. Rhoads. About five males like this 

 and as many females with less black were seen. Nowhere else seen. 

 Always over water in shady places. A rare species there." Brown's 

 Mills (also on the Rancocas) and Raccoon Creek are the only other 

 records for the Delaware valley in the 1910 list of the Insects of New 

 Jersey, so the recording of the present specimen is justifiable. The 

 specimen has gone to Dr. R. Heber Howe, Jr., of Concord, Massachu- 

 setts. — Philip P. Calvert.
