140 THE CANADIAN ENTOMOLOGIST. 



NOTES. 

 While in search of beetles last June, one of my companions drew 

 attention to a colony of large black ants in a decayed pine stump. We 

 noticed a great many minute yellow creatures running unmolested among 

 the ants. Examination proved them to be Staphylinids, which I thought 

 were of the genus Atemeles, and afterwards they were identified as such. 

 We have been unable to learn the species as yet. The beetle is about an 

 eighth of an inch long, and the abdomen, which is always held erect, 

 bears a peculiar depression on the upper side in such a way as to leave a 

 distinct ledge around the edge. Shortly afterwards we found one of the 

 same species in a spider's web. On July 15th I was surprised to see 

 Cicada tibicen with its proboscis buried in a squash bug, A?iasa trisiis. 

 This was my first intimation that the Cicada might feed on animal 

 matter. — Eric Montizambert, Port Hope. 



We regret to record the death, at the age of seventy-six, of Dr. H. 

 Guard Knaggs, F. L. S., an English Entomologist of note, which took 

 place on the 16th of January. He was the author of many contributions 

 to entomological literature, among the most widely known of which is his 

 "Lepidopterist's Guide," a third edition having been published a few years 

 ago. This is a popular work, containing instructions for collecting, rearing 

 and preserving Butterflies and Moths for the use especially of the young 

 collector. 



The Lake Laboratory maintained by the Ohio State University 

 announces the usual programme for the coming summer, including courses 

 in General Zoology and Botany, Entomology, Ornithology, Experimental 

 Zoology, Comparative Anatomy, Ecology, Embryology, Invertebrate 

 Morphology and Ichthyology ; also opportunities for research work and 

 accommodations for investigators as in previous years. The opportunities 

 offered are especially good for Entomology and for fresh-water conditions, 

 and special attention is given to the aquatic life of the locality. Oppor- 

 tunities for research work in these directions are very favourable. 

 Independent investigators are given the use of tables free of charge, but 

 are expected to furnish their own microscopes and other apparatus. The 

 locality is an excellent one for summer work, the laboratory being situated 

 on the point separating Sandusky Bay from Lake Erie, with its frontage on 

 a fine beach. For circulars or information address the Director, Professor 

 Herbert Osborn, Ohio State University, Columbus, Ohio. 



Mailed April 6th, 1908.
