live insects had probabl)' been clashed during a rain-storm of the 

 night before and there left to perish helplessly." 



"August 11. — May-flies and caddice-flies somewhat scarce." 



"September 21. — On the bill-board near the bridge, the caddice- 

 flies were congregated in numbers, and the noise produced by 

 contact of their bodies as they alighted on the paper was like a 

 continual tapping sound, which first drew my attention." 



"October 5 and 6. — On bridge each night between eight and nine 

 o'clock. Nights cool, with full moon shining. Insects were more 

 numerous on these moonlight nights than on dark night pre- 

 ceding. Watching carefully for new species of caddice-fly." 



{Remarks to above. — This new species was first recognized in 

 my material by Prof. V. L. Kellogg, but it was named by Nathan 

 Banks, from specimens sent to him, as Hydropsyche kansensis.) 



A favorite location for beetles and moths was found at the 

 light in South park. Here the light was frequently lowered. 

 Wherever game is to be found, there the hunter seeks it. We can- 

 not blame some people who, not knowing about an entomologist's 

 business, may express wonder at his strange actions, particularly if 

 on a street corner at night. But when they begin to question your 

 mental condition, you will probably guard your conduct. A certain 

 party asked a friend: "What is the matter with Mr. T.; is he 

 crazy?" The friend, rather astonished at the question, which 

 seemed to be asked in earnest, replied that Mr. T. had always acted 

 all right ; at least he had never done anything strange as far as 

 known; therefore, could not account for such an impression. 

 "Well," the party explained, "he acted very queer the other night. 

 He stood near the lamp-post on the opposite corner of the street 

 and waved and jerked his arms in the air, jumped about on the 

 sidewalk, and ran around the lamp-post several times." 



The use of traps in which to catch insects at night, by the al- 

 lurement of light, is an important method receiving but partial at- 

 tention. The advantage of a trap is such that, after once rigged 

 up for the night, it "works while you sleep." But next day the 

 work will fall on the collector, who ha6 the catch to pin up. Some 

 traps are so constructed that insects may be allured directly into 

 one, in attempts to reach the light placed inside ; another form is 

 arranged to catch insects which fall into it after reaching the light 

 that is openly exposed above it. In any case, however, the insects 

 meet death in a poison jar fixed to receive them, and which is usu- 

 ally charged with cyanide of potassium, although other agents for 

 suffocation, as chloroform, for instance, can be applied.
