seemed to have dropped onto the hot sands and perished. Among 

 them that year were a great number of Dicerca tenebrosa, for I 

 secured over two hundred perfect specimens that afternoon. The 

 conditions seemed to be particularly favorable for Coccinelidae, 

 of which I secured a good series of the following : 



Anisosticta strigata, Harmonia picta, 

 Hippodamia $-signata, ij.-guttata, 



convergent, iz-maculata, 



13-punctata, Mysia pullata, 



parenthesis, Anatis i$-punctata, 



Coccinella trifasciata, Chilocorus bivulnerus, 



y-notata, Exochomus tripustulatus, 



transversoguttata, Hyperaspis lateral's, 

 monticola, undiilata, 



tricuspis, Epilachna borcalis. 



Two years in succession, 1891 and 1892, I intended to take 

 full advantage of the usual opportunity, but the warm waves 

 failed to materialize, or else came too late to meet the conditions, 

 and the insects appeared in a slow and unsatisfactory (by com- 

 parison) manner. Even when the warm waves came at the 

 proper time one had to be on hand to receive the full benefit for, 

 by the second day after the warm spell, nearly every insect had 

 either died and dried up or had sought more congenial quarters 

 than that furnished by the driftwood and dry sand. 



Any collector visiting Duluth during late May or first half of 

 June will find the beach along Minnesota Point well worth an 

 investigation, and he may be fortunate enough to strike condi- 

 tions above described.

Some Notes on May and June Collecting around Chicago, III. 



By W. E. LONGLEY. 



Lepidoptera collecting has been generally good so far this year. 

 May and June have been warm with very little rain. Papilio 

 ajax made its appearance in considerable numbers in June in 

 some localities though but few good specimens were taken by 

 any one. I did not take a single good specimen. In former 

 years ajax has been seldom taken here. P. philenor, troilus and 

 tnrnus usually rare, have been occasionally taken; philenor more
