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 : 



Anisoslida strigata, Hartnonia pida, 

 Hippodamia ^-signata, " 14-guiiaia, 



" cojivergens, " 12-maculaia, 



" ij-pu7ictata, Mysia pullata,

Coccinella tri/asciata, Chilocorus bivulnerus, 



' ' g-notata, Exochomus tripustulatus , 



" transversoguitata, Hy per aspis lateralis, 

 " monticola, " undulata, 



" tricuspis, Epilachna borealis.

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

By W. E. LONGLEY. 



Lepidoptera collecting has been generally good so far this year. 

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

 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 

 turnus usually rare, have been occasionally taken; philenor more
