My two specimens of OdontcEiis Jilicornis Say, a male and a female, 

 were taken nearly twenty years ago in a small tract of woods, in 

 northern Illinois, under a decaying log, and I think in late November. 



My only specimen of Tyloderma variegaium (Horn) was taken in 

 early spring, April, I believe, in an ant hill, located in grass land. It 

 was in hibernation, doubtless, as T. foveolatum Say, breeds in the stems 

 of the Evening Primrose, CEnothera biennis, and T. fragarice, in the 

 crown of the Strawberry. My T. variegaium is from Illinois and col- 

 lected many years ago. 



Lina scripia Fab., has increased in some places and become quite 

 destructive to young willow and poplar trees, being especially trouble- 

 some in nurseries, where such trees are being grown. It has been found 

 to be a matter of considerable difficulty to manage these insects, espec- 

 ially the adults, with insecticides, and hand picking was found expen- 

 sive. The present year has witnessed a very material decrease in num- 

 bers of not only adults but in a marked degree among the larvae. The 

 cause of this was pointed out to me by an observing nurseryman, who 

 was not an entomologist, and who stated that there were several other 

 bugs that were destroying the young. On examination, I found these 

 several so called bugs to be the several stages of development of the 

 Spined Soldier Bug, Podisiis spinosiis Dallas. I have since noticed the 

 very young larvre of the bug, stationed about an egg cluster of the beetle 

 and destroying the young as fast as they hatched, and also attacking 

 much larger larvae while these were feeding on the leaves. This year, 

 the trouble by the beetle has been so slight as to obviate the necessity of 

 using preventive and remedial measures against them. 



Not unfrequently we have statements to the effect that insect larvce 

 can be killed by shaking them from the plants, in excessively hot 

 weather, especially if the plants are growing in sand. As showing the 

 possibilities in this direction, though I have never had much faith in it, 

 I will say that during the terribly hot weather which occurred in this 

 country about the first of August, while walking along the pavement, I 

 saw an adult Phytono7nus punctatiis Fab., attempt to pass over a portion 

 of the pavement composed of thick glass for the purpose of lighting the 

 room beneath. The beetle had hardly touched the glass before it began 

 to exhibit signs of distress, and ere it had passed over an inch of the 

 glassy space it turned frantically about, but before it could escape from 

 its torture it rolled over and died. The temperature at the time was 

 above ioo° Fah., on the sunny side of the walls of the buildings, as in- 

 dicated by thermometers.
