Brief notice of tlie unusual history of Blissus leucopterus in 1882, due to 
long-continued cool and rainy weather. Sundry experiments reported, 
including dissections of Lasius flavw and Agonoderus comma taken among 
chinch bugs. First mention of a supposed bacterial parasite of the chinch 
hug. Dilute kerosene emulsion found to he fatal to chinch hugs.

with suggestion of remedies.

1. Suggestion that white fungus on dead chinch hugs in Kansas may he 
identical with Entomophthora or Empusa which destroyed chinch hugs 
near Jacksonville, Ill. 2. Note of successful artificial cultures of Bac¬ 
terium parasite of chinch hug, Micrococcus insectorum. 3. Recognition of 
the subject as of some promise, and one warranting careful investigation. 
4. Reports development of only one brood of chinch hugs in Northern 
Illinois in 1882 which, in connection with their destruction by parasites 
or some unknown cause, makes unlikely any disastrous outbreak in that 
region in 1883.
