OU 
surinamensis and Carabidee, were found here and there occasionally, 
as also numerous gnats of no known importance, economically or other- 
wise. Outside of the Lepidoptera the only insect commonly seen was 
a chrysopa fly (Chrysopa oculata), a well-known beneficial species. 
The temperature at the time of collecting was about 65° on the streets, 
but the official reported temperature was 60°. 
The list which follows of the species captured, and the percentage 
of their occurrence, both on the date of capture and an estimate of their 
occurrence during the week ending September 23, may be found of 
interest, not only as showing the value of lights in attracting injurious 
forms in autumn, but also for comparison with the list of insects cap- 
tured in a cotton field near Victoria, Tex., October 1, 1897, which was 
published in Bulletin No. 18 (n. s., pages 85-88). Fully half of the spe- 
cies listed are Southern, 7. ¢., forms more frequently found in the 
South than in the Northern States. Anyone who has paid any atten- 
tion to the species of insects attracted to lights in spring and summer 
can not have failed to have been struck with the fact that beneficial 
forms are frequently so abundant as to show in many cases that the 
lights are of practically no value whatever in reducing the numbers 
of destructive insects. Although the noxious forms outnumber the 
others, it must always be remembered that each individual of a preda- 
ceous or parasitic species during a lifetime is capable of destroying 
many individuals of the injurious species. 
The following is the list of captures:

THE ANGOUMOIS GRAIN MOTH IN PENNSYLVANIA. 
It might be remembered by some of our correspondents that we 
made mention of the fact that the Angoumois grain moth (Sztotroga 
cerealella Ol.) is known to occur in the field as far north as Philadel- 
phia, Pa. From accounts which have reached us this fall (1900), it is
