RECENT PUBLICATIONS OF INTEREST TO FLORIDA 
ENTOMOLOGISTS 
“Fumigation of Citrus Plants with Hydrocyanic Acid: Con- 
ditions Influencing Injury” by R. S. Woglum. U.S. D. A. Bul. 
907. 
“The Black Fly of Citrus and Other Subtropical Plants” Dietz 
and Zetek. U.S. D. A. Bul. 885. 
“Cotton Boll Weevil Control by the Use of Poison,” B. R. 
Coad. U.S, D. A; Bul. 375. 
“Results of Experiments with Substances Against Chicken 
Lice and the Dog Flea,” W. S. Abbott. U.S. D. A. Bul. 888. 
The author recommends good, fresh pyrethrum powder for both 
pests and sodium fluorid and mercurial ointment for chicken lice. 
“The Beet Leaf-Beetle” (Monoxia puncticollis Say), Chitten- 
den and Marsh. U.S. D. A. Bul. 892. Florida is included in 
the range of this beetle but it does little damage here. 
“The Pear Borer” (Aegeria pyri Harris), F. E. Brooks. U.S. 
D. A. Bul. 887. Evidently the author did not consult Grossbeck’s 
List of the Lepidoptera of Florida in outlining the insect’s dis- 
tribution as he omits Florida from the list. 
Farmers’ Bulletin 1148 on ‘“‘Cowpea Culture and Varieties” 
has a section on the “Insect Enemies of the Cowpea,” “prepared 
with the advice and cooperation of E. A. Back.” This deals 
mostly with the seed weevils. The most troublesome of all the 
insect enemies of cowpeas in our section and the limiting factor 
in their cultivation for seed production, the Pod Weevil (Chalco- 
dermus aeneus) is not even mentioned. 
Farmers’ Bul. 1102, ‘“‘The Crow in its Relation to Agricul- 
ture.”’ The author’s conclusion is: “The influence of the race 
as a whole for good and harm appears to be about equal.” This 
has reference to the “common crow” of most of the U. S. The 
most common crow in at least the central part of Florida is not 
this species but the Fish Crow. This does not seem to trouble 
sprouting corn or chickens to any extent. 
Farmers’ Bul. 1122 is on “Citrus Fruit Growing in the Gulf 
States” by E. D. Vosbury. It contains the spray schedule. 
“Orthoptera of N. E. America” by W. S. Blatchley (Nature 
Publishing Co., Indianapolis, Ind.) is the last word on this group 
of insects. It is a large and complete book of 784 pages, with 
very full descriptions and notes on habits, distribution, food and 
life history of all our species. It contains about 250 illustrations. 
It is invaluable to students of this order of insects.
