-west Louisiana in 1905. have not made their appearance in such de- 

 structive numbers since that time. 



Insects Injurious to Shade and Ornamental Trees 

 In this class we have found nothing of especial importance, the 

 pests mentioned in the above-mentioned article being present in about 

 normal quantity. The Gulf Fritillary. Dione vaniUce Linn., is almost 

 always found upon the passion-vine. Passaflora incarnata, with which 

 a number of the galleries in various parts of South Louisiana are 

 covered, and the dropping of the spiny red and black "worms" has 

 "almost caused" untold cases of feminine hysterics! 



The larv£e of Homaledra sahaJclIa Cham., (kindly identified by Mr. 

 Busck), have caused considerable injuiy to palms in Calcasieu Parish^ 

 in the southwestern part of the state, during the past summer. They 

 fold the leaves and feed inside the inclosure thus made, skeletonizing 

 the leaves. 



Insects Attacking Men and Live Stock 



Nothing of interest has transpired among these insects during the 

 past two seasons. We have had no severe outbreaks of the buffalo 

 gnat, Simidium pecuarum Kiley, reported to us. This insect at times 

 appears in destructive numbers, and the loss of a large amount of 

 stock always results. The horn-fly, Hcematobia serrata R.-D., has 

 been very abundant in parts of the state, and has caused considerable 

 annoyance to farmers in the infested districts. The various species 

 of Tabanus and Chrysops have been noticed in about their usual 

 numbers. 



The chicken mite, Dennanijsus gallinke Eedi, has been several times 

 sent into the office with complaints of injuiy and annoyance. 



NOTES ON CALOSOMA FRIGIDUM KIRBY, A NATIVE 

 BENEFICIAL INSECT^ 



By A. F. Burgess, Melrose HioMamU. Mass. 



During the past three seasons extensive investigations have been 

 carried on at the Gypsy ]\Ioth Parasite Laboratory at Melrose High- 

 lands. ]\rass., in order to secure more accurate knowledge of the 

 biology of the European parasitic and predaceous insects that are 

 being introduced for the purpose of securing the natural control of 

 the Gypsy and Brown-Tail Cloths. Considerable data has also been 

 obtained concerning native species which destroy some of our common
