DIFFERENTIAL GRASSHOPPER ( Helanoplms dil fere nti alls Thos.) 
Texas A. I. Faois (September 24): Me lanoplus dif f erentialis Thos. is 
very destructive to pecans along Colorado River, Pecan Bayou, and 
Conchos. They fed extensively on immature pecan nuts during July 
and August and defoliated trees during September. Defoliation 
during last season caused shrinkage of kernels and rendered crops 
from infested trees unmarketable. 
LITTLE HICKORY APHID ( Monellia carvella Fitch) 
Texas A. I. Fabis (September 24): Very injurious on pecan trees at 
Brov/nwood which were sprayed with arsenicals during the summer - 
rare on unsp rayed trees. 
PECAN LEAF CASE-BEAKER ( Ac rob as is nebulella Riley) 
Texas A. I. Faois (Septemoer 24); Larvae were found abundant on native 
pecan timoer along the headwaters of the South Llano River. This 
insect does net occur north of that section. 
PECAN NUT CASE-BEARER ( Acrobasis hebescei la Huist) 
Texas A. I- Faois (September 24): Infestation by the second generation 
was very light locally, out rrore abundant in San Saba and south- 
ward . 
CITRUS AND SUETROPIC/L FRUITS 
FLORIDA. RED SCALE ( Chrys omphalus f i cus Asian.) 
Louisiana H. K. Plank and assistants: The freeze of last January at New 
Orleans, when the temperature went to about 18° to 19°F. in 
nearly all parts of the city, practically eradicated this scale 
en plants growing out of doors; to date we have oetn able to 
find only a lew scales. On host plants growing indoors it con- 
tinues to be a pest of considerable importance. This insect is 
attacking C in. r. ag c m urr. c eg. p 1; c re. , Citrus spp . , L igust rum spp., and 
numerous nursery and greenhouse plants. 
BICTYOSPERMU?! SCALE ( Ch rrs omo h alu s d i ct vp s p e rm i Mo rs; . ) 
Louisiana H. K. Plank and assistants (September 25): ,,r ing largely to the 
freeze of last January, when the temperature went to about 18 c to 
19°F. in nearly all parts of the City of New Orleans, this scale 
is very scarce except in a very few apparently sheltered locations, 
Some parasites have been noted again this year, out their work at 
present is inconsiderable. This insect is attacking Cinnamomum 
c amphora and Ficus rep ens .
