The white peach scale, Aulacasois nenta?on a Targ. , was moderately 
abundant on napaya trees or. a farm near Ponce on August 5. Several 
"pesquin" trees ( Albizzie, mollis ) at the Hio Piedras Station, used as 
shade trees in an experimental coffee planting were rroderately infested 
with this scale. 
Adults of Diaureucs sTJengleri L. were present in fair numbers (but 
fewer than on the same trees last June) on several trees of a Picus 
(probably P. laevigata ) near Santa, Isabel on August 20-22. Thirty-five 
egg rra.sscs were collected during several hours of careful search in an 
effort to obtain tfrichogrammid C r-^> parasites for introduction into 
Barbados. The percentage of parasitisir corld not be determined at the 
tire. 
A leaf tyer, Dichoreris pineratus Wlsm. , was found to be rather badly 
infesting a small experimental catch of alfalfa at Malcza in the munici- 
pality of Aguadilla on August 4. This is in a rather isolated section 
containing many hat palms, and little farming has been done there; this 
occurrence of the insect in injurious number's at sore considerable distance 
from the only other nearest alfalfa grown at the Isabela Substation again 
raises the cuestion as to what the natural leguminous food, plant of the 
insect really is. 
An undetermined scale was brought in en August 8 by Dr. T. Breggcr, 
^ho stated that several "bucare enano" trees ( Srythrina berteroana ) were 
somewhat infested in the experimental coffee plots at the station. On 
the same date Dr. Bri gger found an voi determined scale which was rather 
badly infesting several "ucsou.in" trees ( Albizzia roll i s ) used as shade 
trees in an experimental coffee planting at the Pio piedras Station. 
The Hawaiian beet webworm, Hymenia fascial is Cram., wr.s much less 
abundant than during July at El Morro in S^-n Juan. The scarcity of the 
moths and larvae was undoubtedly duo to the destruction of most of the 
patches of the weed "arraza contodo" ( Gonuhrona d.isucrsa ) on which the 
insect has been feeding there.
