The cottor. lacebug, Corythucha goj^rjeil Fab. , Fas very destructive 
at the Rio piedras Station on pole lima..s, ir. creasing in a bur.dar.c'e so that 
by the end of the month many le'aves Fere broFninh and dry, the insect s 
being present in all stages in great numbers. 
Hie Scarabee, guscgoes batatag Uaterh. , -as found lightly infesting 
one sweetpotato tuber in the public market at Puerta de Tierra, San Juan, 
(H. Faxon and E.G. Oakley-.) 
A small blackish flea beetle Fas very common in all the sFeetnotato 
patches examined and apparently doing scire damage. This looks like 
ChaetocneTa a.nricaria Suf friar:, and I fouIcI say definitely it is that 
species, for it is our sFcetootato flea beetle in Porto Rico, except 
that Long and Mutchlor do not record it from Antigua — only from Porto 
Rico and Cube,, and in the Supplement they add Jamaica and Haiti. 
An adult of the bug Snartocera batatas Fab. Fas found attacking 
sFeetpotatoes in the oatio of the Tain building at the station at Rio 
Piedras on August 18 and later in the month several adults Fere observed 
on the walk outside the same building. 
A leaf miner, Arrorryza. ip_ojreae Frost, Fas "ore sent throughout the 
month as usual in ^oder^tc numbers in several sFeetnotato matches 
observed. 
The cotton lacebug, Corythucha gossyoii Fab., Fas found tOFards the 
end of the rronth in snail nuTbers on the okra, at the Rio Piedras Station. 
The okra adjoins the "oole lirras on which the insects Fere breeding very 
abundantly. Only adults could be found on the okra., but these Fere feed- 
ing to a. noticeable extent, causing the characteristic yelloFish stipnled 
areas on the leaves. 
A leaf beetle, Diabrotica gramir.ea Paly, did considerable damage to 
leaves and blossoms on the okra. natch at the Rio Piedras Station. 
A whitefly, undoubtedly Al eurotrachelus trachoides Back, was found 
on August 17 to be badly infesting a house pep-oer plant in Santurce. 
The red- banded thrips, Heliothrios rubrocinctus Giard, was observed 
doing considerable to moderate damage to the foliage of about 1,000 
nursery mango trees at the station at Rio Piedras. Thorough soraying o.t 
once almost eliminated the insects, but by the end of the month they were 
again beginning to get a good foothold. 
The papaya, fruit fly, Toxo try nana curvi cauda Gerst., Fas found to be 
infesting the fruits of a number of nanara plants on a. farm near Ponce on 
August 5. One fruit, small and green and about 2-1/3 inches long, con- 
tained 20 larvae, and another, somewhat more mature and about 5 or 6 inches 
long, contained 24 larvae; in both fruits the maggots were nearly to* 
fully grovn. The owner stated that during May and June nearly all of the 
fruits on his trees was infested, many so badly that they had to be thrown 
away.
