The cotton leaf -miner, Nepticula gossypii Forbes and Leonard, Many- 
plants showed evidences of considerable mining of the leaves earlier in 
the life of the crop at Penuelas. 
The cotton stainer Dysdercus negiectus Uhler was reported abundant in 
an old cotton field long past picking on June 25 at Carolina. D. andre^e L., 
by far the most common of the two here, was almost entirely absent* 
Specimens were submitted to check the determinations, Mr. Flores now 
believes that the stainershe reported on in April (I.P.S.Bulletin 11 (4)&36, 
June, 1931) were almost all if not entirely negiectus instead of andre^. 
One specimen of Oncopeltus aulicus Fab. was brought in but I judge it was 
probably not feeding on the cotton bolls. (Ismael Flores Lugo, Agricultural 
Agent. 
Dysdercus andreae L. has not been troublesome so far during the month 
on the North Coast and the blister mite Eriophyes gossypii Banks is scarce. 
-(E. F. Rorke) 
The black scale, Saisset ia nigra Neitner, was present in the greatest 
abundance in Penuelas that I have yet seen in the island, many plants 
having the stems and twigs entirely encrusted with the scales. 
The cotton leaf blister mite, Eriophyes gossypii Banks, was observed 
badly infesting many old plants in a field from which the drop had already 
been picked on June 2 at Penuelas. 
The infestation of the "pollilo," Cryptotermcs brevis Walk., was 
reported in one of the government buildings in San Juan. Upon investigation 
it was found that many valuable records had become infested, some of then 
so badly as to have been practically destroyed.
