The "bean lacebug ( Corythuch a gossyoii Pat. ) was present in abundance 
September 8 at the Station. The insect was observed in moderate numbers 
on a number of castor bean plants in different parts of the Island, Septem- 
ber 26 - 28. 
A mealybug, Pseudococcus sp. , was found September 8 generally though 
lightly distributed throughout a fair-sized natch of "Dole limas at the Sta- 
tion on both leaves and stems. 
Moths of the melon worm. ( Piamhania hyalinata L. ) were fairly common 
at light during three nights' collecting, September 25 - 27, at Puerto Real, 
Vieques Island. 
The small black squash bug ( pycnoderes incurvus Pist.) was fairly com- 
mon at light during three nights' collecting, September 25- 27, at Puerto Real, 
'Vieques Island. 
The Hawaiian beet webworm. ( Hymenia fascialis Cramer) continued to be 
abundant throughout the month on the weed G-onohraena disnersa at HI Morro 
in San Juan. 
Grasshoppers did considerable injury to several large tomato plants 
grown for experimental purposes in the greenhouse at the Rio Piedras Station, 
daring the latter part of the -no nth. The injury was by young green nymphs. 
Adults have not as yet been obtained. 
Adults, of the sweetpotato weevil ( Cylas formicarius Pah.) were not un- 
common during three nights' collecting at light at Puerto Real, Vieques Is- 
land, September 25 - 27. Arturo Riolla.no, the local Agricultural Agent, 
stated that he had observed the insect as generally distributed and very in- 
jurious since he had been on the Island from September, 1930. 
The corn ear worm ( Heliothis obsoleta Fab.) infested practically every 
ear of sweet corn at Isabela during the month (G-.IT.T7.). 
was received 
A leaf beetle, Metachrpma antennalis ".l/'eise/f rom the Aguirre Sugar Com- 
pany «sas» .'" " under date of September 4 for determination. The beetles 
were said to be present in enormous numbers and doing great damage to rose 
bushes. Out of over 1,000 good-sized rose bushes over 400 had been killed, 
the beetles first eating the flowers, next the leaves, and finally gnawing 
off the bark of the woody parts. The beetles first appeared in the spring 
of 1929 and were present the following year and this year from April into 
September. It was stated that when disturbed the beetles drop readily. This 
species was orginally described from Porto Rico in 1885 by J. "Jeise and has 
apparently not been reported outside of the Island. Here it has been re- 
corded as rather badly attacking cotton at Queb radii las in June, 1922, and 
was found between leaves and in spider nests on various plants on the beach 
at Arecibo in May, 1923.
