The scarabaeid "beetle Dyscinetus barbatus Fab. was abundant during 
early May this year and last "ear, at Isabela, (G.N. Wolcott. ) 
The first adult Lachno sterna vandinei 'Smyth was observed this year 
on March 10, the second on April 10, and they were abundant during late 
April. Last - r ear the first adult was observed on April 19 and they were 
abundant last year in April, at Isabela. (G.N. Wolcott. ) 
The first adult Lachno sterna citri Smyth was observed this year on 
April 15 and they were abundant on April 17; last .year the first adult was 
observed on April 17 and they were abundant on the 18th and 19th, at 
Isabela. (G.N. Wolcott.) 
The period of greatest abundance of the large weevil (vaquita) 
Diaprepes abbreviatus L. as adult is also during the latter part of April, 
following a period of several months when rarely can an individual be found. 
During the rest of the year the beetles are present in reasonable numbers, 
with minor variations, but during the first quarter: of the year adults are 
very scarce. Their appearance in the latter part of April coincides with 
the new flush of growth on citrus and other trees, caused by spring rains, 
which have been normal this 5 r ear. Even for this irrigation district, how- 
ever, one can hardly consider the almost 10 inches of rainfall that have 
fallen in the last 48 hours as being quite normal. 
A pentatomid bug, F ecel ia minor Voll. (H. G. Barber det. ), was found 
in small numbers (adults) on the fruit in an orange grove near Ponce and
