Four chrysomelid leaf "beetles are' generally present in "bean plantings. One 
of these, Pi atretic a specie sa Cram., is also common on a great variety of other 
crons. 
The cane "borer Diatraeo saccharali s Fab. constitutes one of the principal 
cano insects in the State of Minas Geraes. Dr. C. Moreira has reported that the 
larvae of this insect, which generally confine their attack to younger canes, 
appeared in some fields in older stocks (1931). 
Among the insects attacking sugarcane, Tomn spi s litorata Lep. & Serv. ap- 
peared on the increase this year but caused smaller losses than in 1920 and 1924, 
- Len it threatened cane growers in many regions. This pest is known to occur in 
the States of Hinas Geraes, Sao Paulo, and Parana and there are varieties occur- 
ring in Motto Grosso and Hio Grande do Sul. (C. Moreira. ) Several species of 
family Cercopidae attack sugarcane in Brazil. Kahenarva in die at a Dist., the spe- 
cies most commonly found, is widely distributed through Kinas Geraes. Although 
it has never "been considered of much importance, there is reason to believe that 
it is likely to cause serious losses in certain varieties of cane. 
Two scarabaeids, Li gyrus humilis Burm. and L. fossator Bum. appeared or 
were first noticed in a large sugarcane plantation at Rio Branco, Minas Geraes. 
The grubs of these beetles destroyed several acres of a new planting during 
1930. In 1931 the infestation, confined chiefly to a low, poorly drained area, 
was very much reduced after soil treatments. 
Tomatoes were heavily attacked during May to July by Leucine des clegan talis 
Guen., whose larvae tunnel their way into the young fruits, completing their de- 
velopment at harvest time. Losses as high as 80 per cent wore not uncommon. This 
"broca" is the most important insect enemy of tomatoes 
• o. 
A sv.'eetpotato curculionid, Eusceoes batatae TTaterhouse, common in all Brazil, 
caused higher losses in imported potatoes in the College plots this year. The 
weevils continue their destruction long after the potatoes are placed in storage. 
The pickle vprm ( Pi aphonia ni tidal is Stoll) caused 75 per cent loss in a 
small planting of cucumbers at Vicosa. Adults of this species and of D. hyalina- 
ta L. were very common at electric lights during the period fro^ November until 
June. 
Leucine des cl ego: -talis Guen., which caused such losses in tomato* was also 
found attacking eggplant on several occasions. 
The grape phylloxera ( Peritymbia vastatrix Plonchon) is still limited to a 
small zone in Bio Grande do Sul. (C. Moreira.) 
A lepidopterous larva, Bra s soli s astyra Godt., was present in sufficient 
numbers this year to almost defoliate many palm trees at the College. 
T»""o new scale insects collected at Vicosa in October and November have been 
described as Sol ssetia minensi s Hcm-oel and Vic so 1 econi urn ^1 onum Hemoel, both new 
to science. 
On th r ■ -ental Thu.ja occidentalis on the College campus ~erc observed for 
time scale insects deTermincd by A. Hemoel as Djasois visci Scir. He 
reports that this is the first time that the s-'ecios has been knov.n to occur in 
Brazil.
