INSECT CONDI TICHS IN GUATEMALA DURING MARCH AND APPJL, 1931 
Mars ton Bates 
12 Calle Orients No. 1, Guatemala. 
The coffee cricket seems to be following the sarre cycle this year 
as last: no neF oviposition scars have been noted since March. An aclu.lt 
cricket found on the coffee was determined as P a r o e c an thu s guatemala.e 
Saussure by Prof. T. H. Hubbell, and as the juveniles that emerged 
from the egg scars would seem to belong to this or some allied genus, 
it seems likely that this species is causing the trouble; but nothing 
definite can be. determined 1 without further study. 
Saissetia hemi sph a e rica ' Targ. is a common and .widely distributed 
coffee scale in Guatemala, but one that rarely occurs in injurious 
numbers. A severe infestation "-as found in April, however, on coffee 
in the Barberena regions. Severe infestations of mealy bugs are also 
reported from various places, especially higher altitudes, in the 
cloud zone. 
Specimens of Diaohania. ni tidal is Stoll . Tore pent in for determina- 
tion and advice from the south coast, vdth the comment that they ■'"ere 
doing considerable damage to a cucumber planting. The insect has also 
been quite common in cucumber fruits offered for sale in the city 
market during the past t v *o months. 
Larvae of Elateridae yore again found doing considerable damage 
to potatoes. An undetermined flea beetle ^as also found to be causing 
considerable injury to this plant in the Tecpan region. 
Cutworms ^erc reported as doing considerable damage to alfalfa in 
certain regions. Adults r-ere bred but have not as yet been determined. 
The pine forests at higher elevations in Guatemala are continuing 
to die out, apparently because of insect attack, so that in some regions 
whole mountainsides -ill not have a living tree left. The insects that 
have been collected from these dying pines include: Ins cribricollis , Eichh. , 
Dondroc tonus mcxicanus / and D. adjunctus . Blandf, 
Hook.
