rnine the progress of control resulting from liberations of Crypto- 
Ic.emus and to locate any inf estattions requiring additional atten- 
tion, shoiaed 13,3SS acres to 'ce infested or 23 per cent of the 
total citrus acreage in the county, an increase of only U per cent 
over the preceding year. The inspections shov/ the infestation of 
the coastal citrus areas representing approximately 12,000 acres 
to "be 70 per cent complete v/hile the interior or foothill sections, 
including the San Fernando Valley, representing approximately 
43,000 acres sho-.v only S per cent infested. As a result of the 
spring inspection, infestations throughout the county r.-ere graded 
S2 per cent light, 13 per cent medium, and 5 per cent heavy, 
'jnder normal field conditions it is necessary to liberate on only 
3 small percentage of the light infestations and both medium and 
heavy infestations can be checked -dth liberated Cryptolaemus -rdth 
only nominal injury to the property from the attack of the mealy- 
bug. Unfortunately, field conditions -ere such this season thr.t 
•7hile they permitted the normal development of the m.ealybug, the 
prolonged cool, damp -eather materially delayed the activity of 
the Cryiptolaoraus. In fact, to such an extent that in spite of a 
laboratory production of Cryptolaemus , permitting the complete 
coverr^e of all infested properties reQ.uiring it, during the nor- 
mally optimum period of April, May, and June, more or less injury 
resulted to the present crop. The injury r.-as evidenced in the 
form of small sizes, "s'lAitty" fruit and a drop of rmture valencias 
in the heavier infestations. Black scale ar.d orange tortrix, hov:- 
ever, have been serious contributing factors to these lossos this 
season so that it -jould be difficult to estimate the direct loss 
resulting from the attack of the mealybug. The Crj'ptolaemus have 
made up in part for their spring delay by a late season activity 
"vhich is resulting in satisfactory seasonal control. In fact, in- 
festations are at a minimam at the present time and present liber- 
ations of Cryptolae;Tus are being conf?.ned to those properties 
•-.here necessary control measures for other insect pests in the 
orchards have int erf erred -dth the completion of mealybug control 
from the initial libei-ations. 
JIEXICM FRUIT V'OIU,I ( Anastrepha ludens Loe'.7) 
S. 3. Fracker (September 2J): l^o specimens of this insect have 
yet been gound in the grapefruit crop of 1927-2S. The last one 
discovered -as on June 23 in some late fruit of the previous season.

HISCSLLaIIEOUS fssdzrs 
BLACK BLISTER BEETLE ( Epicc.uta pennsylvanica DeC-.) 
E. 'T. :iendenhall (Septem.ber 16); These blister beetles are fluite 
troublesome in several of the counties in central and southern 
Ohio attacking asters and gladiolus.
