ep BULLETIN NO. 1, DIVISION OF ENTOMOLOGY. 
August 31, gives to-day, September 7, the following result: All the 
very young scales killed; nearly all scales one-third grown killed ; 
scales half grown, 34 killed, 11 alive; full-grown and gravid 2 scales: 
mother insect and all eggs dead and dried up, 22; mother insect ap- 
parently alive, but larvie and portion of the eggs at end of scale dried 
up, 15; mother insect and all the eggs uninjured, 10. Of the ¢ scales, 
the greater part were empty at the time of the application; there were, 
however, some with living ¢ pupie; of these most appear to be killed ; 
6 living pupwe were found. The plant, which was most thoroughly 
treated, has lost all the older, devitalized leaves (not a bad thing), and 
shows some signs of injary from the application, but may be benefited 
intheend. It has not started any young growth. When treated it 
was dying of scale attacks. 
September 8.—Visited Harp’s grove. Many trees (bearing, and eleven 
or twelve years old) infested with M. gloverii or M. citricola, or both. 
A tree near the house was dying from scale insect; over half of it had 
been cut away in former years, being entirely covered with long scale. 
It was washed in May last (1881) with Benham’s mixture (ingredients 
supposed to be soft soap, whale-oil soap, potash, lye, and probably sulph. 
of iron, &e.), and is now entirely free from scale and bearing for the 
first time in several years. About 8 gallons of the wash applied with 
an ordinary syringe with rose sprinkler. ‘The tree is a seedling sweet 
orange, and was in bloom when the application was made. The tree 
was very thoroughly treated, and was intended to be a test by the in- 
ventor of the wash. Several other trees, mostly infested with M. cit- 
ricola, were Shown me, washed during the early part of August; same 
mixture, sprinkled several gallons to each tree. On these the effect 
has not been so complete, and the scalesare spreadingagain. The mix- 
ture used upon some trees has turned black and spviled, and has had 
no effect whatever. 
Harp’s grove is and has been noted for its bright oranges; the fruit 
of many trees is entirely free from rust, and on these a most careful 
seareh failed to reveal any ‘“rust-mites” on fruit or leaves. A few 
trees in one part of the grove show rusty fruit and mites on leaves and 
fruit. An oceasional orange is found, the rind of which has been eaten 
and perforated by a lepidopterous larva. This in every case worked 
under aleaf which happened to be closely applied to the surface of the 
fruit, and had been fasteneddown by a web. The larva does not appear 
to differ from that of one of the common leaf folders, and is probably 
a Tortricid. The fruit perforated is invariably lost and drops from the 
tree, owing to the attacks of a fly maggot, which enters and feeds upon 
the juice, rotting the fruit. The Nitidulid beetle, Carpophilus ferrugi- 
neus Murray, also attacks such injured oranges, and its larva also occurs 
in the rotting fruit. 
Mr. Harp’s cotton is being ragged by Aletia. The caterpillars are one- 
half to two thirds grown, with younger and older worms mixed. Isaw
