sacchariphagus, which is the most serious cane pest of Mauritius. The 
insect enemies of Citrus fruits are considered at some length. With the 
scale-insects we are already familiar through the reports of Mr. Koe- 
bele's trips to Australia, as well as the reports of Messrs. Tryon and 
French. Outside of scale-insects, however, oranges are damaged in 
Queensland by the larva of Papilio erectheus, which works in the same 
manner as the congeneric " orange dog" of Florida. Queensland pos- 
sesses a new type of orange insect, however, in the shape of several 
species of Noctuid moths, of which Ophider'es fullonica is the most 
prominent, and which ruin the fruit by inserting their haustella and 
sucking the juices in just the same way that the Cotton Moth damages 
figs in our Southern States. 
COFFEE INSECTS IN HAWAII. 
In the Planters' Monthly for December, 1893, published at Honolulu, 
Mr. William G. Wait gives an interesting summary, upon pages 559- 
562, of the insects which he has found affecting the Coffee-tree in the 
Hawaiian Islands. The insects considered are all scale-insects and 
comprise Dactylopius destructor, Pulvinaria camellicola, and an unde 
termined species of Lecanium. The author has found Coccinella abdo- 
minalis and a species of Scymnus breeding upon the Dactylopius and 
Coccophagus haivaiiensis How. MSS., and Dilophogaster californica 
parasitizing the other two species. A smut fungus ( Capnodium lanosum) 
follows the scale-insects and does more damage to the plant. The fun- 
gus is eaten by a species of Psocus, colonies of which live in gauze tents 
on the under surface of the leaves. 
ABUNDANCE OF WASPS IN SOUTH BRITAIN. 
In Tlie Entomologist for January, 1894, Mr. W. Harcourt Bath records 
that in every part of south Britain visited by him, wasps have swarmed 
in countless numbers during the past season, in some districts doing 
great damage to the fruit crops. He attributes the abundance of the 
swarms to the dry weather of the preceding spring. 
AN UNNECESSARY CASE OF PROTECTIVE RESEMBLANCE. 
Mr. John T. Carrington, in Science Gossip for March, 1894, in an 
interesting little article upon roosting butterflies, brings out a number 
of interesting cases in which butterflies, in choosing their " roosting 
places " select locations in which they will be protected by their resem- 
blance to their surroundings or to the object upon which they roost. 
Curiously enough, he republishes from Insect Life the figure of 
Anosia plexippus published upon page 206 of volume V, in which the 
butterflies are roosting in numbers upon a dead twig. Here, says Mr. 
Carrington, resemblance to a twig covered with dead leaves is plainly 
aimed at, and this resemblance is protective. To a person giving a
