Many data have already been gathered with reference to the life 
histories of Philippine mosquitoes, and a series of publications looking 
toward the eventual monographing of forms found here is part of my 
program for the near future. 
When more is known in this regard, we can the more successfully 
plan and execute preventive campaigns against these insiduous foes of 
mankind. 
USEFUL INSECTS. 
SILKWORMS., 
Of the work that has been done on useful insects, principal mention 
might be made of experiments looking to the introduction of silkworms 
into the Islands. 
As far back as 1593 attempts were made by one of the early Spanish 
priests, Padre Antonio Sedeiio, to introduce the silkworm into the Philip- 
pines, he having brought the mulberry and the “seed” here from China. 
Again, in 1780, Padre Manuel Galiana made a second endeavor but with- 
out success, save that plants from some of the original mulberry trees are 
still to be found in Manila and the Provinces of Tarlac and Batangas. 
In spite of the fact that silk growers claim a temperature of more than 
25° C. as injurious to the silkworms, our experiments both in the labora- 
tory and in the field have proven that an excellent grade of silk can be 
obtained. 
Our chief care will be as to the best method or keeping the eggs from 
the time of laying to hatching, but we hope to solve this by the use of a 
mild degree of cold in cold storage, facilities for which are now to be had 
in the chief towns of the Archipielago. 
BEES. 
Up to the present little attention has been given to bees in these 
Islands. There are at least three wild species which are found in consid- 
erable abundance throughout the Archipelago: Megapis dorsata Fabr., 
M. zonata Smith, and Apis indica Fabr., with A. nigrocincta Smith and 
A. unicolor Latr., which by some are considered mere varieties. 
Of these, it is doubtful if Megapis dorsata Fabr., will ever submit to 
domestication. Apis indica Fabr., has already been kept successfully in 
hives and does fairly well, considering the fact that no scientific cultural 
methods have been followed. 
There is no reason why American or Caucasian bees would do otherwise 
than well in the Philippines, although two attempts at importation on 
the part of a private individual have proven failures, owing to improper 
care of queens and brood in transit. 
A rather inauspicious augury for the raising of bees here is the fact 
that the bee moth (Galleria mellonella Linn.) is very abundant and
