312 E. ERNEST GREEN, REMARKS ON COCCIDAE. 
The occurrence, on an Island with a new fauna, of a Coccid 
previously recorded only from California, is of peculiar interest, 
An examination of the oceanic charts shows that the equatorial 
current, accompanied by the North East Trade Wind, sweeps 
directly from the shores of Mexico and California to the Malay 
Archipelago. The survival of a minute soft-bodied insect during 
the vicissitudes of a marine voyage half way round the world 
might seem almost inconceivable, but is not actually impossible. 
Many Coccidae are able to withstand long periods of starvation. 
Protected, as are the ‘Mealy Bugs’, by a waterproof covering 
of mealy secretion, and possibly concealed within a creviceof 
some log or rough-coated fruit, they might eventually be cast 
up and obtain a footing upon the littoral vegetation of some 
country many thousands of miles distant. If this has happened 
in the present case, it is probable that the species first 
established itself upon some of the more eastern islands of 
the archipelago. Another and more easy method of distribution 
might have occurred through the direet importation of living 
plants from California to the famous Botanical Gardens in 
Java, whence its accidental conveyance to Krakatau would be 
comparatively simple. The fact that the species has not yet 
been observed on any of the intervening islands is of little 
or no importance, as our knowledge of the insect fauna 
(especially of the more obscure orders) of this region is still 
quite rudimentary. 
3. Lecanium (Saissetia) hemis phaericum, Targ. 
(Coll. Jacobson, Nos. 1428 and 1552) Semarang, Java. On 
Loranthus sp. and Flacourtia Ramontchi, L'Hérit. Attended, in 
both cases, by the ant Oecophylla smaragdina, F. This is another 
cosmopolitan species. 
4. Lecanium discrepans, Green. 
On Sesbania aegyptiaca, Pers. Attended by Oecophylla smarag- 
dina, F. (Coll. Jacobson, Nos. 1120, 1124 and 1251) Semarang, 
Java. Previously recorded from Ceylon only.
