in Indo-Malaya than in Africa. Haplothrips is almost 
world-wide in its range, and Cryptothrips also, and, whilst 
Liothrips is also represented in many parts of the globe, the 
species from the Seychelles depart from the usual type and 
come closest to the species described from Ceylon by 
Schmutz under the name Ischyrothrips niger, and which he 
classed with other species obviously belonging to other 
genera. 
Rodrigues Island. 
In the many vicissitudes and delays experienced in working 
out Dr. Scott’s material a further small collection came to 
hand from one of the Mascarene Islands, Rodrigues, and I 
have had an opportunity of including this material in an 
Addendum (p. 286). 
The collection was made in the island of Rodrigues 
between August and November (inclusive) of 1918 by 
Messrs. H. P. Thomasset and H. J. Snell, and was sub- 
mitted to me through the kindness of Dr. Scott. 
Rodrigues, about 11 miles by 5, is the smallest of the 
Mascarene Islands and very isolated, being about 350 miles 
E. by N. of Mauritius, and, of course, a very long way from 
the Seychelles, from which it also differs entirely in forma- 
tion, being volcanic, whereas the Seychelles Islands are 
purely granitic. Rodrigues is mountainous, rising to eleva- 
tions of 1100 to 1300 feet. The grand tropical forests 
which once covered the island have been almost entirely 
destroyed by fire, goats, pigs, and direct human action. 
Though there are still 297 indigenous Phanerogams and 
175 indigenous Cryptogams (probably only about half the 
original native flora), and though in ravines many fine old 
native trees have escaped destruction, yet the island is com- 
paratively dry, and there aro no areas of dense, moist, 
native forest such as those which still remain in the 
Seychelles (see H. J. Snell and W. H. T. Tams, “The 
Natural History of the Island of Rodrigues,” Proc. Camb. 
Phil. Soc. xix. pp. 283-292, 1920). 
The following is a list of species recorded and described 
from Rodrigues Island herein ;—
