Jrom the Seychelles Islands and Rodrigues. 261 
The first is apparently the same as the Mahé species, the 
second and third have Seychelles affinities, whilst the fourth 
very strongly confirms and emphasizes the Indo-Malayan 
affinities of the fauna. 
Before proceeding with the technical account, I will 
briefly outline certain observations of general interest :— 
Viviparity. 
In mounting the dried specimens of Idolothripide 
Mr. H. Britten drew my attention te the fact that two 
minute larval young (obviously of the first instar) floated 
from a female of Dicaiothrips seychellensis, m. (Mahé, 
no. 65). This is the first instance of the kind with which 
I have met. 
I have already published Mr. Urich’s communication on 
an allied species (D. brevicornis, Bagn.), in which he notes 
having observed females deposit eggs on the leaves of a dead 
coconut-palm and sit on them *. 
Teratology. 
Examples of thrips with one or other of the antenne 
malformed are by no means rare, and such malformation is 
illustrated in an example of Dicaiothrips hystrix, m. (Sil- 
houette, no. 25) ; it usually takes the form of a fusion of 
segments, generally the more distal ones. A rarer terato- 
logical condition is shown in the ¢ type-specimen of the 
same species (D. hystriz), where the left outer postero- 
marginal pronotal bristle is duplicated, the second being of 
about equal size and situated close to the normal seta. 
An Entomophagous Fungus. 
In the upper part of the abdomen of an example of 
D. hystrix, m. (Silhouette, no. 25), 1 detected several 
hundreds of a minute organism indiscriminately disposed, 
and each of a fusiform shape comprising three segments. 
I was at first inclined to think that this was a protozoon. 
They proved to be fungus spores, however, and at the
