Hymenopterous genus Scleroderma. 121 
The anomaly is carried still further in the Ceylonese 
S. vigilans, of which I have only seen two female speci- 
mens, one of which had fully-developed wings and ocelli 
(Pl. V., fig. 8), whilst the other was wingless, but 
possessed ocelli (Pl. V., fig. 4). But the anomalous 
characters of the genus are not confined to the females, 
since Sir §. 8. Saunders captured a wingless male, 
provided with slender antenne and with three large 
ocelli, but entirely destitute. of wings. (Plate V., fig. 7). 
The curious objects observed by Sir 8. 8. Saunders, 
extruding from the bodies of the insects on undergoing 
their transformations, and which at first sight appeared 
like some Entozoon or parasitic larva, were submitted by 
me to Mr. W. H. Jackson, M.A., F.L.S., one of the 
demonstrators in the physiological and comparative 
anatomical department of the Oxford Museum, who has 
made the Entozoa an especial object of study, and he 
has favoured me with the following memorandum, in 
conjunction with his fellow demonstrator, Mr. Algernon 
P. Thomas, B.A. :— 
“The worm-like bodies submitted to us by Professor 
Westwood possess the following characters :—They are 
brownish in colour, translucent, and fairly smooth in the 
dried condition. Careful examination in a bright lght 
showed traces of segmentation. In one of the specimens 
there are contained bubbles of air or some gas. We 
soaked one specimen in glycerine and water, and then 
examined it by reflected and by transmitted light, and 
by both combined. It showed no trace of internal 
organisation. There were few granules present, and 
it appeared to consist of irregular masses agglomerated 
together. We believe, consequently, that these worm-like 
bodies are not organisms at all, but more probably are 
excrementitious in their nature.” 
In addition to the species of Scleroderma enumerated 
in my monograph (Trans. Ent. Soc. u.), the following 
have to be added to the genus :— - 
Scleroderma bicolor. (Plate V., fig. 1).
