NEUROTERUS PUNCTATUS. 125 
appear, at first pink, then red, crimson, and ultimately 
dark brown. The spots have then become slightly 
elevated, and soon afterwards the colour fades into 
harmony with the remainder of the gall as it finally 
assumes a yellowish-brown hue. 
The gall structure is moderately hard, and contains 
a relatively large larval cavity without an inner gall. 
It is subject to considerable variation in shape and 
size; features which are mainly due to the presence of 
parasites. Depth of colour appears to depend upon 
exposure to the sun. 
A gall occasionally develops on the upper surface of 
a leaf. See Plate L, s. 
Neuroterus punctatus, Cameron. 
The gall produced by this species is most obscurely 
situated. I have no record of its occurrence, and I 
regret inability to describe or illustrate it. 
For the guidance of the gallist who might capture 
the imago, or wish to search for the gall; and also for 
the student who does not possess, nor have access to, 
a copy of the work, the following is given in extenso 
from ‘ Brit. Phyto. Hymen.,’ vol. iv, p. 183: 
“ Spathegaster punctatus, Bignell, u.M.M., ii (2) 
176. Black; legs flavous, upperside of hind coxe, 
antenne except the first two or three joints, which 
are lighter fuscous. Eyes not so large nor so promi- 
nent as those of baccarwm. Thorax: the mesonotum 
‘trilobate, with deep furrows continued to the scutellum, 
where the punctures are very shallow, the sides closely 
punctured. Wings hyaline. 
“ Length 2°5 mm. 
“ At first it has all the appearance of Spathegaster 
baccarum, but when closely examined the sculpture of 
the thorax separates it from that species, and the wings 
are free from fuscous clouds. 
“Tn baccarwm the mesosternum is separated from the 
mesonotum by a raised rounded ridge, much more
