NEUROTERUS PUXCTATUS. 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, b. 



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 cop3^ of the work, the following is given in extenso 

 from 'Brit. Pliyto. Hymen.,' vol. iv, p. 133 :

 176. Black ; legs flavous, upperside of hind coxse, 

 antennse except the first two or three joints, which 

 are lighter fuscous. Eyes not so large nor so promi- 

 nent as those of baccanim. Thorax : the mesonotum 

 trilobate, with deep furrows continued to the scutellum, 

 where the punctures are very shallow, the sides closely 

 punctured. Wings hyaline.

"At first it has all the appearance of Sjyather/aster 

 haccarum, but when closely examined the sculpture of 

 the thorax separates it from that species, and the wings 

 are free from fuscous clouds. 



" In baccarum the mesosternum is separated from the 

 mesonotum by a raised rounded ridge, much more
