years, but unsuccessfully hitherto. The metamorphosis is per- 

 formed under the ground. The gall splits to give exit to the 

 grub, which worms its way into the soil. The larva is yellowish 

 red ; the imago is described, by those who have been fortunate 

 enough to rear it, as dingy yellow. On the Continent, according 

 to Kaltenbach, the gnat affects G. molliigo and G. uliginosum, as 

 well as G. verum. 



Cecidomyia clausilia, Bouche, began to emerge from the mar- 

 ginal pads on the leaves of Salix alba on Aug. 5 th, and continued 

 to emerge till fully the middle of the month. This species, though 

 its home is figured by Brenii, was never reared by him ; indeed, 

 the rolled leaves were regarded as the work of a Phytoptus by 

 later writers. Breuii figured the nidus of the gnat in 1847; it 

 appeared in the ' Transactions of the Swiss Natural History 

 Society.' The home of a near ally of clausilia, viz., G. marginem- 

 torquens, is figured b}' Bremi on the same plate. This he reared 

 in the summer, he says, in fair abundance. Like clausilia, it also 

 pupated within the curl, though in the former the rolled-in edge 

 was continuous, in the latter interrupted. I must have reared 

 (Aug. 5th) fifty examples of clausilia from the affected leaves I 

 gathered. 



On August 28th I noticed the swollen buds of Rumex aceto- 

 sella, the home of C. rumicis, H. Loew. On being brought into 

 the house the larvae escaped from the buds ; further observation 

 with a lens revealed tiny white cocoons in each flower-bud. Dr. 

 Trail, of Aberdeen, says the " Cecids are very easily reared from 

 them."

ON BREEDING VARIETIES OF ANGERONA PRUNARIA. 

 By Geo. J. Grapes. 



Since writing the last notes on this subject (Entom. xix. 30^) 

 I have ascertained that the larvse given by me to a friend in 

 March, 1885, produced some pretty banded forms, including 

 instances in which the wings of the male were crossed with 

 yellow, instead of the usual orange bands. This seems unac- 

 countable, considering that the parents were typical male and
