gall, but on the gall itself, but the two never, so far as 1 am aware, come to ma- 

 turity together. From observations I have made during the past season I have 

 no doubt whatever but that the Cynips is destroyed either.in the e^g or as a very- 

 young larva, and that the " guest ' gall fly lives on ihe juices of the gall, but in 

 what manner the host is killed I could not discover. May it not be destroyed 

 by the female Synergus when she is depositing her eggs in the gall.- Id. 



Biorhiza renum H., near Glasgow —The galls of Biorkiza re/fum, H. are 

 abundant in the woods near Glasgow. Cynips radicis, Fab. also occurs. — Id. 



Two New British. Hemiptera.— [ captured in Braemar, in 1871, two 

 bugs which I suspected were additions to the British list, as they did not agree 

 with the descriptions of any recorded British species. I have lately taken 

 Mr. J. W. Couglas s four great British authority on these insects) opinion, and 

 he informs me that they may probably be referred to Salda viargi/ie/la H.S. 

 and Phytocoris pini Kirschb. — F. Buchanan White. 



Hemiptera in Harris. — During a visit to Tarbert in Harris, in the spring 

 of 1872, I took on 25th April, Corixa Scotti (abundantly), Gerris costce, and 

 Velia currens. — H. Tenner Fust, Junr., Hill Court Gloucestershire. 



Dicrorampha herbosana Barrett, an additio to the Scotti hList. - I 

 captured this insect in considerable numbers during the month of Julv, 1872, on 

 the Gienniffer Braes near Paisley. It has also been taken on the hills above 

 Port Glasgow by Mr Peebles, and in the neighbourhood of Glasgow by Mr. 

 King. I might also mention that I have taken a second specimen of Mixodia 

 Bouchardana in a pine wood near Paisley- John Dunsmore, Castlehead, 

 Paisley. 



Sericomyia superbiens Miller —This insect is not indicated as occurring 

 in Scotland by Mr Walker in his work on British Diptera. I captured one in 

 the month of August seven or eight years ago, at Woodhouselea in the Pent- 

 lands. The only other place I have caught it was in the English Lake district. —

"TOURING the summer, large blanched or withered spaces 

 ^■^ are conspicuous everywhere on the upper surface of the 

 leaves of the common dock (Rumex obtusijolius J, which when 

 closely inspected are perceived to arise from the detachment of 

 the cuticle, and the destruction of the subjacent layer of green 

 matter ; while the inferior portion of the leaf remains unaltered. 

 In these blotches the loose skin is slightly puffed up by the
