shire Society of Natural Science, in two papers, viz., "Dimorphism 

 in Oak-galls and their Makers" in Vol. L, Part IV, 1883-4, and 

 " The Gall-making Hymenoptera of Scotland exclusive of those 

 that live on Oaks," in 1888. In the latter paper I inadvertently 

 omitted to refer to a record by Mr. P. Cameron ( Trans. Nat. 

 Hist. Soc, Glasgow. New Series, I., p. 297, 1887) of a gall on 

 Lathyrus macrorhizus, found near Kirkcaldy by Mr. Ewing, of 

 which I quote Mr. Cameron's description below. 



Ononis spinosa L. On Tents Moor in Fife, on the sandy 

 slope near the mouth of the River Eden, I found in the 

 beginning of August galls of a mite (Phytoptus). These 

 consisted in distortions of the buds, which were grouped 

 into clusters, or occurred singly here and there on low 

 stunted plants, among short herbage closely cropped by 

 rabbits. The affected buds individually may reach a 

 diameter of from 4 to 6 mm. ; but the whole mass of 

 buds may be from 20 to 30 mm. across. The leaves in 

 the buds remain small or abortive, while the stipules 

 seem little altered in size, or may even be enlarged. 

 The axillary buds are stimulated into growth ; but re- 

 main stunted. All parts are paler green than in the 

 healthy condition, and bear pale hairs among which the 

 mites live. Usually only certain branches on the plants 

 were altered, the others remaining healthy. This gall 

 has been recorded by several writers on the Continent 

 of Europe, of whom the first was Dr. Thomas (Nova 

 Acta, Leop.-Carol. Akad. 1876, p. 262, pi. II. f. 11), 

 who described it from material on O. spinosa in Prof. 

 Braun's herbarium from Carlsruhe, and from fresh 

 specimens found by himself on O. repens near Jena, and 

 by Prof. Magnus near Warnemiinde. Dr. Low has ob- 

 served it on O. spinosa in Austria ; Dr. Schlechtendal 

 on the same plant at Merseburg ; and Herr Liebel on 

 both species in Lorraine ; hence it is evidently widely 

 spread in Central Europe. 



Vicia hirsuta Koch. On this vetch I found, in August, near 

 St. Andrews, galls that were evidently the work of a 

 Weevil, and probably belong to Apion GyllenhaUii 

 Schk. already recorded by myself in this Journal as
