fact. The type-species of Diurus was origiually published (by a misprint) under the 

 specific name turcillatus (Schonh. Cure. i. 359). It is true the error was corrected seven 

 years later (Schonh. Cure. v. 510) ; but of course that goes for nothing, and an intelligent 

 posterity is expected to acquiesce in the perpetuation of Diurus turcillatus I to welcome 

 this typographo-diabolical Turklet, and immortalize this two-tailed bashaw ! — J. W. D.

Exhibitions, dc. 



Prof. Westwood exhibited a number of locusts, which formerly belonged to 

 the collections of seme of the principal entomologists in the early part of the 

 century, and which still bore the labels of those entomologists " migratoria, 

 Linn." These insects, however, were not the migratoria of Fischer, but were 

 the cinerascens of Fabricius and Fischer, of which Christii of Curtis was only 

 a synonym. The principal distinguishing character was the form of the 

 pronotum, which in one was narrowed before the middle, and almost flat on 

 the top, but in the other was of equal breadth throughout, and arched on the 

 top, with the dorsal carina more raised and prominent. Prof. Westwood 

 remarked that tradition and old specimens were, on a point of this kind, of 

 more importance than figures in antique works, and he thought Fischer had 

 made a mistake, and applied the name migratoria to the wrong insect. On the 

 evidence afforded by these old specimens, he suggested that the true migratoria 

 of Linne was not the locust with a flat or but slightly cariuate pronotum, 

 constricted in front, but the locust with an arched pronotum, with the crest or 

 median ridge higher and more produced in front. 



Mr, F, Smith said that, in consequence of a doubt expressed by Prof, West- 

 wood at a'previous Meeting, he had written to Prof, Stal, of Stockholm, who 

 informed him that the insect placed in the Stockholm Museum as the migtatoria
