THE ESSEX FIELD CLUB. 315 Mr. E. T. Newton exhibited a metacarpal bone of an ox, from near Cromer, which had been curiously gnawed by rodents. Mr. Nicholson exhibited a nest of Vespa germanica, which he had taken from the clayey bank of a pond at Oak Hill, Woodford, on October 24th, 1920. He also exhibited specimens of various parasites or commensals of wasps and their nests, including the beetle Metaecus paradoxus, larvae of another beetle, a species of Cryptophagus, some mites (Glycyphagus), the ichneumonid Sphecophaga vesparum, and the dipteron Volucella pellucens. The President exhibited a large series of British lichens which, as dupli- cate specimens from the national collection, had been that morning granted to the Club's Museum by the Trustees of the British Museum. Mr. J. H. Owen then gave a lecture entitled "Further Notes on the Sparrow-Hawk," which he illustrated by a series of some 80 lantern photo- graphs of exceptional merit. At the close of a very interesting lecture, a discussion ensued, in which Messrs. Miller Christy, Glegg, Horn and Thompson, and Miss Hibbert-Ware, took part ; and Mr. Owen replied to the numerous questions asked. A hearty vote of thanks was passed to Mr. Owen for his lecture, and the meeting terminated. EASTER VISIT TO COLCHESTER (527th Meeting). Thursday, 24TH March to Monday, 28th March, 1921.
