Exhibitions, Sc. 



The Rev. Dr. Walker exhibited a long and varied series of 

 forms of Crymodes exulis, collected in June and July last in 

 Iceland. Li reply to a question by Lord Walsingham as to 

 whether all the forms referred by Dr. Walker to Crymodes 

 exulis had been identified as belonging to that species, Mr. 

 Kirby said the species was a very variable one, and that 

 several forms had been described from Labrador and Green- 

 land. Mr. South stated that he had examined Dr. Walker's 

 specimens, and he believed that most of the forms exhibited 

 had been described by Dr. Staudinger in his papers on the 

 Entomology of Iceland. 



Dr. Sharp exhibited a specimen of Ornithomyia avicularia, 

 L., taken near Dartford, to which there were firmly adhering 

 — apparently by their mandibles — several specimens of a 

 mallophagous insect. He also exhibited some specimens of 

 fragile Diptera, Neuroptera, and Lepidoptera, to show that 

 the terminal segments in both sexes might be dissected off 

 and mounted separately without the structures suffering from 

 shrivelling or distortion. Dr. Sharp also said, in reference 

 to the statement made by him, on p. 421 of his paper recently 

 published in the ' Transactions ' of the Society, as to the 

 number of the segments of the abdomen, and the position of 

 the genital orifice in the female of Hemiptera-Heteroptera, 

 that he had recently been making some dissections, and found 

 that the structures externally were difficult of comprehension, 

 and he now thought that the statement he had made from 

 observation, without dissection, might prove to be erroneous. 



Mr. Gr. F. Hampson exhibited and remarked on a series of 

 Erebia melas, taken in July last, in the Austrian Alps (Dolo- 

 mites), by Mrs. Nicholls. Mr. Elwes observed that though
