Exhibitions, dtc. 



Mr. J. Hunter exhibited a Plusia, captured by Mr. Stock (who was present 

 as a Visitor) in the New Forest, and believed to be Plusia ni. (See Ent. Mo. 

 Mag. v. 107; Ent. Ann. 186'J, p. 124; 1870, frontisp. fig. 3.) 



Mr. Albert Miiller exhibited some insect-galls iu the flowers of the tansy : he 

 had received tliem in September from Mr. Dorville, in whose garden, near 

 Exeter, the growth of the plant was encouraged, from finding that flies, moths 

 and bees resort to it when the flowers are fresh. The galls had been submitted 

 to the author of ' Vegetable Teratology,' and Dr. IMaxwell Masters remarked 

 upon them as follows : — " It appears to me that the whole flower (floret rather) 

 has become hypertrophied, and at the same time the stamens, style and ovule 

 have entirely disappeared. I judge the structure to be an altered flower because 

 it springs from the axil of a bract or palea, and because at the summit are five 

 little teeth precisely like those of the corolla. In my book, for the most part, 

 insect deformities are passed over for two reasons ; one that I am quite ignorant 

 of Entomology, and the other that the changes produced by insects are often 

 so far foreign to the natural conformation as not to admit of comparison with it. 

 I should, however, have inserted your tansy under hypertrophy of the flower, 

 had I seen it previously." Mr. Miiller added that the perfect insect had not 

 yet been bred, but the larva showed it to belong to the Diptera, though not a 

 Cecidomyia. 



Mr. Pascoe exhibited specimens of Nepharis alata, Castelnau (Revue Zool. 

 1869), from King George's Sound, and observed that the insect described by 

 King, in the last Part of the Trans. Ent. Soc. N. S. Wales, under the name of 

 Hiketes thoracicus, was manifestly identical therewith, so that Mr. King's name 

 must sink as a synonym. By both authors the insect was referred to the 

 ColydiidtE, but Mr. Pascoe thought the genus would be more appropriately 

 placed near Mouotoma. 



Mr. Pascoe requested the opinion of Members on a point of nomenclature. 

 Dejean, in his Catalogue (cd. 1834j, proposed the name Diurus for a genus of 

 BrenthidiB; but no description was published until Pascoe himself gave the 

 generic characters in 1862. In 1852 Motschulsky described a genus of Tele- 

 phoridaj under the name Biurus, which in Gemminger and Harold's Catalogue 

 (1869) is changed to Diurus, thus clashing with the genus of BrenthidiB. And the 

 question was, for which of the two genera ought the name Diurus to be retained?
