Acy [February, 



the latter insects wore below normal size. The larvae of Notodonta dictaea 

 were fairly common on Pojndus canadetms and P. tremuln (pale green in colour 

 on the former, and mottled brown on the latter), and one larva of N. ziczac 

 occurred on aspen. Choreutes scintillulana was in swarms at Askern. Dr. 

 Oorbetl has also added Carpocapsa splendana (Doncaster), Adela rufimitrella 

 var. macnlata (Askern), and Oxyptilus teucrii (Hatiield) to the Yorkshire list. 

 This latter insect occurred commonly in July on wood-sage in an uncultivated 

 field. 



The report on Coleontera by Dr. W. J. Fordham, F.E.S., was brief, as a 

 complete list ot the results of the work of members of the Coleoptera Com- 

 mittee i-v usually published early in the following year in "The Naturalist," 

 and at the date of the meeting a great number of the insects taken had still to 

 be verified by the referees. There are, however, several interesting additions 

 to the county list, including Di/fiscus cireumjlexus, which occurred in fair 

 numbers near Hull, in company with the common D. punctulatus and D. mar- 

 yinalis. A few species of beetles occurred in large numbers, but the majority 

 of the committee have found a very great diminution in the numbers of species 

 usually common. 



For Hymenoptera, Mr. R. Butterfield, F.E.S., reports a disappointing year, 

 but the early spring bees were abundant. The event of the season has been 

 the discovery by Mr. A. E. Bradley oi Andrena ruficrus Nyl. in large numbers 

 near Leeds. The burrows occurred in the embankment of an old disused 

 reservoir and were mixed with those of A, clarkella. Mr. Bradley has found 

 Nomada fabriciana associated with ^H(^r(??/a anyustior at Adel, and Mr. Butter- 

 field found iV. lathburiana in great numbers towards the end of May in 

 Wharfedale associated with Andrena cineraria, but no males were seen. The 

 latter also records Andrena suhypaca Nyl. (new to the county) from Keighley 

 and Grassington, and Meyachile circumcincta from Bingley. Mr. Bradley has 

 found six nests of Vespa sylvestris underground. Fossorial Hy^nenoptera have 

 been rare, only common species of Crabro and Salius having been seen. A 

 few sawflies have been added to the county list, including three species of 

 the difficult genus Tenthredopsis and Pachyprotasis varieyatu. 



In Neiiroptera and Trichoptera, Mr. Porritt found little to report. Tinodes 

 aureola occurred in plenty about dripping rocks in July near Huddersfield, and 

 Stmophylax vibex was also takeu in the same district. Since the meeting, 

 Boreus hyemalis, a species new to the county list, has been taken by Mr. G. B. 

 Walsh at Scarborough, and by Mr. C. A. Cheetham at Austwick, in both cases 

 in November. 



In Biptera, Mr. C. A. Cheetham, F.F.S., reported that over 300 additions 

 had been made to the Yorkshire list, by field work during the year and by 

 research work among old collections and unpublished lists. Good collecting 

 days have been few, and Syrphidae have been scarce, with the exception of 

 those with aquatic larvae. Mosquitoes have had their share of attention, and 

 several new species have been added to the list, including the recently des- 

 cribed Theobaldia arctica Edw. 



Among the numerous exhibits may be mentioned the following : — 



Lepidaptera. — Mr. Porritt, a rayed form of Melanij^pe hastata from 

 Houley ; two specimens of Aplasia ononuria from Folkestone (from the Webb
