42 Yorkshire NatnraHsts' Union : Annual Report, 1917. 



I noticed a curious habit of Odynerus pictus ; on alighting 

 on a bloom of the common blue garden pansy, it immediately 

 slipped round to the rear of the bloom and remained there 

 until disturbed. What the attraction was I could not dis- 

 cover. 



Mr. Butterheld, Keighley, writes : — You are lucky to be 

 able to get so many species in your garden ; the species too are 

 of a distinctly lowland type, I do not know any one else who 

 has Anthophera, Megachile, Colletes and Posopis in this upland 

 district. 



For the Keighley district social wasps have not been 

 numerous, it is a number of years since they were so uncommon 

 here. 



The social bees have been fairly plentiful. Bomhus joneUus, 

 considered a rare bumble bee has been locally common, on the 

 other hand, I have not seen a single example of the sub-alpine 

 moor bee, Bombus lapponicus of late years. This, the most 

 handsome of our social bees, has gradually diminished in 

 numbers ; it would be interesting to get the opinion of other 

 observers, especially in the Whitby area. 



Among the solitary bees a special feature of the season has 

 been the large quantities of Nomada. The bright-banded 

 parasitic bees have arrested the attention of the least observant. 



The President of the Entomological Section and I saw a 

 large number in Shipley Glen. 



Amongst those captured were Nomada fabricinna L., 

 bifida Thoms., and lathhuriana Kirb. One day in June, 

 thousands were noted along the roadside between Bolton Abbey 

 and Beamsley, the species were chiefly N. alterata, Kirb., and 

 they were entering the burrows of Andrena rosce, var. trim- 

 mer an a. 



Worthy of mention is the occurrence of Halictus atricornis. 

 Smith, at Shipley Glen. 



The Medical Department of the Local Government Board 

 have asked for the assistance of Members of this Committee 

 regarding the movements of Anophelines in connection with 

 the possible risks of malaria being acquired in this country. 

 The circular sets forth the nature of the records required, 

 and copies, can be obtained by writing to the Medical Depart- 

 ment of the Local Government Board. 



In the Entomologist for August, 1917, Dr. J. W. H. Harrison 

 records the following new and rare Homoptera in the Northern 

 Counties : Livia juncaniim Latr., thinly distributed throughout 

 the Cleveland district of Yorkshire. 



Livia crefeldensis Minll., rare in the Middlesbrough area 

 of North Yorkshire. 



Rhinocola acenis L., rare, Gunnergate, Cleveland. New to 

 my Yorkshire list.
