Yorkshire Naturalists' Union : Annual Report, 1913. 31' 
being uninteresting, and shows that the resources of the county 
are by no means exhausted. A full list will appear later. An 
article from the pen of the secretary, drawing attention to the 
inadequate recognition of the Committee’s work in the x'eccntly 
published supplemental volume of “ Fowler’s Coleoptera ” has 
been published in The Naturalist. 
Hymenoptera, Diptera, and Hemiptera Committee. — Mr. 
W. Denison Roebuck reports that the Committee has received 
no information this season on any order but Hymenoptera 
Observations on Aculeata have been made at Roundhay by 
Mr. A. E. Bradley, at Leeds by Mr. A. Hodgson and Mr. W. 
Denison Roebuck, at Keighley by Mr. Rosse Butterfield, at 
Luddenden and Halifax by Air. H. Walsh, and at Selby by Mr. 
J. F. Musham. All agree that the season has not been very 
favourable, due to the unfavourable one of 1912. Of species of 
more than usual interest Mr. Walsh reports Halictus greygessnen 
in plenty, Crabro dimidiatus and Bombas jonellus about Ludden- 
den ; Mr. Butterfield Nomada ferruginata, N. lathburiana, 
Andrena helvola and A. analis about Keighley, and Mr. Bradley 
has detected Psithyrus quadricolor at Roundhay. Of other 
groups Mr. W. E. L. Wattam sent Sirex noctilio, taken in 
Huddersfield, and Mr. B. Morley has bred the following parasitic 
Hymenoptera : at Skelmanthorpe Pimpla alter nans from Boarmia 
repandata, Stenichncumon trilineatus from Abraxas grossulariat.a 
M acrocentrns infirmus from Dasypolia templi, Apanteles salebrosus 
from Pieris brassicce, and Amblyteles palliatorius from unknown 
host ; at Normanton Hcmiteles similis, hyperparasitic through 
an Apanteles from Emmelesia alchemillata and Lissonota sulphur i- 
fera, from Diantluecia carpophaga ; at Penistone Moors Barylypa 
insidiator from Acronycta menyanthidis ; and at Doncaster 
Microgaster connexus from Porthesia auriflua. A further York- 
shire example of Mutilla europcea has occvrred on Low Moor 
between Scarborough an:l Robin Hood’s Bay to Prof. A. G. Green. 
Some of the insects mentioned are new for Yorkshire. 
Neuroptera and Orthoptira. — Mr. G. T. Porritt writes 
1 have nothing of importance to record respecting the Neurop- 
tera, as the season for them seems to have been as bad 
as it was with the other orders of insects. Everything of interest 
respecting captures has already appeared in the pages of The 
Naturalist. One marked circumstance has been the excessive 
scarcity of the Lacewing flies ( Chrysopidce ). Of the local Chrysopa 
tenella, which some seasons is abundant in my garden, though 
looked for carefully, I did not see a single specimen either there 
or elsewhere. Indeed, I do not think I have seen half a dozen 
specimens of the genus the whole season. 
I have not attempted to do anything among the Orthoptera 
in Yorkshire, and the only record I have is from Mr. E. G. 
Bayford, who had a specimen of Periplaneta australasice brought 
19M Jan 1.
