24 Yorkshire Naturalists' Union : Annual Report, 191 1. 



Mr. J. Porter records what he regards as an immigration of 

 „P. hrassiccB at Hull. About the end of July these insects appeared 

 in thousands, but fortunately very few larvae resulted. 



Mr. Morley records three specimens of A^. aurago from Skel- 

 manthorpe, and melanic H. defoliaria and aurantiaria (taken by 

 himself), and black A. menyanthidis (taken by Mr. H. Dyson), 

 are reported from the same district. 



A. atropos has occurred in the larval state at Barnsley 

 '{Whitaker), and imagines have been captured at Shepley (Stephen- 

 son), and Middlestown, a fine melanic specimen (Hooper). Mr. 

 H. Lodge records the capture of a fine specimen of Deilephila 

 livornica at Normanton. Mr. J. F. Musham comments on the un- 

 usual abundance of P. rapce, C. phleas, V. tirticoe, and E. hyper- 

 anthtis, in the Selby district. 



Neuroptera and Trichoptera. — Mr. G. T. Porritt writes : — 

 From a Neuropterist's point of view, the most interesting county 

 event was the finding of the fine and local dragon-fly Lihelhda 

 fiilva by Mr. Corbett at Shirley Pool, near Askern, at the beginning 

 of June. Some ten days later Mr. Corbett kindly took me to the 

 place, when the species was still out in abundance, and the sight 

 of so many on the wing, together with the natural beauty of the 

 spot, was a delight long to be remembered. 



With it were Libellula quadriniacidata and Brachytron pra- 

 tense (a good species), less commonly, but yet in fair numbers ; 

 and of the smaller members of the order Pyrrhosoma nymphula, 

 Ischnura elegans, and Agrion puella. 



Other noteworthy Neuroptera and Trichoptera during the 

 year were Nemoura prcecox, which I again found in Harden 

 Clough, Huddersfield, on April 15th ; and in the same locality 

 Hemerobitis atrifrons, H. orotyp^ls, and Rhyacophila obliterata, the 

 first mentioned being new to the Huddersfield district, occurred 

 on the Union's excursion there on September gth. 



At the Union's excursion at Ingleton, on August 7th, I was 

 glad to find Neureclipsis himaculata, thus making a second York- 

 shire locality ; and there also Hemerohius orotypus occurred. 

 Lastly, among some Trichoptera taken by the Rev. Cyril D. Ash, 

 at Saxton, near Tadcaster, were three specimens of Limnophilus 

 politus, making a second county locality for that insect also. 



Coleoptera Committee. — Mr. H. H. Corbett writes : — The 

 season, from a collector's point of view, was very bad ; beetles 

 being few in both species and numbers. Notwithstanding, many 

 interesting additions to the county list have been made, of which 

 the following is a list.: — Bemhidinm hipunctatum L., Hydroporus 

 longiilns Muls., Helophortts arvernictisMuls., Hydrochtts angustatus 

 ,Germ., Stenus nitens Steph., Acntlia inflata Gyll., Siipha dispar 

 Herbst., Lcemophlceus pusillus Sch., Psammcechus bipunctatus 

 F., Monotonia spinicollis Aube., Ennearthron cormitum G3'll., 

 Clytus arcuatus L., Saperda carcharias L., Bruchus sp. ? This 

 last insect is still unnamed, and possibly may be new to science.
