1 6 Field Notes. 



by two or even three worms. While under observation it was 

 noticed that the worms after emerging, retained a hold on 

 the Chironomus, and imbibed the juice or blood of the insect. 

 A drop of this fluid on the side of the glass tube was of a 

 reddish colour, but when the worm became detached im- 

 mediately changed to a green similar in tinge to the colour 

 of the worm. 



Problems remain as whether Chironomids with plumed 

 antennae and male genitalia can be found infested with these 

 parasites, and if so, at what stage of existence the worms 

 begin their attack, and if on the larv?e, how it happens that 

 the antennae are affected. 



ENTOMOLOGY. 



Boreus hyemalis in Yorkshire . — Looking over some 

 mosses on limestone walls at the foot of Smearsett, on Nov. 

 14th, 1920, I found a specimen of Boreus hyemalis. This near 

 but wingless relative of the Scorpion Fly, Panorpa communis, 

 does not seem to have been previously recorded for Yorkshire ; 

 but Mr. G. T. Porritt informs me that Mr. Walsh has recently 

 taken it near Scarborough [see below] .^Chris A. Cheetham. 



Forficula auricularia L. var. forcipata Steph. in 



Yorkshire. — To the localities for this interesting male form 

 {antea, p. 362) can now be added the East Riding ; a single 

 dead specimen occurred to me on October 25th under a plant 

 of Erodium in a sand-pit near Flixton. Under the same 

 plant occurred also an example of the weevil Phytonomiis 

 fasciculatus Herbst. The only other known Yorkshire locality 

 is Spurn, where Mr. T. Stainforth and I took several specimens 

 last year. — Geo. B. Walsh, B.Sc, Scarborough. 



The var. forcipata of F . auricularia is not rare, and probably 

 occurs among an abundance of the type in any locality. —

Boreus hyemalis L. — A New Yorkshire Neuropteron. 

 — On November 6th, while^ working moss on Hay Brow, 

 near Scalby, for the beetle' Mniophila muscorum Koch, I 

 took a pair of the curious Panorpid Boreus hyemalis L., the 

 female nearly escaping by its powers of jumping. This is 

 apparently a new Yorkshire record ; in any case the insect 

 seems to be extremely local, for these are the first specimens 

 I have ever seen alive. — ^Geo. B. Walsh, B.Sc, Scarborough. 



Boreus hyemalis is a most interesting addition to the York- 

 shire List, as it has been recorded from but few localities in 

 England. More specimens have been taken in Scotland, 

 but it has always been regarded somewhat as a rarity in 

 Britain.— G. T. P.
