I seldom went there without obtainiut^ one or more of the insect, and 

 this autumn it could again be taken in the locality. The sexes are 

 much alike, except in their antennae, those of the male being rather 

 long and pointed, and largely yellow, those of the female quite black, 

 short and oval. Previous captures seem invariably to have been asso- 

 ciated with the common reed, but the plant is plainly not essential, and 

 as a matter of fact it does not grow within miles of the Herefordsiiire 

 locality. The idea, too, that cinereus emerges in the winter is not 

 altogether right, rather it is an early autumnal species, holding 

 on through the winter into the spring. 



Campsicnemus marginatus. On September 15th, 1913, I took on 

 the Monnow a female of this rare species, my three pi'evious captures 

 having been all males. Marginatus can be pretty easily recognised 

 when turned out of the cyanide bottle by the darkened X-vein and 

 darkened costal half, roughly speaking, of the wings. It is besides 

 absolutely dull on frons and thorax, with the face brilliantly white 

 and widely dilated in its lower half. 



Porpliyrops nasuta. Of this rare species I took a single male on 

 the banks of the Wye at Fownhope, a few miles below Hereford, on 

 August 18th, 11)13. 



Porphyrops frada. Until the capture of the example I'ecorded 

 above, a male of this sjDecies had represented nasuta in my collection. 

 It was taken on the Monnow as far back as July 13th, 1911. Like 

 the Scotch specimens taken by Col. Yerbuiy, the cubital vein is neither 

 bent nor broken. But a character that at once distinguishes it is the 

 thick fringe of long black postocmlar hairs which come curling forward 

 like whiskers and project some distance beyond the eyes. 



Herefordshire is particularly rich in the genus Por])hyrops. 

 Besides the above, spinicoxa and crassipes are, of course, common, and 

 of general distribution. Nemoram is widely distributed, and can 

 hardly be called scarce ; micans is eqiially distributed, but less fre- 

 quently met with ; rivalis, riparia, and penicillata are all to be taken 

 on the shingly reaches of the Monnow, whilst antemiata and elegantula. 

 seem confined to the muddy reedy pools of Moccas and the Leech 

 Pool. Antennata has only been taken once, and that was at the Leech 

 Pool by Col. Yerbury. Elegantnla also occurs there, but is more 

 common at Moccas, where at tlie shallow end of the pool it may 

 often be swept throughout July and the early part of August.
