request for an example of L. 4<-notatfr, taken at a tlrier station than those 

 usually associated with that species. L. 4i-notafa is certainly most niunerous 

 on Carices, but whether or not it also lives on grasses I have not jet 

 been able to detei'mine. 



Cixius simplex H.-S. 



Frons and clypeus black with pale keels. Crown twice as wide as long. 

 Pronotuni brownish-yellow, beliind the eyes as far as the side keels l>lcrk. 

 Scutellum black, the niiddlo keel and the base of the side keels reddi.sh. 

 I'^lytra lacteo-hyaline without black lines on the costa, in the female witli a 

 faiut ante-median brown baud ; veins chalk-wliite, the granules round or 

 roundish, sparingly ami regulaily placed, costal granules more than 12, dis- 

 tinctly larger than the remainder, none beyond the stigma. Apex of the malt* 

 Cauda produced beneath into an oblique piate about twice as wide as long, of 

 which each distal angle is a little expanded in the form of a broad triangular 

 tooth. Stj'les in the lateral aspect hatchet-shaped, i. e. having all the apical 

 expansion on the upper or cephalad side of the stalk. Aedeagus with a con- 

 spicuous falcate process inclining to the left on the distal or lower side of the 

 apex. Length 5-5-6*0 mm. 



One exam])le of each sex taken at Eastbourne in August 1914 by 

 Mr. F, M. Kobinson, and kindly ceded to me by Prof. J. W. Carr. 



The male is easily distinguished by the form of the genitalia ; the 

 female somewhat resembles that of C. nervosus, but is smaller and has 

 the costal granules much less pronounced.

LODERVS QILVIPES Klug: A SAWFLY NEW TO BRITAIN. 

 BT THE REV. E. D. MOEICE, M.A., F.Z.S. 



Five species of Loderus — a group formerly included in Dolerus, but 

 iyiow generally treated as a distinct genus — have been recorded from 

 Europe. Two of these species {palmatus Kl. and vestif/ialis Kl.) are 

 fairly well known, though not very common, members of the British 

 fauna. A third {pratorum Fall.) has occurred, so far as I know, twice 

 only in this country, and on both occasions almost in the same locality, 

 •having been taken first (about the year 18S3) by the late E. Saundei's 

 at Chobham, and afterwards by myself at Woking in May 1S97. 

 We may now add yet another species to our list, for I find in a 

 small boxful of Hymenoj)tera, taken last year by Dr. W. J. Fordham of 

 Sheffield in Lancashire and Yorkshire, a $ of L. (jllvipes Klug. It was 

 obtained, he tells me, by himself " by sweeping mixed herbage, Spiraea, 

 I'^mbellifers, etc." by the side of the liiver Brock (in Lancashire, _)ust
