136 DRYOPID^ (PARNID.^). 



Norfolk : taken by Mr. James Edwards in three widely separated 

 localities, and introduced by him as British (Ent. Mo. Mag. xliv. 

 {•2 Ser. xix.) 1908, 102) ; Kidlington (Walker) ; Wellington College. 

 The species is probably common. 



Mr. Edwards gives figures of the sedeagus in the two allied species, 

 and, as a guide to every one wishing to examine the male characters, 

 points out that in the male the upper surface of the last dorsal 

 abdominal segment is evidently more pubescent than the remainder 

 of the dorsum, whereas this is not so in the female. 



The true synonymy and constitution of this species is not, 

 apparently, settled with any certainty. Dr. Sharp is of the opinion 

 that Mr. Edwards has confused two species under D. auriculatus 

 ( = the old prolifericornis of Erichson). 



D. (Parnus) anglicanus, Edwards (Ent. Mo. Mag. xlv. (2 Ser. 

 XX.) 1909, 21b). " Male similar in appearance to D. griseus, Er. ; 

 antennre at the base nearer to each other than either is to the eye ; 

 thorax equally narrowed in front and behind, the sides evenly curved 

 from the base to the apex ; tarsi red, with the apex of the claw joint 

 narrowly darker. iEdeagus subterete, in outline continuous with that 

 of the base of the paramera, the latter not swollen at the base, their 

 inner edges thin throughout, and their apices drawn out into a fine 

 point ; male organ cariniform in its basal half, the apical half forming a 

 subsagittif orm expansion. In what I believe to be the female the sides 

 of the thorax are distinctly straighter in the front half than they are 

 behind." L. 5-5J mm. 



Horning, Norfolk (Edwards). Taken in company with D. auricu- 

 latus, Fourc. {jwolifericornis, Fabr.) and included by him under this 

 species, until, on the authority of Sharp and Ganglbauer, he described 

 it as a new species {I.e. sivjn'a). The distinction of these closely allied 

 species by the characters of the redeagus may be correct, but raises 

 great difliculties for the ordinary student. 



It must be remembered that the D. prolifericornis, F., of our 

 collections is now called D. lurichis,'lS,r., and that our old B. auriculatus, 

 Panz., stands under the name of D. ernesti, Des Gozis. 



RIOLUS, Mulsant et Key. * 



The genus R'wlus must be regarded as distinct, and its members 

 may be separated from the species of Elmis, or Latelmis, as the genus 

 containing them is now called, by the absence of sublateral dorsal striae 

 on the thorax. 



Mr. Edwards (Ent. Mo. Mag, xlv. (2 Ser. xx.) 1909, 76) gives a 

 table of our species, as follows : 



I. Elytra with the fifth and seventh inter- 

 stices (sometimes the third also) distinctly 

 more elevated than the others.
