large area, jjlacetl so that one half of it is exposed upwardly, while the 

 other is turned to the uuder-side. The difPereuce between these two 

 elytra is in fact very strong, and may be expressed in various ways. 

 But from the facts I have mentioned it is clear that G-anglbauer and 

 others are wrong in saying that the epipleuron is large in riigosus, for 

 it is really reduced and replaced in appearance by the tenth interstice, 

 which forms a pseudepipleuron. 



I should mention that I am not the first to take this view, as it 

 was pointed out by Seidlitz many years ago in his " Fauna baltica." 



The other genera I have adopted show important modifications of 

 these points of structure, and prove amongst other things that the 

 symmetrical form of the last joint of the maxillary palpi (which appears 

 at first of infinitesimal importance) is an indication of real affinity, it 

 being common to all the genera except Helophorus and Mecjheloiiliorus . 

 In fact it shows that Airadhelopliorus hrevipalpis is naturally generically 

 distinct from the forms witli which it has hithei*to been always associated 

 — indeed, has been often considered merely a specific variation. J'he 

 epipleuron of hrevipal'pis is much reduced as compared with the 

 forms with which it is confounded. I am hei'e anticipating what 

 I shall' have to point out later for the reason that I fear I shall be 

 prejudiced because many will think it impossible that two insects they 

 have failed to distinguish as species can be correctly placed in different 

 genera.

COLEOPTERA IN HEREFORDSHIRE (V).

The preceding paper of this series appeared in the Ent. Mo. Mag., 

 1911, pp. 271-273. 



In the following list all are additions to the county list with the 

 single exception of Bembidiuvi fl%iviatile, which is recorded in the 

 " Victoria County History " for Herefordshire without more exact 

 locality.* I am able to say that the locality was Eardisley. 



Many of the records now given are due, it will be noticed, to the 

 late Dr. J. H. Wood of Tarrington, and I cannot ref i-ain from endorsing 



* In the " Eiitomologist'.s Annual" for 1S72, p. 47, Mr. K^ C. Hyo records tlie captuio by 

 Dr. Power of " BruihidiuM fluviatUe on the banks of the Wye (a new locality)."— .J.J. W.
