amongst Lepidopterists, and is a model of what such a list should be. 

 His generosity iu distributing among his fellow-workers the rare and 

 interesting species found by him in the district, to name only such as 

 Clostera anachoreta and Ohortodes bondii (the latter species described 

 by himself) is by no means forgotten. 



His widow, one son, and five married daughters survive him, and 

 it is to the kindness of the former that we owe the very characteristic

TWO NEW BRITISH BEETLES. 

 BY NORMAN II. JOT, M.R.C.S., F.E.S. 



PllILONTHUS CONCINNUS, Grav. 



It is quite evident that most of the specimens of PJtilonthus 

 standing under the name ebeninus, Grav., in our collections really 

 belong to the allied species, P. concinnus, Grav. I have myself only 

 seen one British example of P. ebeninus (not including the so-called 

 v. corruscus, Grav.), which is in Mr. Tomlin's collection, labelled "ex. 

 Coll. Harris." * P. concinnus is a very common insect on the con- 

 tinent. The distinctions between the two species given hy Ganglbauer 

 are the following : — P. concinnus is smaller than P. ebeninus (5 — 7 

 mm. as against 7'5 — S mm.) ; the penultimate joints of the antenna* 

 are distinctly more transverse, and the hind body is more finely and 

 closely punctured. In P. ebeninus the fine transverse impressed 

 line at the base of the first three or four dorsal segments of the 

 abdomen is sharply angled backwards in the centre; in P. concinnus 

 it is quite straight, or at most only slightly angled. The v. ochropus 

 mentioned by Canon Fowler is a variety of P. concinnus. 



Ganglbauer describes P. corruscus, Grav., as a good species, 

 although he remarks that it is very likely only a variety of P. ebeninus. 

 I think it is best to regard such a distinct-looking form as a good 

 species, unless there is some biological evidence that it is only a 

 variety. 



OXYPODA PERPLEXA, Muls. 



Mr. Britten pointed out to me some time ago that a specimen of 

 Oxypoda exoleta, Erichs., he had from the Cumberland coast did not 

 agree with one which I had given him under the same name. 



As I was unable to find out which of the two was the true 



* I have the true P. ebeninus from Godalming and Sandown, I. W. — G. C. C.
