412 NOTES ON NEW AND RARE LOCAL BEETLES. 



and identified ruficollis of Stepliens as 7iigriceps of Lacordaire. 

 Mr. Crotch again drew attention to these two doubtful species 

 of Stephens in his notes on the genus (The Entomologist, 

 vol. v., p. 7), but from that date onwards ruficollis, Steph. 

 (now identified as uielaiwcephala, Lat.) and 7'ufipes, F., have 

 disappeared from our list. I am informed, however, by Mr. 

 C. O. Waterhouse, who very kindly carefully examined the 

 species of Triplax in the Stephens collection at the British 

 Museum, that there are two undoubted specimens of rufipes, F., 

 one with the label Windsor; it is quite a distinct insect, as Mr. 

 Waterhouse says, more approaching Cyrtotriplax in form ; of 

 ruficollis there is one undoubted specimen, without locality, 

 but said to have been taken near Windsor. 



In view of the fact that the species of this genus are 

 excessively local, though when found they often occur in great 

 numbers, and that Mr. Bagnall has just discovered a species, 

 new to our list, in great abundance in a locality worked for 

 many years by that well-known collector Mr. Bold, I have 

 every hope that we may yet see the other two doubtful species 

 of Stephens restored to our list. It seems desirable, therefore, 

 to give a simple table for separating the European species 

 likely to occur in Great Britain. 



In his " Monograph on the Erotylidae" (1842), Lacordaire 

 described eleven European species, and Bedel in his " Mono- 

 graph " [I'Abeille, vol. v. (1868-69), P- A^ ^^so described 

 eleven species, but he sank two of Lacordaire's species into 

 varieties, namely, scutellaris, Charp., as a var. of bicoloi', Gyll., 

 and clavata, Lac, as a var. of nfipes, Fabr. ; in addition he 

 added two new species to Lacordaire's list, and made a few 

 changes in synonymy. 



In the European Catalogue of Heyden, Reitter, and Weise, 

 1 89 1, the genus contains fourteen species ; one of Bedel's 

 species, cyanesce?is, Bedel, is sunk as a synonym of marseuli, 

 Bedel, and there are in addition four new species not mentioned 

 by Bedel. I propose to confine my table to those species of 

 the European list which might be expected, from their 

 distribution on the Continent, to occur in Great Britain.
