462 APPENDIX. 



little nearer the middle ; the markings, according to Kuwert, are reddish 

 in H. flexuosus and yellow in //. femoralis, but this is not worth much 

 as a character. I have only seen one specimen of the true H. femoralis, 

 which was sent me by Mr. E. Waterhouse (without locality) and 

 named by Herr Kuwert ; it certainly looks very different from H. 

 flexuosus, being shorter, smaller and duller, with the general colour 

 dark and the markings hardly visible ; //. flexuosus is apparently a 

 rather common British species, but it appears to be rarer on the 

 continent, and Herr Kuwert says that he only possesses one specimen 

 of it, from Morlaix ; H. femoralis would seem to be rare in Britain, 

 but there still appears to be considerable confusion with regard to it, 

 and considerable doubt as to what really is the true, H. femoralis of 

 Kiesenwetter ; Herr Kuwert a short while ago sent me a specimen 

 named //. femoralis from Pomerania, and now writes concerning it 

 that he is inclined to believe "that the femoralis from Pomerania, 

 which has the legs paler and is larger, may perhaps be the arenarius 

 of Kiesenwetter." With regard to H. arenarius, I cannot discover an 

 authentic British specimen ; I believe that light examples of flexuosus 

 and lievigatus are made to do duty for it ; the following is Kuwert's 

 account of the species : " A little larger than femoralis. According to 

 Kiesenwetter (I have no examples to refer to) in colour, markings and 

 pubescence it comes half way between salinus and femoralis, but the 

 colouring is brighter and the legs are entirely yellow ;" the only 

 locality he gives is Ireland ; as, however, I have pointed out (Vol. III. 

 p. 386), Mr. Crotch came to the conclusion that the Irish specimens did 

 not differ materially from femoralis ; I believe, therefore, that //. arena- 

 rius should be regarded merely as a synonym of the last named species. 



Among the insects which I sent to Herr Kuwert are specimens named 

 H. rcctus, Wat., from Mr. Waterhouse's and Mr. Champion's collections ; 

 these he is inclined to regard as a new A r ariety or species, and proposes 

 that they should be described by me as intermedius, n. sp., as being 

 intermediate between H. salinus and //. fossor ; I prefer to consider 

 them as a variety of H. salinus ; Kuwert was not, apparently, aware 

 that the insect had been described, but, apart from this, there is a 

 species of Kicsenwetter's already in existence, named intermedius, which 

 comes near hispidulus, Kies.* 



//. salinus is a rather large species (6-7 mm.), parallel, with bright 

 yellow markings and legs entirely yellow ; the elytra are twice as long 

 as together broad ; the thorax is short, with the sides strongly rounded 

 and the margins more or less broadly yellow ; the club of the antennae 

 is somewhat long ; the colouring is variable, and the pubescence thick : 

 the variety rectus differs in being smaller, with the antennae darker, 

 and the legs dark instead of light ; it also has, in the male, two small, 



* Since I wrote the above I have received a letter from Herr Kuwert in which he 

 says that he meant to propose " intermissus " as the name, but wrote " intermedius "
