and our doubtful examples (of which there are very many) require to 

 be carefully compared with authentic European co-types. We hope 

 that one of our many students of the group will soon undertake the 

 task. We cannot here do more than indicate a few corrections with 

 regard to synonymy, &c. 



L. niger, Koch. It is very doubtful whether we possess the true 

 Z. oiiger, Koch., and for the present, at all events, the species should be 

 omitted from our lists ; the very few examples should most probably 

 belong to L. luridus. 



L. castaneus, Duft., and L. brunneus, Duft., are synonymous 

 and the latter name must stand. L. brunneus may be distinguished 

 from L. luridus as follows (Bedel. Faune. Col. Seine, 190): 



I. Elytra with several long curved cilia towards 



the extremity of their external margin, and 

 a single longer and upright hair at their 

 apical angle ...... L. bruxneus, Buft. 



castaneus, Duft. 



II. Elytra with no cilia, or very short ones, at 



their apex ....... L. luridus, Scop. 



[L. nigerrimus, Gyll. (Ins. Suec. iv. App. G56 ; Weise, Naturg. 

 Insect. Deutsch. vi. 943). A shining, entirely black, convex species, 

 with or without a slight feneous reflection ; tarsi pitchy ; antennse 

 slender, with the fourth joint just a little longer than the third ; head 

 very finely sculptured ; thorax sparingly punctured in the middle, more 

 closely towards base, the punctuation being rather coarse ; elytra with 

 evenly rounded sides and well-marked shoulders, closely, evenly, and 

 comparatively strongly punctured, suture more or less depressed behind, 

 sutural angles right angles, spur of posterior tibise long. L. 2^ mm. 



Cleethorpes, Lincolnshire ; taken by Dr. W. Wallace, of Grimsby, 

 by sweeping at night on September 7, 190" ; in INIr. Tomlin's collection 

 there is a specimen labelled " Greathide " (Joy, Ent. Mo. ]\Iag. xliv, 

 (2 Ser. xix.) 1908, 104). 



The species may be known by its deep black colour, large .size, and 

 comparatively strong and even punctuation of the elytra ; the thorax 

 is sometimes almost smooth ; apparently smaller specimens are found 

 on the Continent, as Weise gives the size as 1*5 to 2*2 mm. I have not 

 seen a Continental specimen of L. niyerrimus, and feel somewhat doubt- 

 ful as to the identification of the species. Weise compares it with 

 L. holsaticus, and says that the species are so close to one another that 

 the}" might be confused ; the insect, however, desci'ibed above is totally 

 difiei'ent from L. holsaticus in colour, shape, and punctuation, and could 

 not in any way be mistaken for it.] 



Since writing the above Mr. Donisthorpe says that the insect above 

 -described is only a variety of L. Iu7'idus, as, in company with Dr. 

 Wallace, he has taken this insect and L. luridus and all the intermediate
