relatively, more robust ; the antennEe, especially, being stouter, the joints more 

 cylindrical, squarely truncated at the apex and tipped with black ; the last joint 

 is scarcely as long as the preceding and tapers to a fine point ; the eyes are smaller, 

 narrower, a little less approximate beneath and, relatively, more coarsely facetted ; 

 the punctuation of the head, prothorax and under-side is much stronger, coarser and 

 closer ; the hind tihice are straight. Long. 3^ lines. 



Sab. : Peru ; a single example. 



In the strong and close punctuation of the head and prothorax 

 this species assimilates itself to Chorasmius procerus ; but, whilst in 

 Gliorasmius the antennae are as in Aryenis rufescens — with the ma- 

 jority of the joints elongate-obconic and sub-nodose at the apex — in 

 the present species these organs more closely approach the form seen 

 in Evaniosomus, having the joints relatively stouter, shorter, sub- 

 cylindrical, and truncated at the apex. 



The large, sub-prominent eyes, approximate beneath, the sub- 

 cyliudrical prothorax, and the presence of wings, clearly associate the 

 present species with A. rufescens. 



CnoEASMiFS, mild. 



To the characters already pointed out by me (Trans. Ent. Soc, 

 1868, p. 310, note) as separating this genus from Evaniosomus, it is 

 necessary to add, that the elytra are entirely margined at the base.

Hote on the occurrence in JEngland of Anisotoma brunnea (Sturm), Er., a 

 distinct species from A. obesa, Schmidt. — Among an enormous niunber (nearly 300 !) 

 of examples of various species of Anisotoma recently taken by my valued corres- 

 pondent, Mr. R. Lawson, out of flood refuse near Scarborough, and kindly sent to 

 me for examination, I find a few individuals, of both sexes, which are evidently to be 

 referred to a very distinct species, and one certainly not as yet recorded as British. 

 This I cannot think to be any other than Erichson's exposition (Ins. Deutschl. ill, 

 p. 72) of A. brunnea, Sturm, attributed by Dr. Kraatz (in Stettin, ent. Zeit. xiii, 

 p. 379) to obesa, Schmidt, as a small form ; an opinion in which he has hitherto 

 been followed by all writers. I feel sure, however, from the characters mentioned 

 by Erichson for A. brunnea, and from these specimens of Mr. Lawson's agreeing so 

 exactly in every respect therewith, that Dr. Kraatz must have been misled by some 

 confusion in Erichson's real or supposed exponents of A. brunnea. Dr. Kraatz's 

 opinion is apparently founded on the fact that the words of Erichson's descriptions 

 of the two insects are in some instances applicable to both. But, on Dr. Kraatz's own 

 shewing, the two are quite distinct, for he emphatically points out the strong and 

 somewhat distant punctuation of the stria? as a character for obesa ; whereas 

 Erichson states that in brunnea it is " meist ziemlich dicht und fein." Besides this 

 important discrepancy, Erichson's obesa is If lin. long, in the section with strongly 

 i dilated anterior tibiae, convex, with an ample thorax and the 3rd joint of its antennae
