Prof. Aurivillius, who has kindly examined Thunberg mutilated 

 type for me, informs me that it is certainly a Brotlieus and clearly 

 identical with deyrimatiis , Boh., so far as could be judged from the 

 elytra alone. As the latter insect agrees very well with Thunberg's 

 description also, I have little hesitation in accepting this suggestion 

 as correct. The type of deprimatus is certainly conspecific with 

 Marsham's porcatus, which he described from a single specimen 

 found by Lee at the root of a bulb of Ornithogallum in his garden in 

 Hammersmith, then a suburb of London. With the exception of 

 occlusus, Pasc, this is the only species which has the four pro- 

 jecting tubercles at the base of the elytra — a character which occurs 

 also in Euryxena hruchoides, Pasc. From occlusus the species may 

 be distinguished by the structure of the thorax, as well as by its 

 sharply angulate shoulders. 



11. Brotheus pumilus, sp. nov. 

 Plate VI., fig. 13. 



Long. 2J ; lat. 1-|- mm. 



Colour entirely dull black, without setae. 



Head with two large shallow impressions. Prothorax about as 

 long as broad, the sides subangulated behind middle, more narrowed 

 towards the apex than towards the base ; upper surface rugose, set 

 with small tubercles, arranged roughly in three transverse rows of 

 four each. Elytra short, transverse, the basal margin sinuate and 

 not broader than the base of the prothorax, shoulders prominent and 

 subrectangular, the sides parallel to the declivity, which is very 

 abrupt, depressed and enclosed on all sides by a transverse carina 

 so as to form a regular pentagon ; upper surface with a sharply 

 elevated curved carina running obliquely from near the shoulder and 

 meeting the posterior carina much nearer to the suture than to the 

 dorsal margin, a very short oblique carina on each side of the base, 

 and the dorsal margin with a crenelated carina from the shoulder 

 meeting the posterior carina at the declivity ; the upper surface is 

 thus divided into three deeply depressed areas of approximately 

 equal width, bearing irregular rows of shallow punctures. Legs 

 black, bare, sparsely setose beneath ; internal angle of tibiae with a 

 short spur, outer angle not produced; tarsi moderately long and stout.

The nearest ally of this little species is B. fiexicosus, Mshl., from 

 which it may be at once distinguished by its tuberculated thorax. 

 The structure of the elytra is very similar, but in fiexuosus the
