Cueujus muticus. Fab., appears to agree with the preceding in the 

 formation of its essential organs, although the sides of the thorax are not 

 denticulated. In another small British species, (Tab. Supp. XLVH. fig. 1.), 

 nearly allied to the Cue. dermestoides, (which Mr. Stephens has named in 

 his Catalogue, Cue. testaceus, Pk., Fab., and Gyll., but which appears 

 to me rather to be the Cue. piceus, Oliv. and Latr. Hist. Nat. 11, 256, 4.) 

 the antenna are formed as in Cue. dermestoides, the labrum is, however, 

 much larger than in that species, and semicircular (Ibid. fig. 1, A.), and 

 the terminal joint of all the palpi is but very slightly truncate, being al- 

 most acute (Ibid. C. and D.), the labium is entire (D.) This species 

 (which I received from Mr. Ingpen, who procured it from the decayed 

 part of an old elm-tree, in Wiltshire, in the month of December,) al- 

 though agreeing with Gyllenhal's description of the form of the head, 

 antennae, and form and striation of the elytra of Cue. testaceus, appears 

 to be too darkly coloured for the description of that species, being 

 rufo-eastaneous rather than rufo-testaceous, and Gyllenhal says of the 

 thorax of Cue. testaceus, " sub-quadratus — angulis posticis parum pro- 

 " minulis," whereas in my insect, the sides of the thorax are slightly 

 denticulated at the base, although agreeing in other respects with Gyllen- 

 hal's description. 



In the breadth of its body and in its more developed labrum, the Cucu^ 

 jus monilis. Fab., Pk., and Gyll., {Cue. hipustulatus, Hellw., Latr., Pz., 

 Cue. bimaeulatus, Oliv., Latr.,) appears to recede from the typical form of 

 the genus. In the specimens which I have seen of this insect, the antenna 

 have the last three joints thickened ; they therefore appear to be the var. a. 

 of this species, described by Gyllenhal ; but I very much question whe- 

 ther they are, as he supposes, males, since, notwithstanding its greater 

 size, I should be induced to regard his var. b, " antennis filiformibus, di- 

 " midio corpore longioribus — articulis ultimis non crassioribus, sed elon- 

 " gatis cylindricis," as the male of the species. 



In the Exotic Cabinet of the British Museum, are several specimens of 

 a small pale testaceous species, with the thorax subquadrate, named by 

 Dr. Leach, " Cueujus monilis, H. testaeeus, Pk." This is a British spe*
