254: CLA.VICORNIA. [MeligetJies. 



deep black, shining, with scanty pubescence ; antennge, as a rule, reddish 

 or reddish-yellow, but sometimes darker ; thorax longer than in any 

 other of our species, almost as long as broad ; punctuation rather strong, 

 especially of elytra ; legs varying in colour from yellowish to dark 

 brown ; anterior tibiae strongly dilated for at least two-thirds from apex, 

 and furnished with strong irregular teeth, of which four or five at base, 

 apex, and in the middle, are especially conspicuous. L. l|-2 mm. 



On Marrubkim vulgare. Erysimum aUlaria, and Salix aurita ; very rare in 

 Biitain ; Putney, one specimen with dark legs and autennaj (Rye) ; Horsell, one 

 specimen with light legs and autennaj (Power); Mickleham. 



This species is allied to M. serripes, but may be distinguished from it 

 by its much longer thorax, stronger and less close punctuation, and also 

 by the stronger and more irregular denticulation of the anterior tibia;, 

 which are more dilated than in M. serripes. 



ItK. serripeS; Gyll. {qnadridens, Fijrst.). Oblong-oval, rather flat, 

 shining black, occasionally with a leaden reflection, which is chiefly 

 seen in fresh specimens, and is caused by the fine ashy-grey pubescence 

 with which the insect is clothed ; antenuiB and legs pitchy or reddish- 

 brown ; thorax half as broad again as long, about as broad behind as 

 elytra, rather plainly sinuate at base ; punctuation distinct, about the 

 same on thorax as elytra ; anterior tibiae armed with a row of short, 

 strong, sharp teeth from a little below base to apex ; these are usually 

 regular and even, but occasionally are variable, and sometimes abnormal 

 specimens occur with six or seven teeth on one side and three or four 

 larger ones on the other ; metasternum of male with a distinct channel 

 behind. L. 1^-1 f mm. 



On EcJ/ium vulgare, Salvia pratensis, Saponaria officinalis, &c. ; not common ; 

 Darenth Wood, Faversliam, Mickleham, Esher, Caterham, Dorking, Shiere, Hamp- 

 stead, Chaldon (Surrey) ; Brandon, Suffolk ; Eastbourne ; Glanvilles Wootton ; 

 Ci'omer, Norfolk ; Holy Island, 



This is rather a variable species, and may sometimes be confused with 

 small rubbed examples of M. JIavijjes or M. jncipes ; it may, however, 

 be distinguished from both by its narrower form, and the invariably 

 stronccer denticulation of its anterior tibite. 



Tfl. murinus, Er. (seniculus, Er., ? ). Oblong, not very convex, 

 black, clothed with thick greyish or whitish pubescence; antenna3 

 black, with the second joint, nnd sometimes the next one or two, reddish- 

 brown ; thorax one-third broader than long, rather thickly and finely 

 punctured ; elytra rather less thickly punctured than thorax ; cross 

 striation between punctures only present on scutellum ; legs black, with 

 tarsi somewhat lighter; anterior tibiae armed with a row of regular 

 comb-like teeth from a little below base to apex ; male with the last 

 abdominal segment furnished with a very small and narrow triangular 

 indentation. L. r|-2^ mm. 



On Cynoglossum and Echium vulgare; locally abundant, crpecially on and near 

 the coast in the south-eastern and southern districts; it is, however, rarer further
