246 CLAVICORNIA. [Mdigetlws. 



rather darker; anterior tibiro with very fine, almost imperceptible, teeth, 

 which are slightly stronger at apex. L. 2-2 mm. 



Inuiarsby places on Vmbellifera, Genitce, and Crucifera ; not common ; Dan nth 

 Wood, Dageuham, Strood, Southend ; Hastings; North Devon ; Bannouth ; Askham 

 Bog; not recorded from the extreme northern counties of England or from Scot- 

 la nJ. 



The very plain cross reticulation between the punctures is a valuable 

 character for this species ; rubbed examples, at first sight, resemble 

 M.picipea, but the longer shape and the very finely toothed anterior tibiae 

 will at once distinguish them. 



IH. subrug-osus, Gyll. A small species, ovate, rather convex, 

 shining black ; antennae entirely black ; head and thorax thickly and 

 finely punctured, the latter about a third broader than long, elytra 

 rugosely punctured, with strong transverse striation, especially towards 

 base ; the front tibise are very finely crenulate, as in M. corvinus, and 

 are rather lighter than the rest, but all the legs are more or less pitchy- 

 black or pitchy-brown. L. If mm. 



Only one British specimen of this species is known ; this was taken by Dr. Sharp 

 ninny years ago on the banks of the Water of Ken, Galloway, Solway district ; the 

 insect occurs in many parts of Europe, not uncommonly in some localities ; in Gt-nnany 

 it is widely distributed, but rare ; it will probably Le found in Britain in some 

 numbers. 



The peculiar rogose and wavy sculpture, which is nearest to, but 

 quite distinct from, the sculpture of M. rufipes, is the chief characteristic 

 of this remarkable insect, which in some points resembles at first sight 

 M. serripes. M. siilstngosus, Er., is a variety of this species of not quite 

 so deep black a colour, less convex, with finer cross striation, and with 

 lighter legs and antennaB, according to Erichson ; Brisout, however, 

 says that they are darker than the type form. 



UK. coracinus, Sturm. Oblong-oval, black, rather dull, occasionally 

 with a very slight greenish or bronze reflection; punctuation of elyt'. a 

 and thorax close and fine, with very fine cross reticulation between 

 punctures ; antennae black witli the two first joints reddish-brown ; 

 thorax rather variable in shape in the sexes ; legs pitchy, anterior 

 tibise rather lighter, very finely denticulate, rather more distinctly to- 

 wards apex ; intermediate and posterior tibire straight or almost straight 

 for two-thirds from base, and from thence sharply and obliquely cut 

 off to apex. L. 2 mm. 



Not rare on the Continent, according to Brisoufc, on flowers of Galium and Prunus 

 spinosa ; very rare in Britain ; Hampstcad (Waterhouse) ; Darenth Wood (Rye) ; Mr. 

 Blatch records it from Wicken Fen, Hunstanton, and Weymouth, in horned poppy 

 and other flowers ; dark examples of M. eenexs are often placed under this name in 

 collections, and I have had several sent to me as this species ; mistakes seem to arise 

 from the fact that M. coracinus is said to have a greenish reflection ; it is, however, 

 us a rule, so very slight, that for all practical purposes the insect may be considered 

 as black.
