250 CLAVICORNIA. [Mdiyttlies. 



treniity of the last segment of the abdomen, which is wanting in M. 



L. lf-2^ mm. 



Ou Labiates, especially Lamium album and Slachys sylvatica ; rather widely dis- 

 tributed and not uncommon in the London and Southern districts; rarer further north ; 

 Tewkesbury ; Liverpool; Northumberland district, rare; not recorded from Scot- 

 l.md. 



ltt. viduatus, Sturm (melanarius, Forst.). Rather broad oval, with 

 close and comparatively fine punctuation, which gives the insect a rather 

 dull appearance as compared with the five preceding species ; black, 

 moderately shining; pubescence blackish; antennae dark brown with 

 the first two joints red ; thorax punctured much as elytra, somewhat 

 narrowed in front, with the side border slightly raised ; hinder pairs of 

 legs dark brown, with the tibite somewhat obliquely cut off towards apex, 

 front legs lighter ; anterior tibiae with two or three conspicuously stronger 

 teeth at apex ; male with the last abdominal segment simple. L. 2-2^ 

 mm. 



On Labiates, especially Salvia pratensis, Galeopsis tetraliit, and Mentha aquafica 

 (according to Brisout) ; local and usually considered rare; Caterham ; Wicken Feu ; 

 Mablethorpe, Lincolnshire ; Chat Moss (on Galeopsis tetrahit, var. versicolor 

 (Chappell) ; Manchester district ; it occurs commonly in Laugworth Wood near 

 Lincoln, on Ajuga reptans, and by general sweeping, and I have also taken it on 

 strawberry flowers in my garden at Lincoln ; Scotland, Solway district, Thornhill, not 

 uncommon. 



M. pedicularius, Gyll. (tenebrosus, Forst.). Very like the preced- 

 ing, but less convex, of somewhat larger and blunter form, with finer 

 punctuation ; the thorax has somewhat more parallel sides, and the side 

 border is very slightly raised ; the hinder pair of legs are said to have 

 the tibiae rounded on the outside, and not obliquely cut off as in M. 

 vi luatus, and the larger teeth at the apex of the anterior tibiae .ire 

 weaker. The male has a large smooth tubercle at the extremity of the 

 last abdominal segment, behind which there is an inclined, smooth, 

 shining space. L. 2-2j mm. 



On Labiatce, especially Lamium album and Salvia pratensis ; local ; London district, 

 not uncommon, Darenth Wood, Chatham, Caterham, Micklebatn, Dorking ; New 

 Forest; Wicken Fen ; Glanvilles Wootton ; Exmouth ; Dawlish ; Hewdley ; Lincoln 

 (common on Ajuffa reptans and strawberry flowers) ; Northumberland district, very 

 rare ; not recorded from Scotland ; Ireland, near Waterford. 



I have very carefully studied these two species, and have come to the 

 conclusion that, except on the male characters, it is impossible to separate 

 them ; the male characters themselves are not always constant, so that 

 it is quite possible that they may be identical ; Reitter, in a letter to me 

 on the subject, says " M. pedicularius and viduatus are hardly different ;" 

 the relative punctuation, size of teeth of anterior tibia3, <fec., are quite 

 useless characters, as they are very variable in different specimens. 



UK. bidens, Bris. Rather like M. pedicularius, but smaller than
