250 CLAVICORNIA. [Mc'lil/cfheS. 



tremity of the last segment of the abdomen, which is wanting in 31. 

 dilfjcilis. L. U-2i mm. 



Oa Laliatce, especially Lamium album and S/acJit/x sylvafica ; rather widely dis- 

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

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

 l.iud. 



SS. viduatus, Sturm {melcmarius, Forst.). Eather 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 ; puljescence Ijlackish ; antennas 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 tibiae somewhat obliquely cut off to wards apex, 

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

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

 mm. 



On Lahiatce, especially Salvia praiens/s, Galeopsis tetrahit, and Mentha aqiiaiica 

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

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

 (Chappull) ; INIauchester district; it occurs commouly in Laugwortli Wood near 

 Lincoln, on AJuga repfans, aud by general sweeping, and I have also taken it on 

 strawberry flowers in my garden at Liacolu ; Scotland, Solway district, Thoruhill, not 

 uncommon. 



3SI. pedlcularius, Gyll. (tenebrosus, Forst.). Yery 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 tibia3 rounded on the outside, and not obliquely cut off as in M. 

 vi hiatus, and the larger teeth at the apex of the anterior tibiae are 

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

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

 shining space. L. 2-2j mm. 



On Labiates, especially Lamium album and Salria prafensis ; local ; Loudon district, 

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

 Forest; Wicken Fen ; Glanvilles Wootton ; Exmouth ; Da\\lis.h; IJcwdley ; Lincoln 

 (common on AJuga rcptans and strawbfrry llowers) ; Northumberland district, very 

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



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

 conclusion that, except on the male character^ 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. 2)edicu!anus and viduatus are hardly different ;" 

 the relative punctuation, size of teeth of anterior tibia3, &c., are quite 

 useless characters, as they are very variable in different sj^ecimens, 



"SH. bidens, Bris. Rather like M. pedlcularius, but smaller than
