2GG [May, 



hrosus, with very slightly stronger punctuation and weaker pubescence, and with 

 the posterior margin of the thorax not broader than the base of elytra ; the thorax 

 is narrower, with its sides more parallel ; the teeth of the anterior tibiae are rather 

 stronger ; the metasternum is impressed, and has two small tubercles on the front 

 edge of the impression, and the last segment of the abdomen is furnished with a 

 small smooth tubercle. Length, Ij lin. 



Common in France on Salvia and Mentha?) 



h. Thorax at base at most as wide as elytra ; anterior tibiae with 

 three or four conspicuously larger teeth at apex, the last 

 but one being usually the largest. 



Of. Punctuation closer and weaker ; upper surface dull. 



M. incanus, Sturm. — About the size of M. umbrosus, of exactly oval outline 

 (the shape is well figured by Sturm, Deutschlands Insecten., xvi, plate cccix, F) , 

 thickly and very finely punctured, with fine cross striation between punctures, and 

 clothed with fine greyish-brown pubescence ; antennae black or brownish, with the 

 first two joints lighter ; anterior tibiae dilated towards apex, with three or four 

 rather strong irregular teeth near apex, of which the last but one is usually the most 

 prominent. Length, li lin. 



This species comes near M. ovatus, but is more closely punctured, 

 and comparatively dull ; a single specimen only is known as British, 

 which was taken by Mr. Gr. R. Waterhouse, in Darenth Wood, in 

 July, 1859, on Echium vulgare : this specimen Mr. C. O. Waterhouse 

 has kindly sent me for examination ; it is a small example of the 

 species, but otherwise agrees exactly with the description of M. in- 

 canus, and with a type sent me by Herr Eeitter ; it is quite distinct 

 from all our other species. M. Brisout has taken this insect on 

 Solaniwi dulcainara and Nepeta cataria. 



8. Punctuation stronger ; upper surface shining. 



M. ovatiis, Sturm. — Black, shining, oval, convex ; something like M. viduatus, 

 but more ovate, with the thorax more narrowed behind ; antennae black, with the 

 first three joints red ; punctuation much stronger than in either of the three pre- 

 ceding species ; anterior tibiae strongly dilated with three or four large teeth at 

 apex, which are very variable. Male with a strong tubercle at the extremity of the 

 last segment of the abdomen, and with the anterior tarsi conspicuously dilated. 

 According to M. Brisout, this species may easily be distinguished from its allies by 

 the form of the extremity of the elytra, the posterior margin of each being slightly 

 sinuate, with the sutural angle a little prolonged and rounded.
