tliis character gives it an affinity to tlie Bolitocharina, and separates it 

 ironi Gipimusa and Deiwqisis, with which it is usually closely associated. 



nx. dulila, Grav. (conuroides, Malth., ? valida, Muls. et Eey). 

 Fuscous hlack, clothed with a fuscous pubescence, rather coarsely tuber- 

 culate, widest at the apex of elytra ; antenniE long and slender ; head 

 acutely attenuated in front, mouth yellow ; thorax widest at base ; elytra 

 as long and rather wider than the thorax ; hind body as long as head, 

 thorax, and elytra, acutely narrowed and attenuated towards the ajiex, 

 penultimate segment edged with white, apical segment pale ; legs and 

 antennoe pit(;hy-testaceous. L. 3-3 .^ mm. 



Marshy places, in moss, flood refuse, &c. ; Lee, Cobli.im, S(roo(1, Ainberlej", Norwood, 

 Toiibridire, Higliam, Mertou (Suripy). Tilgate ; Oxfordsliiie ; Cliat Moss ; Colesliill, 

 near B riniugham ; Northumberland district; Scotland, local, Sohvay, Tweed, Forth, 

 and Tay districts. 



This species differs from the rest of the genus in its larger size, much 

 broader thorax and elytra, and in the much greater dilatation of the base 

 gf the thorax. 



Tft. intermedia, Er. {attenuata, Matth.). This species much 



resembles the preceding, but is distinctly smaller and narrower ; the base 



of the thorax is less dilated, and the apex of the hind body is more 



broadly pale ; the sculpture also is finer ; according to Mulsant and Eey 



the elytra are more deeply emarginate at postero-exteinal angles than in 



M. duhia, but in named specimens sent me by Mr. ]\Iatthews they appear 



to present a less emarginate appearance than in the latter species. 



L. 2-2i mm. 



Marshy places; common and generally distributed in the South and the Midland 

 districts ; not recorded irom the North of England, but probably occurs in many places ; 

 ^cotlan(l, local, Solway and Tay districts. 



Mr. Matthews remarks that this is perhaps the most common species 

 of the genus. 



TSL. minuta, Grav. (inmuta, Matth.). Fuscous black, clothed with 

 short grey pubescence, finely and closely tuberculate, head much produced 

 and attenuated in front ; mouth yellow ; thorax slightly dilated at the 

 base; elytra not longer, but rather wider than the thorax, hind body shorter 

 than head, thorax, and elytra together, obtusely attenuated, apical and 

 greater part of the penultimate segments rufo-testaceous; legs and antenuiB 

 testaceous. L. 1|-1| nim. 



In marshy places, sphagnum, &c. ; rare ; most of the specimens recorded ns this 

 species belong to M. infascata ; it is recorded as not uncommon in the London district, 

 and coinnion in the southern parts of Scotland, but probably most of the specimens 

 niu-t be reftried in both cases to the last-mentioned insect, which is exceedingly hard 

 to distinguish from M. minuta, except by a careiul comparison ; the true M. minuta 

 has occurred in Oxfordshire, and one or two other localities. 



M. minuta differs from the first two species in its minute size, longer 

 thorax, and shorter and stouter antenna?; from M. Masojii it may be known 

 by its liroader auii longer thorax and elytra, and by its more depressed
