170 RHYNCHOPHOHA. [AplOU. 



short broad stria, has a fine stria or furrow before scutellum, which is 

 usually continued beyond middle ; the punctures of the interstices of the 

 elytra are also placed more closely together. L. 2^-3^ mm. 



On Rumex hydrolapathum (the great water dock) anil also on R. obtusifolius (the 

 broad dock); widely distributed throughout the greater part of England and Wales 

 and not uncommon in many localities, but much less common than A. violaceum ; it 

 >s widely spread throughout the midland counties, and general in the Manchester 

 district; it has not, however, been recorded from the Northumberland and Durham 

 district; Scotland, Solway and Forth districts; Ireland, Dublin, lielfast, &c , and 

 probably general ; it has been taken at Swansea on lucerne. 



A. humile, Germ, (curtirosfre, Germ., brevirostre, Gyll., plebdum, 

 Stcph.). Black, rather dull, clothed with fine and distinct greyish 

 pubescence; head broad, almost quadrate, very closely punctured and 

 very finely rugose between eyes, which are slightly prominent; rostrum 

 short and stout, dull and thickly punctured at base, more shining towards 

 apex ; antennie rather stout, inserted about middle of rostrum ; thorax 

 subcylindrical, about as long as, or a little longer than, broad, with close 

 and deep punctuation and a small fovea at base ; scutellurn rather long ; 

 elytra sometimes with an extremely slight metallic reflection, widened 

 behind, broadest behind middle, with the shoulders obliquely rounded 

 and not strongly marked, and with plainly punctured striae, interstices 

 about as broad as the striaB, shagreened ; legs black, rather slender and 

 not elongate. L. l|-2j mm. 



Male with the rostrum thicker than in female, and the thorax shorter. 



On Sumex acelosa (the sorrel dock) and amongst grass and herbage; the larva 

 lives in the stems of the food plant; common and generally distributed throughout 

 .England and probably Scotland and Ireland. 



SUB-FAM. Brachyrrhininae. 

 (Otiorrhynckidce and Srachyderidce.) 



This sub-family contains several important tribes, which are largely 

 represented in the European fauna ; they comprise all those genera in 

 which the mandibles are provided externally at apex with a corneous 

 appendage, or with the cicatrix of such appendage; these appendages are 

 always present in the pupa state, but are deciduous and are almost always 

 shed as soon as the perfect state is attained; they may, however, be 

 occasionally observed, and I have a fully developed specimen of the rare 

 Givnopsis fissirostris in my collection in which they are very perfect and 

 are about as long as the rostrum : in one or two specimens also of 

 Otiorrliynclms tenebricosus in my possession, one appendage remains, but 

 in this species these false mandibles appear to be much shorter propor- 

 tionally and less falcate than in Ccenopsis ; Leconte and Horn (Classifi- 

 cation of the Coleoptera of North America, p. 434) notice this variation 

 and state that the deciduous pieces are of varying form, usually elongate 

 and slender, sometimes falcate and acute, or short and conical ; as they
