60 OTIORHYXCHID^. fHorn. 



Hind tibife with two sliort, fixed, terminal 

 spurs, first suture of abdomen feebly 

 arcuate. Front slightly transversely im- 

 pressed SCIOPITHES. 



Hind tibiae without terminal spurs, first 

 suture strongly arcuate at middle. Front 



not impressed AGRONUS. 



Metasternal side pieces moderately wide, su- 

 ture distinct. 



Hind tibiae without terminal spurs ; first 

 suture of abdomen strongly arcuate at 



middle NEOPTOCHUS. 



The fixed spurs of the hind tibiix? appear not to have been noticed by anj'- 

 author; they are in fact, difficult to see -in some species, while in others, 

 quite large and prominent (0. maurus). I am not at present aware of the 

 occurrence outside of the tribe Otiorhynchini of any similar structure. 

 Thecesternus has the tibiae bimucronate. The female of Ithycerus presents 

 curious characters. On each tibia in addition to the usual mucro are two 

 spurs, one ot which at least is moveable. The male has the tibiae simply 

 mucronate.

Rostrum as long as the head, moderately robust, more or less dilated at 

 tip which is notched at middle. Antennae anterior long ; scape long, very 

 slightly arcuate not longer than the funicle and club, attaining the thorax ; 

 funicle Tjointed, first two joints longer, joints 3-7 obconical. Scrobes supe- 

 rior deep, sides strongly divaricate beliind. Eyes rounded or slightly oval. 

 Thorax oval, longer than wide. Elytra variable, broadly or elongate oval. 

 Scutellum very small or indistinct. Legs moderately long, thighs clavate, 

 tibiffi feebly arcuate near the tip. Cotyloid cavities of hind tibiae terminal. 

 Tarsi moderately dilated, spongy pubescent beneath, third joint deeply 

 bilobed. Second abdominal segment not as long as the two following united, 

 separated from the first by an arcuate suture. 



This genus contains in our fiiuna species which have been introduced 

 from Europe, and which have established themselves in the north-eastern 

 parts of our territory. Two are found in Greenland, which also occur in 

 the extreme north of Europe, their distribution being due to natural laws 

 and not through the agency of commerce. 



The species are known as follows: 

 Femora toothed. 



Tooth very small.' Rostrum sulcate, at tip with a 



bifid carina, elytra sulcate sulcatus. 



Tooth large, rostrum not sulcate, tip not carinate, 



elytra not sulcate ligneus. 



Femora not toothed.
