COSSONIDAE. 24:9' 



Rostrum broatl and paiallcl for half its length in front, distinctly 

 narrowed behind, very slightly arched; closely and moderately coarsely 

 punctured, lather more finely and distantly in front, distinctly de- 

 pressed along tlie middle, hardly more than half the length of the 

 tho)-ax. Head nariowed anteriorly to the same width as the base of 

 the rostrum, similarly sculptured to behiml tlie eyes, the occiput not 

 quite smooth. Eyes not prominent. Thorax a third longer than broad, 

 widest beliind the middle, very gradually narrowed anteriorly, a little 

 constricted near the apex ; usually broadly impressed or flattened along 

 tlie middle, where the punctation, though moderately coarse, is not as 

 close as it is near the front and sides, the middle of the apex is almost 

 smooth. Scutellum small but distinct. Elytra truncate at the base and 

 scarcely wider than the thorax there, twice its length, their sides almost 

 quite straight, very gradually narrowed posteriorly, witli simple apices; 

 they are plane, distinctly and closely seriate-punctate; interstices with 

 minute serial punctures and, in some aspects, appearing rugose. 



Legs moderately stout; anterior tibiae flexuous, distinctly uncinate, 

 and acutely angulate at the inner extremity; tarsi slender, penultimate 

 joints slightly dilated, deeply excavate above and subbilobed. 



Scape gradually incrassate, inserted before the middle; 2nd joint 

 of the funicle not quite as long as the basal and more slender, the next 

 not ([uite as long, 4tli and 5th rather shorter and l)rnader; club ol)long- 

 oval, with small apical articulations, pubescent. 



Underside shining, rufo-castaneous, finely pubescent, moderately 

 coarsely and closely j^unctured, the last three segments rather more 

 finely; basal ventral segment a little longer than the 2nd, broadly 

 depressed along tlie middle, its apical suture straight but fine, these 

 segments together are ratlier longer than the metasternum. 



Fem.—lje'iH robust, the rostrum more slender, distinctly narrowed 

 behind, and more finely sculptured. Scape medially inserted. 



Rather more robust than the other members of the genus. It most 

 nearly resembles the male of li. elongatus, 2980, but is evidently broader, 

 and lias the rostrum almost canaliculate.

Bell Hock, near Methven. Six males and two females found amongst

 whose name has been given to it. 



3653. Rhinanisus fusiformis sp. nov. 



Fusiform, nitid; tlie rostrum, thorax, and legs piceous, elytra 

 castaneous, antennae and tarsi pale ferruginous; pul)eseenee scanty, 

 suberect, short, slender, and greyish. 



Rostrum half the length of the thorax, siibparallel, broad and slightly 

 arched in front, evidently contracted towards the eyes; finely and dis- 

 tantly punctured on the middle in front, rather closely, coarsely, and 

 somewhat rugosely behind, and as far as tlie back of the eyes. Head 

 gradually nai-rowed to the width of the rostrum, the occiput with a 

 few fine jDunctures. Eyes nearly flat, lateral, subrotundate. Thorax 

 moderately rounded and widest (piite behind the middle, gradually 

 narrowed anteriorly, slightly consti'icted in front; the disc only slightly 

 flattened, moderately coarsely but not closely punctate, smooth at the 

 'ap?x; curvedly narrowed near the base. Scutellum small l)iit distinct. 

 Elytia feebly arcuate at the base and just a little broader than the 

 thorax tlu're. gently narrowed bcliiiid, with, individiinlly, slightlv
