COSSONIDAE. 585 



small, widely distant above. Thorax rather longer than broad, the deep 

 frontal constriction at each, side connected above by a fine apparently raised 

 line ; the basal portion oviform, not longer than broad, flat, densely and 

 minutely sculptured, its punctation moderately distinct, rather distant and 

 irregular. Scutellum small. Elytra twice the length of thorax, a little 

 broader than it is at the base, slightly arcuate-emarginate there, their sides 

 straight as far as the posterior declivity ; dorsum nearly flat, finely rugose, 

 closely striate-punctate. 



Scape medially inserted, only moderately flexuous ; second joint of 

 funiculus rather longer than the basal, third and fourth slightly longer than 

 fifth. ; club normal. 



Underside piceo-rufous, slightly nitid, rather distantly and moderately 

 coarsely punctured, with fine grey setae, basal ventral segments medially 

 flat. 



Fern. — 2f mm. by quite \ mm., slightly shining, elytra light chestnut- 

 red ; rostrum rather longer and more slender, finely punctate, slightly 

 dilated at the antennal insertion, behind the middle ; without any trans- 

 verse raised line between the thoracic constrictions. 



The male of this small species may be identified by the distinct incurva- 

 ture of the sides of the rostrum behind the middle, and the raised line 

 across the constricted portion of the thorax. The female specimen may not 

 really belong to this species.

4143. Eucossonus oreobius sp. nov. 



Elongate, subdepressed, subopaque ; fusco-rufous, the sides of elytra, 

 the tibiae, tarsi, and antennae light chestnut-red ; irregularly clothed with 

 elongate, mostly decumbent, yellow setae. 



Rostrum stout, fully a third shorter than thorax, a little narrowed 

 behind, opaque, finely punctate. Thorax a third longer than broad, evidently 

 constricted in front ; glabrous and only slightly impressed along the middle, 

 densely and minutely sculptured, distinctly and moderately coarsely punc- 

 tured. Scutellum distinct. Elytra double the length of thorax, rather 

 broader than it is at the base, slightly biarcuate there ; minutely sculptured 

 and rugose, distinctly but not coarsely striate-punctate, quite striate near 

 the extremity. 



Scape flexuous, implanted at or just before the middle ; second joint 

 of funiculus as long as the first, third and fourth slightly longer than 

 broad ; club normal. 



Underside slightly nitid, piceous, prosternum and last three ventral 

 segments more rufescent ; moderately closely and coarsely punctured, the 

 intervals more or less minutely sculptured, with some fine grey setae ; 

 metasternum with a linear impression along the middle behind ; basal two 

 segments with a shallow median impression, the suture between them 

 indistinct. 



Fern. — Rostrum rufous, somewhat nitid, finely and moderately closely 

 punctate, not smooth along the middle, rather more dilated at the antennal 

 insertion, behind the middle, than in the same sex of E. eleqans (2419). 



The female of E. oreobius is imdoubtedly nearly allied to the type of 

 2419 — also a female — which was found at a low level on the eastern seashore ; 

 in habit, therefore, these species differ considerably.
