the head and thorax, slender, ahnost filiform, arcuated, slightly dilated 

 over the origin of the antennte, piceous, minutely and remotelj^ punctured. 

 Antennae inserted behind the middle of the rostrum, piceous, club rufous ; 

 third joint (second of the funiculus), two-thirds the length of the preced- 

 ing, and twice the length of the following joint, Thorax in the middle, 

 longitudinally elevated, or almost carinated, covered with linear-lanceo- 

 late scales, which converge from the sides towards the central carina. Ely- 

 tra with acute, remotely punctured stria;, and flat interstitial lines, each one 

 of which is covered with large superticial confluent punctures, and three or 

 four series of linear-lanceolate scales ; an oblique elevation or callus before 

 tlie tip of each elytron. Body beneath more densely covered with whiter, 

 shorter oval scales. Breast, before the anterior legs, widely indented, not 

 canaliculate, unarmed.

 crebre punctulatum, nigrum, squamulis tenuioribus, cinereo-albidis undique

 femoribus clavatis, anticis obsolete dentatis, posterioribus muticis, tibiis

The reference to this genus seems to me doubtful, especially as the 

 species is immediately followed bj'' B. constrictus, which has no resemb- 

 lance to Balaninus, but is an Erirliinine (p. 168). It is quite possible, that 

 this insect, on renewed study of the type in Stockholm, may prove the 

 same as my Dcsmoris seapalis, which is congeneric with D. constrictus.
