12G Capt. T. Brouii on new 



lihue slpiifler at base, expanded Ijeyond, minutely denticulate 

 externally, the two front pairs obliquely truncate at the 

 cxtrenaity, the posterior obliquely ronnded. Tarsi filiform 

 and slender, not as long as the tibite, the basal three joints 

 elongate and nearly equal, third not lobate, and interposed 

 between it and the elongate terminal joint there is a minute 

 but distinct fourth joint. 



Front coxa large, prominent, almost contiguous, the inter- 

 mediate and posterior just perceptibly separated. Abdomen 

 rather longer than the metasternum, its segments with 

 straight sutures, that between the basal two very fine, the 

 others deep; the segments are horizontal and on the same 

 plane, the first is distinctly longer than the second, the 

 third and fourth are nearly equal to one another, but shorter 

 than the preceding one. 



In Scolytus the general form may be termed stumpy, the 

 anterior tibiae terminate in prominent curvate hooks exter- 

 nally, the elytra are quite truncate at the apex, and the 

 abdomen is retracted and suddenly bent upwards, so that 

 the metasternum is abruptly prominent. In the genus here 

 described the tibiae are unarmed at the outer extremity, the 

 ventral segments are horizontal and are contiguous v^itli the 

 epipleurse throughout. Tomicus more nearly resembles this 

 genus in contour, but the eyes are emarginate and the poste- 

 rior portions of the elytra are either truncate or excavate 

 and spinose. 



Mesoscohjtus inurbanus, Broun. 



Cylindrical, slightly nitid, rufo-piceous or nigrescent, 

 sparingly clothed with erect, slender, yellowish hairs ; legs 

 and antennae testaceous or pale castaneous. 



Thorax longer than broad, base truncate, its rounded 

 anterior portion transversely punctate-rugose or granulate, 

 its appearance depending upon the direction from which it is 

 examined ; the basal part is finely and distantly sculptured 

 and the middle of the disk is somewhat elevated. Elytra 

 M'ith three or four ill-defined stiise near the apices, but 

 on the dorsum with series of moderately fine punctures, 

 interstices simple. Scuiellum smooth. The anlennal club, 

 though palette-like above, is feebly articulated underneath, 

 the bald basal joint being as 1; ng as the three pubescent 

 terminal ones. 



Underside shining, brownish black, sparingly clothed with 

 elongate but extremely slender greyish hairs. Flanks of 

 prostcrnum finely punctured. Metasternum convex, almost
