16 Mr. F. P. Pascoe on some new or little-'known 



Mentum transversum, siibintegrum. Palpi articulo ultimo ovato. Pro- 

 thorax subquadratus, lateribus denticiilatis. Tarsi siibdilatati, articulo 

 primo majore. Corpus sublatum^ planatum. 



Allied to Cucujus and Platisus. The first it strongly resembles in 

 habit, but diifers in the normal condition of the tarsi, the ovate 

 terminal joint of the palpi, the head not prolonged behind the eyes, 

 the mentum nearly entire anteriorly, and the hroa /, rounded lobes 

 of its deeply divided labium. From Platisus it differs in its robust 

 habit, thicker antennae, the third joint of which scarcely exceeds 

 the first in length, the narrower tarsi, not dilated at the sides, and 

 the denticulate margins of the prothorax.

obsolete bicostatis. 

 JIab. New South Wales. 



Pitchy black, subnitid, especially the head and prothorax, finely and 

 very closely punctured; head broadly obcordate, a deep transverse 

 gi'oove behind the eyes, the clypeus descending between the man- 

 dibles and hiding the lip ; antennae rather longer than the breadth of 

 the prothorax, moniliform, the basal joint short, incrassated, the second 

 short, the third scarcely longer than the first, the remainder shorter 

 and subequal, the last ovate, pointed ; eyes moderate, roimded ; max- 

 illary palpi with the terminal joint oblong-ovate, of the labial shortly 

 ovate; maxillary lobes shortly ciliated at the extremity; mentum 

 transverse, not produced anteriorly (the large transverse piece beneath 

 this in the figm-e is the jugular plate) ; labium bilobed, the lobes broad, 

 rounded ; prothorax subquadrate, broader than long, rounded at the 

 side, with four or five minute, distant teeth, the disk near the anterior 

 angles slightly hollowed out ; scutellum transverse, rounded behind ; 

 elytra plane, strongly bent doT\Ti at the sides, each having on its disk 

 two nearly obsolete elevated lines in addition to the more strongly 

 elevated line of the suture; body beneath and legs reddish pitchy, 

 closely punctured. Length 7 lines. 



Syngemis [Cucnjidae]. 



Captit oblongo-subquadratum. Ociili prominuli, prothorace distantes. 

 Antennce breves, subclavatse, articulo basali ovato incrassato. Maxillce 

 lobo interiore uncinate. Tarsi articulis tribus primis dilatatis, penul- 

 timo minuto. Corpus elongatum, parallelum, planatum. 



A remarkably elongate and narrow form belonging to the sub- 

 family Sylvanince as at present constituted, strongly illustrating the 

 impropriety of separating Sylvanus from the Cucujidai, as has been 

 done by M. Jacquelin du Yal, and of the danger of coming to con-
