1883.] M. JACOBY ON NEW SPECIKS OF BEETLES. 401 



3. OiDES CLARKir, sp. nov. (Plate XLV. fig. 3.) 

 Oblong-ovate, testaceous ; anteuiise piceous ; elytra closely punc- 

 tured, the suture and a longitudinal band, divided at the middle, from 

 the base to the apex black. 



Length 3| lines. 



Uab. New Guinea, Waigioii, 



Head with a central impressed groove and a deep transverse de- 

 pression between the eyes ; labrum testaceous, punctured ; apex of 

 jaws black. Antennoe elongate, the third and fourth joints nearly of 

 equal length. Thorax narrowly transverse, the anterior and posterior 

 margins parallel, the sides slightly rounded ; surl'ace transversely 

 depressed in front of the anterior margin, and with a round shallow 

 fovea at each side, obsoletely and finely punctured. Scutellum 

 obscure piceous. Elytra widened towards the middle, the sides 

 sliglitly constricted below the base; the surface covered with fine 

 but distinct punctures, testaceous ; a narrow sutural and a broad 

 lateral band from the base to the apex, both bands joined at the 

 latter place, black ; the lateral band is divided longitudinally in the 

 middle b)' a narrow space of the ground-colour. Uuderside and legs 

 testaceous ; tibia and tarsi slightly darker. 



Collected by Mr. Wallace. 



Allied to O. fnji and O. seminiyrum, Clark, but distinguished 

 from both by the sutural baud. In one specimen before me the 

 lateral elytral band is entire and not divided at the middle, but ia 

 other respects the specimen agrees with the type. 



4. OlDES BIPLAGIATA, sp. uov. (Plate XLV. fig. 2.) 

 Broadly ovate, flavous ; thorax and elytra very finely punctured, 



the latter with a transverse band at the middle and a large oval spot 

 at the apex black. 



Length 4-4 1 lines. 



Ilah. New Guinea, Port Moresby. 



Head convex, with a central longitudinal impressed line ; space 

 between the eyes deeply transversely grooved, limited in front by a 

 thickened oblique ridge. Antennae about half as long as the body, 

 obscure fulvous, the fourth joint nearly double as long as the third. 

 Thorax narrowly transverse, the sides slightly widened in front of 

 the base, the posterior angles rounded; surface rather convex, with 

 a few oblique obsolete depressions near the sides and the base, ex- 

 tremely finely punctured. Scutellum impunctate. Elytra widened 

 towards the middle, with a distinct flattened margin, extremely 

 closely and more distinctly punctured than the thorax, flavous ; a 

 transverse band at the middle (consisting of two spots united, of 

 which the outer one is the smallest), and a large oval-shaped patch 

 near the apex black. Underside and legs entirely flavous. 



Collection Jacoby. 



Megalognatha, Baly. 



5. Megalognatha cruciata, sp. nov. (Plate XLV. fig. 7.) 

 Elongate, convex, widened behind, fulvous ; head, breast, legs,
