41. Oxyhammus derolius spec. nov. 



S. Brown-black, covered with a very short elayish olive tomeiituiu, which gives 

 the insect a dark slaty-grey appeanuice ; antenna] segments 4 to 11 grey at base; 

 scutellum creaui-colonr, conspicnons; a thin basal mesial line on pronotum also 

 creamy ; no other markings. Frons jialer pnbescent at sides than in middle. 



Head and thorax without any jiunctures, except three or four at prothoracical 

 spine. Lower lobe of eye vertical, a little wider vertically than cheek. Antenna three 

 times the length of the body ; scape smooth, throe times as long as aiiically broad 

 (apart from the narrow basal portion) ; third segment a little more than twice as 

 long as scape, a third longer than segment 4. Prothorax a little longer than 

 basally bro.ad ; apical and subapical transverse sulci distinct and regular, bnt obsolete 

 above in middle ; no tubercles on disc ; side-spine conical, rather short. Scutellum 

 rounded. Elytra depressed, truncate at base and apex, with the shoulders and 

 sutural angles rounded, and the outer angle produced into a short spine ; coarsely 

 punctate-striate, the punctures distinct to apex, but here much smaller than at 

 base and not seriated ; base grannlose. Mesosternal process slightly convex, not 

 tubercnlate, but also not grooved. 



Length, 12 mm. ; elytra, 7| mm. ; breadth, 3§ mm.

Two SS. 



In appearance similar to Ox)/hammus scutellaris (1893) Kolbe, but with a 

 simple mesosternum, and a shorter apical spine and no basal tubercle to the elytra. 

 Besides, the scape of ilerolius is shorter, the elytra arc more coarsely punctured, and 

 the subapical sulcus of the pronotum is obsolete above in middle. In the shape of 

 the mesosternal process t/eroliiig stands intermediate between ordinary AfonockMnus 

 and the species described by me as M./idraster (1894), Nov. Zool. i. p. 194. n. 152 

 (Kuilu). This fulmster has a strongly convex, anteriorly vertical mesosternal 

 process, and truncate and externally acuminate elytra, and belongs to Oxijhammas. 

 Since the relationship of ileroliKS and sciitellaris cannot be doubted, the only 

 character by which to distinguish Moiiochamus and Oxijhammas would be the 

 tooth at the end of the elytra. 



42. Oxyhammus (V) cinctus spec. nov. 



<?. Black ; underside, head, antenna and legs greyish white, the i)ubescence 

 short and not very dense, on prothorax extending upwards to disc, forming in 

 dorsal view a sinuous lateral vitta. A thin interrupted mesial line on pronotum, 

 scutellum, a large humeral patch on elytra extending obliquely towards suture, 

 a transverse, slightly sinuous band across the elytra just behind middle, broadest 

 at lateral margin, where it is connected with the humeral patch, produced frontad at 

 suture, an apical band, and the tips and extreme bases of the antennal segments, 

 white ; the ])ostmedian band of the elytra slightly buflfish. 



Head, thorax and femora impunctatc, excej)ting a few punctures at the base of 

 the prothoracical spine. Lower lobe of eye not wider than cheek. Antennal 

 tubercles short, the depression between them more obtuse than in the previous 

 species. Antenna of i a little longer, of ? a little shorter than the body ; scape
