iridescent , its punctiiation moderately close , rather coarse in front, 

 finer bebind, in tlie middle near the front are two conical tubercles. 

 Elytra of a peculiar dark red colour with undulating patches of iri- 

 descence which appear to change their position as the light varies, 

 they are very finely striated, the suture and humeral tubercles blackish, 

 tlie interstices are without any trace of punctuation. The pygidium 

 is reddish, pitchy towards the extremity, the basal part is dull and 

 indistinctly punctured , the apical part shining and more distinctly 

 punctured. The under surface is black, with the sides of the abdomen 

 in immediate contact with the elytra reddish; the sides of the sternum 

 bear a rather long pale pubescence, the raetasternum is punctured at 

 its front angles , the under surface of the anterior feniora coarsely 

 punctured, middle ones with coarse punctures at the extremity only; 

 the front tibiae are moderately stout, their teeth rather long ; the legs 

 are black with the tarsi pitchy. 



Waigiou (Wallace!). 



This species extremely romarkable in its colour, presents so far 

 as I see no corresponding peculiarities of structure. 



Onthophagus quaestus (n. sp.): Ohlongus, nigcr, nitidus, antcnnis 

 flavis, pedibus piceis; clypeo vix emarginato, margine anteriore medio in- 

 crassato, vertice summo ca/rinato; thorace mutico ; elytris striatis, inter- 

 stitiis pundatis; tibüs anterior ihus gracilihus, paulo elongatis, dentibus 

 extus truncatis, calca/ri apicali crasso, intus porredo, deorsum curvato. — 

 Long. 6'/2 mill. 



Clypeus ronnded in front, the middle slightly prolonged and re- 

 flexed, evenly, moderately finely and not closely punctured , the disc 

 with an indistinct obtuse transverse elevation , the summit of the 

 Vertex carinate. Thorax rather closely and distinctly punctured at 

 the basis, more finely and sparingly on the disc, the sides distinctly 

 margined, the basal margin indistinct except in the middle. Scutel- 

 lum with its apex reaching the level of the surface of the elytra but 

 not prolonged between the suture. Elytra rather long , distinctly 

 crenate-striate, the interstices distinctly punctured , not so shining as 

 the thorax. Pygidium closely and rather coarsely punctured. Sides 

 of prosternum depressed in front (subfoveolate). Metasternum conically 

 prominent in the middle in front , all the middle part evenly and di- 

 stinctly, not densely punctured, the sides coarsely punctured, the epi-
