610 INSECTA MADERENSIA. 



though occuiTing (especially at low elevations toAvards the coast) both in Madeira 

 and Porto Santo. It is an exceedingly well-marked species, — its small size and 

 somewhat narrow outUne, in conjunction with its coarsely punctured head and 

 prothorax (the former of which has a deep transverse fovea between the eyes, thus 

 causing the clypeus to appear elevated behind), and its rather more shiuing sur- 

 face than is usually the case amongst the memljers of the present genus, being 

 sufficient, apart from minor distinctions, at once to characterize it.

O. minute, exceedingly narrow, fuscous, and opake. Head, prothorax and elytra coarsely and densely 

 roughened (the lust however having alone much tendency to longitudinal strigulation) : i)ie first 

 oblong and piceous ; with a very indistinct central impressed line behind ; with its extreme edges 

 minutely raised, deeply sinuated over the eyes (which, although small, are consequently a good 

 deal exposed, — and which, in my single example, are brownish-ferruginous), and the front 

 margin (though rounded) a httle more produced than in any of the preceding species ; the region 

 of the clypeus depressed (in a curved, and rather a sudden and regular, manner behind) : the 

 second short and transverse, brownish-ferruginous, with its discal sulci almost obsolete, and with 

 its extreme lateral margins just perceptibly roughened, tliough scarcely subcrcnulated : the last 

 of a rather duller hue than the prothorax, but not so dark as the head, — being somewhat fuscous. 

 Abdomen pale fuscous, with the hinder margin of each segment somewhat diluted in colouring. 

 Antenna distinctly longer than the head and prothorax (their basal joint being elongated, and 

 ■ subclavate at its apex), brownish-ferruginous, with their base (and the palpi) a little paler. Let/s 

 pale testaceous. 



Male (?) with the head about as wide as the anterior portion of the prothorax. The abdomen beneath 

 with the sixth segment truncated, and with the seventh broadly cmarginatcd. 



Female (?) as yet undetected. 



The unique specimen from Avhich the above description has liccn compiled pre- 

 sents so many points of discrepancy from the other O.vi/teli here described, that 

 there is but little fear of confoimding it with any of them. Apart from its minute 

 size and narrow outline, and the slightly jagged (or subcrcnulated) edges of its
