INSECTA MADERENSIA. 14.9 



P. elliptical (being widest about the middle, and almost equally attenuated before and behind), convex, 

 bright piceous, shining, and free from pubescence. Prothorax ample, wide behind (whore it is 

 closely applied to the elytra), more or less rufescent, and covered, both above and below, with 

 shallow but rather large punctures. Elytra generally rufescent towards their apex, extremely 

 minutely and distantly punctured, — the punctm-es being scarcely perceptible except under a high 

 magnifying power ; when they will be observed moreover to be slightly disposed in rows. 

 Mouth, antenna and legs ferruginous. 



The small size, in conjunction with the glabrous, shining, and elKptical body, of 

 this interesting insect will readUy distinguish it from the remainder of the Coly- 

 diadcB here described. It is confined exclusively to the forest districts of Madeira, 

 where it would appear to range between the limits of from about 2500 to 5000 

 feet above the sea, occurriag more especially, as might be expected, in those spots 

 which, from the difficulty of access, have been least disturbed. It is found either 

 beneath bark or in the interior of rotting wood, — occasionally even adhering to 

 the undersides of wet decaying logs, particularly in regions where the moisture is 

 excessive, and where consequently decomposition goes on the most rapidly. I 

 have taken it at the base of the Pico Grande and in the Boa Ventura, durino- 

 February ; on the Lombo das Vacas, in June ; at the Lombo dos Pecegueiros, in 

 July ; and at the Feijaa de C6rte, at the beginning of August.

* Genus masiUarum forma elji^risque trimcatis Rhyzopliago simillimum, sed tarsorum struetura et 

 habitu general! Colydiadis affinitate proximmn videtur, et cum illis, nisi fallor, recte poneuduni est.
