358 INSECTA MADERENSIA. 



Habitat in j\Iadera excels^ sylvatica, sub lapidibus truncisque arborum jsrolapsis, sestate rarior : ad 

 Lombo das Vacas d. 21 Jun. a.d. 1850, necnon ad Cruzinhas et Lombo dos Pecegueiros mense 

 Julio cjusdem anni cepi. 



C. nearly elliptical, much depressed, black, and densely clothed with very decumbent, golden-, or 

 greenish-brown pubescence. Rostrum short, and narrowed anteriorly ; longitudinally strigulose ; 

 and with a channel down the centre (sometimes replaced by a slightly elevated line), especially 

 apparent between the eyes, — which are oblong and depressed. Prothorax with the sides rounded, 

 but widest behind the middle ; deeply and remotely punctured ; and \rith indications of a slightly 

 raised keel on the disk. Elytra lightly punctate-striated, and beset with vei-y minute, short, 

 distant, and nearly erect hair-like bristles ; the under-pubescence having an exceedingly slight 

 tendency to assume the tessellated appearance which in the neighbouring forms is more or less 

 distinctly evident. Antenna and taisi pale mfo-ferruginous ; the latter sometimes almost testa- 

 ceous : femora and tibia more or less piceseent. 

 Male, with the legs broad and robust. The tibia crenulated internally ; the four anterior ones 

 concave beneath, and with a small inwardly-directed spine at their inner apex ; the two anterior 

 ones incurved (though especially at their extremity), and slightly expanded towards their inner 

 base ; the intermediate ones less distinctly so ; the hinder ones expanded inside into a large, com- 

 pressed, medial process, suddenly constricted before their extremity, — the extremity itself with 

 its external surface suddenly expanded out, the inner angle being rounded into an obtuse heel, 

 and the outer one being produced into a prominent and acute process or angle. 

 Female, with the legs much slenderer, but very slightly shorter ; entirely simple ; the tibia being 

 neither crenulated, hooked at their apex, nor dilated, — the two anterior ones however slightly 

 incurved at their extremity. 



Apparently extremely rare, and confined to lofty sylvan spots more or less 

 (lifiicult of access, — occurring beneath stones and logs of wood dui'ing the smiimer 

 months. I haA'e captured it on the Lombo das Vacas in June ; and at the Cru- 

 zinhas, and the Lombo dos Pecegueiros, in July.
