INSECTA MADERENSIA. 427 



intermixed. Antennm very long, and exceedingly hirsute, especially towards their base. Pro- 

 thorax rather small, with the sides produced into a robust central tooth ; its upper surface 

 unequal, with a somewhat small (though very elevated and distinct) transverse tubercular 

 glabrous prominence on either side of the disk, and an obscure, elongated, scarcely raised, central 

 one behind (forming a portion of the dorsal line) ; rather rough, and with the anterior margin a 

 little elevated. Elytra very coarsely and distinctly punctured, and more or less mottled with 

 cinereous pubescence. Antenna and legs brownish-ferruginous ; the apical portion of the former, 

 and the tarsi of the latter, being generally paler. 



A truly indigenous insect, occurring in most parts of the island at intermediate 

 altitudes, — though especially within the sylvan districts, and between the limits of 

 about 2000 to 4000 feet above the sea. It is nocturnal in its habits, and is con- 

 stantly attracted by the light of fires and candles in elevated spots. I have taken 

 it under such cu-cumstances at the bottom of the Ciu-ral das Preu-as, in Eebruary ; 

 as also in the region of the Ribeiro Prio, diuing August, — where I have likewise 

 frequently observed it drowned in the Levada, or have extracted it from out of the 

 dead branches of the trees which clothe the mountain- slopes.

The insect from which the above diagnosis has been compiled bears so strong a 

 superficial resemblance to Blahinotus, that it might be almost mistaken for 

 another species of that genus ; nevertheless a more careful examination wUl at 

 once disclose important characters in which it differs from it altogether. In fact, 

 the peculiar structure of the palpi, prothorax, and eyes, which constitutes the main 

 featm'e of Blahinotus, is here wanting, — ^siuce the palpi are exceecUngly short, with 

 the basal joint simple and the apical one scarcely secm-iform ; the prothorax is 

 rounded, beiug free from the iuequalities, tubercles and spines which are there so
