24 INSECTA MADERENSIA. 



wrinkled, and vnih an obscure longitudinal channel ; the margins broadly infuscate, a good deal 

 flattened, and recurved, especially behind. Elytra ovate, very much depressed, most finely and 

 minutely gi-anulated, and very deeply striated, — the strife interrupted at regular intervals, and 

 consisting of a series of elongated impressions which cause the surface to appear pitted or em- 

 bossed ; the lateral margins obscurely infuscate, and with a series of large ocellated impressions. 

 Antenna and legs long and slender ; the former fuscous ; the latter, especially the femora, very 

 pale testaceous. 



A very elegant and peculiar insect, and at once distinguished from tlie other 

 Zargi by its large size, flattened form, piceous hue, by its long, slender legs and 

 antennae, by its subcordate and comparatively elongated prothorax, and by its 

 deeply pitted elytra. It is found, beneath stones, in most parts of Madeira, though 

 seldom above the altitude of about 3500 feet. On the northern side of the island 

 it descends to the sea-shore, but on the southern its range does not commence so 

 low. It occurs very plentifully at times, making its appearance about the end of 

 summer and lasting until the following spring. On the western slopes of the Pico 

 do Cardo, near Tunchal, in the Chestnut-wood in the vicinity of the Mount Church, 

 as also in the north of the island, at the Passo d'Areia near Sao Vincente, on the 

 level of the beach, I have myseK captured it in considerable abundance. It seems 

 to be a species peculiar to Madeira proper, it not having been hitherto observed in 

 any of the other islands of the group.

Z. piceo-niger opacus depressus, prothorace parvo angusto rotundato-subcordato marginibus obscu- 

 rissime subinfuscatis, elytris leviter subinterrupto-striatis, lateribus antennisque subinfuscatis, 

 tarsis fuscis.

Z. black, with a very slightly piceous tinge, opake, and depressed, though not. quite so much so as 

 the last species. Mouth exceedingly prominent, and piceous. Prothorax short, small, much 

 rounded at the sides, being widest about the middle, slightly wrinkled, and with a tolerably 

 distinct longitudinal channel ; the margins very naiTowly and most obscurely infuscate, scarcely 

 at all flattened, and very slightly recurved behind. Elytra ovate, less depressed than in the 

 Z. Schaumii, most finely and minutely granuled, and lightly striated, — the stria: having gene- 

 rally a little tendency to be interrupted, though far less so than is the case in the last species ; 

 the extreme lateral margins most obscxirely infuscate, and with a series of large ocellated im- 



with the insects of that division of tlie Caralicla, since its entire general habit recedes from them altogether, 

 and bespeaks, m every respect, an intimate relation to the JI(n-j)alides. Added to which, the largely- 

 expanded and rounded joints of its male tarsi wovdd, even alone, at once remove it from the whole race of 

 the Brachinides.
