12 INSECTA MADERENSIA. 



Grandi montes inde a 1000' s. in. usque ad cacumina prsecipuc occupat ; sed in Portu Sancto, 

 Deserta Boreali, et in insula prope promontorium Sancti Laurentii Maderse " Ilheo de Fora " dicta 

 fere ad maris litus descendit. 



S. black, shining, slightly depressed. Head large, with two deep longitudinal depressions on the fore- 

 head. Prothorax transverse, wide in front, narrower and rounded posteriorly, with an impressed 

 transverse line behind the front margin, and a channel down the disk. Elytra ovate, with the 

 humeral angles a little prominent, but not projecting beyond the outer margin, deeply striated, 

 the striae being impunctate ; with the entire margin (basal as well as lateral) thickly and more or 

 less coarsely granulated, aud with a single row of tubercles (more or less distinct) throughout. 

 Antenna and le^s (especially the tibia and tarsi) piceous ; the last seven joints of the former 

 densely clothed with a fine yellowish pubescence, and the latter thickly fringed with strong 

 golden or rufous bristles. 



Var. a. extremely shining. Elytra short, ovate, expanded behind the middle; the basal margin 

 thickly and coarsely granulated, and with a row of distinct tubercles. {Madeira.) 



Var. /3. shining. Elytra short, ovate, expanded behind the middle ; the basal margin with scarcely 

 perceptible granules, but with a row of rather distinct tubercles. [Porto Santo.) 



Var. y. shining ; with the head and prothorax rather narrower than in the other varieties. Elytra 

 rather longer, and a little expanded about the middle ; the basal margin granulated (though not 

 very distinctly), and with a row of tolerably distinct tubercles. [Ilheo de Fora.) 



Var. 8. shining, very large. Elytra long, and a little expanded about the middle ; the basal margin 

 with scarcely perceptible granules, but with a row of exceedingly distinct tubercles, the outer or 

 humeral tubercle being the largest. [Northern and Central Dezertas.) 



This is the commou Scarltes of the Madeira Islands, and it may be known, in 

 all its varieties, from the S. hmneraUs by its brighter surface and less parallel 

 form, by its humeral angles, although a little prominent, never projecting beyond 

 the outer edge of its elytra, and by the more granulated margins of the latter, 

 which have, in every case, a row of tubercles, more or less distinct, along their 

 entire lengtli, lateral as well as basal. It ranges from the sea-shore to the extreme 

 summits of the loftiest mountains. In Madoii-a proper, however, it is most abun- 

 dant between the Kmits of about 2000 to 5000 feet a1)ove the sea ; whilst in Porto 

 Santo, the Plat Dezerta, and on the Ilheo de Pora it descends to the level of the 

 shore. On tlic Dozerta Grande it is attached principally, as in Madeira, to the 

 higher altitudes, Ijcing extremely common in the fissu^res of the weather-beaten 

 rocks of the most elevated peaks ; where the specimens moreover attain a very 

 large size, — although they are scarcely perhaps so gigantic as those on the nortliern 

 island, in which the average length is from 13 to 16 lines. The Madeiran speci- 

 mens are smaller, and more shining, than any of the other varieties.
