 costre basi ad medium disci jjerducta, ])ostice striis tribus vel qua- 

 tuor intcrruptis aurantiacis ; tibiis flavis. — Exp. alar. 5 lin. 



Inhabits Madeira proj)cr; occurring amongst damp fern and 

 herbage in the moist sylvan districts of intermediate and lofty 

 elevations. At the head of the 8'=* Cruz ravine, at S. Antonio 

 da Scrra, I observed it abundantly during June 1855. 



Ordo HEMIPTERA. 



Genus Pirates, Burm. 



Pirates niger. 



P. obscure niger, nitidiusculus ; tboracis sulco longitudinali hand 

 profundo, postice distinctissimo ; scutello inerassato, medio cavato ; 

 heinelytris fusco-nigris, immaculatis ; ])edibus anticis incrassatis, 

 tibiis apice subspathulatis. — Long. corp. 5\ lin. 



Inhabits Madeira proper; exceedingly rare. Detected by 

 myself, on the 6th of December 1848, beneath fallen leaves at 

 S. Antonio da Serra. 



Genus Sciocokis, Fallen. 



Sciocoris Sideritidis. 



S. umbriuus, griseo-variegatus, densissime rugoso-punctatus ; heme- 

 lytrorum membrana fusco-punctata ; capita supra subunicolori, 

 antice obtuse rotundato ; scutello ad apicem partis coriacese he- 

 mclytrorum vix extenso. — Long. corp. 2i-2f lin. 



Inhabits Madeira and the Dezerta Grande ; occurring on the 

 foliage of the Sideritis Massoniana, Benth., during the spring 

 and summer months ; and amongst fallen leaves at the roots of 

 that plant, and of the Sempervivum patina (Lowe, MS.) during 

 the winter. It is closely allied to the European S. umbrinus 

 (likewise found in the Madeira islands) ; it is, however, smaller 

 than that insect, its hemelytra are not quite so long (being 

 usually slightly shorter than the abdomen), its colour is darker, 

 or of a redder brown, its punctuation somewhat more dense, its 

 scutellum (although large) is proportionably smaller, and its 

 head is blunter (or less pointed) in front.

Rhijiiarochromus Maderensis.
