Genus Asychna, Staint. 

 Asychna inmlaris. 



A. alls anticis saturate olivaceo-fuscis, stria angusta aurantiaca a 

 costse basi ad medium disci perducta, postice striis tribus vel qua- 

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



Inhabits Madeira proper ; occurring amongst damp fern and 

 herbage in the moist sylvan districts of intermediate and lofty 

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

 da Serra, I observed it abundantly during June 1855. 



Ordo HEMIPTERA. 



Genus Pirates, Burm. 



Pirates niger. 



P. obscure niger, nitidiusculus ; thoracis sulco longitudinali baud 

 profundo, postice distinctissimo ; scutello incrassato, medio cavato ; 

 hemelytris fusco-nigris, immaculatis ; pedibus 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 Sciocoris, Fallen. 

 Sciocoris Sideritidis. 



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

 lytrorum membrana fusco-punctata ; capite supra subunicolori, 

 antice obtuse rotundato ; scutello ad apicem partis coriacese he- 

 melytrorum 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. 



Genus Rhyparochromus, Curt. , 



Rhyparochromus Maderensis. 



R. supra sparse et rude punctatus ; capite, thorace scutelloque nigro-
