species. I at once set to work and brought it to liglit, and below give 

 a description o£ it, as it does not appear to have been described 

 previously. The specimens were living when given to uie many years 

 ago by Mr. W. Wilson Saunders, who informed me that he thought 

 they had come amongst a lot of ferns he had had from the West Indies. 

 It being found feeding on the leaves of an orchid from Bahia, rather 

 conflicts with the foregoing statement, but Mr. Saunders may have 

 had other plants from abroad at the same time, and finding the creature 

 on the ferns made no further search for it. 



Genus Tenthecobis. 



Head almost twice as broad between the eyes as aci'oss the crown. 



Crown : anterior margin somewhat convex ; face almost perpendicular, slightly 

 convex, side lobes nearly as long as the central lobe, slightly convex exteriorly. 



Antennae placed at and close to the lower margin of the eyes, shorter than the 

 body ; 1st joint very short, 2nd elongate, gradually thickened from the base to the 

 apex ; 3rd almost cylindrical, about Ij times as long as the 2nd ; 4th and 5th thin, 

 together shorter than the 3rd ; 5th short, about 2^ times shorter than the 4th. 

 Eyes prominent, projecting beyond the anterior margin of the pronotura, viewed 

 from above almost globose, from the side oval, widest at the top. Eostrum reaching 

 to between the 2nd pair of coxse. Pronotum constricted in front, anterior margin 

 slightly concave ; lateral margins almost straight, gradually widening to the hinder 

 angles, across which the disc is more than twice as broad as the anterior margin ; 

 posterior margin convex at the sides, very slightly concave across the scutellum. 

 Scutellum triangular. Elytra : anterior margin convex, widest near the base of the 

 cuneus, from whence to the apex of the membrane it is very greatly deflected. 

 Membrane with one large triangular cell, the inner angle narrowly rounded. 

 Legs moderate. 



Tenthecoris bicolor. 



Deep steel-blue and red, shining. 



Head red. Antennae, 1st and 2nd joints red; apex of the former narrowly 

 black, of the latter more or less broadly clouded with black, sparingly clothed with 

 short semi-erect pale hairs ; 3rd black ; 4th and 5th yellow. Eyes very deep 

 purplish-black. 



Thorax : pronotum bright red, shining, finely punctured. Scutellum deep 

 steel-blue, shining. Elytra, clavus and corium very finely rugose, deep steel-blue, 

 shining ; anterior margin of the latter broadly bright red, the colour gradually 

 widening to the base of the cuneus, and sparingly clothed with short yellowish hairs ; 

 cuneus bright red, sparingly clothed with short sub-depressed yellowish hairs ; inner 

 angle deep steel-blue. Membrane darkish brown between the base and the apex of 

 the cell ; anterior margin and round the apex broadly pale, finely rugose, the wrinkles 

 running longitudinally ; cell darkish brown ; cell-nerve very dark brown, with a very 

 fine pale margin exteriorly. Legs vary in colour frpm reddish-yellow to red ; coxse 

 and fulcra generally yellow. r- 



This genus, in appearance, is not far removed from that of
