FOSSIL PLANTS OF BRITAIN. 543 



Another very flat genus, the precise locality of which, in 

 the system, I have not yet ascertained, though it may be near 

 Phytocoris, wants the ocelli, and is of an oblong elliptical form, 

 the head being small and somewhat square, with a distinct 

 neck behind the rather prominent eyes ; the thorax is nar- 

 rowest in front, gradually increasing in breadth behind, scu- 

 tellum large, as is the coriaceous part of the hemelytra ; legs 

 long and fringed with hairs ; antennce wanting in our speci- 

 men, all but the basal joint, which proceeds from a slightly 

 projecting lobe on the upper side of the head ; the beak is 

 short, not reaching far beyond the first pair of legs : the spe- 

 cies is 7 lines long, and nlay be characterized as follows. — 



Caliprepes Grayii. 



C. virescenti-luteus, thorace maculis 2 dorsalibus posticis triangularibus, 

 scutello 2 basalibus, rubris : hemelytrorum parte coriacea, linea apicali 

 transversa, viridi, — membranacea, linea basali obscura.

Named in honour of George Robert Gray, Esq. late Secre- 

 tary to the Entomological Society of London, whose works 

 on insects, but especially on Orthoptera, must always rank 

 among the most important Entomological publications of the 

 present day.

NEUROPTERIDES, Gopp. 



Frond simple, pinnate or bi-pinnate. Secondary veins issuing in num- 

 bers from the midrib, which does not extend to the apex of the pinnule ; 

 or, all the veins are forked, and rise in a fan-shaped manner from the base 

 of the pinnule; the midrib being scarcely apparent. 



Neuropteris, Brong. 



Frond pinnate or bi-pinnate. Pinnce or pinnulce cordate or subcordate 

 at their base, rarely adnate or decurrent. Midrib thick, not extended to 

 the apex, secondary veins numerous, slender, usually forked and curved. 

 Sori lanceolate, even, (with an indusium), arising from the veins of the apex 

 of the pinnule, and often placed on the bifurcations.
