piceous ; post^ior margin of eacli segment ochreous ; Connexivum, 

 a brown spot on each segment. 



Length, 2 lines. 



Rare. Some old examples in the late Mr. Curtis' s collection had 

 a ticket attached, stating that the species had been taken in profu- 

 sion at Stockton, in November, in the seed spikes of Typha latifolia, 

 by the Eev. G. T. Eudd. 



Genus 2. — Ischnorhynchus, Fieb. 



Short, oval, convex, slightly shining. 



Head broad, 5-sided : Face triangular ; central lobe longest, 

 apex obtuse ; side lobes broad at the base, narrow and pointed in 

 front. Antennce inserted on a tubercle in front of and below the 

 eyes ; 1st joint stout, reaching a little beyond the end of the face; 

 2nd and 3rd thinner, 2nd rather longer than the 3rd ; 4th fusiform, 

 as long as the 2nd. Fijes large, semiglobose, prominent. Ocelli 

 distant. Mostrx m reaching beyond the metasternum ; 1st 3 joints in 

 length subequal, the 1st in a channel, of which the sides in front are 

 considerably raised. 



Thorax. — Pronotum trapezoidal ; anterior margin nearly straight ; 

 sides a little constricted in front ; hinder angles j)rominent ; poste- 

 rior margin rounded, with a deflection on it within the hinder 

 angles, but not extending to the centre ; disk convex, in front with

 anterior margin. Scutellum broad, triangular ; base with a deep 

 transverse depression, the rest convex, almost ridged and keeled. 

 Elytra longer and broader than the abdomen ; Corium convex, thin,

 considerably rounded, the margin recurved ; posterior margin a little 

 concave ; the nerves on the disk very fine ; Membrane broad, lustrous, 

 transparent ; the two outer nerves only arise at the base, curve and 

 proceed to the posterior margin ; the other 3 arise at a point just 

 within the apex of the corium, and curving suddenly outside one 

 another, proceed to the margin. Sternum flat in the centre, the 

 posterior margin of each segment raised and covering the basal i of 

 each coxa ; on each side, between the 2nd and 3rd coxa>, attached 

 to the anterior margin of the metasternum is a longish, distinct,
