CURCULIONIDiE. — LYPRUS. 49 



Sp. 5. tibialis. Nigro-fuscus, ehjtris squamuUs cinereis subnebulosis, punctisque 



duobus pallidis, tibiis piceo-ferrugineis. (Long. corp. 2 lin.) 

 Ba. tibialis. Steph. Catal. 158. No. 1607. 



Dusky-black; thoj-ax immaculate : elytra slightly clouded with ashy scales, each 

 with a rather distinct round pale spot on the disc towards the apex, which is 

 slightly attenuated; behind the discoidal spot is an obsolete tubercle : femora 

 dusky ; iibice pitchy-ferruginous. 



Taken, but not commonly, near London. 



Genus CCXCI. — Lyprus, Schdnherr. 



Antennae geniculated, 11-jointed, short; funiculus G-jointed, its two basal 

 joints somewhat longest and obconic ; the four following short, coarctate, sub- 

 perfoliate; club large, oval. Rostrum elongate, cylindric, bent, inserted 

 during repose in a deep pectoral groove reaching to the base of the anterior 

 pair of legs : thorax subcylindric, a little rounded in the middle ; the anterior 

 and posterior margins truncate : elytra elongate, subcylindric, attenuated to- 

 wards the apex, compressed : femora clavate, unarmed ; tibia: a little bent 

 within near the apex, which is furnished with a stout hook ; tarsi slender, 

 compressed. 



The 11-jointed geniculated antennse of Lyprus, united to tlie 

 subcylindric, compressed, elongate body, and pectoral groove for the 

 reception of the rostrum, are the most essential external characters 

 of this singular little genus ; which, like the Bogoi, revels among 

 aquatic plants, and is most frequently enveloped in earthy matter. 



Sp. 1. cylindrus. Nigricans, cinereo-squamulosis, antennis tibiisque fusco-fer- 



rugineis. (Long. corp. 1^ lin.) 

 Rh. cylindrus. Gyllenhal—Ly. cylindrus. Steph. Catal. 15'8. No. 1608. 



Linear-elongate, dusky, with ashy scales: head rounded, finely punctured: 

 eyes brown : thorax with a transverse impression within the anterior margin, 

 the disc finely punctate : elytra obsoletely punctate-striate, with the interstices 

 slightly coriaceous : femora black ; tibiae dusky-ferruginous ; tarsi fuscous : 

 antennje piceous, or dusky-ferruginous. 



Found on aquatic plants, especially upon Lemna and Sisymbrium, 

 but apparently very rare in Britain : my specimen was given to 

 me by my friend J. Scales, Esq. " On water-cresses in the 

 London market." — Jfr. Beck.
