Genus CCCLXXXIV.— Leptura, Auctorum. 



Palpi vfith the terminal joint elongate, slender, sub-obconic, with the apex trun- 

 cate. Antennce more or less elongate, slender, nearly as long as the body; 

 basal joint robust; second minute, subglobose; third and fifth of nearly 

 equallength; fourth shorter; sixth longer than the fourth; the remainder 



, gradually diminishing in length to the apex : head nutant, exserted : eyes 

 slightly emarginated interiorly : thorax subtrapeziform, unarmed, smooth, or 

 nearly so : coleoptra generally elongate-subtrigonal, gradually narrowing from 

 the base to the apex; the latter frequently emarginated: legs elongate, 

 slender, iTiostly unarmed, that is without spines on the outer edge of the tibiae. 



From Toxotus, the present genus may be at once recognized 

 by the elongation of the terminal joints of the palpi, which are 

 moreover slender and truncate at the apex : but like the insects of 

 the genus just mentioned, the body is generally very much at- 

 tenuated posteriorly, by which the greater number of the species 

 differ from Pachy ta ; the elytra are also very frequently truncate, 

 or excised, at the apex : — the sexes are rarely dissimilar. 



A. With the elytra more or less cut out at the apex. 

 Sp. 1. elongata. Nigra, griseo-puhescens, ehjtrisjlavis fasciis quatuor nigris 



anteriore scepe punctatd, secunda interruptu, antennis Jlavo annulatis. (Long. 



corp. 5—7^ lin.) 

 Le. elongata. De Geer.— Donovan, iilpl. 84./. i.—Steph. Catal. 207. No. 2070. 



Black, with a short griseous down : thorax elongate, with an obsolete tubercle 

 in the middle of each lateral margin, the hinder angles very acute: elijtra 

 yellow, with four black fas ciw, the first composed o/ three or four round spots, the 

 second interrupted towards the suture, the third broader and emarginated pos- 

 teriorly, the fourth at the apex : four anterior legs yellow, with the apex of 

 the tibiae and the tarsi black ; posterior black, with the apex of the femora and 

 of the tibiae yellow : antennae with the two basal joints black, the rest with 

 the base yellow : the apex black. Male with the elytra attenuated, the posterior 

 tibiae bidentate within, and the antenna; nearly black : female with the hinder 

 tibiae simple, and the base of the abdomen yellow. 



Extremely variable : in some instances the anterior fascia is obliterated ; in others
