 and three on the sides of the abdomen. 



Bufirestia biguttata. Fabr. Oliv. Marsh. Latr.

 very rare, but was once observed in very great abun- 

 dance, by Dr Latham, in Darentwood, Kent.

 ed ; elytra with slightly elevated spaces, and transverse 

 undulating bands of white hair.

 tibiae, and tarsi red-brown; head punctate; thorax 

 rough, with elevated punctures, having an impressed 

 dorsal line ; elytra finely rugulose and striated. 



Elater bufirestoides. Linn. 



Melasis Jlabellicornis. Oliv. Panz. Fabr. 



Melasis bufirestoides. Latr. 



Inhabits Germany and the south of France. In Eng- 

 land it has been once taken, by Mr John Curtis of Nor- 

 wich, a most industrious entomologist. 



Genus LX. Cerophytum. La,tr. 



Tarsi with the last joint bifid. 

 • Sfi- 1. Elateroides. 



Tribe VI. Elaterides. 



Mandibles notched, or bifid at their extremities. An- 

 tennae filiform. Body leaping. Hinder thighs with a 

 trochanter. 



Genus LXI. Elater. Linn. Fabr. Geof. De Geer, 

 Fabr. Oliv. Lam. 



Obs. This genus should be divided into several others, 

 ut the characters have not yet been developed. In 

 Latreille's Genera Crustaceorum et Insectorum, we find 

 several sections, of which we shall give some account. 

 The last joint of the tarsi is not notched. The maxil- 

 lary palpi much exserted. 



* The last joint of the antennae with the apex so ab- 

 ruptly acuminated as to give the appearance of a twelfth 

 joint. 



Sfi. 1. Ferrugineus. Antennae serrated; colour black. 

 Thorax, with the exception of the hinder margin and 



elytra, red, finely punctuated, pubescent; elytra with 

 punctured striae. 



Elater ferrugineua. Linn. Fabr. Oliv. Panz. Marsh. 



Inhabits rotten trees, especially willows. In Britain 

 it is very rare. It sometimes occurs in Kent, varies in 

 size, and occasionally is found with the thorax entirely 

 black. This last variety is in Dr Leach's collection. 

 ** Last joint of the antennae oval or oblong, not abrupt- 

 ly acuminate. 



1. Body not linear, but tnree times as long as broad ; 

 abdomen oblong-triangulate. 



A. Antennae (of the male at least) pectinated or ser- 

 rated. 



Sfi. 2. Castaneus. Antennae of the male pectinated ; 

 colour black; head and thorax red-tomentose ; elytra 

 yellow punctate-striated; apex black. 



Elated Castaneus. Linn. Fabr. Panz. 



Inhabits Europe. 



B. Antennae simple; joints conic. 



Sfi. 3. Murinua. Black-fuscous, clouded with cine- 

 reous down ; thorax bituberculate ; antennae and tarsi 

 red. 



Elater murinus, Linn. Fabr. Marsh. 



Inhabits Europe. Is common on thistles. 



2. Body linear, nealy four times longer than broad ; 

 thorax oblong-quadrate. 



Sfi. 4. Marginatus. Black ; front retuse ; antennae, 

 sides of the thorax, feet, anus, and hinder margins of 

 the abdominal segments brownish-yellow; suture and 

 outer margin of the elytra, black. 



Elater Marginatua. Linn. Fabr. Oliv. Marsh. 



Inhabits Europe. Is found on various herbaceous 

 plants in fields.
