ORDER I. COLEOPTERA. 59 



pond, dttch, and rivulet, but many of the species are very local : they 

 may be obtained in the above-mentioned situations at all seasons of 

 the year. 



Genus 33. Carabus. 



AntenncE filiform; palpi six, the last articulation obtuse and truncated : 



thorax obcordate, trrmcated at the apex, and marginatcd : elytra 



margined. 



Mr. iMarsham has described 109 British species of this genus: the 

 generality of them are foimd on the ground, under stones, in sand-pits 

 &c. a few are found in trees, feeding on the larva? of Lepidopteru. The 

 whole of this tribe are very voracious, preying on all insects which they 

 can overcome; they discharge, when tsikcn, a brown caustic and fetid 

 liquor: many of them want wings; though their elytra in general are 

 separate and moveable: their larvai live in putrid wood, among mosses, 

 in the earth, &:c. 



PL 3.Jig. 17, 18, 19, <5- 20, belong to this genus of I.inne. They are 

 types of so many genera, the characters of which are given in the 

 system of Dr. Leach. 



Genus 34. Teneerio. 



AntciiniC moniliform; the last articulation nearly round : ^^omr with a 



small degree of convexity, and marginatcd : luad standing out: eli/tra 



.somewhat rigid. 

 Sp. 1. Teneb. Molitor. Brownish-black ; the anterior thighs the thickest. 



{PL 4. Jig. 1.) 



The larvas ot this insect are called ]\Ical-zoonns, and are found in 

 meal, bakers' ovens, dry bread, &c. They are of a pale colour, smooth, 

 with thirteen segments, soft ; and are the favourite food of nightin- 

 gales, and other JMotacilU. 



Genus 35. Blaps, Fair., Marsh. Teneerio, Linn. 



Antenna filiform; palpi four: thorax with a small degree of convexity, 



and marginated : head standing out : eli/ira somewhat rigid : zcings 



(in most species) wanting. 

 Sp. 1. Bl. mortisaga. Black ; coleoptra ending in a point, and smooth ; 



the antennae moniliform at the apex. 



This species wants the wings : it walks slowly, and is therefore called 

 the slow-legged beetle : when taken it emits a certain colourless but 

 very fetid liquor. 



Genus 36. Lytta, Tahr. Meloe, Linn. 

 AntenncE ^XiioxYO.: pa^^i four, unequal, the hind ones clavated: thorajs 

 somewhat round : head inflected and gibl)ous : elijtra soft and flexible. 

 Sp. 1. Lytta vesicatoria. Green; the antennae black. (PL 4;. fig- 5.) 

 Inhabits the south of Europe, and is occasionally found in Britain.
