ORDER I. COLEOrTTRA. 59 



pond, ditch, and rivulet, but many of tiie species are very local : they 

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

 the year. 



Genus 33. Carabus. 



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



tfiorax obcordate, truncated at the apex, and marginated : eli/ira 



margined. 



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

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

 &.C. a few are found in trees, feeding on the larvx of Lepidoptera. The 

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

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

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

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

 in the earth, &c. 



PI. S.Jig. 17, 18, 19, c^- 20, belong to this genus of Linne. They are 

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

 system of Dr. Leach. 



Genus 34. Teneerio. 



Antenna', moniliform; the last articijlation nearly roimd: thorax w'wh a 



small degree of convexity, and marginated: head standing out: elytra 



somewhat rigid. 

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



(PL 4. fig. 1.) 



The larvae of this insect are called Meal-zcorms, and are found in 

 meal, l)akers' ovens, dry bread, &G. They are of a pale colour, smooth, 

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

 gales, and other Molucillcc. 



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



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



and marginated : head standing out : eli/tra somewhat rigid : wings 



(in most species) wanting. 

 Sp. 1. Bi. mortimga. Black ; coleoptra ending in a point, and smooth ; 



the antenna? 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, Fuhr. Meloe, Linn. 



Antenna filiform : palpi four, unequal, the hind ones clavated : thorax 

 somewhat roimd : head inflected and gibbous : elytra soft and flexible. 

 Sp. 1. Lytta vesical oria. Green; the antenna black. {PI. 4:. Jig. 5.) 

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