56 LINNEAN SYSTEM. 



phoric, proceeds from the last segment but one of the abdomen, and 

 seems intended to attract the male. Laihpi/ris splendidulu is said to in- 

 habit this country, but I have not yet seen any British specimen : I 

 should therefore advise those entomologists residing at a distance fronx 

 London to collect all the specimens they can oljtain, and carefully ex- 

 amine them : the males may be taken in profusion in the evenings of 

 the above months, if a few females be put in the entomologist's fold- 

 ing-net as he walks in the above places of an evening. 



Genus 26. Pyrociiroa, Tdbr. Gtncl. 



A)deuna; \)cct\natc : thorax orbicular: ioc/y elongate, depressed. Th.e 



prevailing colour in this genus is red and black. 

 Sp. 1. Pi/roch. coccineu. Black : thorax and elytra of a bright scarlet red : 



the antenna; strongly pectinate. 

 Inhabits the woods of Kent in the months of June and July. (P/. 3. 



f'S- 3.) 

 Sp. 2. Pijroch. ruhcns. Black : thorax and elytra of a duller red than 



the preceding species. 



A very connnon insect in the months of May and June, and may be 

 foiuid in most hedges where white-thurn grows. 



Genus 27. Caxtiiaris. 



AnteniKc filiform; thorax (in most species) marginated; f/y^;Y/ flexible : 

 the sides of the abdomen with papillary folds. 



This is an extremely rapacious genus, preying upon other insect§, 

 and even its own tribe. 



Sp. 1. Canth. fusca. Thorax red, with a black spot; elytra brown. 

 {PL 3. Jig. 4.) 



This is a numerous tribe, and forms several natural genera of mo- 

 dern authors. 



Sp. 2. Canth. higuttata. Thorax black in the middle : elytra greenish- 

 bronze; red at the apex. (PI. 3. Jig. 5.) 

 This insect is furnished with two red obtuse vesicles at the base of 



the abdomen, and two at the apex of the thorax, which are raised and 



depressed alternately. Common on various plants in woods in the 



months of May and June. 



Genus 28. Elater. 



Antenna fiViiorm: ^aZpj four, securiform : wfwrfiWcs notched, or bifid at 



their extremities. 



3\Iany of the coleopterous insects have a great difiSculty in restoring 

 themselves when, laid on their back; the apparatus with which the hx~ 

 sects of this genus are provided for that purpose is singular and curi- 

 ous. An elastic spring or spine projects from the hinder extremity of 

 the breast, and there is a groove or cavity in the anterior part of the ab-.
