This species burrows in cow-dungand under the eartli, digging deeP 

 holes; and is found plentiftd on heaths and commons during April 

 and May. Mr. Marsham in his Eutonwlogia Brilannlca has described 

 80 species of Scaruba-i found in this country. 



Genus 2. Lucanus. . 

 Antenna clavatcd; club perfoliate: imxilU prominent and dentated: 



bodi/ oblong : anterior tib'ut dentated. 

 Sp. 1. L. CciTus, the Stag-beetle. With a scutelhim; the maxillae 



projecting, bifurcated at the apex, witli many teeth on the internal 



edge. {PL i. Jig. '3.) 



This is the largest of the British Cokoptera; the larva is white, and 

 lives on putrid wood, particularly oak ; its head and feet are of a rust 

 colour. The perfect insect varies in size and colour; in general it is 

 dark brown or blackish; the jaws arc very large, about one third of 

 the Icnsth of the whole insect, and have a distant resemblance to the 

 horns of a stag; Mr. iMarshani's incnnis is only the female of this 

 species. 

 Sp. 2. L. parallclipipedus is considerably smaller, and may be obtained 



in June and July in the neighbourhood of willows. 

 Obs. L. ccmihoklcs has not yet occurred in Britain, at least no British 



specimen is known. 



Genus 3. Dermestes. 



Antenna daxated; the club perfoliated {PI. l.fg. 4. a.); the three ter- 

 minating articidations larger than the rest: thorax convex, with 

 scarcely any margin: head inflected, and partly hid under the thorax. 

 The larvae of the insects of this genus feed on decayed animal sub- 

 stances, and are exceedingly injurious to the meat in larders, skins, 

 furs, and books. 

 Sp. 1. D.murinus. Oblong; downy clouded with black and white; abdo- 

 men cover^ with fine white down or hair. 

 loJiabits Europe ; and may frequently be found in the dead moles hung 



up on the hedges by countrsmeu. (PI. l.Jig. 4.) 

 Sp. 2. D. Scol^tus. Elytra truncate, blackish and striate : abdomen re- 

 tuse: front downy and of an ash colour. {PL l.Jig. .').) 

 The insects of this genus arc very prolilic ; both the larvae and per- 

 fect insect eat the roots and wood of trees, and are sometimes very de- 

 structive to woods. The following account, from Mr. K irby's Introduction 

 to Entomology, of i5os/;7'(7(/(.s T^pograplum Fabr.,will further illustrate 

 the habits and manners of this genus: " This insect in its preparatory 

 State feeds upon the soft inner bark only: but it attacks this important 

 part in such vast numbers, 80;000 being somcthncs found in a single
