LINNEAN SYSTEM. 



This is the common Spanish fly : it is found on tlie privet, the ash, 

 the elder, the poplar, &c. It is so light when dried that fifty of them 

 scarcely weigh a dram. 



Genus 37..Melof,. 



Antcniice moniliform : thorax nearly round : elijtrn soft, flexible, and 

 shorter than the abdomen : head inflected, gibbous. {PL 4. fig. 7.) 



Sp. 1. Md. .Proscurab/eus. Of a violet colour. 



Found in spring, i)articularly in open sandy fields, feeding on the 



different species of Ranunculus, &c.; its ova have an agreeable smell; 



when touched, there issues from it a very limpid yellowish oil, which 



is exceedingly diuretic, and when mixed with honey or oil has been 



recommended in cases of hydrophobia. 



Genus 38. Mordella. 



J[;i^en??tf' moniliform or pectinated: palpi four, the anterior ones cla- 

 vated, the hinder filiform : when frightened, it hides its head be- 

 neath the thorax : chjlra narrower towards the apex, and slightly 

 cui'vcd : before the thighs a broad plate at the base of the abdomen. 

 The insects of this genus inhabit flowers. 



Sp. 1. Mord.fasciata. {PL L fig. 8.) 



Genus 39. Staphylinus. 



I shall omit the generic character of Liime, and refer the student to 

 those genera given in Dr. Leach's system. JMr. Marsham has de- 

 scribed only 87 species of this very extensive family : 500 species at least 

 are found to be natives of this country, many of which are exceed- 

 ingly minute, but very interesting. {PL 1. Jig. 10, 11, 12, 13 4" 11-) 



Genus 40. FoREicuLA.

Order II. IIEMIPTERA. 



RIany of the insects of this Order are furnished with a rostrum 

 which is inflected and bent inwards towards the breast. Their wins;- 

 cases are hemelytratcc, or of a substance less hard than those of the 

 preceding order; they do not meet together and form a longitudinal 

 suture, but have some part of their anterior uiargins crossed or laid 

 one over the other.
