ORDEU I. COLEOPTERA. 53 



Their lar\'fe are in general of an oval shape, somewhat elongated and 

 soft, with six feet near the head. Tlie last joint of their feet or tarsi 

 consists of four articulations, which in most cases serve for sexual di- 

 stinctions, the tarsi of the fore feet being considerably broader in the 

 males than in the females. This numerous and beautiful tribe is found 

 in almost every situation : their motion is slow ; and some of them 

 when caught emit an oily liquor of a disagreeable smell. 



In this genus of Linne we tind many insects that differ widely from 

 the generic character given above, which form many natural families 

 consisting of numerous genera, the characters of which will be given 

 in the system proposed by Dr. Leach. 

 Sp. 1. Chrys. coriaria. Apterous, oval; varies in colour from a dark 



blue to a black. It is a very common species, and may be found oa 



heaths from April to June in abundance. (PI. "i.fg. 12.) 

 Sp. 2. C/uys. Tunacdi. Black and punctTued: the antennie and feet 



black. {PL 'i.fig. 13.) Galeruca Tanaceti, Gcoffroy, Latreille, Fabri- 



cius, Olivia; and Leach. 

 Sp. 3. Clirys.mirdigcra. {PI. I.fig- H.) Auchenia merdigera, Manliam. 

 Inhabits the white lily. 



Genus 10. Cryptocepiiaixs, Fabr. 

 Antenntc finform : pulpi four : thorax margined, but not the elytra : body 



nearly cylindrical. 



The insects of this genus in some of the sections into which it has 

 been divided by Gmelin resemble the preceding in form and manners, 

 and were accordingly in the former editions of the Si/stcma Natures ar- 

 ranged with Chrysonield. Mr. Marsham's Auchenia, Crioccria, and TilluSj 

 are separated from this genus. 

 Sp. 1. Crypt. Lineola. Body black : elytra red, with a black line on 



each. {PI. 2. fg. 15.) 



Genus 17. Hispa. 



AntenneE cylindrical, approximate at the base and seated bet^veen the 



eyes : palpi fusiform : thorax and elytra often spinous or toothed. 

 Sp. 1. Hispa mutica. {PL 2. fig. 16.) Orthocerus muticus, Lair. 

 Inhabits sandy situations. 



Genus 18. Bruchus. 

 Antenntz filiform: palpi equal and filiform: lip acuminated. 

 Sp. 1. Bruchus Pisi. Elytra black, with white spots; the extremity 



white, with two black dots. {PL 2. Jig. 17.) 

 Inhabits Europe, and is very destructive to fields of peas.
