nose, their joints not being much longer than they are wide. The 

 eyes are prominent and emarginated. The posterior extremity of 

 the head forms a sort of neck, behind these latter organs. 



These Insects live on the Liliaceae, Aspargi, &c., and like those 

 of the preceding family, make a slight noise when seized. Their 

 larvae feed on the same plants to which they cling by means of their 

 six squamous feet. Their body is soft, short and inflated; their own 

 faeces, with which they cover their back, ^-otect them from the 

 action of the sun and changes of weather. In order that they may 

 accomplish this, their arms are placed above. When about to be- 

 come nymphs they enter the ground. The 



C. merdigera; Chrysomela mei-dtgera, L. ; Oliv., Col., VI, 94, 

 i, 8, is three lines in length, with the thorax and elytra of a 

 beautiful red. The thorax is strangulated on each side. The 

 elytra are marked with longitudinal lines of punctures. In all 

 Europe on the white Lily. 



M. Boudier, of Versailles, a zealous entomologist, to whom 

 I am indebted for several rare and curious species, has pub- 

 lished in the Memoircs de la Societe Linneenne de Paris, some 

 observations on the C. brunnea — Lema brunnea^ Fab., — which 

 is fulvous, with the antennae, pectus and base of the abdomen 

 black. It is found together with its larva on the Lilium conval- 

 laria. 



C. asparagi; Chrysomela asparagi, L. j Oliv., lb., II, 28. 

 Bluish, with a red thorax, sometimes immaculate, and some- 

 times with a blue and cordiform spot in its middle; the elytra 

 are yellowish, with a blue band along the suture, which, being 

 united with three lateral spots of the same colour, forms a 

 cross. 



The same plant is devastated by another species— the C. 12- 

 punctata^ L. — which is fulvous, with six black spots on each 

 elytron(l). 



AucHENiA, Thunb. 



The Auchenia^ differ from the Crioceres, with which they were at 

 first confounded, by their entire eyes; by their palpi narrowed and 

 terminated in a point, and not obtuse; by the last seven joints of their

 of which belong to the subgenus Petauristes, and the others to the last one of this 

 family, or Megascdis.
