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 Liliacese, Aspargi, Sec, 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 j their own 

 faeces, with which they cover their back, protect 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 merdigera, 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 Memoires 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.; 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 Aucheniae 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 Megascclis.
