COLEOPTERA. 125 
Criocrnris, Geoff., Oliv.—Lxma, Fab.—Curysomera, Lin., 
Or Crioceres properly so called, are removed from the preceding by 
this character: their posterior legs are similar to the others, or differ 
from them but very slightly; the antenne become somewhat and 
gradually enlarged towards the extremity and are almost granose, 
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 Liliacee, Aspargi, &c., and, like those of 
the preceding family, make a slight noise when siezed. Their larve 
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 
feeces, with which they cover their back, protect them from the action 
of the sun and the changes of weather. In order that they may ac- 
complish this, their arms are placed above. When about to become 
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 published, 
in the Memoires de la Société Linneenne de Paris, some ob- 
servations on the C. brunnea—Lema brunnea, Fab.—which is 
fulvous, with the antennze, pectus, and base of the abdomen 
black. It is found together with its larva, on the Liliwm con- 
vallaria, 
C. asparagi; Chrysomela asparagi, L.; Oliv., Ib, II, 28. 
Bluish, with a red thorax, sometimes immaculate, and sometimes 
with a blue and cordiform spot in its middle ; the elytra are yel- 
lowish, 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 *. 
Aucuenta, Thunb. 
The Auchenie 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 
antenne which are wider; and by their thorax, which is dilated near 
the middle of each side into an angle or tooth f. 
Sometimes the mandibles are truncated; the palpi are terminated 
by a strongly inflated truncated joint, with a little annular prolonga- 
* See Olivier and Fabricius, but without including the leaping species, some of 
which belong to the subgenus Petauristes, and the others to the last one of this 
family, or Megascelis.
