390 MODERN CLASSIFICATION OF INSECTS. 
The eighth family, Lirnositp# Stephens, is of small extent, and 
difficult location, having the body slender (fig. 107. 10. Lithosia 
quadra), the antennze generally slender and setaceous, and occasion- 
ally pectinated or ciliated in the males; the mouth is considerably 
more developed than in many of the preceding moths (fig. 107. 11. 
head of Deiopeia pulchella after Savigny ), the maxillze being long (with 
the maxillary palpi exceedingly minute and biarticulate in Deiopeia 
pulchella, according to Savigny) and spiral, and the labial palpi of mo- 
derate size and 3-jointed (fig.107. 12. labial palpi and base of the 
maxillary of D. pulchella), the third joint being small, and in some 
cases apparently soldered with the preceding; the thorax is not 
crested ; the wings comparatively of delicate structure, elongated, and 
whenat rest carried horizontally, the inner margin of one of the fore 
wings lapping over the same margin of the other. The larvee (fig. 
107. 9. larva of Lith. quadra) are cylindrical, often somewhat hairy, 
with six pectoral, eight ventral, and two anal feet ; they are solitary in 
their habits, never residing either in a case or in a general tent-like 
web. In their habits the perfect insects are weak and inactive; they 
fly rarely by day, although the brilliant colours of some of the species 
would seem to indicate a contrary habit. Their flight is short and 
feeble. 
This family is closely related to such of the aberrant Arctiidae as 
have an elongated spiral tongue, such as the scarlet tiger moth, 
Hypercompa Dominula; indeed Latreille places them as genera in 
one and the same group without any sectional division; they, how- 
ever, make a very near approach to the Yponomeutide, as is evident 
from such insects as Eulepia cribrum and Yponomeuta Evonymella 
(Latreille, Consid. Général. p.81.): hence, insome of his works, 
Latreille places his Tineites after this family, and preceding the 
Noctuidae. Mr. Stephens considers them so closely allied to the last- 
named family, that he unites them together to form his section Noc- 
turna ; but this relation appears to me to be too slight to warrant 
such a step. Many very splendid exotic species appear to me to 
constitute a passage between these insects and the aberrant Anthro- 
ceridee. 
The larva of the beautiful Deiopeia pulchella offers a remarkable 
agreement with the imago in its colours being whitish with red and 
black spots; that of Callimorpha Jacobzeee, which feeds in consider- 
able numbers upon the ragwort, is quite different from its imago, in 
being dark golden coloured with black rings.
