spots emitting hairs. It feeds on willow, ash, nettle, &c., and the moth appears in June; but is by no 
means common, although widely dispersed, having been found in Kent, Surrey, Devonshire, Dorsetshire, 
Hampshire, Oxford, Huntingdonshire, Cambridge, Yorkshire, &c. 

FAMILY VIII.—LITHOSIIDA, Srzpuens. 
This family is of small extent, and difficult location, having the body slender, the antennz generally slender 
and setaceous in both sexes, but occasionally pectinated or ciliated in the males; the mouth is much better 
developed than in many of the preceding moths, the maxille being long (with the maxillary palpi exceedingly 
minute and bi-articulated in Deiopeia pulchella, according to Savigny) and spiral, and the labial palpi of 
moderate size, and three-jointed, the third joint being small and, in some cases, apparently soldered with the 
preceding ; the thorax is not crested; the wings of comparatively delicate texture, elongated, and when at 
rest, carried horizontally or convoluted, the inner margin of one of the fore wings lapping over the same 
margin of the other. The larve are cylindrical, and often 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 few species indicate them to be day-fliers, Their flight is short and feeble. 
The family is closely related to such of the aberrant Arctiide as have an elongated spiral tongue, such as 
Heraclia Dominula: indeed, Latreille places the Lithosiz in the same group as the Arctize without any 
sectional division ; they, however, make a very near approach to the Yponomeutide, as is evident from such 
insects as Eulepia cribrum and Yponomeuta Evonymella; hence in some of the works of Latreille, the Tineites 
of that author (including Yponomeuta) are placed immediately after the present family and preceding the 
Noctuide. Mr. Stephens considers them to be so closely related to the last-mentioned family, that he unites 
them together to form his sub-section Nocturna ; but this relation appears to me to be too slight to warrant 
-such a step. Many very splendid exotic species appear to constitute a passage between these insects and the 
aberrant Anthroceride. 

CALLIMORPHA, Larreitiz (nec Borspuvat). HEUCHELIA, (e.) Borspuvar. TY RIA, Hisner. 
Independently of the peculiarity of colouring of the type of this genus, it is distinguished by the breadth 
of the wings, which form a triangle when closed, the antenne slender, those of the males emitting two short 
bristles from each joint; the palpi have the joints of nearly equal length, but decreasing in thickness; the 
spiral tongue is elongated, but not so long as the antenne; the thorax is small, and the abdomen elongate, 
being cylindrical in the male, but shorter and more ovate in the female. The caterpillar is clothed with a few 
long straggling hairs only; it is of a pale colour, annulated with black, with sixteen feet; it changes to an 
obtuse chrysalis in a slight cocoon under ground. 
As Latreille expressly gives Phaleena Jacobee as the type of his genus Callimorpha in the Regne Animal, 
the nomenclature of Mr. Stephens is adopted in preference to that of Boisduval, who makes Dominula the type 
of Callimorpha, and unites Jacobez and pulchella into a new genus, introducing miniata (rosea) into the genus 
Lithosia.
