AND THEIR TRANSFORMATIONS. 43 
Mr. Chant,” gives the Stomoxyformis of Stephens, as the female of Myopseformis ; whilst, to add to the con- 
fusion, Mr. Stephens (Illustr. Mand. v. 4, p. 69,) censures a “reference to my male Aigeria stomoxyformis, with 
ciliated antenne, as the female of Ag. culiciformis.” 
If, as Mr. Stephens at first stated, his specimen be a female, then the only difference which I can find between 
his descriptions of it, and of the female of the preceding species, is the colour of the under side of the fourth 
abdominal segment ; but in such case, Mr. Stephens’s description does not accord with Hiibner’s insect. If, on 
the other hand, the specimen in question be a male, then it is at once distinguished from all the other red-belted 
species by the colour of its palpi. 
Spoinx EpnemMermrormis of Haworth, referred to this genus by Haworth, Stephens, &c., belongs to another 
family. It is allied to Psyche, and has been subsequently described and figured by Mr. Stephens, from a drawing 
made by myself from Donovan’s original specimen, under the name of Thyridopteryx, in the Transactions of the 
Entomological Society: of London. 
FAMILY V.—HEPIALIDAL, Sreruens. 
(Zeuzerides, Boisduval ; Xyleutites, Newman.) 

This is the first family of the great division of night-flying moths, named by Linnzus, Phalena, and is 
distinguished by having the antenne generally short and filiform, never feathered to the tip ; the spiral tongue 
either obsolete or very short ; the palpi also generally obsolete ; the abdomen elongated, as are also the wings, 
which are deflexed in repose, the anterior pair exhibiting a striking peculiarity in the disposition of the veins 
quite unlike that of any other group, but which has not hitherto been noticed by any previous writer, and 
which may partially be perceived in our figure of Zeuzera Aisculi (pl. 9, fig. 5). The female is often 
furnished with an exsertile ovipositor. The caterpillars are long, fleshy, naked grubs, with a few straggling 
hairs. They are sixteen-footed, having six pectoral, eight ventral, and two anal feet. They are generally nearly 
colourless, and feed on the wood of trees, or at the roots of vegetables. When full grown, they construct a loose 
cocoon of the materials upon which they have been feeding. The pupz are elongated, and have the abdominal 
segments armed with transverse rows of fine reflexed spines or hooklets, which assist the insect in pushing itself 
out of its cocoon to the surface of the earth or the exterior of the tree—immediately before assuming the perfect 
state—the exuvia of the pup being found sticking in such situations. 
This family, which is of small extent, is closely allied in respect to its transformations to the Trochiliidee ; 
but the relation with the Smerinthi, suggested by Mr. Stephens, appears to me to be but slight, there being 
other species of the Linnzean Bombyces which much more nearly approximate to these insects.
