AND THEIR TRANSFORMATIONS. 29 



an irregular dusky or purplish striga ; but these strigje and dots are very variable, and sometimes, as in our 

 fig. 10, entirely obliterated. Taken in clover-fields and waste places in various parts of the south of England, 

 especially on the coast, and in the Isle of Wiglit, where I have taken it in abundance in August. One of my 

 specimens presents the singular case of having the two wings on one side of the body confluent.

Species 2. — Aspilates gilvaria''. — (Plate LXII., Fig. 11.) — This species measures from li- to nearly 

 1-J inch in expanse ; the wings are of a pale ochre or straw colour ; the fore ones freckled with brown, with a 

 central dusky dot, beyond which is a straight dark bar, which extends nearly from the middle of the inner 

 margin to the tips ; the hind wings whitish ochre, slightly pulverose, and with a central dot and fascia, more or 

 less distinct. The caterpillar is brownish, with pale stripes, and a dull green line down the back : it feeds on 

 Achillea millefolium. The perfect insect appears in August, and is found in difi"erent parts of Kent, especially 

 behind the Castle at Dover, in profusion.

Species 3. — Aspilates respersaria '. — (Plate LXII., Fig. 13.) — This dingy-coloured species measures 

 rather less than li inch in expanse ; the wings are of a pale dull grayish colour, thickly sprinkled with brown 

 atoms ; the anterior with four or more commonly only three, parallel, darker, yellowish brown, nearly 

 equidistant, straight strigse ; the two or three outermost of which are also represented in the hind wings. There 

 is, however, considerable diversity in the depth of colour, position, and clearness of these striga, some of which 

 are occasionally entirely obsolete. Specimens with four nearly equidistant striga;, form the Ph. G. strigellaria, jyr;/^ , 

 Hiib. Haw. Those with three equidistant strigse'are the G. respersaria of those authors ; and those with three, fi,J>. 

 but placed at imequal distances apart, the first and second being more approximated, form the Ph. G. injequaria. 

 Haw. The caterpillar is long, slender, and attenuated ; the back black, varied with whitish markings, and the 

 underside reddish brown : it feeds on the broom, and the moth appears in June, frequenting heaths where broom 

 abounds. It is a common species.

Aspilates purpuraria, LinnaBus ; Stewart ; Haworth ; Hiibner ; Stephens ; Wood, pi. 54, fig. 64, has the

PHASIANE, Duponchel. 

 This genus has the palpi long, porrected into a short pointed beak ; the antennse of the males very slightly 

 bipectinated ; the wings, with the apical margins, entire ; the fore ones with the tip acute, and marked with two 

 dark, slender strigse near the base, and another beyond the middle, where there is a single dark spot ; the hind 

 wings nearly destitute of markings.
