EUOLIDIA MI. 



Plate CV, fig. 3. 



A moth of this species, taken on the 5th of June, 

 1886, at the Green Farm Wood, Doncaster, deposited 

 eggs which were globular in shape, the colour a dull 

 pale green. They hatched about the 28th of the same 

 month, and the young larvse were dingy green with 

 large yellowish-brown heads; when walking they looped 

 the back in the same way as does a geometer, and 

 when disturbed at once rolled themselves up and 

 feigned death. They fed well on grass and common 

 white clover, and by the 22nd of July were slender 

 creatures of about five- eighths of an inch long, with 

 only six ventral legs, and consequently were veri- 

 table " loopers," arching the back as much as any 

 geometer. On the 7th of August, when they were 

 almost an inch long, I described them as follows : 



Very slender ; head wider and deeper than the second 

 segment, the lobes evenly rounded ; body of nearly 

 uniform width throughout, rounded above, slightly 

 flattened ventrally ; skin smooth, the segmental divi- 

 sions clearly defined, but not deeply cut ; there are 

 only three pairs of ventral legs, on the ninth, tenth, 

 and thirteenth segments respectively ; the last pair, 

 when at rest, being stretched backwards and outwards, 

 give the appearance of a notched anal prominence. 

 Ground-colour generally dingy pale olive-green, in 

 some specimens, however, bright greenish-yellow ; on 

 it is a pretty ornamentation of chocolate-brown stripes 

 as follows :— First, a narrow and interrupted medio- 

 dorsal, then a double and more clearly defined one, 

 followed below at about the same distance by another 

 double stripe ; then follows a broader one, and imme- 

 diately adjoining it is the broad and conspicuous 

 lemon-coloured spiracular stripe ; all these stripes 

 extend in strong relief through the head. The ventral 

 surface has a somewhat similar but not so clearly
