<??. Antenna one-third (c?) or less than one-third (?) the length of the 

 forewing, not obviously incrassate before the hook ; apical segments see PI. LX. f. 9. 

 Spines of foreleg not prolonged, first protarsal segment as long as segments 

 2 to 4 together ; mesotarsus without comb ; spnrs without spines ; hindtibia 

 not spiny, long apical spur more than half the length of the first tarsal segment, 

 this longer than the four other segments together ; paronychium with long 

 slender lobes. The black antemedian band of the hindwing is either isolated, 

 or is more or less merged together with the discal band ; in the latter case 

 the discal band has a more proximal position than in the former. Extreme 

 individuals of the second form are called ab. spiraeae ; this is neither local nor 

 is it produced only by such caterjiillars as feed on Spiraea. In this ab. spiraeae, 

 as well as in individuals with separate antemedian band, the hindwing has 

 sometimes very little or no red, reminding one of 11. dnipiferarum. A specimen 

 in the Tring Museum, bred from a larva taken in 1890 at Hemel Hempsted, 

 Herts., by Mr. Arthur Wilson, has the black colour much more developed 

 than any other example we have seen, the greater part of the forewing, the median 

 band of the upperside of the abdomen and the underside of the latter \)eing 

 brownish black ; the discal band of the hindwing is broad, but the antemedian 

 band is distinctly separated from it, though the slightly reddish interspace is, like 

 the i)ostdiscal interstitial band, shaded with brown. A $ from Harrow-on-tlie-Hill 

 has scarcely a trace of i)ink. 



(?. Tenth abdominal tergite long, subcylindrical, gently curved, distally 

 flattened, apex divided into two sharp points (PI. XXVIII. f. 16) ; sternite (PI. 

 XXVIII. f. 17) with a very long horizontal lobe divided into two long slender 

 processes, which are cylindrical, tapering to end. Clasper broad, dorsally rounded, 

 ventrally oblique, broadly rounded at end ; harpe (PI. XXXVIII. f. 19) ending in 

 a broad concave plate, the ventro-distal margin of which is turned up and somewhat 

 notched, while the oblique dorsal edge is irregularly dentate ; the harpe bears some 

 resemblance to that of Protoparce sesquiplex (PI. XXXVI. f. 12). Penis-funnel 

 (PI. XXVIII. f. 40, p-f) rounded ; penis-sheath (PI. XXVIII. f. 40) ending in a 

 rather short, broad, obtusely rounded process. 



? . Vaginal ])late (PI. XXI. f. .5) obviously different from that of the allied 

 species ; the month of the vagina (v) is proximal, the middle of the postvaginal 

 plate is flat, slightly concave at the sides, convex in middle, smooth, and bordered 

 laterally by an oblique fold, which is often irregularly folded transversely.
