wbat wo have (lescrilml above as ix/ar was, tlierefore, certainly crroneniis ; his 

 suggestion that camu/ciisis might be leucophacata was likewise wide of the mark. 



i. Tenth abdominal tergite similar to that of Protoparce quinquemaculatus, 

 more cylindrical, less compressed ; sternite elongate triangular, straight, obtuse, 

 lateral margins very feebly turned upwards, very faintly notched, ('lasper straight 

 ventrally, strongly rounded apically, dorsally gradually and rather strongly dilated 

 towards ape.x, the dorso-apical margin curved inwards, dorsal groove deep, bordered 

 ventrally by a prominent fold, which bears long bristles ; harpe strong, dorsal 

 and ventral margins almost straight and paralkd, apex sinuate, denticulate 

 (PI. XXXVIII. f 4). Penis-sheath (PI. XXIX. f '.)) produced into a long, 

 gradually narrowing, pointed lobe, which is bent to a hook. 



?. Vaginal plate (PI. XX. f. 16) not strongly chitinised, much folded 

 proximally : a longitudinal mesial groove, narrowing proximally, where the edges 

 of the folds which border the groove nearly touch each other above the vaginal 

 oritice ; within the wider distal part, behind the orifice, there is a rounded carina. 



Early stages not known to us.

c? ? . No black mesial line on mesothoracic tegula ; mesonotum always grey, 

 no black-backed form known ; black dashes on underside of abdomen comparatively 

 larger in the large form than in the smaller ones. Spines at outer side of first 

 segment of foretarsus and at the end of foretibia prolonged ; parouychiiim reduced, 

 without long lobe ; first segment of hindtarsus as long as hindtibia ; long apical 

 spur of hindtibia half the length of the first tarsal segment ; first segment of 

 midtarsus with comb, but the bristles rather stout and not much prolonged. 



c?. Tenth abdominal tergite elongate-triangular, sulcate above except at end, 

 which is convex, acute, and curved downwards ; underside concave ; sternite with 

 a broad and rather long lobe, which narrows somewhat to the end and is feebly 

 sinuate. Clasper sole-shaped ; harpe (PI. XXXVIII. f. o) divided by a broad distal 

 sinus into a broad ventral lobe and a long horizontal jirocess ; the ventral lobe is 

 concave, the upper and lower margins being bent inwards, especially the upper, 

 which is irregularly and distinctly notched, while the distal and ventral edges are 

 almost smooth as a rnle ; the slender process is cylindrical, tapering towards the 

 pointed end, curving u])wards a little, reaching the apical fourth of the clasper. 

 Penis-sheath (PI. XXIX. f 11) iiroduced into a long, narrowing, pointed, somewhat 

 twisted and curved process. 



?. Vaginal jilate (PI. XX. f. 17) with a wide apical cavity of which the 

 bottom is smooth, without a tubercle, the plate not divided mesially as in 

 jicrelcgans, lialmiac, and lanceolata, but the slit indicated by some longitudinal 

 wrinkles. 



Larva with dispersed granules, which are denser on the thorax ; head distinctly 

 narrowed above. — Food : Syringa, Fraainu.^, JJgti.^fnim.
