l:!i;. Protambulyx euryalus sjir. nov. (J'l. I. I'. ;'., c? ; ]'I. LXVII. f. !>, S 

 S ?. Siniiliir to .1. ci/n/r/i'.s. Second alidorainal segment less grey above. 



^\'ings, Kppcrtiidi'. Fovewiiig : more buffisli, less grey, than in ein-ycles. Tlio 



(ili\(-iiri'en costal patches from the base to SC'' larger than in eurycles, the two 

 j)atches at the end of the cell and distally of it touching each other at the edL'c 

 of the wing, or nearly so, a distinct blackish brown marginal band of nearly evt'ii 

 width, tapering in front, limited by a blackish line which begins at the very extremity 

 of »SC* ; contignous with this line and standing at its proximal side an olive-green, 

 sharply defined band, wliicli is brt)adest between K' and K-, where it equals in 

 breadth the marginal band, while in enrycles the olive-green band is much less 



sharply defined, and much wider Ijetween R' and R-. Ilindwing : apex less 



pointed than in eurycles and anal angle less produced ; the jiostdiscal black band, 

 which in eurycles is distally concace between C and R'' and therefore angled at 

 the latter vein, is nearly evenly cnrved ; abdominal margin more grey in ? than 

 in enrycles. 



i'liderside, the line outside the cell of both wings and the jwstdiscal one of 



the hindwing rather heavier than in eurycles. Forewing : discal line closer to 



cell than in the preceding species ; the brown marginal area about 2 mm. broad at 

 SC\ while in eurycles it is narrowed to a point at the end of SO' ; the area is much 

 more even in width, being not much broader between R' and R- than at R-', while 

 in eurycles the area is much broader between R' and R- than at R' ; the posterior 



discal lines vestigial. Hindwing : the postdiscal line not concave between C 



and R2, but slightly convex ; no discocellular bar. 



S . The eighth abdominal sternite has mesially just a trace of a lobe (PI. XXII. 

 f. 22). The harpe (PI. XXXI. f. 1) has a submesial process (pm), and the 

 edge mdis also more raised than in eurycles. The penis-sheath (PI. XXX. f. 17) 

 has a longer and non-dentate apical ridge. The tenth sternite (PI. XXIII. f. 6) 

 is truncate, with the angles strongly rounded. The patch of scales on the clasper 

 is very broad (PI. LVIII. f. 32), at least three times as wide as in eurycles. 



? . Not dissected. 



Early stages not known.

In the lobe SO' of the forewing being less prominent than the apical lobe, and 

 in the marginal band of the underside of the forewing not narrowing to a point at 

 SO'', euryalus agrees with strigilis, while eurycles agrees in the same points with 

 .'^ulp/iurea. 



I'M. Protambulyx ockendeni spec. nov. (PI. LXVII. f. 7. s, d). 



d ?. Similar to .1. cui'yahix. 



^\'iug•s, uppcr»id,'. -Forewing less variegated, basal half more distinctly 



purplish ; olive jiroximal border of distal marginal band much narrower between 

 R' and R'. Hindwing : third discal line thinner, more even, less crenate. 



Underside. Forewing : lines SO' — SC"', situated halfway between fork and 



apex, converging behind, closer together, mostly merged together before SC* ; 

 marginal band ])ointed at tip of SC', less widened behind R' than in euryalus, 

 of more even width.
