ji:i'eater )>art lilack, forc-tiliiii at basf iiml apex, mid-tibia at ajiex witli iudistinct 

 black patches. 



\Vii)gs, above, smoky black. 



Forewing : semi-diaphanous, veins and margins denser scaled, the scaling not 

 forming a patch upon discocellulars ; a large j'ellow patch at base, occupjiug about 

 one-third of the inner margin and extending to M. 



Underside : forewing yellow at base ; hindwing yellow at costal margin. 



Clasper with a narrow, rather deep apical sinus, continued by an impression, 

 which makes the sinus appear deeper than it is, lower lobe prominent, longer 

 than upper, somewhat spoon-shaped. 



Length of forewing : 13 mm. 



Hab. Fergusson, d'Entrecasteaux Islands, October 1894 (A. S. Meek), 1 i 

 (tUlic) ; Milne Bay, Brit. N. Guinea, December 1898, 1 c?. 



In the Milne Bay example the yellow patch of the forewing is larger than in 

 the t'lpf. 



11. Zygaenopsis assimilis sp. nov. 



i. Thorax above, first and seventh abdominal tergites and antennae black, frons 

 fuscons with some yellow scales, sides of prouotum, palpus, legs, breast and abdomen 

 below pale yellow buff, abdomen above deep chrome yellow, first abdominal tergite 

 distally also with yellow scales. 



Forewiny : as in busalis, without lilack stigma, yellow basal patch consisting 

 of a streak occupying base of cell, and of a broader streak upon SM-, the streaks 

 joining each other at base. 



llindwini/ : below with the costal area from base to near apex pale creamy 

 buff; base of forewing also washed with the same colour. 



Clasper with an obliquely triangular sinus, the lower lobe narrow, obtusely 

 triangular, shorter than the upper, very broad, lobe, the clasper agreeing better 

 with that of .some individuals oijiavibasls than with that of basalis. 



Hnb. Salawatti (W. Doherty), one ? . 



Differs from basalis in the cell of the forewing being yellow at base, in the 

 first abdominal tergite being black for the greater part, and in the short ventral 

 lobe of the apex of the clasper. 



12. Zygaenopsis flavibasis. 



Z.flaribasis Swinhoe, I.e. p. 02 n. .'fis (1891) (Key); Hamps., I.e. (1900) 

 (p. parte). 



We have above referred to the variability in the nenration of the Key Islands 

 form. In the individuals from New Guinea and adjacent islands SC-' and SC^ are 

 always stalked together, but the stalk is sometimes very short ; SC'' is always given 

 off before SCI 



Clasper with a small but distinct sinus, both lobes obtuse. 



a. Z. flavibasis abdominalis snbsp. nov. 



S . Face, palpns, side of prouotum, has and the abdomen yellow ; first and 

 seventh tergite of abdomen black, legs scarcely with a trace of black scaling.
