15. ACE^A ASTRIGERA, sp. 11. (Plllte XXV. fig. 5.) 



(S . Allied to A. acara var. barberi, but having the size and 

 general aspect of the largest and brightest examples ot" typical 

 A. acara ; on the primaries the spots oi: the postmediau series are 

 small and arranged in a regular line (as in A. ucrita) ; the bar 

 crossing the end ot" the cell has a small spot below it, and exactly 

 resembles that in A. anemosa • the looped submarginal line ot" 

 A. acara is ouly represented by two dusky dots beyond the lowest 

 spot of the postmedian series ; the secondaries have no white 

 patch and no black spot on the discocellulars ; the black outer 

 border is as wide as in A. acara, but is more sharply defined and 

 traversed by a series of pure white dots ; the fringe also is pure 

 white between the veins : on the under surface the differences 

 between this species and A. acara are of the same kind. 



(S . On the road from Maehako's to Naugia, 4800 feet, 18th 

 September. 1898. 



Although this is a beautiful insect in its fresh rosy colouring, I 

 could wish to have seen more specimens before describing it; 

 because, while it is perfectly distinct and well-marked, yet the 

 possession of a female example wo.uld have shown whether it 

 should be placed neai'er to A. acara or A. anemosa. It appears to 

 come nearer to the former.

 "Very plentiful : has to be almost driven off the ground — flies 

 so low." {Ji. C.)

 " By no means common ; three seen in a day's walk." {R. C.) 

 It is satisfactory to find that this species, of which we previously 

 possessed only the type, is quite constant.
