Tarucus clathratus, Holland. Plate XIV, fig. 16 $. 



T. clathratus, Holland, Proc. Bost. Soc, xxv, p. 71, pi. 5, 

 f. 8 (1891). 



Holland describes his species thus : — ■ 



" Near T. {Plebeius) fascialus, Roeber ('Iris,' vol. i, p. 194), but 

 smaller and differently marked. The upperside of the wings is 

 lilac, with smoky grey margins. The black markings of the under- 

 side are distinctly visible from the upperside. In fascialus the 

 submarginal black line is narrow, in clathratus it is broad. In the 

 former the two succeeding black lines are distinct throughout; in 

 the latter they unite, forming a rude figure of the letter Y. There 

 are many other minor differences which readily reveal themselves 

 upon a comparison of the two species, and which are more easily 

 seen than described. The type, a male, is in my collection." 



The habitat is Celebes, and I quite concur in Dr. Holland's 

 opinion that his species is distinct from Rober's. I have 

 no doubt, however, that Grose-Smith's T. Jluvialis is the 

 female of Holland's clathratus. Smith gives a long and 

 careful description of his species, a female, which also 

 comes from Celebes, saying that it is nearest to T.fasciatus, 

 Rober, but that the arrangement of the bands on the 

 underside is quite different, and then he goes on to say 

 that " it may not improbably be the female of T. clathratus, 

 Holland, but that his figure is so diminished that it is 

 impossible to decide with certainty whether this is the case." 

 I have enlarged Holland's figure, and find that the pattern 

 is precisely the same below, only in the original, being a 

 male, the bands are narrower than in the Tring type. 

 The underside shows through in just the same manner, 

 and I do not think there can be any doubt as to the identity 

 of the two insects. 



Tarucus leopardus, Schidtze. Plate XVH, fig. 18. 



T. leopardus, Schultze, Philippine J. Sci. D., 5, p. 161, 

 pi. 1, f. 9 (1910). 



The species was described in the Philippine Journal of 

 Science. The following is a copy of the description : — • 



" ^. Upperside of wings iridescent, purplish blue with a narrow 

 dull black line along outer margin ; cilia white. Tail black, tipped 

 with white. Hind-wing with two indistinct submarginal spots at 

 posterior angle. Underside of wings white with a faint ochraceous
