in the above named district (the series consisting of danviniaiiiis 

 and his/iopi mixed) and under (20) four other individuals 

 from another series found on the same species of tree are also 

 darzuiniaiius. Whether this series consisted entirelv of the 

 latter or partly of bisJiopi I do not know. In July, 1906, I 

 obtained one or two specimens of darwinianus on a dying 

 XantJwxyhiin tree which was full of Plagithiiiysus larvae. 

 The tree was decaying and the bark gave out a strong odor. 

 h>om material carried away I subsequently bred a series of P. 

 bishopi, nine examples of which series I still possess. No 

 specimen of darzviniauus was bred, and I thought it probable 

 that those I took were merely attracted by the scent, the species 

 being" abundant on Sophora near by, but Mr. Gififard's expe- 

 riences lead one to suspect the probability of its breeding both 

 on Sophora and Xant/io.vyliini. 



14. Three examples of P. bishopi, being part of a series 

 taken on Pelea cinerca near Kilauea, are quite ordinary, as 

 also are two taken on Xantho.vyliim from a series of mixed 

 darwinianus and bishopi referred to above under (19). The 

 series that I bred from the latter tree showed no differences 

 whatever from another series (also bred) from Pelca. 



13. The larger specimen taken at 1800 ft. Olaa, 19 miles 

 from Hilo, Hawaii, resting on Mamake (Pipturus oVbidiis}, 

 is a not uncommon variety of P. lafnarckianns, in which the 

 pubescent lines of the elytra are yellow and very wide basally, 

 so that the insect closely resembles sulphiircscens in appearance. 

 It is, however, perfectly distinct from this, and lamarckianus, 

 so far as I know, always has red antennae in this variety, 

 while in sulphiircscens they are black. Sharp has specially 

 alluded ( F. H. II, p. Ill) to the alliance between these species. 



13a. The second and smaller example is of the more black- 

 legged variety, but also has flavescent lines of pubescence, and 

 was taken on Siiftonia — "no doubt an accidental capture" — at 

 3800 ft., Olaa. The flavescent color of the lines in lainarckiaiiiis 

 is not a constant character of the species. I have myself bred 

 specimens from the same piece of Pipturus both with pure 

 white and with flavescent lines, and no doubt these soon fade 

 to white, so that the latter color is likely to be more usual in
