We have a large series, about 200 specimens, of this species ; it varies much in size, 

 and a good deal in the development of the male characters. The varieties mentioned 

 above are not connected to the typical form by intermediates, except that one female is 

 almost entirely testaceous, with the elytra faintly infuscated over a large part, leaving 

 the disc clear yellow. Two female individuals from Kona have the serial punctures 

 more distinct than they are in the other specimens. 



The male characters of the pygidium are very slight in this species. The apex is 

 just perceptibly emarginate, but there is no projection of the angles or any trace of 

 tuberculation there ; the supplementary segment usually projects a little. In the female 

 the apex of the pygidium is very greatly rounded, being almost straight in the middle. 



In addition to the large series above alluded to from Hawaii we have small series 

 of the species from Lanai and from Molokai. 



The series from Lanai consists of one male and seven females. These individuals 

 have the serial punctuation of the elytra even more obsolete than it is in the Hawaii 

 form, the colour is darker, the elytra being more indistinctly metallic, and the female 

 pygidium is a little narrower at the tip. These characters are so slight that I do not 

 think it is necessary to name the form. The series of 20 specimens from Molokai is 

 very similar to that from Lanai, except that there is always a larger or smaller patch of 

 rufescent colour extending from the scutellum backwards along the suture of the elytra, 

 and in some specimens the elytra are nearly completely yellow. From Maui there is 

 but one specimen, and it agrees with the Hawaiian typical form. 



Hab. Hawaii, Lanai, Molokai, Maui. — Hawaii : Kona, 2000 to over 4000 ft., 

 some recorded as obtained from flowers and other parts of Freycinetia, Koa and other 

 trees; above Hilo 1800 ft.; Kaumana, Hilo, 2000 ft.; Olaa (Perkins); Mauna Loa 

 and Mauna Koa up to 5000 ft., from flowers of Freycinetia and other plants (Black-

Though extremely close to A^. metallescens this appears to be really distinct. We 

 have a series of about 88 specimens, and on the whole the individuals are not much
