and throat are not deep black, but rather brown. Moreover the 

 hidden parts of the body-feathers are greyish brown. 



The type of my A. inornatus is larger, is deep black all over, even 

 on the head, has all the feathers of the upper parts, back, upper 

 tail-coverts and wing-coverts, and also the feathers of the neck and 

 breast, distinctly and sharply edged with shining green, turning to 

 blue near the hind neck, so that all these parts appear beautifully 

 scaled: this scale-like appearance is completely wanting in the hen 

 of A. erythrophthalmus. Lastly the hidden part of the feathers does 

 not incline to brown, but is only greyish towards the base. 



The accompanying figure (Plate XLVIII.) taken from the typical 

 example, will give a good idea of A. inornatus, which is the third 

 known species of the Acomus group.

[Eeceived June 14, 1879.] 



A further collection of Butterflies recently received from the Rev. 

 G. Brown, has enabled us to clear up a few doubtful points in our 

 former papers on this subject, and to add several very interesting 

 species to the list hitherto known from these islands. Materials are 

 still wanting to render the determination of the Lycsenidae satis- 

 factory ; but as regards the larger species Mr. Brown sends us better 

 specimens in every collection, so that little is now wanting in their 

 condition. Judging from the fine new species contained in each col- 

 lection, we have no doubt that many more remain to be discovered. 



Cyllo amabilis, Boisd. Voy. Astr. Lep. p. 140, Atlas, t. 2. f. 1, 2. 



A single example of this very distinct species from New Ireland 

 agrees with the figure above quoted. 



Atella egista (Cram.). 



Mr. Brown has sent us two specimens which probably are refe- 

 rable to this species. They differ, however, in a slight degree from 

 our examples from Ceram and Amboyna, and- also from Cramer's 

 figure (Pap. Exot. t. 281. f. C, D), iu having the submarginal 

 row of black spots on the secondaries almost obsolete ; but we are not 

 inclined to consider this of specific value.

Diadema auge (Cram.). 



A single female example from the Duke-of-York group of islands 

 is identical with specimens in our collection from Moreton Bay and 

 Sula Islands which we refer to this species.
