12 BULLETIN OF THE 



Exception should Le made to a small female (tegmiiia 48 mm. long) 

 which has heen left out of the table ; it is marked as from Indofatigal;le 

 Island, and is one of those reported on by Riley, but I think it must have been 

 wrongly labelled, for not only is it distinctly smaller than the smallest 

 other female from this island, but it diifers also from all of them in other 

 points in which both males and females from that island agree. These 

 points of resemblance are : in having the maculation of the tegmina subdued 

 and inconspicuous, as is common generally among specimens from nearly 

 all the islands (the single specimen in question being distinctly maculate 

 in fuscous on a subhyaline ground, much as in the Duncan Island specimens) ; 

 in having the metazona, or all except its extreme anterior portion, pallid 

 or clay-yellow, in strong contrast to the deeply infuscated remainder of the 

 thorax (the rejected specimen being uniformly light colored throughout, or 

 only darker on the posterior portion of the lateral lobes of the prozona) ; 

 and in lacking almost absolutely any light-colored quadrate patch on the 

 prozona near the upper limits of the lateral lobes, common in Schistocerca, 

 only one or two specimens showing a faint trace of it (while in this small 

 female the mark is distinct and set off by a brown edging). My belief is that 

 the specimen in question came either from Duncan Island (which is most 

 probable) or from Albemarle Island. It was collected by the "Albatross" 

 party of 1891.1 



In general also, but not invariably, the wings of the specimens from Inde- 

 fatigal)le Island are darker in the humeral and axillary areas, the cells in the 

 apical half being completely and often deeply infumated, and at the same time 

 the main rays of the anal area are infuscated and thickened; in this respect the 

 specimens from Charles, James, and Chatham Islands most nearly or often 

 quite resemble them ; so too, in all of these, the apical half of the anal area is 

 generally faintly infumated besides the infuscation of the veins. Finally, the 

 antenufe are generally luteous throughout in specimens from Indefatigable 

 Island with little or no apical infuscation, though this is occasionally tolerably 

 distinct ; the same is true only in the few specimens from James Island and the 

 single one from Chatham Island. 



The single female from Chatham Island, which agrees so well with the 

 average size of the females from Indefatigable Island, seems also to agree with 

 them in every other particular. I can find no feature in it which is not 

 generally found in the others, and of one specimen in particular it is almost 

 an exact duplicate. 



1 Since writing the above, which is left as first written, I have inquired of 

 Mr. Aiias?iz about tlie track of the" Albatross " in 1891, and learn from liini tiiat tbe 

 vessel did not touch at Albemarle Island, and that insects were collected only 

 at Chatham, Charles, and Duncan Islands. lie adds that one night was passed off 

 Indefatigable Island, and the party who went on shore, he among them, did not so 

 far as he recollects collect any insects , it was late in the evening when they 

 landed. There can therefore, I tliink, be little doubt that the specimen came from 

 Duncan Island.
