Convexus, nitidus, ater, marglnihus 2iedlbusque obscure rufcscentibus, an-

A single specimen occurred to me among loose stones on Manna 

 Loa, Hawaii, at an elevation of about 6000 feet. 



I feel some doubt about the generic position of the subject of 

 the above description. It is clearly a member of the Anchomenoid 

 series ; and I am unable to detect well-defined structural characters 

 to separate it from Cyclothorax (in which genus I therefore place it 

 provisionally) ; buc it will be desirable to point out («) that the slight 

 elevation of the prosternal process betwieen the anterior coxfe (Eut. 

 Mo. Mag., vol. xvi, p. 109) is scarcely to be traced in this insect ; 

 (V) that superficially it differs considerably in appearance from any 

 Cyclothorax yet known to me, inasmuch as it might be compared to one 

 of the most elongate species of that genus, furnished with the thoi'ax 

 of Pterostichus minor. Sab lb. 



The Berliner entom. Zeitschrift, Bd., xxv, 18S1, contains a paper 

 by Dr. F. Karsch on the Coleoptera that Dr. O. Finsch collected in 

 1872 on the Hawaiian Islands and elsewhere. The learned author, 

 probably, had not seen my series of papers on Hawaiian Carahidce, 

 since some of the species he describes as new are evidently identical 

 with some previously described by me. I may observe that Olinda — ■ 

 where most of Dr. Finsch's insects appear to have been taken — is a 

 locality in which I have collected at various seasons of the year, and 

 with the ordinary insects (at least) of which I am fairly well 

 acquainted. I venture the following remarks on Dr. Karsch's species 

 and determinations. 3i 



Acupnlpus hiseriatus, Karsch. This seems to be identical with
