NOTES ON THE HEMIPTERA OF THE HAWAIIAN 

 ISLANDS. 



By Rev. T. Blackburn, B.A. 

 (Communicated by Hon. W. Macleay, F.L.S.) 



In my collection of Hemiptera from the Hawaiian Islands there 

 are a few species that it seems desirable to describe of which I 

 have only a single specimen in sufficiently good condition to be 

 treated as the type of a species, and a few which occurred to me 

 only immediately before my departure from the islands^ when I 

 had not time to examine them. I propose now to furnish 

 descriptions of some of these, together with remarks on certain 

 other species that it is not practicable for me to name on the 

 existing material, and some general observations. 



SCUTATINA. 



In this family ^Echalia is the predominant form. It is 

 extremely abundant on various trees (especially Aleurites) at 

 almost all elevations exceeding 1000 feet above the sea. I see 

 Dr. White (Ann. and Mag. of Nat. Hist., May, 1878) considers 

 that I have sent him two species (2Mtruelis, Stal, paci/ica, Stal). 

 I do not feel very fully satisfied myself on this point. It is 

 difficult to obtain two precisely similar specimens of the genus; 

 and though I was at first disposed to believe the species 

 numerous, I ended by being unable to divide them at all. How- 

 ever, I bow to superior authority. I have a single specimen from 

 the north-east of Hawaii — a very much narrower and more 

 parallel insect than the common one — which seems distinct ; but 

 it is mutilated and unfit for descx'iptiou, and, moreover, may be 

 uE. grisea, Burm., (of which I have not seen the description).
