Notes on Hawaiian Plagithmysides and Anobiides (Col.) 

 with Descriptions of New Species.* 



BV R. C. L. PERKINS. 



The following notes have been made on examination of a 

 small, but very interesting collection of Hawaiian Longicorns, 

 submitted to me by Mr. O. H. Swezey, the greater number of 

 the specimens being from the collection of Mr. W. M. Giffard. 

 In most cases the trees from which the species were obtained 

 have been carefully noted, but a considerable number of speci- 

 mens were taken at large. The numbers attached to Mr. 

 Giffard's captures are here quoted, but the order is not pre- 

 served, because the same species is sometimes sent under num- 

 bers that are not consecutive, owing to the different circum- 

 stances under which the individuals were obtained. 



1. A dark specimen of Plagithiiiysus hlackhurni taken on 

 bastard sandal wood (Myoporinn sandivicense) on the high 

 plateau (6000 ft) Puulehua, Kona, Hawaii, by J. F. Rock. 

 Mr. Giffard's note says, "It was probably only restiug on that 

 tree." This is likely to be correct, as the species is common 

 on Mamani (Sophora chrysophylla) in the neighborhood, being 

 attached to that tree, and I have taken specimens on the wing 

 on the plateau. Dark examples occur also on Soplwra with 

 the paler ones. 



16. Three examples of a series taken on Mamani (Sophora 

 chrysophylla) at Puuwaawa, N. Kona, Hawaii, are also P. 

 hlackhurni and are quite similar to my own from that locality 

 and from Mauna Loa. 



17. Three examples from a series taken on Mamani 

 (Sophora chrysophylla) near Kilauea, Hawaii (4000 ft) are 

 rightly named P. darwinianus, and three others from a series 

 of twelve (No. 15) taken from a dead tree, which could not 

 be identified, but was not Sophora, are also typical specimens 

 of the same. Under ( 19 ) are two examples of darunnianns 

 from a series of Plagithmysus taken on XantJioxylum dipctalum
