Some corrections in literature on Hawaiian insects; and 

 other remarks. 



BY DR. R. C. L, PERKINS. 



At various times I have come across more or less serious 

 errors in my description of Hawaiian insects, which have not 

 been corrected by myself in print, nor so far as I know noticed 

 by others. 



In P. IT. E. S., p. 63, and in various other tables of species, 

 in referring to the genus Pseudopterocheilus I have inadver- 

 tently written "maxillary" for ''labial palpi." In my original 

 description of Odynerus pseudopteroclieiloides (Fauna Haw. I, 

 69), however, the words used are quite correct, "palpi lahiahs 

 pilis longis utrinque ciliatae." 



In P. H. E. S., I, p. 124, for "dotted" read "clothed." Op 

 cit., p. 112, our Lithurgus is stated to have 4-jointed palpi, but 

 there are really only three joints 



There is a curious error (F. Haw. II, p. 65) in respect to 

 the dragon fly whicli I identified as Agrion hoelense Blackburn. 

 The description of the $ characters agrees well with the series 

 taken, but for the figure of these parts (loc. cit. PI. V, Figs. 7 

 and Ta) a mutilated example was chosen, in which the terminal 

 segments were detached, as being easier for the artist to draw. 

 ISTow this example, assumed through carelessness to be the same 

 species as the rest of the series, happens to belong to A. amauro- 

 dytum, and therefore the figures do not represent .4. hoelense 

 at all. Whether Blackburn's A. hoelense is what I considered 

 it to be, or what I have called A. amaurodytum, I cannot tell 

 with certainty till I examine his species. The members of the 

 "Koelense" group of Agrions, that superficially resemble one 

 another, sJ^ow much variability, the species are closely allied, 

 and frequently occur mixed in the field, so they are not ex- 

 traordinarily easy to distinguish. The males are best distin- 

 guished by the form of the appendages.
