HEMIPTERA 575 



(4) Nesosteles peregrina, sp. nov. 



Yellowish green or green. Abdomen below partly faint fuscous. Membrane 

 hyaline, veins yellowish green. Wings hyaline, veins faint fuscous. Vertex flatter 

 than in the other three species, distinctly wider in the middle than at the eyes. 

 Length 2^ mm. 



A Kilauea specimen is the type. 



Hab. Oahu, Honolulu, comes to light (Kirkaldy) ; Hawaii, Kilauea (Perkins and 

 Giffard). Probably not endemic. 



Macrosteles Fieber. 



Macrosteles Fieber, 1866, Verh. zool. bot. Ges. Wien xvi. 



I know only a single Hawaiian species, which appears to be endemic. 



(i) Macrosteles kilaueae, sp. nov. 



Bright yellow, legs etc. paler. Eyes greenish grey. Apical cells of tegmina 

 hyaline, with yellow veins. Wings hyaline, veins white, sometimes partly fuscous. 

 There is no appreciable sculpture, except microscopic. Vertex wider between the eyes 

 than its length, and wider than the eyes together, lateral margins slightly divergent ; 

 rounded obtusely anteriorly, somewhat convex, roundly obtuse in profile ; frons some- 

 what convex. Pronotum wider than the head and a trifle longer, lateral margins short, 

 not keeled, hind margin slightly obtuse-angulately emarginate. Tegminal venation not 

 very unlike that of M. punctifr-ons, but the first apical vein is sublongitudinal, not sub- 

 transverse, and the fourth vein is also longer and more longitudinal. 



%. Sheath blackish brown. Length 4^ mm. 



Hab. Hawaii, Kilauea. I have seen only one carded ?, in Dr Perkins' collection. 



Phrynomorphus Curtis. 



Phrytiovwiphiis Curtis, 1833, Ent. Mag. i. p. 194. 



Athysanus Burmeister, 1838, Gen. Ins. i., Jasstis. 



Athysanus subg. Athysanus and Conosanus, Osborn and Ball, 1902, Ohio Nat. u. 

 232 (not subg. Commellus which is part oi Deltocephalus, sens. lat.). 



The synonymy of this and the allied genera is complicated and as the Hawaiian 

 representative is an introduced form, it is unnecessary to dilate here on the generic 

 nomenclature.
