feet elevation. Tliis larva was brought home alive aiul molted 

 a few days later, linally pupating on ]Mareh 27 and issuing as 

 adult on April 3rd. It was fed on small partially crushed or 

 stunned Diptera, mostl}' Drosophilids, but probably would have 

 accepted other insect food if it had been offered. The beetle 

 assumed a blackish brown coloration within 24 hours after 

 emergence, but up to the present (x\pril 5) it still presents an 

 immature appearance. The larva was of the usual Carabid 

 type. 



At least two other species of Metromcnus captured on 

 ^larch 4th hiding in moss on trees on Mt. Kaala were exhib- 

 ited, these having been kept alive by feeding them with small 

 Diptera. 



Note on the Non-Identity of a Common Hawaiian Jassid with 

 Nesosteles hebe Kirkaldy of Fiji. 



Kirkaldy in 1J)10 (Fauna Hawaiicnsis, vol. 2, pt. G, 

 p. 574) identified one of the common grass-inhabiting Jassids 

 of the Hawaiian Islands as Nesosteles liehe which he had de- 

 scribed in 1906 (Ent. Bull. 1, H. S. P. A., p. 343) from Fiji. 

 Recently the writer took occasion to examine the male geni- 

 talia of specimens from Fiji and found that there were good 

 specific differences between them and the genitalia of Hawaiian 

 specimens. The dorsal plate or valve of the genitalia in both 

 species is produced into a strong hook on each side. In the 

 Hawaiian species the hook is simple but in liehe it is armed at 

 the base with three or four small but distinct spurs. The 

 aedeagus also presents some differences. Kirkaldy called atten- 

 tion to a small difference in the coloration, and thought that 

 the Hawaiian specimens might possibly be distinguished as a 

 variety, for which he proposed the name Jiospes. This name 

 must be elevated to specific rank for our local form. Kirkaldy 

 also identified an Australian insect as ]ieJ)e, but this has en- 

 tirely different genitalia.
