598 FAUNA HAWAIIENSIS 



parallel. First segment of antennae annuliform, second short, not reaching to the base 

 of the clypeus. Tegminal veins feebly granulate, five apicals, the second forked near 

 the base. Spur with 5 — 6 spines. $. Ovipositor scarcely as long as the pygophor. 

 Tegmina reaching well beyond the apex of the abdomen. Length 3-| mm. 



Hab. Oahu, Tantalus (Feb., 1906, Perkins, ?), ridge near Tantalus (Dec, 

 Swezey, $) ; Kauai, Koloko (800 ft., Giffard, Oct.). 



The type is a Tantalus specimen.

Fam. CHERMIDAE. 



( = Psyllidae auctt. et huj. op. in. p. 113.) 

 Dr Perkins' collections from 1892 — 1902 are in the hands, I understand, of 

 Mr E. A. Schwarz. I add only two to my former enumeration, though I took at 

 least ten new species recently during a visit to Kilauea, Hawaii. 



Hevaheva Kirkaldy (huj. op. in. p. 113). 



(i) Hevaheva monticola Kirkaldy. 



Hevaheva vionticola Kirkaldy, 1908, P. H. E. S. i. p. 205. 



I originally described this from a carded pair taken recently by Dr Perkins at an 

 elevation of about 2000 ft. on Tantalus, Oahu. I have since secured a pair taken about 

 the same place by Mr Swezey. 



Hab. Oahu.

Hevaheva silvestris Kirkaldy, 1908, op. cit. p. 206.

 secured another specimen taken at the same place by Mr Swezey.
