20 FAUNA HAWAIIENSIS 



( 1 1 ) Paratrigonidium robustuni, sp. nov. 



Forma et colore fere praecedentis, sed major et cercis evidenter longioribus 

 distinguendus. ^. 



Long, corporis 9 mm. ; pronoti i '6 mm. ; tegminum 6 mm. — Lat. tegminum 

 3'5 mm. — Long, femorum post. 6 mm.; cercorum 4'6 mm. 



Very like the preceding species but decidedly larger and with longer cerci. The 

 species is altogether more robust than most others of the genus. The black area 

 behind the vena stridulans well-marked, and rugulose as in the preceding. 



Hab. Kauai (4000 ft.); i ,^ taken from beneath the bark of a tree. 



(12) Paratrigonidiiiin molokaiense, sp. nov. 



Testaceum, fronte inter antennas tota nigra. Clypeus totus vel ex majore parte 

 niger. Articulus antennarum primus et secundus nigri vel picei. Pronotum cum 

 capite inter setas distincte pallide pubescens. Femora omnia cum tibiis distinctissime 

 nigro-notata ; femora postica notis minimis compluribus nigris intus ornata. Tegmen J 

 dextrum plaga post venam stridulantem nigra, tota rugosa, maculisque compluribus 

 postice, necnon in campo laterali, signatum. Tegmina % supra pallida, campo laterali 

 toto nigricante. Cerci pallidi, minus longi. 1; %. 



Long, corporis J' 8, ? 7 mm.; pronoti $ 1-4, % 1-4 mm. ; tegminum ^ 5'5, 

 % 4"5 mm — Lat. tegminum ^ 3"2 mm. — Long, femorum post. ^ 5*2, % 5"2 mm.; 

 ovipositoris 27 mm.; cercorum % 3'2 mm. 



Certainly a distinct species, the hind femora (at least in the ^) rather more 

 strongly clavate, than in most of the genus. 



Hab. Mountains of Molokai (3000 ft.); rare, i ^ i ? taken amongst low vege- 

 tation.

Pallide testaceum, angustum, elongatum, femoribus omnibus nigro-notatis. Teg-
