48 FAUNA HAWAIIENSIS 



Abdomen in t with pale pubescence, its apical dorsal plate not strongly dilated, 

 erect, clothed along the margins with pale hairs, and armed, on either side, on the 

 margin at the base beneath with a long fine spine, the apex of which is strongly 

 incurved. Apical ventral valve narrow, tongue-like, not closed against the dorsal plate, 

 its surface clothed with long pale hairs. (Plate III. fig. i and Plate IV. figs. 20 

 & 20a;.) 



Length 11 — 14 mm. Expanse 33 — 43 mm. 



Hab. Hawaii ; various localities in dense and damp forests (2000 — 3000 ft.). 



(2) Anomalochrysa molokaiensis, sp. nov. 



Closely allied to the preceding, flavous with a bright sulphur-yellow median 

 longitudinal stripe extending the whole length of the insect. May be distinguished 

 at once from the preceding by the condition of the third cubital cellule, which is of the 

 usual form, the dividing nervule received by the cubitus. 



The wings have no black dots. The nervuration is rather more complex ; there are 

 four rows of cellules and indications of a fifth formed by the gradate nervules in the 

 anterior wings ; four more or less complete rows in the posterior. 



Expanse of $ about 43 mm. 



Hab. Mountains of Molokai (4000 ft.). A single % found drowning in a pool of 

 water. 



(3) Anomalochrysa sylvicola, sp. nov. 



Flavous, with a median longitudinal stripe of a sulphur-yellow colour more or less 

 distinct. 



Allied to the preceding species but smaller, the wings of very similar shape, the 

 posterior pair very distinctly pointed at their apex. Nervuration and hairs pale, but the 

 gradate nervules in the anterior wings are more or less black or blackish, and form 

 evidently four longitudinal rows of cellules with a tendency to a fifth, the intermediate 

 series being more or less irregular ; posterior wings with four, more or less complete, 

 rows, one of these sometimes consisting of but few cellules. In the anterior wings the 

 gradate nervules (except the lowest series slightly), although dark themselves, have not 

 an evident infuscation along their margins. Abdomen clothed with pale hairs, the 

 apical dorsal plate not greatly dilated, formed much as in the preceding. (Plate HI. 

 fig. 2.) 



Expanse 35 — 37 mm. 



Hab. High plateau of Kauai (4000 ft.).
