^Q FAUNA HAWAIJENSIS 



Length of abdomen 31 — 36 mm. Posterior wing 20*5 — 23 mm. Expanse 

 44 — 49 mm. 



Hab. Mountains of Kauai (4000 ft.). Not noticed at lower altitudes. 



A. leptodevias is closely allied to this species and has very similar ^ characters but 

 the tubercle of the superior appendages of that species inwardly is differently situated, 

 not reaching higher than half the height of the appendage, and the lower appendages 

 extend only about as far back as the superior pair. 



(11) Agrio7t orobates, sp. nov. 



Male of the form, size and colour of the preceding. Superior appendages short, 

 in lateral view shorter than the loth segment, resting on the lower pair, and terminating 

 in a black tubercle. Viewed inwardly, they are much less strongly rounded on the 

 lower margin than is the case with that species, and on this margin towards the base 

 they are armed with an extremely minute black spine, which is not directed upwards 

 to the level of the dorsal margin. Lower appendages long, directed upwards and 

 inwards, their apices meeting in the middle line, each armed with two minute but 

 distinct spines, the inferior rather the stronger. Tenth segment extremely deeply 

 excised, almost to its basal margin. 



A single ? taken in the same locality may belong to this species. It resembles 

 those rnentioned under the preceding in most respects but has the abdomen nearly 

 entirely red, a dorsal longitudinal line on the second segment and the apex of this 

 and the five following segments being black. 



Hab. Mountains of Kauai above Waimea (4000 ft.). A single $ taken in 

 May, 1894. 



(12) Agrion lepiodemas, sp. nov. 



A small and very slender species. Face below the antennae entirely red, vertex 

 of head posteriorly with a red transverse line. Prothorax with the front and hind 

 margin and four spots on the dorsum yellow ; thorax above and at the sides with 

 yellow or red stripes, the median ridge red. Legs red, the spines black. Four basal 

 and three apical segments of the abdomen red, the intermediate ones dark. Thirteen 

 post-cubital cellules in the front, eleven in the hind wings. Three cellules between the 

 quadrilateral and the nodus. Upper side of quadrilateral ^ in the upper wings, in 

 the lower \ the length of the lower side. 



Superior appendages very short, in lateral view hardly half as long as the loth 

 segment, very strongly dilated, almost from the extreme apex, which forms a small
