68 FAUNA HAWAIIENSIS 



thorax are broad and distinct, while the pale marks which border the eyes inwardly 

 are connected by a transverse band just behind the posterior margin of the clypeus. 



The measurements of this species are about as follows : 



Typical form and race waianaeaniim. Length of abdomen 36 — 38 mm.; of post, 

 wings 25 — 27 mm.; expanse 52 — 54 mm. 



Var. from W. Maui. Length of abdomen 42 mm. 



Race peles and var. fallax Length of abdomen 30 mm. ; of post, wings 19 mm. ; 

 expanse 43 mm. 



Hab. Typical specimens from Molokai (3000 — 4000 ft.), and from the lao Valley, 

 Maui. Larger and darker var. from high ridges of W. Maui Mts. (4000 ft.). Race 

 waianaeanum from the Waianae Mts., Oahu {2000 — 3000 ft.). Race peles widely 

 distributed on Hawaii (2000 — 4000 ft.), the var. fallax found with it. 



(8) Agrion eudytum, sp. nov. 



Closely allied to the preceding and very similar in most respects. Black ; ^ with 

 the post-ocular spots, those on the prothorax, the lateral longitudinal lines of the dorsum 

 of the thorax, the greater part of its sides, the first two segments of the abdomen, 

 and the femora beneath pruinose, of a bluish, almost white, colour. Face below the 

 antennae obscurely pallid. 



Female with the face yellow below the antennae, as also the post-ocular spots 

 which are distinct and a line on the posterior margin of the vertex. Prothorax with 

 yellow spots. Thorax with the latero-dorsal lines reaching half-way to the insertion 

 of the wings, its sides for the most part pale. Femora almost entirely pale. Abdomen 

 with the first two segments and base of the third pale at the sides and also partly 

 above. 



Anterior wings with 3 or 4 cellules between the quadrilateral and the nodus, and 

 about 20 post-cubitals. Upper side of quadrilateral very short ; one-fourth as long as 

 the lower in the anterior, one-third the length of the lower, in the posterior wings. 



^ superior appendages as long as the loth segment, pale inwardly on the basal 

 portion, formed very like those of A. amaurodyhim, but more dilated, the inferior 

 apical spine evidently smaller, between which and the base, on the inferior margin of 

 the appendage there is a minute black tubercle. Inferior appendages black, pale at 

 the base, curved upwards, the narrow apical portion longer than in the preceding 

 species and much less strongly bent inwards. 



% superior appendages black, valvules and their appendages pale. 



Hab. Kauai (about 1000 ft.), i ^, i $ taken. Probably not rare as I spent 

 only an hour or so in the locality and did not revisit it.
