NEUROPTERA 75 



tooth of the upper appendages is rather less developed in some specimens than others, 

 but there is no constancy in this respect even with examples from the same locality. 

 Some specimens show an evident tendency to the form of nervuration on which the 

 genus Megalagrioii was founded. 



Hab. All the Islands from Oahu to Hawaii inclusive. 



(20) Agrion vagabundum, sp. nov. 



Allied to A. deceptor M'^Lachl., larger specimens of which it sometimes exactly 

 resembles in general appearance. Abdomen usually with the first 6 segments red. 

 Face below the antennae pale, clypeus more or less dark in the %. Post-ocular spots 

 large and connected. Prothorax spotted, thorax with longitudinal latero-dorsal stripes. 

 Legs reddish. Wings usually with 4, sometimes 5, cellules between the quadrilateral 

 and the nodus. Four to six post-pterostigmatic cellules in the posterior wings. Ptero- 

 stigma not brightly coloured. 



Z superior appendages as long or longer than the loth segment, curved inwards 

 but not very strongly, widely dilated on the basal half the inferior margin within 

 bearing a very minute tubercle, sometimes hardly visible, towards the apical angle, 

 which is rounded off No distinct tooth or spine at the inferior apical angle, such as is 

 seen in A. deceptor. Inferior appendages acute, extending rather beyond the dilated 

 portion of the upper ones, curved inwards and upwards. 



% superior appendages red or blackish, valvules pale. (Plate V. figs. 13 & 13a.) 



Length of abdomen 31 — 36 mm. ; hind-wing 23*5 mm. ; expanse 50 mm. 



Hab. Widely distributed on Kauai from 1000 ft. to 4000 ft. or more, in the 

 mountains. 



Some females which certainly belong to this species show hardly any red colour on 

 the abdomen, the variation being much as in A. deceptor, from which the % can hardly 

 be distinguished. 



(21) Agrion kauaiense, sp. nov. 



Face below the antennae red or pale, as also the post-ocular spots which are 

 connected. Prothorax with red or pale spots ; thorax above and at the sides with red 

 or pale lines. Legs red with long black spines. Pterostigma bright red. Abdomen 

 with the basal five segments and the two apical ones (more or less) red ; 6th, 7th and 

 8th black usually, but the 6th sometimes red. First five segments often with a narrow 

 apical black band.
