being of the width of the upper plate and its apex much 

 narrower, strongly rounded and turned upward to meet the 

 apex of the dorsal plate. Between the two plates (but not 

 protruding from them) a blackish organ can be perceived, but 

 it is too completely folded between the plates for its form to 

 be ascertained. 



Wings of the appearance of thin plates of ivory, white, with 

 a strong greenish opaline lustre. Neuration nearly of the 

 same colour, and therefore not conspicuous. The neuration 

 is furnished, as in A. hepatica, McLachl., with rather long 

 hairs, which, however, are of an obscure colour and excessively 

 fine. The neuration does not appear to me to differ noticeably 

 from that of A. lieijatica, but, owing to its colour, it is difficult 

 to make out. There are evidently five series of gradate ner- 

 vules, of which the first consists of nearly twenty and the fifth 

 of about ten nervules (the intermediate ones being much con- 

 fused), and there are upwards of thirty antepterostigmatic 

 costal nervules. The wings are somewhat more pointed than 

 those oiA. hepatica^ and the posterior pair are evidently broader 

 in proportion.

1 took two specimens of this remarkable insect on Mauna 

 Loa, Hawaii, flying by day at an elevation of about 6000 feet, 

 in May 1882. 



Anomaluchrysa viontanaj sp. nov. 



Body, legs, palpi, and antennoj testaceous ; pronotum and 

 thorax with a brilliant longitudinal scarlet line ; head more 

 or less sufi'used with red. Basal joint of antenna3 strongly 

 bulbose. 



Pronotum longer than broad, narrowed anteriorly, with a 

 transverse impression near base. 



Hind body of male clothed with hairs ; the last segment is 

 in the form of a plate, which is placed upright at a right angle, 

 or nearly so, to the hind body (it is possible that this plate 

 may have been contorted at the death of the insect into the 

 position described, though it is so in all my six male speci- 

 mens). The plate is of an oval shape and is concave on both 

 sides, owing to its much thickened margin. The ventral 

 plate corresponding is triangular and a little turned upwards 

 at the apex. 



The wings are vitreous, with an opaline lustre and well- 

 defined neuration 5 the nervures are all of a greenish colour 

 and are set with long black hairs ; the pterostigmatic region is 

 obscurely greenish. There are three series of gradate ner-
