Neuroptera of the Hawatian Islands. 301 
basal joint of antenne: strongly bulbose; claws dilated inter- 
nally at the base. 
Abdomen apparently having a blackish band on either side, 
in which are yellow (or greenish) spots ; clothed with rather 
long, but not dense, hairs. In the male it is terminated by a 
broad oval superior plate, concave beneath, and ventrally by 
a much shorter nearly semicircular plate. 
Wings vitreous, slightly iridescent, ovate, subobtuse ; neu- 
ration strong, open ; longitudinal nervures greenish, transverse 
and gradate nervules mostly blackish, the costal nervules pale 
at either end, the whole set with rather long black hairs; 
pterostigmatic region elongate (very long and somewhat dilated 
in posterior wings of male), greenish; subcosta becoming 
confluent with the costa before the apex; partition nervule of 
the third cubital cell extending beyond the nervule above it 
(the cellule oval) ; six and eight nervules in the two gradate 
series in the anterior wings of male, and four and five (or six) 
in those of the female (in the pair before me); fifteen to 
seventeen antepterostigmatic nervules. 
Length of body 6 millim.; expanse, g 20 millim., 9 
22 millim. 
One of the smallest species and, in some respects, aberrant, 
the condition of the subcosta showing analogy with Hypo- 
chrysa, and the formation of the apex of the abdomen with 
Anomalochrysa; but as there are only two series of gradate 
nervules it cannot be located in the latter genus.

Violentus is the form in which the dark streak in the 
apex of the posterior wings is absent. One of Mr. Black-
