138 NEUROPTERA. 
1. Neoneura amelia, sp. n. (Tab. V. fig. 36; Tab. VI. fig. 8.) 
&. Dorsal surface of the head, thorax, and first three abdominal segments bright orange-red, with the following 
black markings: often a basal line on the labrum and on the clypeus, a spot on the mandible, an 
anteriorly-trilobed spot on the vertex, the middle lobe of which fills up the space between the ocelli, and 
whose lateral lobes are each prolonged as a fine line to a spot behind each antenna touching the eye- 
margin; posteriorly this trilobed spot is confluent with the black which covers most of the rear of the 
head; a second spot on the vertex touching the eye-margin behind the one already described, and which 
is usually narrowly connected along the eye-margin with the black of the rear of the head ; between this 
spot and the trilobed spot a small subeircular spot, with one or both of which it may be connected * ; a 
mid-dorsal stripe on the anterior prothoracic lobe, a mid-dorsal line and a small spot each side on the 
middle prothoracic lobe, a mid-dorsal thoracic stripe whose edges are somewhat crenate and whose 
anterior end expands into an inverted head of a FT at the anterior mesothoracic border; a humeral stripe 
whose width varies much throughout its course, and which unites below with a variable mesepimeral * 
stripe (each antehumeral orange-red area is about three times as wide as the black mid-dorsal stripe), a 
line on the second lateral thoracic suture, often a metepimeral stripe, a mid-ventral streak behind the 
third legs, a little more than the basal dorsal half of abdominal segment 1, a lateral stripe for the entire 
length of 2 and 3, rings on the intersegmental articulations, almost all of 4-10 (except a narrow, pale 
green or yellow, transverse basal ring on 4-6 or 7 which is confluent with a fine pale mid-dorsal line 
extending for almost the entire Jength of these segments), and the superior surfaces of the femora and of 
the first (and sometimes also the second) tibiae in older individuals. The following parts are yellowish : the 
labium, a pair of spots on the rear of the head near the posterior foramen, a narrow stripe along the eye- 
margins inferiorly, sometimes a pair of very small occipital spots on the black trilobed spot of the vertex, 
sides of the thorax between the black stripes, and the feet, except as above stated. 
Hind margin of the prothorax slightly produced and convex medially, somewhat concave on each side. 
Superior appendages about half as long as 10; viewed from above rather thick, blunt, with a transverse groove 
extending from the ner margin almost to the outer; this groove is in reality a considerable excavation 
on the distal surface of the appendage, as may be seen by viewing it at various angles; below this 
excavation, also on the distal surface, is a second groove running obliquely from the inner margin of the 
appendage upward and outward; the borders of these excavations or grooves are variously tuberculated, 
thus giving the appendage a quite complicated appearance, as shown in our figure. Inferior appendages 
longer than the superiors, but not so long as segment 10, simple, conical, directed upward. 
@. Orange-red of the g replaced by pale greenish-yellow, the following markings black: a basal line on the 
labrum, a spot on each mandible, a pair of spots on the clypeus, the rear of the head superiorly (but not 
below), a pair of spots on the middle prothoracic lobe, a line of interrupted dots and dashes along each 
side of the mid-dorsal thoracic carina, a line on the humeral and second lateral thoracic sutures, a point 
on the middle of the area between the last two, the base of abdominal segment 1 dorsally, a lateral stripe 
each side of 2 and the venter of 2. (The remainder of the abdomen and the feet have been lost.) 
3 9. Wings hyaline, sometimes faintly smoky, arculus usually (67 °/, front wings, 71°5 °/, hind wings) situated 
slightly beyond the second antecubital, but in some specimens either at that vein or distinctly beyond it ; 
inferior sector of the triangle usually arising at the submedian cross-vein (91°5°/, front wings, 74°3 °/, 
hind), or beyond it ; ultra-nodal sector arising 2-5 cells proximal to the inner brace vein of the ptero- 
stigma on the front wings, 2-4 on the hind; postcubitals, front wings, 9-11, mostly 10 (64°3 °/,), hind 
wings 7-9, mostly 8 (57 °/,) in the ¢, 10 in the single 2; pterostigma rhomboidal, brown, surmounting 
slightly less than one cell 7. 
Dimensions.—Abdomen, ¢ 25-27; hind wing, ¢ 16-17, 2 17:5 mm. 
* Two of the Livingston males have the spots on the vertex and the mesepimeral stripe almost entirely 
absent. 
ft In one hind wing (¢ ) the superior sector of the triangle reaches to the vein next distal to that descending 
from the nodus, and between the sector and the hind margin there is an additional cell. In one front 
wing (¢ ) the vein next distal to that descending from the nodus is forked, and the superior sector of the triangle 
reaches to between the two branches of the fork. These abnormalities, and those noted in the footnote to
