156 NEUROPTERA. 
with black, second pale antehumeral stripe represented only by a 
superior spot, costa yellow anteriorly ; abdomen 44, hind wing 837 mm. 7. bifasciata. 
EE. Face and labrum with no dark markings, sides of thorax with three pale 
stripes distributed as in suasa, costa yellow anteriorly, second pale ante- 
humeral stripe complete; abdomen 46-49, hind wing 37-42 mm. . . [stigmata.] 
The females of G. obscura, Kirby, and tenwis, Hagen, have been omitted from this 
key as I have not seen them; both probably belong to the same group as producta. 
The female of volsella is unknown. 
1. Gomphoides volsella, sp.n. (Tab. VII. figg. 10, 10 @, 13, 14.) 
&. Face and labrum bluish-olive, free margin of labrum bordered with pale brown, vertex and occiput darker, 
obscure, hind margin of latter slightly bilobed, rear of head and labrum obscure brownish-yellow. 
Prothorax chiefly green, a pair of dorsal brown spots. 
Thorax predominantly green, the following stripes dark brown: mid-dorsal, antehumeral, humeral, one on 
first lateral and one on second lateral sutures ; mid-dorsal brown stripe widest at mid-length ; pale green 
area between mid-dorsal and antehumeral brown stripes much wider anteriorly (15 mm.) than posteriorly 
(‘5 mm.), that between humeral and antehumeral brown stripes narrower than they are; brown stripes on 
the lateral sutures narrow, ill-defined. 
Abdomen dark brown to black, the following pale green or yellow: all of segment 1, most of 2 except a dark 
brown band on each side of dorsum leaving between them a mid-dorsal green stripe as long as the 
segment, basal third on 3 and 6, basal sixth on 4 and 5, basal half on 7, prolonged as a narrow mid- 
dorsal stripe on 3-5 almost to their apices, a band on the dilated inferior lateral margins of 8 and 9, 
perhaps a mid-dorsal basal spot on 8. (Fig. 14 shows the inferior margin of segment 9 too straight ; it 
should be convex.) 
Femora pale brown (or green ?), darker posteriorly ; tibiz and tarsi black. 
Wings with a faint yellowish tinge at extreme base not reaching as far as the basal subcostal cross-vein. 
Dimensions and other details are given on p. 154 and in the figures. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith: 1 ¢). 
This male, taken in April, bears considerable resemblance to a number of South- 
American species described under Cyclophylla, but appears to differ from all in the 
shape of the appendages. 
2. Gomphoides elongata. 
Cyclophylla elongata, Selys, Monogr. Gomph. p. 224, t. 12. fig. 5 (term. abd. segs. g') (1858)’; Bull. 
Acad. Belg. (2) vii. p. 546 [20] (1859)*; Calvert, Proc. Calif. Acad. Sci. (3), Zool. i. p. 384

Gomphoides elongata, Hagen, Syn. Neur. N. Am. p. 113 (1861) *. 
3. As compared with the most detailed description ', the Tepic male shows no dark colour on the labrum, 
those from Guadalajara have brown on this part forming the pattern described as black. Pale bands 
on the thorax yellow instead of olive (Guadalajara 3 3); first two lateral stripes as wide as, the last or 
metepimeral wider than, the dark areas separating them, the metepimeral terminal with no dark colour 
posterior to it (Guadalajara 5 ¢, Tepic ¢). ‘“Appendice inférieur rudimentaire ” not consisting of 
*“‘ deux petites lames aplaties contigués”', but of a single piece notched at the tip and overlying the two 
anal valves, or sternites of the eleventh segment, which are probably Selys’s “ deux lames.” Discoidal 
triangle of front wings 2-celled (Guadalajara, 1 ¢ symmetrically, 1 ¢ asymmetrically), internal triangle 
of hind wings 3-celled (Guadalajara, 2 ¢ asymmetrically). 
2 (not hitherto described). Coloured much as the male described’, except for the differences above noted.
