206 . HETEROCERA. 
2. Arrhenophanes volcanica, sp.n. (Tab. VII. fig. 2.) . 
Antennae g strongly serrate and minutely ciliate, but not bipectinate; 9 bipectinate 5-6, with closely- 
packed broad pectinations; ochreous. Palpi short, rough, slightly recurved, terminal joint shorter than 
median; whitish ochreous, smeared with brownish fuscous above. Heud rough ; ochreous. Thorax 
covered with long upstanding spatulate hair-scales ; whitish ochreous, tipped with dark brown posteriorly. 
Forewings with the costa raised near the base, and again near the middle, apex depressed, rounded, termen 
somewhat oblique, slightly concave, very broad; whitish ochreous, with a golden silky gloss, especially 
on the apical portion of the cell, semitransparent from a little before the middle to its outer extremity, 
presenting in different lights the appearance of a large patch of shining pale straw-yellow, or pale 
greenish grey, with iridescent lustre; this patch is terminated by a dark um ber-brown. line which 
separates it from a broad band of rich golden buff-brownish, in varying shades, having the lustre of silk 
plush ; the band passes round the outer extremity of the transparent patch, and becoming wider beiow, 
follows its lower margin to the middle, where it is separated by a wedge-shaped streak of bright iridescent 
lilac from a coarsely scaled mat of shining pinkish brown, extending to the middle of the dorsum, 
but fading inward into the paler, or more whitish ochreous basal third of the wing, which is entirely 
clothed with strong upstanding spatulate scales; a narrow dark brown line defines the outer margin 
of the large white ocelloid median pattern, but does not extend above vein 8; between veins 5 and 6 
is a small dark brown terminal spot; cilia shining, pale golden ochreous. Eep.al. ¢ 34, 9 40 mm. 
Hindwings 1; in colour almost the exact counterpart of the forewings, with the exception that 
the semitransparent discal patch is less conspicuous; the plush-like golden buff markings are more 
diffused outward over the wing-surface, containing two brighter golden spots and traversed by 
four or five shorter slender transverse dark brown lines; the brown marginal spot is also present, 
and another appears near the flexus, while the cilia are slightly mixed with dark brown in the same 
direction, Abdomen 2 whitish ochreous, anal tuft ochreous; ovipositor broad, rather obtuse, bent 
under the body: ¢ with the anal claspers long and narrow, uncus slender and slightly bent over. Legs 
whitish ochreous. 
Type Q (66457, Chiriqui); 3 (66456, Cerro Zunil) Mus. Wism. (Godm-Salv. Coll.) BM. 
Hab. Central America—GUATEMALA: QUEZALTENANGO: Cerro Zunil, 4000-5000 ft., 
VITI-IX. 1880 (G. C. Champion)—Panama: cutriqui1: Volcan de Chiriqui, 2000- 
3000 ft., 1881-2 (G. C. Champion). ‘Two specimens. 
The ¢ is only about two-thirds the size of the 9°. 
Fam. 10. SPARGANOTHIDAKE, fam. n. 
Type: Srareanornis Hb. (pilleriana S-D.). 
To include a series of genera having FW: 7-8 stalked (or coincident), and HW: 
cubitus pectinate, or impectinate. 
| AESIOCOPA Z. 
Type: Tortrix (Aesiocopa) vacivana Z. (Z. 1877). 
Axsrocora Z. Hor. Soc. Ent. Ross. 13 106-8 (1877) ; Frnld. Gn. Tortr. 41, 60 (1908). 
This genus agrees with Homona Wkr. in the structure of the palpi and in the 
neuration (FW: 12 veins; 7—8 stalked, 7 to termen; rest separate. HW: 8 veins; 
6-7 stalked ; 3-4 connate), but the cubitus of the hindwings is pectinate.
