TACHYPHYLE. By L. B. Prout.

apex sometimes subfalcate. Hindwing with humeral angle more expanded than in Tachychlora, the frenulum 
of the $ wanting or vestigial; abdominal margin long, distal margin also in the more typical species long and 
straightish; coloration generally simple. Of the early stages little is known; see T. pigraria and olivia. Ex¬ 
clusively Neotropical. 
T. oubrica Dyar. “Green, the markings faint; discal dots minute, black; outer line pale, dark within, oubrica. 
much as in bryata Feld (6 h). Hindwing with a large square light purple patch at anal angle, reaching from outer 
line to margin. Expanse 22 mm.” Panama Canal Zone: Trinidad River, March 1912, 1 
T. pigraria Wickers & Scheller (5 d) has never been matched in my experience and I formerly regarded pigraria. 
it as a lost Phrudocentra. But after a careful study together with the $ type of the following I have little doubt 
that it will prove a very close relative, or probably an aberrant form (perhaps crudely figured) of the same, 
with more green at the base of the forewing. The antenna is only figured as serrate, but in basiplaga $ the 
pectinations are not quite as long as the diameter of the shaft. Hindwing beneath perhaps greener distally 
than in basiplaga. Larva extremely sluggish, brown, protectively resembling a withered leaf, the first 5 ab¬ 
dominal segments with enormously large dorsolateral processes which form, viewed from above, a continuous 
plate. On a parasitic plant called “Vogelgagga”. Surinam. 
T. basiplaga Walk. (5 d) differs from the similarly shaped species in the reddish basal patch of the basiplaga. 
forewing. $ larger and less long-winged than J (compare pigraria). Described from Brazil, but extends to 
French Guiana and Costa Rica. 
T. hamata Schaus (5 d). Rather large, shape very extreme, the forewing falcate, the hindwing produced hamata. 
anally as in albiparsa (5 e). Forewing somewhat suffused and striated with olive-brown, hindwing brighter grey; 
the postmedian line broad, bandlike, purple-brown, running from an apical shade on forewing to before middle 
of abdominal margin of hindwing. Costa Rica: Tuis, only the type known. 
T. maiester Dyar must be close to liamata (5 d), if not a form of the same. Shape similarly extreme, maiester. 
Expanse 27 mm. ‘Torewing dark green, the apex red-brown, the extreme costa and tip black; some blackish 
freckles along costal half; discal dot rounded, purplish; outer line broad, purplish over white, joining the costa 
near apex. Hindwing green, the line slightly beyond the minute discal dot.” Panama Canal Zone: Porto Bello, 
1 <J, April 1912. 
T. apicibadia sp. n. (5 d) show r s also the extreme shape. 28 mm, $ 37. ForeAving with the black apicibadia. 
cell-dot ringed with brown; weak brown strigulae in anterior half, condensing into a conspicuous spot in the 
apex; postmedian rather broader than in acuta ; a weak antemedian, angled outward at both folds, q hindtibia 
not dilated. $ antenna minutely pectinate to about the 16th segment. Gorgona Island, Colombia, 200 feet, 
at light, 3 July and 20 November 1924 (C. L. C’ollenette, St. George Expedition), 2 1 <j>, in Brit. Mus. 
T. olivia Schaus (5 e) differs from acuta in the less acute forewdng and more rounded hindwing. Face olivia. 
green, mixed with white. Hindtibia of $ not dilated. Larva light fleshy brown, with very large leaf-like 
lateral processes on the first 5 abdominal segments and resting in a curled attitude which gives it a striking 
resemblance to a withered leaf; no doubt nearly related to that of pigraria. S. E. Brazil. 
T. acuta Bull. (5e) is the type of the genus and characteristically shaped, though not so extreme as acuta. 
some of its nearest allies. The face, in fresh specimens, is coloured as in olivia. Hindtibia of $ somewhat dilated, 
with a slender hair-pencil. Varies little, except in size, but the antemedian line of the forewing may be either 
present (though never strong) or obsolete. — aganapla Dyar, founded on a $ from Misantla, Mexico, seems aganapla. 
to be merely a large specimen, with the line on the hindwing a little broadened, appreciably dark-edged proxirn- 
ally. — Eor the rest, acuta is distributed from Panama to French Guiana and the Amazons, the last-named 
being the type locality. Also known from S. Brazil. 
T. antimima sp. n. (5 e). 28—30 mm, £ 32—34 mm. The is scarcely distinguishable from large antimima. 
specimens of acuta (5 d) except that the palpus is scarcely or not at all blackened and the apex of the fore wing 
is more falcate, almost as in allineata. The which we figure, is recognizable at once by having the antenna 
pectinate, with the longest branches 2—3 times as long as the diameter of the shaft. Carabaya, S. E. Peru, 
2000—3400 feet (G. Ockenden), the type series from La Oroya, 3100 feet. 
T. allineata Warr. (5 e). At first sight confusingly similar to acuta , though on an average smaller, allineata. 
Forewing appreciably more falcate. <$ with the pectinations and the hindtibial dilation a little heavier. Wings 
slightly less opaque, less clear green, especially in median area, the lines slender, perhaps a little less white, 
the antemedian of the forewing sometimes better expressed, the postmedian slightly less straight, more diffused 
on its proximal side and becoming obsolete considerably before reaching apex. Venezuela and distributed to 
Colombia, French Guiana and the Amazon.
