EMMILTIS; ANTHOMETRA. By L. B. Prout. ' 87 



with very short pectinations, bearing fascicles of cilia. Hindtibia in ^ with two spurs. Abdomen in cJ rather 

 long and pointed. Forewing with costal margin arched, distal margin very little oblique, neuration about as 

 in Acidalia. Hindwing relatively rather large, costal vein anastomosing as usual near base, but thence only 

 gradually or quite moderately diverging ; second subcostal from angle of cell or very shortly stalked. 



Probably nearest to Oar, notwithstanding the difference in shape and markings. The $ is exces.sively 

 scarce, and imperfectly known. The only two of which I have any knowledge are in the Pungeler collec- 

 tion and very unfortunately both have the hindlegs lost or damaged. I conjecture that she will have four 

 spurs. But even in that case the less abnormal palpus will help to distinguish the genus from Oar. The $ is 

 smaller than the (J, with narrower, more pointed wings and probably flies but little. 



Of this genus also only a single variable species is known. It inhabits the mountains of Central 

 Asia. A species from Panama, described by Thierry-Mieg as Stigma isthmensis, is unknown to me, but will 

 without doubt prove to belong to some other genus. 



S. kuldschaensis Alph. (5 g) cannot possibly be mistaken for any other known species. The wings kuldscluien- 

 both above and below are brownish black with a moderate-sized yellow discal spot. In the $ this spot is ***■ 

 smaller. Discovered in the neighbourhood of Kuldja and apparently common in the Western Thian-Shan. 

 Flies freely by day, from the end of May onwards. — negrita Th.-Mieg (= atraria Bang-Haas) is evidently negrila. 

 only a variety, or possibly aberration of kuldschaensis and was described as such by Thierry-Mieg from Issyk- 

 Kul, while Bang-Haas, who re-described it a year later, regarded it as a species. It is of a deeper black and 

 lacks the yellow central spot. My single specimen is also a little larger than the type-form, and this is also 

 mentioned in the original description. The only known $ has very small yellow spots persisting, so that the 

 distinction seems only to apply absolutely to the ,^(^. The localities known to me are Issyk-Kul and the Alex- 

 ander Mountains, thus a little further west than the headquarters of the tyjie form. 



17. Genus: Knmiiltl.s Hbn. 



Face smooth. Eye small. Palpus rather short, with projecting hairs beneath but these very much 

 more shortly than in Oar. Tongue slender. Antenna in (J pectinate. Hindtibia in both sexes with a single 

 pair of spurs. Neuration of forewing as in Acidalia. Hindwing with second subcostal stalked. 



This and the succeding genera, like the three which precede, are small Palearctic offshoots of the 

 main Acidaliid stock; but they show a higher grade of specialization in the loss of the middle spurs of the 

 $. Emmiltis may be derived from Oar, which it somewhat resembles in shape and pattern, though much inferior 

 in size. The North American species which is referred here by Hulst, sparsaria Walk., is not congeneric. 

 It is necessary to add that of recent yeai's Hubner's name Emmiltis has been mis-applied by some systematists, 

 being used in place of Acidalia Tr. The type of the genus Emmiltis is pygmaearia Hbn., Herrich-Schaffer 

 having long ago restricted it to that species. 



E. pygmaearia Hbn. (= parvularia Hbn.) (4 a). Brownish grey, sometimes tinged with olivsLceons, pyontaearm. 

 sometimes more ochreous, the $ nearly always less bright than the ^. Forewing with an undulate white inner 

 line, usually followed in the (J by a narrow dark band or thick line; the distal part of this band represents 

 the median shade and is closely followed by the black discal dot; to this follows a less undulate, sometimes 

 nearly straight, fine dark postmedian line, edged distally by a thicker pale line; the pale sub terminal line 

 is placed and shaped nearly as in pratana, the area between this and the pale postmedian line is moderately 

 dark; the fringe is long, and is traversed by a thick dark line, which is sometimes expanded int}0 spots opposite 

 the ends of the veins. Hindwing similar, without the inner line. Under surface similar. Moderately variable 

 but always unmistakable. The line or band proximally to the postmedian line is always rather pale, sometimes 

 as pale as the line distally to it ; in this case the wings present the appearance of being traversed by a modera- 

 tely broad pale postmedian band, bisected by the fine dark postmedian line. The geographical range of 

 E. pygmaearia apparently only extends from Southern Switzerland southwards to Central Italy and south- 

 east to Dalmatia. It is on the wing from the end of May into July. The egg is- yellowish, spherical, apparently 

 not fully described. The larva is quite similar to those of Ptychopoda, of medium thickness, tapermg anteriorly, 

 strongly carinated laterally, the head small, flattened. Blackish, tinged with green; dorsal line fine, pale, 

 not interrupted, edged with brown; subdorsal brown, interrupted; spiracles large and black. Polyphagous, 

 preferring dry leaves. 



18. Genus: Anthoiiietra Bdv. 

 Agrees closely in structure with Emmiltis, to which Meyrick has sunk it. But even if there were
