60. A. POLYSEMA, LOW. 



Hesperilla polysema, Low., T.R.S., p. 311, 1908. 



The <5 of this species is without a stigma, consequently 

 I refer it to Anisynta. This sex differs very little from the 

 9 , excepting that it is slightly smaller (34 mm.), and the 

 small additional neck above vein 1 on under-side is also con- 

 spicuous on upper-side ; there are very faint indications of 

 two or three whitish Hecks on upper side of hindwing (in one 

 specimen tolerably distinct). The row of spots on under side 

 of hindwings are somewhat smaller, and the fifth one, count- 

 ing from the bottom, has a tendency to be geminate. In all 

 probability these characteristics will be en evidence in better 

 and fresher specimens of the 9 • The type from which the 

 original was taken was somewhat imperfect. The species 

 under review does not approach any other known to me, but 

 appears nearest Tasmanicus, Misk. 



Type 9 j i n Coll. Lyell ; type S , in Coll. Lower. 



Port Darwin; and Chillagoe, North Queensland. Two 

 specimens; in February (F. P. Dodd). 



61. A. (?) ARGINA, Pl6tz. 



The reference given to this species is S.E.Z., xliv., p. 

 227, n. 903 (1883). Hesperia argeus, Plotz (Weymer M.S.S.) 

 is on that page, and the number is 704, and as the insects are 

 so widely divergent the reference is probably wrong. I have 

 no copy of S.E.Z. of that date, so am unable to state definitely. 

 Mr. Waterhouse gives "Mittheilungen Verein fur neu Vom- 

 pommern und Rugen in Greifswald (Berlin), p. 22, 1884," as 

 the reference. The description of argina is as follows: — 

 "Fichlerkolbe ( ? Fuhlerkolbe) am Ende stumpf abgerundet. 

 Oberseite schwarzbraun. V fl nur mit den typischen weissen 

 Flecken ; der in der Mittel 3 ist gespalten, der in Z. 1 ist getheilt 

 und grau; in Z. 5 ein Querstrich. H. fl mit 5 grauen Puncten 

 im Bogen hinter der Mitte. Unterseite grau mit braunen 

 Rippen. Vdfl mit den weissen Flecken wie oben, auf der 

 Hinterhalfte braun. H. fl. mit 8 weissen Puncten in | Kreis 

 und einem in der Mitte." 



Herr.-Sch., I.L. 13 mm., Brisbane. 



It is referred to the genus Syrichthus, Bdv. The 

 description, so far as it goes, agrees somewhat with polysema, 

 Low., but the absence of the curved series of 5 grey dots on 

 upper-side of hindwing is a deterrent character. One of 

 my male specimens of polysema has a faint curved series of 

 5 dull whitish dots beyond middle on upper-side of hindwing. 



The drawing of argina before me shows the 5 grey 

 dots, also the divided grey dot in cell 1. And the under-side
