286 Louis B. Prout: 



auf breiter Basis tangiert. — Färbung grün mit mehr oder weniger 

 kupferigem Anflug. — L. 5 — 8 mm (s. r.). 



Sämtliche Tiere (ca. 40 Exemplare), stammen aus Taihorin, 

 wo sie im ]\Iai 11)10, im Juni, August und November 1911 von Sauter 

 gefangen wurden. 



Ein einzelnes Stück (ein (^) aus Hoozan — November 1910 — 

 weicht etwas ab, ohne daß es mir festzustellen möglich wäre, ob 

 es sich hier um eine andere Art oder um eine Rasse der vorliegenden 

 Art handelt. Die Deckenskulptur ist ähnlich der des congener Jek., 

 die Fühler sind schlanker als bei formosanns und kurz vor der Mitte 

 des Rüssels eingelenkt; Unterseite und Schildchen bläulich gefärbt. 



H. Sauter's Formosa Geometridae. 

 Supplement. 



By 



Louis B. Prout, F. E. S. 



After I had worked out the major part of the Geometridae 

 of this fine collection (see Ent. Mitt. (Deutsch. Ent. Mus.) III, 

 pp. 236 — 249, 259 — 273), a small amount of further material was 

 received by the Museum, of sufficient importance to call for a 

 supplementary note. 



With regard to my former articles, I must plead guilty to a 

 complete ignorance of the local topography, and in Publishing the 

 Iccalities I merely follow-ed the labeis on the specimens, without 

 comment. According to mv friend Mr. A. E. Wileman, however, 

 Karapin (see N«. 7, 22. 28. 29, 46, 62, 114, 127, 144, 149, 154) 

 and Punkio (not ,,Punkiko", see N'>\ 5, 19, 46, 53, 55, 63, 69, 

 110, 128, 139, 140, 151) belong to Formosa, not to Japan. 



A few synonymic notes and corrections are also desirable. 

 In them and in all additional records cf previously recordcd species 

 I have conserved the sequence and numbering cmploycd in my 

 former articles. The additions are therefore registered as 14 bis, etc. 

 They number 10 in all, bringing up the total for the ccllections 

 to 172. 



Subfam. Oenochrominae. 



1. Heteralex aspersa formosana INIatsumura. — Study of more 

 extensive material convinced me that the light form of H. aspersa 

 constituted a good local race onHainan and Formosa and in 1916 

 I named it subsp. alhescens (Nov. Zool. XXIII, p. 2), with Hainan 

 as type locality. Subsequently I found, however, that Matsumura 

 (Thousand Insects of Japan [!], Supp. 3, p. 36, 1911) had anti- 

 cipated me by naming the insect in question LoxaspUatcs (!)
