The headquarters of this cosmopohtan genus are in Central 

 and South America. 



The Austrahan species of Tctii^^oma are readily separable by 

 color and size: 



1. Length more than 15 mill 7 cocnilcsccns { l-'abr.) 



I a. Length under 15 mill 2 



2. (jround color pale 3 



2a. Ground color dark 7 



J. Ground color distinctly yellowish 4 



3a. (iround color pale greenish-grey, or greyish-white, or 



pale cinereous 6 



4. Tegmina immaculate 5 



4a. Claval commissure blackish-brown. .. .4 partliaon sp. nov. 



5. X'ertex 4 times as broad as long. (sec. Walker) 



8 quad rata (Walker) 



5a. X'ertex not more than one-half wider than long 



3 pasiphac sp. nov. 



6. A central dark longitudinal stripe down the head, pro- 



notum, scutellum and commissure. .2 pcrkiiisi sp. nov. 

 6a. Above mentioned stripe absent 1 albida (Walker). 



7. Black with orange red markings 6 ancuwlua sp. nov. 



7a. Dark metallic bluish-green with ochraceous markings. 



5 pettimohia sp. nov. 



\. B. 9 albomargiiiafa (Sign.) not included. 



I. albida (Walker.) 



Tct/igonia albida. Walker, 1851, List. Horn., 767, (nee. Walker, 



777)' Signoret, 1853, Ann. Soc. Ent., France, (3} I, 663, 



PI. 21 f. 3; Melichar, 1903, Hom. Ceylon, 157 (*). 



This species varies a little in size and pattern. (3ne example 



in my collection, from Ceylon, has a typical right clavus, but in 



t^he left, the axillary vein joins the middle of the anal vein. 



Hab: Queensland, Cairns (vii-viii), Nelson (vii) and Bunda- 

 berg (ix-xii) on sugar cane and various grasses; also occurs in 

 Ceylon (my collection), Bombay (Melichar), Celebes (Breddin). 

 Philippines (Stal). West and South Africa (Stal), and Mada- 

 gascar (my collection). 



kocbclei, sp. nov. 



Slender; pale testaceous; margin connecting vertex and irons 



* This is not. as Melichar states (1. c.—)/a///da Waiker 776, which on the contrary= 

 alUda Walker Tu—nigri/ascia Walker, an American speces. The Sicilian var. pallida 

 Wrtlker (781) of Aglena omata requires a new name, for which I propose omatula.
