tyiua] ARCTIADAE 



15. Tyria, lib. 



Head with loosely appressed hairs. Ocelli large. Antennae 

 in (J ciliated, with longer setae at joints. Palpi short, por- 

 rected, rongh-scalcd. Thorax hairy beneath. Abdomen 

 smooth-scaled. Femora somewhat hairy, tibiae smooth-scaled. 

 Forewings : 6 sometimes out of 9, 7 and 8 out of 9, 10 out 

 of 9, 11 connected with 9. Hindwings: 3, 4, 5 rather approxi- 

 mated, 6 and 7 connate or short-stalked, 8 from middle of cell. 



Only one species is known. Larva with scanty hairs. This 

 and the following genus are allied to the extensive Indo-Malayan 

 genus Nyctemera, ranging to S. Africa and New Zealand. 



1. T. jacobaeae, L. 35-44 mm. Head, thorax, and abdomen 

 black. Forewings blackish-grey ; a crimson subcostal streak 

 from base to £, extremity expanded ; a crimson dorsal streak 

 from base to § ; a crimson terminal spot below apex, and 

 another above tornus. Hindwings crimson; a costal streak, 

 middle of terminal edge, and cilia blackish-grey. 



Britain to Caledonian Canal, Ireland, common, scarce north 

 of the Clyde ; Europe, WC. Asia ; 5, 6. Larva orange, hairs 

 black ; each segment with a thick black ring ; head black : on 

 Senecio jacobaea and S. vulgaris ; 7, 8. The conspicuous larval 

 colouring is a warning-signal, the larva being uneatable. 



1G. Utbtubisa, Hb. 



Head smooth. Ocelli large. Antennae in $ ciliated, with 

 longer setae at joints. Palpi moderate, ascending, with loosely 

 appressed scales. Thorax smooth beneath. Abdomen smooth- 

 scaled. Tibiae smooth-scaled, spurs very short. Forewings : 

 7 and 8 out of 9, 10 connected with 9. Hindwings: 3, 4, 5 

 rather approximated, 6 and 7 connate or short-stalked, 8 from 

 middle of cell. 



A small genus, inhabiting the warmer regions of the world ; 

 only one species reaches Europe. Larva with rather scanty 

 hairs, some finely branched. 



1. U. pulchella, L. 28-38 mm. Head and thorax whitish, 

 black-dotted, often orange-marked. Forewings ochreous-
