2. H. fuciformis, L. 42-48 mm. Differs from H. bombylifor- 

 mis as follows : central band of abdomen dark red-brown ; fore- 

 wings with a dark red-brown discal mark, terminal fascia rather 

 broad, moderately narrowed beneath; hindwings with a moderate 

 dark red-brown terminal fascia. 



Britain to Sutherland, rather common ; Europe, WC. Asia ; 

 5, 6. Larva green, yellowish -dotted; lateral line yellowish; 

 5-12 with brown-red spiracular dots or marks, and whitish 

 adjacent dots ; horn red-brown : on Lonicera ; 7, 8. 



2. MACROGLOSSA, Sc. 



Tongue strongly developed. Antennae over ^, gradually 

 thickened to near apex, then pointed, apex slender, hooked. 

 Abdomen broad, smooth, with broad truncate expansible anal 

 tuft, last three segments with expansible lateral tufts. Tibiae 

 hairy. Wings wholly scaled. 



A genus of some extent, nearly cosmopolitan. Imago day- 

 flying, feeding on the wing. 



1. M. stellatarum, L. 45-51 mm. Abdomen fuscous, with 

 white median and black posterior lateral spots, tufts black, 

 Forewings fuscous, with indistinct darker striae; first and 

 second lines black, second angulated above middle, indistinct 

 beneath ; a black discal dot. Hindwings deep orange ; base 

 fuscous ; a red-brown terminal fascia, narrowed and not reach- 

 ing tornus ; termen dark fuscous. 



Britain to the Orkneys, Ireland, common, uncertain in 

 appearance ; Europe, N. and C. Asia, N. Africa ; 9-5. Larva 

 varying from green to brown, white-dotted ; dorsal line darker; 

 lateral whitish ; subspiracular yellowish ; horn bluish, tip 

 yellowish : on Galium ; 7-9. 



3. DEILEPHILA, 0. 



Tongue strongly developed. Antennae less than J, gradually 

 thickened to near apex, then pointed, apex slender, hooked. 

 Abdomen smooth, broad, conical, pointed. Tibiae with ap- 

 pressed scales. 



The genus is large and nearly cosmopolitan, but especially in 

 warm regions. Imago flying at dusk, feeding on the wing. 

 Most of the species occurring in Britain are probably only 

 occasional immigrants, which under favourable circumstances 

 breed here and establish themselves for a year or two.
