408 LANTERN-FLIES. 



named Fidgora (Hotinus) Sultana* The form of the 

 beak, or rostrum, is intermediate between that of H. 

 clavatus and H. pyrorhynchus, and like the upper surface 

 of the thorax, is of a rich blood-red colour ; the elytra 

 are blackish, brown at the base, with the tip ochraceous, 

 and traversed by numerous veins of the same colour ; the 

 wings are of a deep carmine, fading to pink towards the 

 anal angle, the tips being brown, with four or five 

 roundish white spots. The body above is straw-coloured, 

 and, when the insect was alive, was covered with a white 

 mealy substance, which I have noticed on many other 

 insects in the tropics. This showy-looking addition to 

 our known Lantern-Flies remains in a torpid state during 

 the day, and becomes more active in the evening ; in this 

 respect being analogous to its consimilar genera Aphenia, 

 Flata, Ptfciloptera, and Euriptera, which generally select 

 the early part of the night for their Sittings. None 

 of these insects, according to my observation, are lumi- 

 nous in the slightest degree ; I have kept the Hotinus 

 Sultana, and the common Chinese species, for many 

 days, but have never seen the vestige of any luminous 

 property, either about their so-called lanterns, or else- 

 where. Madame Merian has stated, however, that the 

 Surinam species is luminous. 



I have figured a very lovely unpublished species of 

 Flata, which I procured in the jungle immediately 

 behind the village of Ambong, the elytra of which are of 

 a light semi-transparent sepia, with a darker brown circle 

 and a broad diagonal white linear mark, and yellowish 

 tips ; the wings are of a light, silvery, semi-opaque
