This comes near the Sapei'da seminigra, Chevrolat, from the 

 Philippine Islands, described in the ' liev. Zool. Cuv./ and be- 

 longs to the genus Isoscelis of Newman, ( Entom/ p. 319. The 

 Saperda elongata, Hope, from Nepal, is closely allied to it.

Note on Fulgora candelaria : — Mr. Bowring, in the letter from 

 which I have quoted before, remarks : u I have been keeping a 

 number of Fulgorce to endeavour to find out if there were any 

 truth in the commonly received idea, that they emit light at night 

 or in the dark. The insect is very common here ; I have seen as 

 many as a score in an evening ; but though I have brought many 

 of them home, I have not been able to discover any luminous pro- 

 perty in them. It would not perhaps be right to say that they 

 do not possess it because I have not seen it, as one well-authen- 

 ticated case would prove the contrary, though in a thousand others 

 no light may have been observed. I find that they become very 

 active and restless towards night-fall, and they fly much better 

 than would be expected from their somewhat clumsy shape. If 

 the rostrum be crushed or bent it soon recovers its original shape, 

 — if the insect be alive I mean." 



Ledropsis. — Head with its prolongation longer than wide, 

 in front of the eyes parallel and as wide as the thorax, then
