Lucidota ? discicollis. 



Lucernula discicollis, Kiesenw., loc. cit., p. 258. 



Nagasaki ; Kobe ; Kashiwagi ; Nara. 



Neither this nor the following species are typical 

 Lucidota, being more ovate, and having diaphanous 

 patches on the thorax in front. 



Lucidota ? fumosa, n. s. 



Nigro-fumosa, opaca, prothorace antice angustato 

 rotundato, areolis duabus translucidis. 



Fukushima, and Tsukuba-yama. 



Nearly of the same form and characters as L. disci- 

 collis, but the thorax narrows much more in front, and 

 has no discal yellow patch. 



About six specimens were met with. 



[Lucidota tabida, Kiesenw., loc. cit., p. 259.] 



Yokohama. 



I examined the type of this, and believe it is only an 

 immature and discoloured specimen of L. biplagiata, 

 and by no means fitted for a type of such a soft insect. 



Luciola picticollis. 



Luciola picticollis, Kiesenw., loc. cit., p. 262 ; Gorh., 

 Trans. Ent. Soc. Lond., 1880, p. 102.

 taken in July. 



Luciola vitticollis.

 Trans. Ent. Soc. Lond., 1880, p. 108. 



Tokio ; Yuyama ; Hitoyoshi ; Nikko. 



This is the larger species, according to Kiesenwetter's 

 description, and is one of the finest in the genus. The 

 thorax is sometimes without the vitta. 



It occurred in May.
