Genera and Species of Phytophaga. 229 
Genus Lina, Redt. 
Lina Adamsit. 
Anguste oblonga, convexa, viridi- aut ceruleo-metallica, niti- 
dissima ; abdominis limbo, pedibus, thorace antennisque rufo- 
fulvis, his unguibusque extrorsum nigris; elytris subcrebre 
punctatis, viridi-zeneis aut ceruleis. 
Long. 4—5 lin. 
Hab. Chusan. This beautiful insect was collected in some 
abundance by Messrs. Bowring and A. Adams. After this latter 
gentleman I have named it, as a slight token for his exertions in 
obtaining, and liberality in dispersing, the Phytophagous Coleoptera 
of Japan and Mantchuria. 
In size this species approaches closely to Lina cuprea, but in 
sculpture and form of thorax, viz., in the absence of the thickened 
Jateral border, it resembles Lina enea. The totally different colora- 
tion will easily separate it from either insect. 
Genus PraciopEra, Redt. 
Plagiodera celestina. 
Late ovata, modice convexa, rufo-testacea, nitida; vertice an- 
tennisque extrorsum nigris; elytris tenuiter subcrebre punc- 
tatis, Cuprels. 
Long. 23 lin. 
Hab. Hong Kong. Collected by Mr. Bowring. 
Narrower and more ovate than P. cinctipennis ; the elytra also 
more closely punctured and wanting the pale lateral border. 
Plagiodera cuprea. 
Ovata, valde convexa, cuprea, nitida; thorace disco tenuiter, 
irreculariter, lateribus rude, subcrebre punctato; scutello 
levi; elytris confuse punctatis. 
Long. 43 lin. 
Hab. Lake N’Gami. 
Sides of thorax nearly straight and parallel behind, narrowed
