228 Mr. J.8. Baly’s Descriptions of uncharacterized 
mela gibbosa, but the punctures in the present species are much 
smaller and also closer than in that insect; on the side just below 
the shoulder is a large deep somewhat transverse excavation. 
Genus GontocTEenA, Redt. 
Gonioctena Murray. 
Oblonga, valde convexa, subparallela, fulva, nitida; mandibularum 
apice oculisque nigris ; elytris castaneis, confuse punctatis. 
Long. 3 lin. 
Hab. Old Calabar. 
Head somewhat closely punctured ; thorax twice as broad at the 
base as long, sides rounded and narrowed from base to apex ; 
apical margin obsoletely bisinuate ; upper surface subremotely but 
listinctly punctured. Scutellum semirotundate. Elytra irregu- 
Jarly punctured. 
¢ 
Gonioctena Fortunei. 
Breviter oblongo-ovata, convexa, pallide fulva, nitida ; oculis 
mandibularumque apice nigris; thoracis maculis duabus 
elytrorumque singulorum maculis sex, piceis; elytris punctato- 
striatis, interspatiis subcrebre punctatis. 
Long. 23 lin. 
Hab. Northern China. 
Very nearly allied to Gonioctena nigroplagiata, but separated 
from that insect, in addition to the different number of spots on 
the elytra, by its shorter form, its pale scutellum, and more 
coarsely-punctured elytra. 
Genus Gastrozina, Baly. 
Gastrolina thoracica. 
Oblonga, depressa, zeneo-nigra, nitida; thoracis Jateribus flavis ; 
elytris fortiter subcrebre punctatis, interdum obsolete cos- 
tatis, nigro-czruleis aut purpureis, margine elevato levi, 
aeneo-nigro ; abdominis apice piceo. 
Long. 33 lin. 
Hab. Japan. 
This pretty species is perhaps only a local variety of Gastrolina 
depressa: it differs chiefly in the coloration of the thorax, which 
is in the present insect brassy-black with broad lateral margins ; 
this character is constant, without the slightest attempt at variation. 
The raised vittze, always more or less visible on the elytra of G. 
depressa, are usually obsolete in the present species.
