On account of the closed coxal cavities I have placed this 
species in Diorhabda Weise with the characters of which it 
seems nearly to agree. 
96. Mimastra rugosa, n. sp. 
Testaceous; antennae, tibiae and the abdomen fuscous; elytra 
metallic green, finely rugose and punctate. 
Length 3 lines. 
Head impunctate, testaceous; the frontal tubercles strongly 
raised, trigonate, bounded behind by a deep groove; eyes large; 
antennae piceous, the second joint less than half the length of 
the third, the fourth much longer than the preceding, the ter- 
minal joints wanting ; thorax twice as broad as long, the disc 
with a deep transverse groove, impunctate, testaceous, shining, 
the sides nearly straight; scutellum testaceous; elytra narrowly 
parallel, metallic green, closely rugose and wrinkled, the inter- 
stices closely punctured; legs slender, testaceous; tibiae unarmed, 
fuscous like the tarsi, the posterior first joint of the latter, as 
long as the three following joints together; claws appendiculate ; 
anterior coxal cavities closed. 
Hab. Java, Tcibodas (Beccari). 
97. Mimastra semimarginata, n. sp. 
Elongate, parallel, pale testaceous, the extreme base of the 
head, the breast and abdomen, the upper side of the femora 
and the tibiae and tarsi black; elytra closely semirugose-punctate, 
the sutural and lateral margin partly, black. 
Length 4 lines. 
Head impunctate, the extreme vertex (more or less distinctly) 
black, the space between the eyes with a longitudinal groove; 
the jaws black at their apices; palpi slender, testaceous; an- 
tennae more than two thirds the length of the body, very slender, 
testaceous, the apical joints fuscous, the third double the length 
of the second, the following nearly equal; thorax twice as
