MR. J. S. BALY ON SOME GENERA 
Var. A. Elytris pallide flavis, utrisque limbo fasciaque prope medium 
nigro-piceis, pedibus fulvis. 
Var. B. Elytris fere totis flavis. 
Sab. Malay Archipelago, Batchian, Aru and Sulu Islands 
{Wallace). 
Vertex impunctate, impressed with a large round fovea; antennae 
three fourths the length of the body, second joint short, the third 
slightly longer, four or five lower joints flavous or fulvous, the 
rest nigro-piceous. Thorax nearly twice as broad as long ; sides 
rounded, the anterior and posterior angles produced, subacute ; 
disk transversely convex, smooth, impunctate. Elytra oblong- 
ovate, very slightly dilated posteriorly, convex, not depressed 
below the basilar space, remotely impressed with fine punctures, 
their interspaces very minutely punctured. Abdominal segments 
in some specimens narrowly edged with flavous. 
The outer margins of the flavous spots on the elytra are ill- 
defined, being more or less stained with piceous. 
G-enus Paraulaca. 
Corpus oblongum, convexum, postice paullo ampliatum. Caput exser- 
tum ; antennis filiformibus. Thorax transversus, dorso transversim 
sulcatus. Elytra convexa, confuse vel subseriato-punctata; epi- 
pleuris fere ad apicem extensis. Pedes simplices ; tibiis apice spiua 
brevi armatis ; unguiculis appendiculatis. Prosternum inter coxas 
elevatum, basi non lobatum ; acetabulis anticis apertis. 
Type Paraulaca ( Aulacophora ) angulicollis, Motsch. 
The above genus differs solely from Pseudocophora in having 
appendiculate instead of bifid claws ; occupying the same rela- 
tive position to that genus that Diacantha does to Aulacophora. 
In both genera the prosternum is not lobed at its base, and the 
apices of the epimera are free, not closing the acetabula. 
Genus Pseudocophora, Jacobi /, Notes Leyd. Mus. vi. pA69. 
The males of the present genus (so far as they are yet known) 
have a deep sutural fovea placed immediately below the basilar 
space on the elytra ; this fovea, the edges of which are thickened, 
is armed with two or four raised tubercles or teeth ; the number 
and shape of these teeth, taken in conjunction with the form and
