or five terminal joints rather shorter and often slightly thickened; eyes 
prominent, entire ; mentwm emarginate; terminal joint of palpi ovate ; 
epistome transverse, quadr- or pent-angulate. Thorax transversely con- 
vex, lateral border either obsolete or replaced by a single row of teeth. 
Scutellum semi-ovate. lytra oblong, closely punctured. Legs mode- 
rate in length; thighs moderately thickened, armed with a tooth be- 
neath; four hinder tiie, or often only the intermediate pair, notched 
at their apex; claws bifid. Prosternum oblong or oblong-quadrate, its 
anterior margin continuous with that of the episternum. Mesosternum 
oblong-quadrate. 
Type, Demotina Bowringii, Baly. China; Hongkong. 
The insects placed by me in the present genus divide themselves 
in two groups, viz. one in which the antenne are slender and fili- 
form, and a second where the same organs are somewhat shorter and 
more robust, being at the same time slightly thickened towards their 
extremity. The notched tibie separate the genus from Leprotes; the 
form of the scales, together with the wedge-shaped epistome, from 
Apolepis. The species have a wide range, from Japan to the Malay 
Archipelago, by far the greatest number being inhabitants of the 
latter, some of them being found in the Celebes and other islands to 
the east of Borneo. 
Demotina scutellata, Baly. 
D. oblong, subcylindrical; disk of thorax depressed, dark fuscous, sub- 
nitidous, covered with pale fulvous, narrowly ovate, adpressed scales ; 
scutellum, sides of thorax beneath, and epipleurz closely covered with 
white scales; antennz slender, filiform, their apex piceous.—Long 
22 lin. 
Hab. Northern China. 
Head triangular, rugose-punctate, covered with adpressed scales ; 
labrum fulvous; eyes large, black. Thorax one-half broader at the 
base than long, flattened on the disk, rugose-punctate, covered on the 
head with adpressed scales, lateral border obsolete, sides rounded 
posteriorly, narrowed from their middle to the apex. Elytra deeply 
punctate-striate, covered with adpressed scales; scattered here and 
there over the disk of each elytron are five or six small patches of 
white scales. 
Demotina Bowringii, Baly. 
D. oblong, subcylindrical, fusco-fulvous, subnitidous, covered with ad- 
pressed pale fulvous scales; elytra deeply punctate-striate, each elytron 
with four or five small black spots, three or four of which form an 
oblique fascia on the disk; thorax (its front.edge excepted) and breast 
piceous ; eyes black ; antennz subfiliform.—Long 12 lin.
