second of the large foveas lie over the third stria, the third 
and fourth over the second. 
B. tripunctata, n. sp. 
Fulvo-testacea, capite postice, thorace et elytris fusco- 
plceis ; thorace quactrato, angulis ct lateribus anticis ro- 
tundatis, angulis posticis obtusis ; elytris obtuse trun- 
catis, fortiter punctulato-striatis, interstitio 3'° tripunctato. 
Long. 8:^—4 lin. 
Tanga, Kawachi ; on foliage. 
Eyes exti-emely prominent. The whole head and an- 
tenna} are sometimes tawny-yellow, except a dark patch 
on the crown. The thorax is nearly as long as broad ; 
rounded as usual anteriorly, moderately sinuate-angustate 
posteriorly, with the hind angles, though prominent, 
rendered obtuse by the obliquity of the sides of the base. 
The elytra are dilated posteriorly, but obtusely truncate, 
the outer angles being rounded, and the truncature not at 
all sinuate ; the surface is deeply striated, and the stria? 
jmncturcd ; the interstices sparsely piuictulate ; the margins 
are more or less rufous. 
Taicona, nov. gen. 
Gen. Bothy nojdera proxime affinis ; differt mento dente 
valido armato. Caput, cum oculis valde prominentibus, 
thorace latins. Labrum antice dilatatum, medio leviter 
sinuatum, angulis rotundatis. Pal]ii truncati,liaud securi- 
formes. ]\Ientum medio dente valido armato ; lobis acute 
triangularibus, epilobiis acutissimis, longioribus. Ligula 
quadrisetosa, setis externis longioribus, paraglossis intus 
infra apicem conniventibus. Elytra fortiter striata, me- 
tallica. Tarsi supra pilosi. 
By its hairy tarsi this genus belongs to the section of 
CaUeidince in Baron Chaudoir's classification to Avhich 
Bothyvopiera belongs ; but the form and armature of the 
mentum is quite different ; in fact the change of form of 
this organ in genera so closely allied quite destroys one's 
confidence in its importance as a systematic character. It 
is furnished with a large triangular tooth ; and the lobes, 
instead of being broadly rounded at the sides and tip, as 
in Bothyvopiera, Crossoylossa, Sec, taper in a straight 
line to a pointed apex, surpassed by the spiniform epilobes. 
The tarsi have the narrow form of those of Calleida, with 
the basal joint, in the posterior feet, nearly as long as the
