the basal and the small atrophied apical 
articles deplanate triquetrous, com- 
1 posed of 8-10 joints ; vertex transverse, 
very broad, or strongly acuminate 
produced . : . Tripetalocerins 
(Antenne filiform . ; a 
(Anterior femcra above distinctly rateaie : 
pronotum anteriorly produced over the 
J head in a cornute process ; antenne 
\ with 16-22 joints. ; . Batrachidiane 
Anterior femora more or less compressed 
L carinate above . : : me) 
Frontal costa widely fortea) the rami 
forming a frontal scutellum Cladonotinee 
3< Frontal costa furcillate, but the rami 
diverge only moderately, or parallel, 
very frequently separated by a sulcus. 4 
Pronotum anteriorly truncate, or rarely 
angulate produced; posterior angles 
of the lateral lobes of pronotum turned 
down, more or less rounded ; first hind- 
tarsal joint longer than third — . . Acrydine 
Pronotum truncate anteriorly, posterior 
angles of lateral lobes laminate pro- 
duced outwards, acute, or posteriorly 
obliquely truncate, rarely turned down 5 
Posterior angles of lateral lobes of pro- 
notum produced outwards, often spined ; 
first joint of posterior tarsi longer than 
third ; posterior tibiee strongly ampli- 
ate, or margins dilated toward the 
apices ; very frequently not or sparingly 
spinose . . Scelimenine 
Posterior angles ai Tatoral ee ‘i pro-
