and the genital segment of the male is tuberculate; pro-

posterior lobe most commonly pale or variegated with 



pale. Posterior tibia furnished with long rigid subspini- 



form setse [bristles]. 



E. Antennae nude or with shorter pubescence, first segment 



sometimes furnished with a few shorter setae. Lateral 



[more narrowly] expanded margin of the pronotum not 



at all or rarely sparingly punctate; anterior disk of the 



pronotum most commonly smooth or sparingly punctate, 



rarely densely punctate Beosini StS,l. 



EE. Three basal segments of the antennae provided with 

 rigid setose bristles. Lateral [more widely] expanded 

 margin of the pronotum and corium commonly [pro- 

 fusely] punctate. Clavus irregularly punctate. Dorsal 

 parts commonly pale [and profusely punctate] 



Gonianotini Stal. 

 BB. The posterior glandular, opaque spot of the fourth ventral 

 segment of the abdomen placed closer to anterior spot, most 

 remote from the posterior margin of the segment, sometimes 

 furnished with a third, posteriorly placed, spot. [With 

 lateral margin of pronotum most commonly expanded, this 

 frequently foliaceous between the lobes.]. . .Lethceini Stal. 



Tribe Myodochini Stal. 



A. Head very much exserted, drawn out into a long cylindrical 

 neck at base ; longer than pronotum. Two lobes of pronotum

 cylindrical neck. Collar more rarely absent (see Div. CC).

 middle; anterior lobe in all macropterous forms and in most 

 brachypterous forms never or scarcely ever more than twice 

 as long as posterior lobe, if more than doubly longer then
