[March 
Antennal length: from constriction between scape and its basal 
articulatory process to apex of last antennal segment. 
Ocellar diameter: measured antero-posteriorly in dorsal view. 
Pronotal width: maximum width. 
Pronotal length: along midline from base to apex, viewed per- 
pendicular to line of measurement. 
Elytral width: same as Width, above. 
Elytral length: measured along suture from apex of scutellum to a 
line tangent to elytral apices. 
Prosternal process length: measured along midline from a trans- 
verse tangent to the anterior margin of the procoxal cavities to apex 
of prosternal process. 
Procoxal length: measured in ventral view between transverse 
tangents to anterior and posterior faces of procoxae. 
Mesosternal length: along midline from anterior margin to apex 
of mesosternal process. 
Mesosternal process length: along midline from transverse tan- 
gent to anterior margin of mesocoxal cavities to apex of mesosternal 
process. 
Mesocoxal length: measured in ventral view between transverse 
tangents to anterior and posterior margins of mesocoxal cavities. 
Mesosternal procoxal cavity length: along midline from anterior 
margin of mesosternum to a line connecting the posterior edges of 
the cavities. 
Metasternal length: along midline between extremities of inter- 
coxal processes. 
Metasternal antecoxal sutures: measured from lateral limit to 
lateral limit. 
Metasternal width: between posterolateral corners of metaster- 
num. 
Hind coxal length: lateral edge to posteromesal corner. 
Hind femoral length: including trochanter, from posteromesal 
corner of coxa to most distal point of femur. 
Hind tibial length: along mesal side (not including any spines or 
setae). 
Hind tarsal length: from point of insertion of tarsus on tibia to 
tarsal apex, not including claws or empodial setae. The dividing line 
between the fourth and fifth hind tarsal segments was taken to be 
the point of insertion of the fifth segment on the fourth.
