[March 
Mesepisternal-mesepimeral suture present; mesosternal-pleural su- 
ture present posteriorly, but disappearing anteriorly, apparently 
with fusion of the two sclerites (except in tenuicorne, where it may 
be complete). Metasternum with short anterior process meeting 
mesosternal process between mesocoxae, short process with bifid 
apex between metacoxae, and antecoxal sutures as in fig. 59 
( temporale only) or 60. Metacoxae excavate, i.e. with posterior face 
vertical and entire postero-ventral margin explanate (fig. 38). 
Legs rather slender; tibiae only slightly, if at all, wider at apex 
than at base, usually with some small spines on the external surface 
(slightly fewer to slightly more than in fig. 23), meso- and metatibia 
generally with more spines than protibia, the sexes usually similar 
within each species. Hind coxa and femur subequal in length, hind 
tibia about 0.9 times as long as femur, hind tarsus 0.5-0. 7 times as 
long as tibia. All tarsi with five segments, hind tarsus with last 
segment one-third to two-thirds as long as first four together. 
Bisetose empodium between bases of tarsal claws (see fig. 39). 
Elytra together about three-quarters as wide as long, each with 
eleven punctate striae (most clearly delimited in the middle section, 
more confused anteriorly and posteriorly) which are impressed 
between the punctures except in tenuicorne; eleventh stria (adjacent 
to epipleural keel) somewhat irregular. Macrosetae present on 
alternate intervals, associated in some species with raised pustules 
and/or spots; (except perhaps in tenuicorne?) intervals finely punc- 
tate between macrosetae (see figs. 26, 27, 29). Elytron with epi- 
pleural keel complete, serrulate in humeral region, intersecting with 
upturned lateral edge of elytron at about two-thirds the distance 
from elytral base to apex. Elytron covering abdomen through 
segment 5 or 6, with apparent elytral-abdominal interlocking patches 
on the internal elytral surface just antero-mesal to the confluence of 
the epipleural keel and elytral edge (see figs. 30, 31) and on the 
lateral area of abdominal segment 3 (see fig. 46). (Whole complex 
seen in detail only in pustuliferum and rotundulum; elytral patch 
present in all species except possibly tenuicorne; because of the 
limited number of specimens available of three of the species, an 
exhaustive search for the abdominal patches could not be made.) 
Elytron with patch of small single or grouped teeth near apex of 
ventral surface (as in figs. 30, 32, 33). Wings covering abdomen 
through tergite 3 when folded, except in brachypterous individuals
