i apex extending to ncar middle of suture, i sides running indistincUy below
humeri; behind this an indistinct, oblique, whitish fascia which attains the suture
but which is displaced laterally by fulvous-gray pubescence, this pubescence covers
most of the sides and the Bpienl region, where it is mottled indistinctly with dark
brown. Body beneath dark reddish-brown, irregularly covered with fulvous-gray
pubc.:icence; abdominal sternites fuscous, apices of second to fourth sternites testa­
ceous, entirely fulvous-gray pubescent, mottled rather densely wit,h dark brown,
the fulvous-gray more or less condensed laterally to form two poorly-defined vittae
each side, one marginal, the other about half-way between margin and middle.
Legs dark reddish-brown to fuscous, irregularly fulvous and fulvous-gray Pllbesccnt;
met.'lfcmorn banded at middle with brown; tarsi reddish-brown, hoary pubescent,

just behind middle each side a feeble tubercle, which is less visible than the sulcus
placed anterior to it; apical transverse sulcus obsolete, basal one narrow but rather
distinctly impressed, especially at middle and at lateral termini, where they are
connected to the lateral oblique sulci; disk with median callosity obsolete, distinct
only before basal transverse sulcus, eacb side broadly nnd strongly tumid, entirely
