the male differs greatly from that of Arraphytarsa or Allokotarsa ; 
the joints are cylindrical, fused without traces of suture, the place 
of the latter is, however, indicated by one or two inner and outer 
bristles, the last joint is slightly dilated at the tip, the inner claw is 
short, double, the inner tooth much thicker than the outer, the outer 
claw is much longer, not deeply cleft at the tip, and the inner lobe 
is wider than the outer; intermediate and posterior claws very deeply 
cleft, the two teeth strongly hooked, the upper one only half the 
thickness of the lower.

ALOGISTOTARSA STRAMINEA, N. Spec. 
Light straw-colour, with an iridescent sheen, head more or less. 
deeply infuseate ; clypeus constricted laterally close to the apex and 
with the anterior margin plainly tridentate, excavate in front of the 
supra-median transverse keel which runs parallel to the frontal 
suture, apical part of the clypeus smooth, posterior finely punctate, 
frontal part also closely punctate ; prothorax rounded laterally in the 
anterior part, but not towards the base the angles of which are 
distinct, somewhat convex, fringed laterally with equi-distant 
bristles, and covered with fine, shallow punctures; scutellum faintly 
punctate ; elytra sub-cylindrical, striate, with the punctures on the 
non-convex intervals slightly rugose, and not deep; abdomen and 
metasternum very strongly compressed laterally, iridescent ; 
pygidium convex, punctulate, each abdominal segment with a row 
of deep setigerous punctures. 
Length 54 mm.; width 24 mm.

ALOGITOTARSA OVAMPOANA, 0. Spec. 
The description of A. stramuinea applies entirely to this species, 
which, however, differs in being much more deeply punctured all over, 
in the absence of iridescence, and in being testaceous instead of 
straw-coloured; the frontal part of the head is redder than the 
prothorax, but is not infuscate, and the striation on the elytra is 
deeper than in A. straminea. 
Length 6 mm.; width 34+ mm.
