Glyptapis mirabilis Ckll. 
L. p. = Labial palpus. Md. — Mandibles. 
M. p. = Maxillary palpus. Mx. = Maxilla. 
Tongue rather broad, short, with a broad button-like strncture 
at end ; surface of tongue transversely lined as usual. 
Blade of maxilla, of ordinary form, 
rather broad, with erect bristles on 
outer side and oblique ones on inner. 
Tongue and maxillae reaching about 
the same point, namely the end of the 
second joint of labial palpi. 
Maxillary palpi slender, with three 
movable joints, and no doubt a fourth 
basal one, wliich cannot be distinctly 
seen; last joint long and very 
slender. 
Labial palpi moderately elongat- 
ed; first joint apparently short, second 
long, third and fourth smaller, but in 
a straight line with the others, the 
third cordiform, the fourth slender. 
The second joint has very long hairs 
on the inner side. 
Mesothorax and scutellum with 
exceedingly large and strong punc- 
tures, closely placed but not confluent; 
metathorax divided by ridges into large 
subquadrangular areas; two continuous 
ridges run obliquely down eacli side, 
the inner ones to meet and thus out- 
line a very large triangulär basal area, 
the apical part of which is occupied 
by a very large fovea, the lateral mar- 
gins of which are finely transversely 
ribbed; anterior to the fovea, in the 
basal area proper, four median spaces, 
separated by ridges formin g a cross, 
are especially conspicuous. The post- 
scutellum is finely punctured, and has 
a very large fovea on each side. 
Legs with abundant coarse brown hair or bristles, the scopa of 
hind legs sparingly plumose; the three middle tarsal joints of anterior 
legs very broad and short, obliquely cordiform; pulvillus large; claws 
with a short inner tooth beyond the middle. 
Glyptapis mirabilis Ckll. 
Diagram showing sculpture of hind part 
of thorax. 
Sc. — Scutellum, with a row of minute 
foveae along hind margin. 
Ps. — Postscuteilum, finely punctured, 
and with a very large fovea on 
each side. 
Mx. = Metathorax.
