7660/374). The last number is the first of two specimens mentioned 
by Mayr as the ones on which he based his D. sculpturatus , but his 
figure and description are not drawn from this specimen. It is rather 
badly decomposed and thouoh it is in clear amber and in a favorable 
position to show the general form of the body, the sculpture is very 
indistinct. 
D. vexillarius seems to be most closely related to the recent 
D. monoceros described by Emery from New Guinea. This form, how- 
ever, is not strongly sculptured and the erect epinotum is prolonged 
in to a sinuous, horn-like projection above.

As stated in Connection with the preceding species, Mayr based 
his Hypoclinea sculpturata on two specimens, No. 374 in the Geolog. Inst. 
Koenigsberg. Coli, and a specimen in the Menge Coli. His description 
and figures are drawn from the latter alone, which is to be regarded 
as the type, whereas the former is a very different species, which 
has been described above as D. vexillarius. 
The worker of D . sculpturatus measures only 4 mm in length 
and is, therefore, decidedly smaller than the workers of the two 
preceding species. The head 
is proportionally shorter and 
broader and less narrowed 
behind, the eyes are large but 
less convex, the thorax is 
shorter and the base of the 
epinotum less elevated and 
when seen from above much 
less narrowed anteriorly, with 
straighter sides and posterior 
border and the declivity is 
more concave and perpen- 
dicular, lying completely under the base. There is no meso- 
sternal tooth. The petiole has a lower node, which is much less 
compressed anteroposteriorly and with a blunter border. There is a 
slight constriction between the first and second gastric segments. The
