7660/374). The last number is the first of two specimens mentioned 

 by Mayr as the ones on which he based his D. sculpt ur at us, 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. Coll. and a specimen in the Menge Coll. 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

 compressed anteroposteriorly and with a blunter border. There is a 

 slight constriction between the first and second gastric segments. The
