interesting 1 forms, many of which Mayr originally assembled in the 

 genus Hypoclinea. Among these it is now possible to recognize species 

 of Dolicliodcnis, Iniioniynnc.v and Bothriomyrmex. I have already 

 called attention to the great abundance of two of the species of Bothrio- 

 in \niic.v and Iridomyrmex. In the material sent me by Professors 

 Klebs and Tornquist there are single specimens of two new genera 

 (Prolancnrctus and Parancnretns) of unusual interest. Both of 

 these are closely allied to Anenrctns, a genus which is now repre- 

 sented by a single species, A. siuwni, described by Emery from 

 Ceylon (Fig. 140). This ant combines both Dolichoderine and

Ponerine characters, having the head of the former, and the petiole 

 and sting of the latter subfamily. In the Sicilian amber Emery has 

 recognized a male Leptomyrmex (L. maravignce), a genus now con- 

 fined to Australia and New Guinea, an extremely small Tapinoma (T. 

 minutissimum) and a Technomyrmex (T. dcletus). As the Doli- 

 choderinse are practically absent from the African continent, the 

 great development of this subfamily in the two ambers shows that the 

 complexion of the European Tertiary ant-fauna was decidedly Indo- 

 australian. 



4. CainponotiiHc. The amber species of CEcopliyl/a, Gesomyrmex, 

 Dimorphomyrmex and Rhopalomyrmex are worthy of note. CEco- 

 phylhi and Ccsoinynne.r occur both in the Baltic and Sicilian ambers, 

 CE. brischkei and G. ha-rncsi (Fig. 100) in the former and CE. sicitla 

 and G. cornigcr (Fig. 101) in the latter. These species of (Ecophylln 

 are closely related to CE. smaragdina, the well known red tree ant of the
