CainponotiiHc.—The amber species of CEcopliyl/a, Gesomyrmex,Dimorphomyrmex and Rhopalomyrmex are worthy of note. CEco-phylhi and occur both in the Baltic and Sicilian ambers,CE. brischkei and G. ha-rncsi (Fig. 100) in the former and CE. sicitlaand G. cornigcr (Fig. 101) in the latter. These species of (Ecophyllnare closely related to CE. smaragdina, the well known red tree ant of the. FOSSIL AXTS. *73 Old \Yorld tropics. was supposed to be an extinct genustill Ern. Andre (1892^) described a species (G. cliapcri) from tbe same paper and from the same locality he described the type ofanother interesting- Camponotine genus, Dimorphomyrmex jancti Thislias polymorphic workers with large reniform eyes and 8-jointed an-tennae. Some years later (19051*) Emery found a species (D. 98) of this same genus in the Baltic amber. Rhopalomyrmex(Fig. 91) resembles the neotropical Myrmelachista. It has lo-jointedantennas, with 4-jointed clubs. Only a few species of the recent generaLasins, Formica and Camponotns have been described from the Balticamber. The workers of oneof the Camponoti, C. con-strictits (Fig. 102), are pecu-liar in possessing ocelli andin having a thorax like For-mica. Of this latter genusMayr described only a single species, F. flori, which is FIG. 102. Worker of Components const
