were able to find even the curious transitional form between the worker 

 and the true female, noted in this Magazine, vol. xxv, p. 61. 



I have to thank Prof. Emery, of Bologna, to whom I have sub- 

 mitted all my difficulties, as well as Monsieur E. Andre and Professors 

 Mayr and Eorel, for most kindly helping me when I applied to them. 



Family FOEMICID^. 



Camponotus, Mayr. 



micans, Nul. — $ major and minor, Tangier, under stones. 



cruentatiis, Latr. — $ major and minor, Gibraltar and Tangier, and one ? , 

 Tangier, under stones, in large communities. 



rubripes, Drury : race cognatux, Sm. — (?,?,$, major and minor, Gibraltar, and 

 two (JjTetuan, one ^ , Tangier. The females of this race may be known from 

 stflvaticus by their dull surface, and by the distinct channelling of the posterior 

 tibiae, also by the distinctly longer joints of the flagcllum and the slightly longer 

 metathorax ; the males are larger than those I have of aylvaticus, with paler an- 

 tennae and longer joints to the flagellum and paler tibiae and tarsi ; the thorax also 

 is distinctly longer, and the metathorax less suddenly declivous posteriorly. The 

 genital armature, however, shows no characteristics of importance, the only apparent 

 one being the greater divergence of the apices of the sagittae. 



Eace Alii, Forel. — ^ , major and minor, Tetuan and Esmir, Marocco. 



Kace sylvaticus. — <?,?,$, received only from Tangier. 



Sicheli, Mayr. — $ , a fair series, major and minor, from Gibraltar. $ , a few 

 females received with the above workers appear to differ from lateralis in liaving 

 the metathorax slightly narrower posteriorly and not so abruptly declivous ; in 

 colour they are black, with only the tibiae, tai'si and autennae pitchy. I sent one to 

 Professor Emery, who pointed out the metathoracic character which had escaped my 

 notice. ^ , with the other sexes I have received three males, one of which I have 

 dissected, and the genital armature certainly differs distinctly from that of lateralis 

 in being proportionately smaller, with the apical part of the stipites (corresponding 

 to the lacinia in the Anthophila) slightly longer and narrower in proportion, and 

 angulated longitudinally, and with the volsella distinctly shorter, narrower and more 

 curved, not nearly reaching to the apex of the sagittae. Prof. Forel remarks that 

 the metathorax is slightly shorter than in lateralis. 



CoiOBOPSis, Mayr. 



truncata, Spin. — $ , one specimen only, from Tangier. 



MYEMECOCYSTtrs, Wcsm. 



viaticus, Fab. — $ , four, Tangier, of rather small size. 



pallida, Mayr. — $ , one specimen, from Gibi'altar, agreeing well with Mayr's 

 description (Reis. Turk., ii, p. 9), and with the apical ventral valve shaped as in 

 Andre's figure (Form. d'Eur., pi. ix, fig. 16). The laterally compressed genital 

 armature is very characteristic, and distinct from that of viaticus. The stipites, 

 looked at from above, are narrow and long, only slightly divergent and truncate at 

 the apex, near which they are impressed with several very large punctures, and from 

 the lower margin near the apex extends a lateral triangular process, nearly mem-
