No. 22.] HYMENOPTERA OF CONNECTICUT. 599 



Suffield (Dimmock) ; Branford, Cheshire, Mt. Carmel, New 

 Haven (H. L. V.) ; New Haven, Salisbury ( W. E. B.) ; Crom- 

 well, Hartford (Forel) ; Winsted, Norfolk, Colebrook (W. 

 M. W.). 



F. fusca var. subaenescens Emery. 



A rare species, apparently, in New York and New England, 

 but common in the Northern Middle States (Illinois, Wiscon- 

 sin, Michigan). It differs from the preceding variety in having 

 a more metallic and less pubescent surface. It prefers to nest 

 under logs and stones in rather shady woods. 



Connecticut (Emery) ; Colebrook ( W. M. W.). 

 F. subpolita Mayr. 



I have not seen specimens of the typical form of this species 

 from the State. It is possible that Mayr's specimens may have 

 belonged to the following species. 



Connecticut (Mayr). 



F. neogagates Emery. 



Nesting in rather small colonies under stones only on the hills 

 at an altitude of about 1,000 feet or more, according to my obser- 

 vations. The males and winged females appear during late July 

 and early August. 



Kent, Salisbury ( W. E. B.) ; Norfolk, Colebrook (W. M. W.). 



Polyergus Latreille. 



P. lucidus Mayr. 



This rare and beautiful species, the " shining slave-maker " 

 of McCook, or " shining amazon," as it may be called, uses the 

 workers of Formica schaufussi as slaves, or auxiliaries. These 

 are bred from pupa? kidnapped from their maternal nests by the 

 warlike lucidus workers. The latter are quite unable to feed 

 themselves, excavate their nests, or care for their own brood, but 

 have to depend for these important activities on the schaufussi 

 workers. Hence the ants of this species are quite unable to live 

 an independent life and may be regarded as permanently para- 

 sitic on fragments of schaufussi colonies which they bring to- 

 gether with great skill. The sexual forms make their appear- 

 ance during August. 



Connecticut (Mayr).
