Tapinoma Forster. 



50. T. sessile Say. — Camden Co. (Fox) ; Caldwell (Cresson) ; 

 Clementon (Viereck) ; Cape May (Phila. Acad.) ; Fort Lee, Halifax, 

 Lakehurst (Wheeler). 



Probably very common throughout the State. It nests under 

 stones, dead leaves, logs, bark, etc., usually in sunny places. The 

 larvae and pupae are salmon colored. The workers emit a peculiar 

 rancid-butter odor, the characteristic "Tapinoma odor," also ob- 

 served in the two following species. 



5 1 . T. pruinosum Roger. — Atco (Viereck) ; Halifax (Wheeler) ; 

 Lakehurst (Wheeler). 



The occurrence of this species as far north as New Jersey has been 

 overlooked hitherto. It is readily distinguished from T. sessile by 

 its smaller size, paler color, and silvery or frosty appearance. At 

 Lakehurst, it nests in pure, white sand, forming single or clustered 

 craters somewhat like those of Monomorium minutum. I have also 

 seen a colony nesting under a stone at Halifax and another near 

 Ramapo in the Ramapo Mountains. 



Dorymyrmex Mayr. 



52. D. pyramicus Roger. — South Jersey (Smith's List); Lake- 

 hurst (Wheeler). 



A few colonies belonging to a dark variety of this southern species, 

 near var. niger Pergande, were seen nesting in the white sand at 

 Lakehurst. It is probable that the species is really common in the 

 southern portion of the State as claimed in Smith's List. The nest 

 is a small regular crater 3 or 4 inches in diameter. 



Subfamily Camponotin^. 



Brachymyrmex Mayr. 



53. B. heeri depilis Emery. — Great Notch (Wheeler); Fort Lee 

 (Wheeler). 



This tiny ant is found nesting under stones in shady woods. The 

 workers seem to be subterranean in their habits, rarely or never com- 

 ing to the surface, at least during the daytime. They resemble the 

 yellow species of Lasius in their habit of cultivating root-cocci ds in 

 their subterranean galleries and chambers. The pupae are not nude, 

 like those of the following genus, but enclosed in cocoons. The males 

 and relatively large females make their appearance in late August.
