The greatest confusion formerly existed in the synonymy of this 

 species, as its male was incorrectly treated as that of Formicoxenus 

 nitidulus, and it was not until Er. Andre 42 first pointed out the 

 error, in 1881, that the matter was finally cleared up. 



Stenamma westwoodi is a rare species of obscure habits ; accord- 

 ing to Andre 42 it occurs in shady places in woods and forests, 

 nesting in the earth under moss and dead leaves, the nest being 

 difficult to detect, and Mayr 27 states its habits are similar to those 

 of Leptothorax. Nylander 15 records it in moss in the Forest of 

 Fontainebleau, von Hagens 35 in all the woods at Cleve, single 

 workers being found in moss and under leaves, and Wasmann 48 

 took it occasionally under leaves in Dutch Limburg. 



For el 36 mentions that Emery discovered it at Prilly near Lausanne, 

 and that they both took a number of workers at roots under dry 

 leaves on the borders of a stream in a wood there in September, 

 1873, but no nest was found. I also captured a number of workers, 

 in moss, in company with Myrmica ruginodis, on April 30th, 1905, 

 at Ditchling in Sussex, but could not trace their nest. 



Tuck records a specimen in a nest of Bombus terrestris 57 found at 

 Tostock 60 , and Farren-White the capture of a worker with a dead 

 companion in its mandibles in the Valley of Rocks at Lynton 55 . 



Von Hagens 34 once found an independent colony at Elberfeld, 

 consisting of a deflated female and workers, and Wasmann another, 

 situated under a stone in a wood at Laacher See (Rheinischen 

 Vordereifel) in August 1889, some eighty workers and twelve 

 males being present, no female however being found 48 49 . 



This Stenamma has been frequently taken with other ants ; von 

 Hagens speaks of it as presumably a guest-ant, the workers 

 occurring preferably in, or near, other ants' colonies 33 , and Escherich 

 as commonly in the neighbourhood of other ants' nests 65 . 



Andre considers its occurrence in such situations as only acci- 

 dental 42 , and Wasmann is of the opinion that it is not a myrmeco- 

 philous species 54 ; nevertheless the records with other ants appear 

 to me to be too numerous to be treated as of purely accidental 

 occurrence. F. Smith records its capture amongst a colony of 

 Formica fusca, by Reading in July, 1857, near Plymouth 18 twice in
