28 MYRMICA LIPPULA. 



Southend, at Shoeburyness, also at Deal and Dover, and will 

 probably be found along the whole line of the eastern and 

 southern coasts.

Female. Length 2-2^ lines. Pale ferruginous ; the head and 

 thorax reticulated, the reticulation inclining to striation on the 

 head ; the eyes small and black ; the metathorax transversely 

 striated at the base, the spines short and acute ; the wings hya- 

 line, the nervures and stigma pale testaceous ; the first node of 

 the petiole elongate, or petiolated, the second smooth and glo- 

 bose ; the abdomen oblong-ovate. 



Worker. Length 1-j- line. Rufo-fuscous, sometimes nigro- 

 fuscous ; the head anteriorly, the mandibles, antennae, legs, and 

 abdomen beneath, pale rufo-testaceous, sculptured like the 

 female ; the spines on the metathorax small and acute ; the 

 first node petiolated, as in the other sex; abdomen ovate, 

 smooth, shining and pale at the base and apex ; the eyes very 

 small. 



I have not seen the male of this species. Latreille describes 

 it as being "dark fuscous, or black, shining and pubescent; the 

 flagellum ferruginous, the scape fuscous ; the metathorax with 

 two little acute tubercles ; the tarsi pale, the wings very dark." 



I think it quite possible that the worker described by Latreille 

 is a variety of M. acervorum in this I agree with Dr. Nylander ; 

 and I am satisfied that the female is that of the present species ; 

 but as two, if not three, distinct species are described under the
