68. MYRMICA GLOBULARIA. 



Worker. Length 1 line. Pale rufo-testaceous, very smooth 

 and shining, with a rufo-fuscous band on the first segment of the 

 abdomen, the basal and apical margins pale. Head rather 

 wider than the thorax or abdomen, the thorax strangulated in

 node large and globular, much larger than is usual in the genus.

 the thorax oblong-ovate; the wings hyaline and beautifully iri- 

 descent ; the nodes of the petiole of the same relative proportion: 

 as in the workers ; abdomen oblong-ovate, rufo-fuscous, with the

70. MYRMICA BLANDA. B.M. 



Worker. Length 1 line. Head and thorax ferruginous ; ab- 

 domen black or brownish-black, with the apex rufo-testaceous. 

 The head, thorax, and nodes of the abdomen finely rugose : the 

 roughness is occasioned by the excessive closeness of the punc- 

 tures ; the club of the antennse 3-jointed ; the legs rather paler 

 than the thorax; the thorax convex and rounded in front, 

 narrowed posteriorly, with two acute spines on the metathorax. 

 The abdomen very smooth and shining.
