This widely distributed species is described by Nicolet as 

 "Smaller and more compressed than the preceding (Aphorura 

 fimetaria). Body irregularly dotted, quite brilliant metallic black, 

 paler beneath, with a few short hairs ; Posterior borders of the 

 segments slightly raised ; two transverse depressions at the an- 

 teritir border of each segment near the midline of the 

 back. Antennae paler than the body ; a slight depression 

 on top of the head between the eyes, which are black and 

 only 16 in number, placed in each lunule-like eyespot; the eye- 

 spots situated behind the antennae. Legs pale yellow (fauve). 

 Ventral tube large and deep ; no anal horns at the tip of the ab- 

 domen. Length, 1.5mm. First found under the bark of Larix 

 europea DG." 



Later writers speak of it as "without anal spines, post-an- 

 tennal organ, lower claw and furcula," though these are generic 

 rather than specific characters. The body is broadest at the 

 posterior part of the abdomen, which is broadly rounded off at 

 the end. The color of my specimens is dark blue, which is the 

 color given by most authors. The legs are pale blue, the claw 

 short, stout and unarmed, and at the tip of the tibia are borne 

 two long hairs which seem to me slightly clavate. Tullberg 

 figures but one such hair, and labels it "pilis apice arcuatus." 

 The antennae are longer than the head; Ant. I being about two-
