The fourth abdominal segment is 3 — 4 times as long as tlie 

 third. The first joint of the antennae is the shortest, the second 

 longer than the third, the terminal joint being the longest. A 

 basal ring is often conspicuously differentiated at the base of the 

 first joint. 



The anterior eyes are a little larger than the posterior, but 

 the two posterior ones of the inner row are not, as is usually 

 the case in other species of this genus, smaller than the rest. 

 Their position also differs from the typical one in the genus 

 Entomobri/a, for the last or hindmost ocellus in the inner row is 

 situated behind all the others instead of being situated in front 

 of the last or hindmost of the outer row. (Fig. 1.)

 Entomobrya Lönnbergi n. sp. 1 Eyes. 2 Foot. 2 Mucro. 



The tibia is provided with one tenent hair, swoUen at the 

 end and shorter than the upper claw. The upper claw is large, 

 provided with three very conspicuous teeth, distally decreasing 

 in length. (Fig. 2.) 



The structure of the falcated mucro, which only carries one 

 tooth (and one spine) would give the species a place in the genus 

 Drepanura, established by ScHÖTT, if that genus bad not been, 

 with good reason as it seems, both by its author and by others 

 referred to and included in Entomobrya. (Fig. 3.)
