DESCEIPTION OP THE PLATES. 

 Plate X. 

 Fig. 1. Typical antennte of Entomobrya, X 50. 



2. Claw (side view), X 200. 



3. Claw (semi-dorsal view), x200, showing lateral plates. 



4. Tenent hair, seen from above. 



5. Left eye-patch, X 300. 



6. Clubbed hair from thorax, X 100. 



7. Spring, x50. 



8. Miicro, under view, 



_ ^, . T . I X 200. a, Seta3 on the sides of the denies. 



y. The same, side view> J 



10. The same, apex, X 800. 



11. Seta from miicro, X600. 



12. E. nivalis, L., Xl6. 



13. E. intermedia, n. sp., Xl6. 



14. The same, X 16. This specimen has been flattened a Little by the 



cover-glass pressing a httle on it, so that the body looks wider and 

 more fusiform than it really is. 



15. E. intermedia, Xl6. Young specimen. The central patch uniting 



the two lateral bands on the fourth abdominal segment only appears 

 of a little darker yellow colour in the specimen, but this in f)hotography 

 takes dark. It evidently shows that the band is in process of for- 

 mation. 



16. E. intermedia, var. elongata, X 16. 



17. E. albocincta, Temp., X 16. 



Plate XI. 



Fig. 18. Entomobrya inultifasciata, TuUb., y^kv. pulchclla, Eid., Xl6. 



19. E. multifasciata, Tullb. (dark form), X 16. 



20. The same (type), X 16. 



21. The same (pale form), X 16. 



22. The same, approaching var. Tslicoletii, Labk., X 16. No central dorsal 



markings. A line in front of the head, and another along the epi- 

 mera, besides the marks on the third and fourth abdominal segments. 



23. The same, var. iV2'cofe;;M nearly, Lubk., X 16. The upper part of the bands 



on the fourth abdominal segment (a) only appears in the object itself 

 as darker yellow than the surrounding colour, and thus, by photo- 

 graphy, come out as bands. This is very interesting, as showing the 

 transitional stage in which this specimen is. This is evidently a 

 young form. 



24. The same, var. Nicoletii, Lubk., xl6. 



25. The same, var. lanuginosa, Nic, Xl6. Although this specimen has 



no markings, the dark body-colour on the fifth and sixth abdominal 

 segments (a) and the base of the fourth comes out by photography as 

 darker bands, showing an approach to var. Nicoletii, Lubk. 



26. The same, var. lanuginosa, Nic, X 16. This is a typical specimen.
