GENUS ENTOMOBRTA, EOND. 275 



are already present. Tliere is as yet no triangular patch con- 

 necting the two lateral bands on the fourth abdominal segment, 

 though the photograph shows indications of one. This is owing 

 no doubt to the actinic effect of the darker yellow of the skin 

 prior to the formation of distinct markings. The fourth abdo- 

 minal segment is longer than the three preceding and the meta- 

 thorax taken together. The upper claw appears untoothed ; the 

 lower one nearly as long as the upper in the third pair of legs, 

 not so long in the others. Tenent hair not much dilated. 



This species comes nearest to E. nivalis, both in shape and in 

 markings. In shape it differs in having the antennse longer and 

 not so dilated ; the fourth abdominal segment longer and not so 

 tapering, so that altogether the animal is less fusiform than in 

 E. nivalis. In markings the chief differences are the triangular 

 patch uniting the two lateral bands on the fourth abdominal 

 segment and the central basal spot on the same, both of which 

 seem very constant in this species, and which I have never ob- 

 served in any other Tlntomobrya. 



This species has been sent to me by Mr. J. Sinel, of Jersey, 

 who has gathered it several times from May to August 1882 on 

 the surface of stagnant pools. Hitherto-' I am not aware of its 

 being found in England. I have, however, amounted specimen 

 sent me by Miss Grarrod, and labelled " Kahlenberg Woods, near 

 Yienna, August 1882," which is probably a pale variety of this 

 species. The shape, particularly in the antennse, is that of E. in- 

 termedia ; but the markings are more like Lubbock's E. Nicoletii, 

 with these additions, that there is a faint lateral band running 

 the length of the thorax and first three abdominal segments, a 

 pale streak on each side of the fourth abdominal segment and a 

 central dark line at the base ; there is a prominent central black 

 band on the fifth abdominal segment. I have also had the oppor- 

 tunity of examining another specimen, which convinces me that 

 this is at any rate a distinct variety, and I have named it provi- 

 sionally var. elongata.
