The eggs are spindle-shaped, 0'47 mm. long and 0'2 mm. in di- 

 ameter, of a pure milk-white, and are laid somewhat irregularly, but 

 with a tendency to be packed closely side by side. Mr. Fowler 

 appears to entertain the idea that the egg is laid in the wasp cell ; 

 this may justify my stating two reasons why this would be extremely 

 improbable, even if I had not otherwise rendered it practically certain 

 that the actual habit is very different. First, a personal reason ; I 

 have met with hundreds of Rhiphiphorus in all stages, only once as a 

 free larva, but abundantly within the wasp larva, and at all stages 

 forward to the perfect beetle, but have never seen any indication of 

 an egg within the cell. Secondly, the wasp develops with extreme 

 rapidity, yet the Rhipipliorus keeps up with it, or, indeed, overtakes 

 it ; there would thus be really no time for the development of the 

 young larva within the egg, even were it as rapid as is at times the 

 case in Chri/sis. The nature of the ovipositor, egg, and young larva, 

 nevertheless, plainly indicates that the larva must take some time to 

 mature in the egg, and that the species is not viviparous.

NOTE ON A NEW CICINDELA FROM NORTH JAPAN. 

 BY G. LEWIS, r.L.S. 



CiCINDELA AINO, n. SJ). 



C. niohozana simillima, supra cupreo-fusca. JElytris, pnncto humerali et 

 post humerali, fascia flexuosa media, lunula apicali alhis ; lahro alio 

 travsverso. 5 . Length, 16 mm. 



This species is the size of and very similar to C. niohozana. Bates, but it is 

 darker in colour and has the labrum much shorter and more transverse. The elytral 

 markings are similar in both species at the humeral angle and in the spot below the 

 shoulder, but the median fascia in C. aino is less angulate in the centre, and the 

 apical marking is not a circular disc, but a crescent embracing the tip of the wing- 

 case like that seen in C. Lewisi, Bates. The thorax is somewhat quadrate, as in 

 C. niohozana. Cicindela sachalinensis and Raddei also belong to this group. 



I am much indebted to Mr. Bates for the intimation, after a 

 careful examination of the specimens, that the species has not until 

 now been described. 



Hab. : Tezo and Saghalin. I have two female examples from 

 the Ishikari Eiver in Yezo, and Mr. Bates has one from Saghalin.
