SCIENCE. 



BY G. II. TEEBALL, F.E.S. 



Among many other novelties to Britain, Col. Yerbury has taken 

 this year at Nethy Bridj^e in Inverness-shire, four females of this

Callicera yebburtt, n. up.

 brevior. Thorax hand striatus. Abdomen apice nigro-hirtum, viltis in segmentis 

 \mo et 2do Iransversis nigris obscuris. Femora infemina totafulva. 



The nearest ally must be the little known C.porrii, Rond., which, 

 however, has a conspicuously striped thorax and black femora. I will 

 shortly give a paper describing it more fully, and dealing with all the 

 known species of the genus.
