Rev. " Hemiptarsenus fulvicollis W. is an exceedingly com- 

 mon little insect, and has two remarkable characters ; first, 

 the variation of the colour of the thorax, two being seldom 

 found alike (bright green is, perhaps, the prevailing colour, 

 which, by the by, makes fulvicollis a bad name) ; and, se- 

 condly, the beautiful snow-white tips to its antennae. Nei- 

 ther of these characters are noticed." 



Ans. I have never seen but two specimens in which the 

 colour of the thorax offered no variation. It was not neces-

 notice every character, but rather such as would enable any 

 person to recognise the insects described. Those which I 

 selected were evidently sufficient, since they enabled the 

 reviewer to do this. — J. O. Westwood. The Grove, Hammer-
