Few orders present a greater variety of outline or more beautiful 

 sculpture than the European Hemiptera, and even the Coleoptera 

 and Lepidoptera cannot exceed many of the Indian and South 

 American species in the brilliancy and powerful opposition of their 

 colours. With such attractions, therefore, it is not a little surpri- 

 sing that in this country they should have been totally disregarded, 

 and whilst on the one hand we have been assisted by IVIarsham's 

 Coleoptera, and on the other by Haworth's Lepidoptera, we have 

 no guide to the Hemiptera, except in the rare and incomplete works 

 of our continental neighbours. Such were my remarks in May, 

 1824', and as the same are still applicable, I can only refer to M. 

 DeLaporte's Monograph, an excellent memoir by Dr. Burmeister 

 in the Revue Entomologique, and to Hahn, who has divided Pen- 

 tatoma into the following genera, distinguished apparently by the
