stinguishing them at first sight ; and upon further comparison, 

 the absence of the transverse line of impressed dots upon the 

 last joint of the abdomen, as well as the great difference in 

 the mandibles, independently of the variation in the wings, 

 excite our astonishment that Jurine should have rejected a 

 Genus so natural and well established. 



Dr. Leach has divided this Genus into those with the apex 

 of the abdomen entire, 1. H. punctatum Leach?; 2. lucidulum 

 Geoff.; 3. ardens Lat. The others notched at the apex, 

 4. resium Geoff. ; 5. molaceum Rossi. There are also in the 

 Museum cabinet a species called ccendeum and another un- 

 named. Our insect, which was taken several years back in 

 Norfolk, agrees tolerably well with Latreille's description, and 

 perfectly with the British specimens in the Museum, but not 

 very well with the rude and careless figure in Coquebert. 

 Some specimens are twice the size indicated in the plate by 

 the crossed lines. 



The habits of this Genus are somewhat dissimilar to those 

 of the Chrysidce, being generally found in the sunshme upon 

 the leaves of brambles and other bushes, from which they fall 

 upon being approached, rolling themselves up into a ball. 



The plant figured is AjitirrJmium Ci/mbalaria (Ivy-leaved 

 Snapdragon).
