ScELio Is another of Latreille's genera which has not been 

 recorded in any British work excepting the " Guide to an 

 Arrangement of British Insects ;" with the continuation of 

 which I shall now proceed, I hope, without further delay. 



Scelio bears a considerable resemblance to Sparasion 

 (plate 317), but is distinguished from it by the 10-jointed an- 

 tennas of the male, as well as by the form of the maxillae and 

 their palpi. I have been able to detect by dissection twelve 

 joints in the antennae of the female (fig. 1. a.) ; and having at 

 the same time extracted the ovipositor, no doubt can remain 

 of its being that sex : this, as well as the third joint of the 

 labial palpi, were apparently unknown to Latreille. 



There is but one species belonging to the genus Scelio : I 

 first took a male near Niton, in the Isle of Wight, the middle 

 of September 1826 ; and Mr. Francis Walker has since found 

 a female upon a window at Southgate, in the month of July. 



Scelio rugosidusy as well as Spat-asionfrontale (lately figured), 

 is found in the neighbourhood of Paris, generally upon the 

 ground in fields. I took a specimen of the latter insect upon 

 a wall near Marseille, the end of last June. 



The plant is Cheirantlius fruticulosm (Wall-flower), from 

 Dover Chffs.
