64 Rev. T. A. Marshall's monograph of 



Regarding the colours of this insect as fallacious, I 

 have tried to connect it by structure only with some of 

 the dark species. The perfect smoothness of the meso- 

 thorax separates it from all those above described 

 except apicalis, and from this it is easily distinguished 

 at a glance, as in the table of species. It is much too 

 large to be compared with either of the following species, 

 fulvipes or parvulus. On the whole it most resembles 

 similis, Cur., a common species, and said to have a pale 

 variety ; but the structure of the mesothorax does not 

 agree. It would not be surprising if the character 

 derived from the development or suppression of the 

 mesothoracic sutures should be found hereafter to be 

 valueless, although Fdrster founds a genus upon it, but 

 at present there is no ground for such an assumption. 

 There remains the pale variety of Wesmael's Microctonus 

 claviventris, already referred to under sp. 8. The meso- 

 thorax of this species is not characterised by Wesmael, 

 and, in order to arrive at some conclusion I applied to 

 M. de Borre, of the Musee Royal at Brussels, who took 

 great pains, with the assistance of Dr. Jacobs, to examine 

 Wesmael's types of this and allied species. The con- 

 clusions at which they arrived are that Enphorus ornatus 

 is not identical with any species in Wesmael's collection, 

 and further, that the insects standing under the name 

 claviventris as types, two in number, do not represent 

 that species, and do not correspond with the text of the 

 " Braconides de Belgique," while the so-called varieties 

 are a mixture of other species. 



The single example of E. ornatus was taken in a wood 

 close to my house at Nunton, Wilts.

Leiophron fulvipes, Cur., B. E., 476, 5 ; Hal., Ent. 

 Mag., ii., 46G, $ ? . 



Antennae ? 16-jointed, stout, not longer than the head and 

 thorax. Piceous, antennae at the base, and legs, pale testaceous. 

 Wings dull hyaline, squamulae and nervures pale testaceous, stigma 

 pale brown, hyaline at the base, touching the 2d cubital areolet ; 

 radial areolet angulated beneath the stigma, seinilunate, the meta- 

 carpus shorter than i of the stigma. Mesothorax smooth and 

 shining, the sutures obsolete. Metathorax punctato-reticulate.
