Hynicnoptera. 1 79 



trochanters, and the femora, tibiae and tarsi in front, the 

 four posterior trochanters, and the middle femora in front 

 are reddish ; the front femora are only black in the middle 

 behind. The wings are very clear hyaline ; the cloud 

 extends from the base of the stigma to the end of the third 

 cubital cellule. The hind coxae are densely covered with 

 silvery pubescence. 



The only genera in which this species can be placed are 

 Auipiilex and DolicJmriis. Comparing it with the Indian 

 species of Ampulex, the only tangible point in which it 

 differs (that is of what might be regarded as of generic 

 value) is that the petiole is thicker and curves more up- 

 wards ; but as there is some variation in this in the known 

 species oi ADipulex^ this can hardly be considered of much 

 importance. There is also one cubital cellule less, the first 

 transverse cubital nervure being obliterated. Also in this 

 respect the oriental species are said to vary in this nervure 

 being occasionally faint. In the form of the abdomen it 

 probably more resembles Dolichurus ; but in that genus the 

 first recurrent nervure is received in the second cubital 

 cellule. As in Ampiilex, there is a tooth towards the middle 

 of the claw. In the neuration of the wings I may add it 

 agrees with the genus Rhinopsis, West, (an American genus). 

 A careful comparison of it with a Central American species 

 of Rhinopsis does not show any appreciable generic diffe- 

 rence ; and if the neuration of A. riificollis be normal, i.e., 

 if there are only two transverse cubital nervures, I do not 

 see how it can be separated from Rhinopsis.^ and must, in 

 fact, be regarded as pertaining to that genus, unless, indeed, 

 the difference in the neuration between the latter and Ain- 

 pulex be not regarded as of generic importance, in which 

 case the two may be united. 



It is, however, worthy of note that this and the only 

 described European species oi Ainp2ilex\\-d.\'^ only two trans- 

 verse cubital nervures as in Rhinopsis, Further, they differ in
