Ueber Ampulex Jur. (s. 1.) und die damit enger verwandten Hymenopteren-Gattungen. AQQ 



»Female. Length lo lines. Brilliant purpIe, with shades of violet and green; the 

 anterior femora and tibiae in front, and the intermediate and posterior femora, ferru- 

 ginous; the anterior wings with a faint cloud crossing them bevond the Stigma; the 

 Vertex, pro- and mesothorax finely and very sparingly punctured; the metathorax with 

 finc longitudinal carinae, the intermediate spaces transversely striated; the abdomen 

 tinged with green at the apex. 



»Hab.: Makassar. 



»This species so closelv resembles Ampulex compressa that perhaps it will be 

 rcgarded bv some persons as only a local varietv; I have separated it for the following 

 rcasons: in the Hrst place, the head is rounded behind, whereas in A. compressa it is 

 transverse with the angles obtuse, and the eves are more closely approximate than in 

 that species; the second lateral carina on the rnetathorax is simple, while in A. com- 

 pressus it becomes double towards the apex: all the specimens from Makassar are bril- 

 liant purple in both sexes.« 



52. Ampulex rußcollis Cameron. 



Ampulex rußcollis Cameron, Mem. Proc. Manch. Lit. Phil. Soc, I (4. ser.), 



pag. 178 1888 



»Niger, thorace rufo, tnetanoti medio nigro; mandibulis rufo-flavis; pedibus an- 

 terioribus ex parte rufis; alis hyalinis, fusco fasciatis. Long. 7 mm. 

 »Hab.: Gibraltar (J. J. Walker, R. N.). 



»Head semi-opaque, closely punctured; the carinate face transversely striated; 

 almost bare, except a fringe of white hair over the mouth, which is testaceous. Anten- 

 nae bearing a sparse microscopice pile; the scape and the middle joints beneath rufous; 

 the third Joint twice the length of the fourth. Prothorax finely rugose.; mesonotum ob- 

 scurelv punctured; mesopleurae closelv punctured, striolated in front; the sternum 

 covered with long white hair; metanotum with a central and three lateral keels; reti- 

 culated, the sides irregularly striolated; median segment semi-perpendicular, transver- 

 sely striated, thickly covered with white hair. Abdomen shining, impunctate, the apex 

 thickly covered with silvery white pubescence. The anterior coxae, trochanters, and 

 the femora, tibiae and tarsi in front, the four posterior trochanters, and the middle 

 femora in front are reddish; the frons 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 Ampulex and Doli- 

 chiirus. 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 upwards; but as there is some Variation in this in 

 the known species of Ampulex, this can hardly be considered of much importance. 

 There is also one cubital cellule less, the first transverse cubital nervure being oblite- 

 rated. 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 Ampulex, 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 difference; and if the neuration of .-1. rußcollis be normal, i. e.,
