being smaller, and in the bodies not being metallic green 

 or blue as in the species which have usually been regarded 

 as typical oi AmpiileXy e.g., A. compressa, and A. angtisticollis. 

 They are, indeed, so unlike that it is probable that an 

 examination of all the species of R/nnopsis might reveal 

 some other generic distinction besides the difference in the 

 neuration, in which case the name Ampitlex would be 

 retained for the European species and for Rhmopsis (which 

 must, in this case, be regarded as a synonym of Ampidex), 

 while a new name would be required for the large metallic 

 exotic species {covipressa^ &c.). 



The only known European species of Ampulex is A. 

 fasciata, Jurine (Nouv. Meth. d. Class, d. Hym., pi. xiv., 

 supp.) = ^?/r^/^^, Giraud (Verh. z.-b. Ges., Wien, 1858, p. 41 1 ). 

 This is totally black and differs otherwise in many respects 

 from A. ruficollis. 



GORYTES TRICHIOSOMA, Sp. 710V. 



Niger, dense longe Jiirtiis ; pnnctatiis, apice metanoti reti- 

 culato; alls fusco-Jiyalinis. Long. 12 — 13 mm. 



Hab. New Zealand, Greymouth, (^Helms). 



The hair on the head and thorax is fuscous-black, long 

 and rather dense ; on the base of the abdomen it is equally 

 long, but sparser ; the hair on the rest of the abdomen is 

 shorter and thicker. Head and thorax closely and distinctly 

 punctured, shining ; the posterior part of the mesopleurae 

 almost impunctate ; there is a large, somewhat triangular 

 impunctate space at the base of the metanotum, the rest of 

 the metanotum being irregularly rugose, running into reti- 

 culations at the apex. Abdomen semi-sessile; shining; the 

 petiole depressed in the centre at the base ; the basal three- 

 fourths with an oblique slope, the apex on a level with the 

 second segment. There is a shallow, but distinct, furrow 

 at the base of the latter, this furrow being irregularly crenu- 

 latcd. Apical segment acutely triangular, punctured like
