armatures in the Hymenwpterous genus CoUetes. 55 



strongly with the rounded outline of this part in fodiciis, 

 davicsanus, etc., and allies it rather to succindus. The 

 armature is, on the whole, not unlike that of davlcsamts ; 

 but the apical productions of the " wings" in the sagittas 

 are less marked than in that species. Yet the difference 

 seems to me hardly so great as the figures in Mr. Saunders's 

 synopsis would suggest. 



20. Spectahilis, Morawitz. PI. VII, 20, 20«. 



This is generally called niveofaseiatus, Dours, and I have 

 little doubt that the identification is correct. But I am 

 also convinced that the female at least is that which 

 Morawitz described as spectahilis; and as his description 

 appeared before that of Dours, I adopt his name. 



The forms both of its armature and seventh ventral 

 segment are most peculiar, and distinguish it at once. 

 Radoszkowski has luckily figured the latter along with the 

 armature of his niveofaseiatus; and though the figure is 

 exceedingly rough, its outlines unmistakably indicate the 

 present species. 



As to the armature, it will probably suffice if I call 

 attention to the elongate and attenuated character of all 

 its parts, to the peculiar forceps-like prolongation of the 

 apices of the sagittal " wings," and to the singular appear- 

 ance of the volsella, which is much more prominent than 

 usual — prominent even in the direct dorsal view. 



I know the species from Greece, Italy, South France, 

 and Spain. 



21. Nanus, Friese. PI. VII, 21, 21«. 



This was originally described from specimens, ^ $ and 

 $ $, which I took in Egypt, near Cairo. 



The armature and seventh ventral plate have a certain 

 resemblance (but too slight to cause any confusion) to those 

 of spectahilis. 



The insects themselves have no similarity whatever, and 

 could not possibly be confounded. 



22. Fumilus, n. sp. PI. VII, 22, 22a. 



This is so like the last species externally, that until I 

 dissected them I never doubted that the two were identical ; 

 and Herr Friese himself, on comparing my specimens with 

 his types of nanus, at once declared them to be the same.
