Odynerus {Leionotus) miniatus, Saiiss.

(1854).

(1870). 



A comparison between the types of tlicse two insects, both 

 of which are iu tlie British ^luseum, leaves no doubt that 

 tliey are the same. Both were described from India. 



Odynerus hottentottus, Sauss. 



Odynerus hottentotttt^, Saus.*. 6t. Fam. Vesp., Suppl. p. 244 (1856). 

 Odynerus eryfhrospilus, Cam. Record Albany Mus. 



Cameron's species is described from Dunbrody in Cape 

 Colony : Saussure's species came from the Cape of Good 

 Hope. 



Odijnerus simplicipes, Cam. Trans. Amer. Ent. Soc. 

 xxxi. p. 380. 



This species, described from Mexico, is certainly not an 

 (Mynerus. The neuration of the fore wing is that of 

 Saussure's Section I. (Etudes sur les Vesp. i. p. xxix). As 

 there is only one specimen and the mouth-parts are not 

 visible, it is impossible to ascertain its true position, but it 

 bears no resemblance to the other genera of this section, of 

 which no species appear to have been described from Central 

 America. 



I do not adopt Schulz's new name of Odynerus vicarius 

 (' Spolia Hymenopterologica/ p. 219), since the insect will 

 have to be removed from Odynerus. 



Odynerus {Leionotus) moultoni, sp. n. 



Niger, rugose punctatus ; clypeo mandibulisque flavo-maculatis ; 

 anteniiis, pedibus, abdominis segraentorum margine postico 

 fcrrugineis ; alis laete flavo-hyalinis. 



(^ . Black ; a subtriangular mark reaciiing to the trun- 

 cation of the clypcus, the scape beneath, a small spot at the 

 base of the mandibles, yellow. Flagellum, legs, and apical 

 margin of all abdominal segments dark ferruginous. Wings 

 rich golden hyaline. Clypcus as broad as long, truncate at 

 the a{iex. Pronotum truncate, produced to form a sharp 

 angle on either side of anterior margin, and gradually 

 widening towards the tegulae. Scutellum and postscutellum 

 of almost equal size, tiie latter broadly subtriangular, median 

 segment concavo-truncate. Abdomen : first abdominal seg-
