n-eio Species of Diploptera. 101 



Odynerus [Leionotus) miniatus, Sauss. 



Odynerus (Leionotus) miniatus, Sauss. Et. faui. Vesp. Suppl. p. 249 



(1854). 

 Pterochilus pulchellus, Smith, Trans. Soc. Zool., Lond. vol. vii. (3) p. 190 



(1870). 



A comparison between the types of these two insects, both 

 of which are in the British Museum, leaves no doubt that 

 they are the same. Both were described from India. 



Odynerus hottentottus, Sauss. 



Odynerus hottentottus, Sauss. ^t. Fam. Vesp., Suppl. p. 244 (1856). 

 Odynerus erythrospilus, Cam. Record Albany Mus. 



Cameron's species is described from Dunbrody in Cape 

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

 Hope. 



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

 xxxi. p. 380. 



This species, described from Mexico, is certaiuly not an 

 Odynerus. 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 sectiou, 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 ; 

 antennis, pedibus, abdominis segmentorum margine postico 

 ferrugineis ; alis laete flavo-hyalinis. 



cJ . Black ; a subtriangular mark reaching to the trun- 

 cation of the clypeus, 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. Clypeus as broad as long, truncate at 

 the apex. Pronotum truncate, produced to form a sharp 

 angle on either side of anterior margin, and gradually 

 widening towards the tegulse. Scutellum andpostscutellum 

 of almost equal size, the latter broadly subtriangular, median 

 segment concavo-truncate. Abdomen : first abdominal seg- 



o 



ment massive, broader than long, as broad as the second
