irregularly striated ; on the sides of apex arc four oblique 

 kecb. Pleurae aeiculatcd ; tlie base and apex of the meta- 

 plcurae with a few oblique keels. Sternum thickly covered 

 with silver}' pubescence; the process bluntly triangular on 

 the sides at the apex ; the central part has the basal half 

 distinctly dilated. "Wings fuscous-violaceous ; the second 

 cubital cellule is, if anything, shorter than the first ; the 

 first transverse cubital nervure is obliquely bent from shortly 

 below the middle; the second recurrent nervure received 

 shortly beyond the middle of the cellule ; the two nervures 

 are separated by the length of the top of the second cubital 

 cellule. Legs and abdomen pruinose; the ])ubescence on 

 the pygidium bright fulvous ; the leg-spines blackish. 



Notogonia vivax, sp. n. 



Black; the body and legs covered with silvery pubescence, 

 the leg- spines black ; wings hyaline, with a slight but distinct 

 yellowish tint, the apex smoky ; the costa, stigma, and 

 nervures testaceous, the apical nervures darker ; the second 

 cubital cellule in front half the length of the third ; the 

 recurrent nervures received behind the middle and separated 

 by slightly less than the length of the second cubital cellule 

 in front. Pile on pygidium silvery, with a slight golden 

 tint ; the hypopygium closely and distinctly punctured. ? . 



Length 12 mm. 



Front and vertex alutaceous; the ocellus rounded behind, 

 in front produced into a process as long as itself, the furrow 

 below it deep. INIesonotum alutaceous, the pile with a 

 yellowish tint ; propleune stoutly irregulai-ly striated in the 

 middle. Median segment alutaceous, the apical slope 

 transversely striated, the striae on the lower part finer than 

 on the upper. Metapleurse finely and closely obliquely 

 striated. 



This species has the yellowish-hyaline tinted wings of 

 N. tristis and N. jaculatrix : the former may readily be 

 known by the reticulated median segment ; the latter is a 

 larger and stouter insect, has the second cubital cellule on 

 the top longer compared with the third, the tibial spines are 

 shorter and rufous, not black, the pubescence on the front 

 longer and denser, and the ocellus lias only a short pro- 

 jection in front. 



Notogonia tegularis, sp. n. 



Black ; the cheeks, face, and clypeus thickly covered with 

 silvery pile; the front and vertex Avith fuscous hair; thorax
