species o/Sphegida3/?'om the Khasia Hills. 225 



Notogonia aciculata, sp. n. 



Black ; covered with a silvery pile ; mandibles dark piceous 

 towards the apex ; palpi dark testaceous and thickly covered 

 with white pubescence. The wings from the transverse basal 

 nervurc distinctly fuscous-violaceous, behind it hyaline. 

 Abdominal segments banded with silvery pubescence ; the 

 pygidium closely punctured and thickly covered with pale 

 pubescence ; the basal ventral segment strongly oblicpiely 

 striated. ? . 



Length 9 mm. 



Front and vertex alutaceous ; ocellus longer than broad, 

 rounded, and having a longish narrow pedicle in front ; frontal 

 furrow deep and obliquely widened above ; the depression, on 

 vertex shallow, indistinct. Pro- and mesonotum coarsely 

 aciculated, the base of metanotum closely transversely 

 striated ; a narrow keel down the middle ; on the sides of 

 the apical slope are oblique, clearly separated strife ; in the 

 centre of the apex is a fl-shaped area indistinctly keeled in 

 the middle. Propleurse aciculated. Mesopleurse distinctly 

 and closely punctured; the metapleurse strongly obliquely 

 striated on the basal half, the apical aciculated strongly and 

 obscurely striated. Apical lobes of sternal process rounded ; 

 the middle furrow is narrow. Second cubital cellule not 

 much more than half the length of the third; the first 

 transverse cubital nervure curved, the second recurrent is 

 received distinctly behind the middle of the cellule, the 

 two are separated by about the length of the front of 

 second cubital cellule. 



Notogonia khasiana, sp. n. 



Length 10 mm. $ . 



Agrees with N. aciculata, but is stouter, the wings not 

 so distinctly hyaline at the base, the second cubital cellule 

 longer compared with the third, the apical slope ot" the median 

 segment is not so distinctly striated, the metapleurae are 

 only indistinctly striated at the base and apex, and the upper 

 half of the first transverse cubital nervure has a straighter 

 more oblique slope. 



Ocellus longer than broad, triangularly produced in front; 

 the lower part of the front, face, and elypeus thickly covered 

 with silvery pubescence. Mandibles obscure brownish in 

 the middle. Pal[)i black, thickly covered with white pubes-
