DESCRIPTION OF SPECIES OF HYMENOPTERA. 1005 



side of the ocelli ; the space between the ocelh is more closely punctured and 

 is depressed and distinctly furrowed in the middle. Face and clypeus closely 

 rugosely punctured and covered thickly with silvery pubescence ; the apex 

 of clypeus fringed with golden hair. Mandibles black, rufous fit thp apex. 

 Thorax thickly covered with long white hair ; the hair on the meso- 

 notum, scutellum and post-scutellum is fulvous ; on the mesonotum it is much 

 sparser and paler ; it does not hide the punctuation which is close and strong ; 

 the apex of the pronotum is raised into a thin plate, which is widely and deeply 

 incised in the middle ; the incision is narrowest in the centre. The median 

 segment is rugosely punctured, more finely and closely in the middle than on 

 the side3 ; the basal area is irregularly and not very closely longitudinally 

 striated. The hinder tibiae become gradually thicker towards the apex ; the 

 2nd joint becomes gradually wider from the top to the bottom ; its upper 

 part projects ; the calcaria are closely covered with stiff hairs, almost pectinated. 

 The basal segments of the abdomen are piceous in the middle, dorsally and 

 ventrally, and have their apices broadly banded with pale bright fulvous 

 pubescence. The pygidial area is densely covered with bright golden pubes- 

 cence, except on the centre and towards the apex. 



Megachih pliaola, sp. no v. 



Nigra, dense albo-pilosa ; abdominis basi femoribusque posterioribus supra 

 rufis ; alis hyalinis, stigmate fusco. $ 



Length : 6 mm. 



Habitat. — Deesa. 



Antennae long, nearly 3 times the length of the head ; the basal two joints 

 black ; the flagellum brownish beneath ; the apical joints are slightly dilated 

 below. The clypeus, face and lower part of the front are densely covered 

 with white hair ; the vertex and upper part of the front sparsely covered with 

 longish fuscous hair ; the lower orbits and the lower part of the head are 

 covered with long white hair. Front and vertex closely, uniformly and stronglj 

 punctured. The base of the mandibles is strongly and deeply punctured ; the 

 apex is bidentate : the upper tooth is smooth, depressed and shining ; the lower 

 part is deeply and widely furrowed. Thorax closely punctured and thickly 

 covered with white hair ; the basal area of the median segment is coarsel.1 

 shagreened, more coarsely at the base than at the apex ; across the base is a 

 wide, not very deep, furrow. Wings clear hyaline ; the stigma is lighter in 

 colour than the nervures, the 2nd recurrent nervure is received , nearer the 

 transverse cubital than is the first, but is not interstitial. Tegulse piceous ; 

 their base is thickly covered with white pubescence. Legs black, thickly 

 covered with white hair ; the 4 hinder femora are for the greater part beneath 

 brownish, as are also the greater part of the basal joint of the tarsi and the 

 apices of the other joints. Abdomen black ; the basal segment, except in the 

 middle at the apex, rufous ; all the segments are fringed at the apex with white 

 pubescence ; they are distinctly, but not very strongly, punctured ; the last 

 segment is widely furrowed in the middle ; the ventral segments are rufous.
