ON SOME NEW GENERA AND SPECIES OF HYMENO- 

 PTERA (ICHNEUMONID^, CHRYSIDID^, FOSSORES, 

 AND APID.E).

ICHNEUMONID^. 

 Amblyjoppa, gen. nov. 



Antennae stout, slightly compressed and dilated between the middle 

 and the apex. Scutellum roundly convex, raised above the level of 

 the mesonotum ; its sides not margined, the apex with a flat, oblique 

 slope. The base of the median segment has a distinct oblique slope ; 

 the areola is somewhat horseshoe-shaped, slightly narrowed behind ; 

 it is flat, raised, smooth and shining ; the sides, except at the apex, 

 are furrowed, the farrows becoming wider and striated towards the 

 apex ; the posterior, median, and the spiracular areae only are clearly 

 defined ; there are no spines or projections, and the apex of the 

 segment has a gradually rounded slope. Areolet narrowed at the top. 

 Abdomen closely punctured ; the segments are closely punctured and 

 do not project much at the apex laterally. Legs stout; the apex of 

 the hinder femora does not extend beyond the third segment. The 

 post-petiole is wide and clearly separated; on the second segment only 

 the part between the gastrocoeli is striated. The abdomen is com- 

 paratively short, being not much longer than the head and thorax 

 united ; its apex is bluntly pointed and broad ; it is not quite half the 

 length of the penultimate ; the ovipositor is broad and projects. 



The temples are obliquely and rather sharply narrowed ; the 

 occiput is roundly incised, and is sharply margined ; the malar space 

 is large ; the apex of the clypeus is transverse ; the labrum slightly 

 projects ; the second joint of the maxillary palpi is widely dilated ; 

 the mesopleural tubercles are long, narrow, and plate-like ; the ventral 

 keel extends on to the fourth segment, and is not very distinct. There 

 is a short stump of a nervure on the cubital-disco nervure. The wings 

 are dark-coloured. 



The species I have included in this genus are large handsome 

 insects. The characteristics of the genus are the roundly convex 

 scutellum and the flat, raised, smooth and shining areola. The 

 median segment is completely areolated ; there are three basal 

 and five apical areae, besides the spiracular area. The basal 

 joints of the flagellum are elongated, more than three times 

 longer than wide ; the transverse median nervure is not quite 

 interstitial ; the transverse cubital nervures may be distinctly 

 separated above, or they may be almost united. 



To this genus belongs " Iclmeamon" (elvanus, Cam.,* which 

 appears to be a common Indian species.
