PHYTOPHAGOUS AND PARASITIC HYMBNOPTERA. 127 



deeper rufous colour ; by the transverse median nervure in hind 

 wings being broken lower down, by the scutellar keels not converging 

 at the apex, by the temples being more largely developed and not so 

 obliquely narrowed, and by the metapleural keel being much more 

 broadly developed, especially at the base. Antennse dark rufous, 

 darker towards the apex. 



Pundalu-oya, October. 



Paniscus ceylonicus, Cam., is a much larger (nearly 25 mm.) and 

 stouter species than the two I have described here ; the stigma is 

 dark fuscous ; the disco-cubital nervure is broken distinctly by a 

 stump of a nervure ; the recurrent nervure forms two rounded curves, 

 the upper being more broadly rounded, while in those here described 

 it forms one curve only. 



37. — Paniscus loevis, sp. nov. 



Pallid yellow, entirely smooth and shining ; the antennae with a 

 rufous tinge, not darkened towards the apex, wings hyaline, the 

 stigma paUid yellow, the ner vures blackish, ?. 



Length 8 mm. 



Kandy, July. 



This species differs from the other Oriental species in being perfect- 

 ly smooth, the head and thorax being impunctate and the metano- 

 tum not striated. It differs also in the transverse median nervure 

 being received at a greater distance from the transverse basal, and 

 the eyes below are separated by the same distance as they are at the 

 top, while in the others, e.g., orientalis a,nd intermedius , the distance 

 is clearly greater below than it is above. The parapsidal furrows, 

 too, are much less strongly indicated. 



The scutellar keels do not unite at the apex. Apex of clypeus 

 rounded ; above it is not separated from the face. There is no 

 malar space, the eyes touching the base of the mandibles. Temples 

 distinct, obliquely narrowed. Transverse median nervure in hind 

 wings broken close to the bottom of the upper fourth, the lower part 

 with a more sharply oblique slope than usual. The antennae are 

 much more densely pilose than usual, the pile being close, long, and 

 white. The metasternal keel is wider at the base than at the apex. 

 It is a more slenderly built species than the others. 



38. — Campoplexgreeni, sp. nov. 



Black, the third, fourth, and fifth abdominal segments red ; the 

 apex of the fore femora, tibiae, and tarsi testaceous ; the middle 

 femora near the apex and the tibiae more broadly at the base.
