HYMENOPTERA NEW TO CEYLON. 123 



the eyes and on the under parts of the head, while on the clypeus at 

 the sides and front and on the labrum it forms a thin fringe. Thorax 

 covered somewhat densely with long brown hairs above, on the sides 

 below extending on to the sides and posterior face of the median 

 segment. Legs almost bare, the tibiae and tarsi clothed and out- 

 wardly fringed with long whitish hairs ; tibial calcaria yellowish 

 white, preceded on the inner side of the tibiae of the anterior and' 

 intermediate legs by a yellowish white curved robust hook and on 

 the tibiae of the posterior legs by a similar larger brown process or 

 hook. There is a further armature on the inner side of the femora 

 at base of a short thick blunt tooth. Claws bifid. Wings hyaline, 

 'nervures dark brown. Abdomen in the two males before me almost 

 bare of pubescence, only the basal face of the abdomen, the sides, 

 and apical margins of all the segments above and below fringed 

 with brownish hairs. This absence of pubescence is evidently due 

 to attrition ; in fresh specimens the pubescence is probably fairly 

 abundant. The whole head, thorax, legs, and abdomen beneath 

 the covering of hair very minutely and closely punctured. , 

 Length 6 10 ; exp. 19 mm. Habitat, Colombo, Ceylon. 



This is a very distinct form, not closely allied to any Indian 

 Podalirius known to me. It more nearly resembles the European 

 P. senescens (Lepel) in general appearance, but the armature of the 

 legs distinguishes it at once from any form known to me. 



Oryssus (Mocsarya) metallicus, Mocsary. 



Oryssus metallicus, Mocsary, Termesz. Fuzetek, XIX., 1896, 

 pi. 1, fig. 2?.

 p. 608 ?. 



It seems strange that this beautiful insect , described from the 

 Sunda Islands by Mocsary, should occur also in Ceylon, but a Ceylon 

 specimen of an Oryssus kindly submitted to me for examination by 

 Mr. 0. S. Wickwar corresponds so closely to Mocsary 's description 

 of 0. metallicus that without an actual comparison with Mocsary's 

 type I do not like to describe it as new. 



So far as I can make out from Mocsary's description and plate, 

 the Ceylon insect differs only as follows : — 



Forewing : the fuscous cloud much paler, without purple reflections 

 and limited to the apex of the wing extending into the apex of the 

 radial cell, but not into the cubital cells. Legs nearly black, tarsi 

 of all the legs bright orange red, posterior femora and tibiae dull 

 dark, not bright, red. 



Professor Konow has split up Latreille's genus Oryssus into four 

 genera, making 0. metallicus the type of his new genus Mocsarya.
