IJymenopterous Genus Tiphia. 125 



to spread over the whole of India and Burma. T. erythro- 

 cera, Cam., from Masuri, has only three carina? on the median 

 segment and may perhaps prove to be distinct, but as the 

 development of the intermediate carina? shows a good deal of 

 variation, I think it will probably prove to be at most a local 

 variety.

This will probably prove to be the male of T. polycarinata 

 as Nurse suggests. Walker's type is from Ceylon, and 

 agrees well with a specimen from Burma. The stigma is 

 almost black in the type of decrescens and ferruginous in 

 nervosa, but other specimens show intermediate gradations. 

 The stigma is said by Magretti to be small, but in specimens 

 I have seen it is rather large. 



Tiphia fulvicornis, sp. n. 



? . Clypeus narrowly truncate at the apex, finely punc- 

 tured at the base, broadly smooth at the apex. Head 

 shining, closely but not very deeply or coarsely punctured 

 on the front, more sparsely on the vertex and round the 

 ocelli. Antennae inserted twice as far from the eyes as from 

 each other ; the scape shining, finely and closely punctured 

 above, with pale fulvous hairs beneath, the second joint of 

 the flagellum very slightly longer than the first, the third 

 half as long again as the second. Pronotum rather sparsely 

 punctured, the posterior margin smooth, the propleura? smooth 

 and shining, very finely and obscurely longitudinally striated 

 on the lower margin ; mesopleurse rather sparsely punctured ; 

 scutellum shining, sparsely punctured, with a very fine, 

 obscure, longitudinal sulcus in the middle. Median segment 

 opaque, coriaceous, smooth and shining at the posterior 

 angles, rectangular, nearly half as broad again as long, 

 moderately convex in the middle, the lateral and posterior 

 margins slightly raised, forming fine carina ; the posterior 

 truncation almost vertical, shining and very finely aciculated ■ 

 the three longitudinal carina? on the dorsal surface parallel, 

 not very near together, the median one not quite reaching 

 the apex. Abdomen shining, rather finely punctured, much 

 more sparsely on the two basal segments than on the others,
