Hymenopterous Genus Tiphia. 119 



shining, the mesopleurae finely and rather sparsely punc- 

 tured. Mesonotura and scutellura rather sparsely punctured, 

 the tegular smooth and shining. Median segment short, 

 very broadly emarginate at the apex, subopaque, the median 

 carina reaching the apex, with one on each side of it, the 

 last two converging towards the apex, where they are sepa- 

 rated by a distance equal to about two-thirds of that which 

 separates them at the base; there is also a more obscure 

 carina on each side, rather less oblique than in the female, 

 and reaching the apical margin at a distance from the apical 

 angle equal to that by which the two outer carinas of the 

 median series are separated from each other on the apical 

 margin, the space between the carinas very finely rugulose ; 

 the surface of the posterior truncation slightly concave, 

 smooth and shining ; the sides of the segment are coarsely 

 striated. Abdomen shining, the two basal segments and the 

 base of the third smooth, the apex of the third and the whole 

 of the remaining segments finely and closely punctured and 

 clothed at the sides with fulvous pubescence, the basal 

 segment with a deep, longitudinally-striated transverse sulcus 

 near the apex ; a similar but deeper sulcus at the base of the 

 second segment. The transverse median nervure is received 

 very distinctly behind the transverse basal nervure; the 

 recurrent nervure is received near the apex of the second 

 cubital cell. 



Black ; the mandibles at the apex, the palpi, the apex of 

 the femora, and the anterior tarsi fusco-ferruginous. Wings 

 very light fusco-hyaline, hyaline at the base; nervures 

 fuscous, the stigma black. 

 Length 7 mm.

T. clavinerva, Cam. Ann. & Mag. Nat. Hist. (7) xiii. 

 p. 281, 1904, J 1 , is extremely near to this species and may 

 prove to be a synonym, but as there are slight differences in 

 the sculpture and neuration it is better not to sink the name 

 until more specimens are available. The carina on the first 

 ventral segment is the same in both species. Tiphia robusta, 

 Cam., will probably prove to be a variety of the female; 

 specimens from Lower Burma and Siam, which I refer to 

 compressa, are without the lateral dorsal carinae on the 

 median segment and show only the three usual carinas on 

 the middle.
