ART. 17 WASPS OF THE GENUS TIPHIA ALLEN AND JAYNES 65 



25, TIPHIA BREVISTIGMA. new species 



Female. — Closely resembles malayaTia^ but differs from it, axjcord- 

 ing to our descriptive notes, as follows : Punctures of vertex largely 

 of first-degree or second-degree density, with several rather broad, 

 irregular, impunctate interspaces; the group of minute punctures on 

 the medio-dorsal line lacking. Third antennal joint slightly longer 

 than its greatest width. Pronotum shagreened. Metanotum broadly 

 impunctate anteriorly. Groove on hind basitarsus vestigia], scarcely 

 half the length of joint. Stigma truncate at apex, less than twice as 

 long as wide, with radius fused with it at its apex. Median carina 

 of the posterior aspect of the propodeum confined to its lower third 

 and not bordered with grooves. Preapical band of first tergite not 

 impressed laterally. First sternite not coriaceous on its constricted 

 base ; lateral grooves plainly complete to escutcheon. Length, 8 mm. 



This species seems to be allied to compressa, from which it may be 

 separated readily by the difference in size and the absence of the un- 

 usual diagonally longitudinal carinae present on the dorsum of the 

 propodeum in cainpressa. 



Male. — Not known. 



DistHhution. — Assam, India.

 Tlphia compressa Smith. Cat. Hymen. Brit. Mus., pt. 3, p. 82, 1855. 



FeTrmle. — Vertex with a few punctures of first-degree density just 

 back of ocelli ; farther back, with punctures of third-degree density, 

 laterally nearly impunctate. Front with pronounced impunctate 

 stripe and interrupted groove; primary punctures very large, densest 

 abov^e antennae, but of first-degree density in all parts except a 

 limited area below ocelli. Clypeal extension impunctate for nearly 

 half the distance from its apex to base of antennae. Flagellum of 

 antenna fulvous beneath. Pronotum polished ; its primary punctures 

 very large, and of first-degree density in all parts except a small 

 area antero-medially to which the small, sparse secondaries are con- 

 fined ; discal band not well defined ; medially, the punctate area dis- 

 tinctly narrower than the impunctate. Side of pronotum with a 

 shallow, curved groove extending about half way across the middle, 

 with numerous widely separated punctures on the upper half. 

 Metanotum with its sparse primaries nearly as large as those of 

 scutellum. Legs with major calcarium of hind tibia tapering gradu- 

 ally from the base; hind basitarsus with vestigial groove scarcely 

 one-fifth length of joint and becoming shallower apically; on out- 

 side with group of three to four long, curved spines, with one at 

 apex. Wings with first cubital mark vaguely defined. Propodeal
