3932 Tiphia puncticeps sp. nov. 



Length 5 mm. Male. This species is closely related to the foregoing, 

 from which it may be separated thiis: 



I. Front and vertex closely strongly punctured all over; the central 



keel on metanotum reaching to the apex, the area closely striated 

 to near the apex; pronotnm strongly and closely punctured; 

 propleurae strongly punctured throughout, its center not keeled 

 and smooth puncticeps 



II. Pront and vertex not strongly closely punctured all over; the 



central keel on the metanotum reaching to the middle; the area 

 with three or four stout transverse keels on the basal half • pro- 

 notuni weakly pumctured at the base, the apex smooth, the basal 

 slope smooth, impunctate above; propleurae smooth, striated finely 

 at the base only; pygidium smooth and shining in the middle 



on the apical half nevaadan 



The punctuation on the upper part of the head is strong and close 

 all over, except for a smooth space on the sides of the ocelli. Face 

 closely strongly punctured; the clypeus not projecting much, its apex 

 smooth. Mandibles black. Palpi black,obscure testaceous on the apices 

 of the joints. Head densely covered with long white hair. Pronotum 

 strongly punotiired except at the apex, the base above bounded by a 

 stout keel. Propleurae punctured above, the rest except at the apex, 

 sharply striated. Mesonotum and scutellum somewhat strongly closely 

 punctured; the punctuation on mesonotum fine and closer at the apex. 

 Areola on metanotum twice longer than its width at the base; it is 

 narrowed towards the apex, and is irregularly transversely striated. 

 Sides of metanotum aciculated, with some irregular striae; the apex 

 is depressed and has two stout keels in the center, the apical slope is 

 opaque and aciculated. Metapleurae irregularly striated at the apex; 

 the base above with three stout keels. Abdomen shining, thickly 

 covered with long white hair, not very strongly or coarsely punctured; 

 the first segment with a punctured belt on the apex; on the apical 

 segment the punctuation is large deep and close; the last segment is 

 strongly punctured, its sides below hollowed, bordered above the hollow 

 by a stout keel. Apex of radius rounded not projecting beyond the 

 trarusverse cubital nervure, the second recurremt netvure received short- 

 ly beyond the middle; the second transverse cubital nervure is roundly 

 curved in front, and is very little sloped below. Temples oblique, 

 straight. 



3939 Tiphia crenulata sp. nov. 



Black; the hair, spines and calcaria white; the flagellum of antennae 

 inclining to fuscous below; the wings highly iridescent, hyaline, the 

 Btigma and nervures blackish. Head above the antennae closely and 

 Btrongly punctured, more sparsely around the ocelli, more closely below;
