that of the interspaces and equalling the size of the largest primaries 

 of the scutellum. Tegula plainly shagreened. Wings with first 

 cubital mark clearly defined; radial cell equalling the second cubital 

 cell. Propodeum with its areola one and one-fourth times longer 

 than broad, sides convergent, rounded at apex where carinae are 

 thickened, median carina expanded, and tapering to lowest fourth 

 of areola, enclosed area flat and polished; lower sides with the an- 

 terior part finely striate and the posterior part minutely setulose; 

 posterior aspect without medial carina. First tergite with preapical 

 band not impressed, consisting of distinctly separate punctures about 

 three rows wide. First sternite with disk densely covered with 

 minute punctures, constricted half with shallow primary pmictures 

 and a median keel ; apical sulca not well developed ; lateral grooves 

 absent. Second tergite with a single row of large apical punctures; 

 tergites 3 to 5 with punctures becoming large toward apices, and 

 with numerous minute but deep secondary punctures with sharply 

 delined outlines scattered widely on posterior halves, apical primary 

 punctures separated from apices of segments by distances much less 

 than their diameters, and marked by even rows of conspicuous, yel- 

 lowish hairs. Sternites two to five with apical rows of yellow hairs 

 similar to those of dorsum; fifth sternite with its lateral denticle 

 a strong, conspicuously elevated tooth, mediad of which there is 

 a large orifice; fourth sternite with a vestigial orifice in a similar 

 position. Length 14 mm.

11. TIPHIA SINGULARIS. new species 



Male. — Vertex with punctures back of and between ocelli and near 

 inner margins of eyes of second-degree density. Front shagreened, 

 with median carina well developed; primary punctures large, on 

 anterior half from eye to eye their diameter very much exceeding 

 width of narrow interspaces; area of punctures of first-degree den- 

 sity extending upward on sides to level of lowest ocellus ; secondary 

 punctures sparse on lower third. Antennocular distance greater 

 than the* width of antennal fossa. Clypeal extension with its apex 

 shallowly emarginate, having a narrow, impunctate margin of uni- 

 form width ; disk conspicuously shagreened ; clypeoantennal distance 

 equal to apical width of extension. Pronotum shagreened ; primary 

 punctures large and shallow, in a vague series of second-degree den- 

 sity, somewhat denser laterally; several secondary punctures in 

 medio-anterior region. Sides of pronotum with a well defined, nar- 

 row median groove ; disk finely striate above, and with large, round 

 punctures at the alar angle. Mesepisternum faintly shagreened;
