ART. 17 WASPS OP THE GENUS TIPHIA ALLEN AND JAYNES 95 



mary punctures. Pygidium densely reticulo-punctate on basal three- 

 fifths; apical section plainly wrinkled longitudinally on either side 

 of the impunctate emargination. Length, 11 mm. 



Mole. — Not known. 



Distribution. — Kiangsi, China. 



Type.— Ciit. No. 41808, U.S.N.M. Female, Ruling, China, July 11, 

 1926 (Wong). 



Paraiype- — Retained in the collection of the Japanese Beetle Lab- 

 oratory : One female of the same lot as the type. 



The sting sheaths of the two specimens examined are unusually 

 exserted to distance equal to width of pygidium, and the two associ- 

 ated accessory processes for nearly half the distance. Whether this 

 condition is normal or not can not be stated, but if so it furnishes a 

 rather good diagnostic character. 



42. TIPHIA NANA, new species 



Male. — Vertex with punctures small, poorly outlined, everywhere 

 of third-degree density, though denser back of ocellar triangle and 

 near the eyes. Front faintly shagreened below; primary puncturei 

 clearly outlined, nearly everywhere of third-degree density except 

 near the lower eye orbits; preocellar area broad, with interspaces 

 laterally at least twice the width of an ocellus ; secondary punctures 

 not apparent. Antennocular distance less than the width of antennal 

 fossa. Clypeal extension with its apical width one and one-fourth 

 times clypeoantennal distance, abruptly emarginate, sparsely coarse- 

 punctate to apex, disk slightly convex. Pronotum with its dorsum 

 sparsely punctate with small primary punctures of uniform third- 

 degree density, the impunctate hind margin nearly reaching the 

 transverse carina medially ; secondary punctures lacking ; side with a 

 faint, curved groove extending two-thirds the distance to alar angle. 

 Mesepisternum sparsely fine-punctate, with secondary punctures not 

 clearly differentiated on the outer, convex disk. Scutellum with im- 

 punctate apex nearly as wide as the largest primary punctures. 

 Metanotum with apical callosity, its sparse primary punctures as 

 large as the largest on the scutellum. Wings hyaline; radial cell 

 greatly exceeding second cubital cell. Propodeum with its areola 

 convergent and straight-sided, length one and one-half times its 

 width, enclosed area smooth and flat; side with its upper portion 

 scarcely rugose, not clearly differentiated from the lower shagreened 

 portion. First tergite with a preapical band in a shallow concavity 

 marked posteriorly by a single row of small, poorly outlined primary 

 punctures. First sternite not coriaceous, with lateral grooves on 

 posterior half and a strong median keel on anterior half. Intermedi- 

 ate tergites faintly shagreened; the primary punctures very small
