ART. 17 WASPS OF THE GENUS TIPHIA ALLEN AND JAYNES 77 



Projjodeal areola subrectangiilar ; lower portion of side polished, 

 shagreened, with barely perceptible hairs posteriorly; posterior as- 

 pect inconspicuously coriaceous, with the median carina faintly de- 

 veloped on lower half or less. First tergite w^ith its preapical band 

 abruptly impressed on anterior border, not much expanded laterally, 

 marked posteriorly by a moderately regular row of clearly outlined 

 primaries. First sternite with lateral grooves on posterior half and 

 a faint median keel anteriorly. Tergites 3 to 5 with rather fine, 

 poorly outlined punctures; impunctate margin medially scarcely 

 three times width of largest adjacent primary punctures. Length, 

 5 to 6.5 mm. 



The male differs from merica-e in having the preapical band wider 

 and shalloAver, with its posterior punctures much less coalesced, and 

 from malayana in having the front, mesepisternum, and tergites less 

 strongly shagreened, the punctures of the median vertical patch 

 denser and less clearly outlined, the primaries of the mesepisternum 

 less numerous, the secondaries more numerous, and the radial cell 

 less conspicuously extended. 



Distribution. — Hyogo, Kanagawa, and Iwate, Japan; Keikido. 

 Chosen; Fukien, China. 



The foregoing notes are based upon a selected female specimen 

 from Suigen, Chosen, July 25, 1923 (Sato), Clausen No. 1852, not 

 reared, and on the following specimens in the collection of the United 

 States National Museum and the Japanese Beetle Laboratory: From 

 Yokohama, Japan, 8 females. May 17, 1920 (Clausen), Clausen No. 

 1382; 1 male, September 15, 1921 (Clausen). From Morioka, Japan,

 females, August, 1925 (Gardner), used in breeding, Gardner No. 1; 

 1 female, August 12, 1925 (Sato), Gardner No. 1; 1 female, Septem- 

 ber 6, 1925 (Sato), Gardner No. 1; 3 females and 1 male, insectary 

 reared, Riverton Exp. 214; 4 females and 2 males, insectary reared, 

 Riverton Exp. 314. From Kuliang, China, 1 female, August 6, 1925, 

 labelled F 1. 



Representative specimens have been deposited in the collections of 

 the British Museum, the Illinois Natural History Survey, and the 

 Philadelphia Academy of Natural Sciences. The association of sexes 

 is the result of breeding work. The specimens in Riverton experi- 

 ment 214 were derived from field-collected females from Suigen, 

 August, 1925, and those in Riverton experiment 314 were derived
