junction of its middle with its basal third, and by the second dorsal 

 segment being at least three or nearly three times as long down its 

 middle as wide at apex. In Zachresta Foerster as represented by 

 the above species the propodeum hardly extends beyond the inser- 

 tion of the hind coxae. Ophionocryptus Schmiedeknecht is manifestly 

 synonymous with Nonnus Cresson. 



PEZOMACHUS (PEZOMACHUS) APANTELICIDA, new species. 



Tyjye-locality . — Japan. 



Type.— Cat. No. 13086, U.S.N.M. 



Female.— Length 3 mm. ; first joint of flagel longer than the second, 

 three times as long as thick in the middle or a httle longer, fifth joint 

 of flagel twice as long as thick in the middle, flagel 16-jointed, the 

 joints excepting the apical joint cyhndrical, antennae stramineous 

 to brownish, head black, finely sculptured, impunctate, brown, 

 blackish posteriorly and along the sutures; thorax finely sculptured, 

 impunctate, brown, blackish posteriorly and along the sutures, 

 legs excepting their tibiae and femora pale stramineous, their femora 

 stramineous, translucent, their tibiae more or less infuscated except 

 at base and in the middle where they are more or less pale stramine- 

 ous; propodeum as long as or longer than the thorax as seen from 

 above, propodeal carinae reduced to a comma-Uke ridge on each 

 side; first, dorsal, abdominal segment gradually broadened out from 

 the base to the apex where it is nearly three times as ^vide as at the 

 base, stramineous, translucent, infuscated basally, second, dorsal 

 segment similar to the first in color, the succeeding dorsal segment 

 black, abdomen impunctate and nearly shining to polished, more 

 or less sculptured with an exceedingly fine reticulation, exserted 

 portion of the ovipositor nearly as long as the first, abdominal 

 segment. 



Allotopotype. — Length somev\diat greater than in the type; first 

 joint of the flagel longer than the second, four times as long as thick 

 in tlie middle, flagel 20-jointed; thorax mostly blackish, apterous, 

 legs colored as in the female except that the hind tibiae are darker; 

 propodeum with its comma-Uke carinae supplemented by a basal 

 carina; first, dorsal, abdominal segment hardly twice as wide at 

 apex as at base, longitudinally impressed, infuscated except for a 

 broad apical band which is stramineous, second, dorsal segment 

 similar to the first in its color scheme; otherwise essentially as in the 

 type. 



In the male paratopoty]3es there is a tendency toward the oblitera- 

 tion of the depression of the first, dorsal segment, toward dark brown, 

 hind femora, darker hind tibige and a greater extent of yellowish on 

 the first and second dorsal segments, than in the type. In the para- 

 types the size varies in either sex down to 2 mm. Seven female 

 and four male paratypes were examined.
