no. 2173. A REVISION OF THE BEMBWINE WASPS— PARKER. 1 1 



The wings are hyaline and the veins brown. The body and the 

 basal joints of the legs are covered with moderately dense white 

 pubescence, longest on vertex, at base of mandibles and on posterior 

 part of median segment. Pubescence of the abdomen except on 

 base of first segment is much shorter than elsewhere on the body. 

 The flagellum, except two basal joints, is reddish below darkening 

 toward the apex and is slightly carinate posteriorly on segments 7-11, 

 the carina inclosing small longitudinal pits. The second sternite 

 bears a well developed process and the eighth ends in three curved 

 spines of which the central, longer one has, arising from its base 

 beneath, a fourth spine, short, stout, pointed and obliquely directed 

 backward. 



The female is quite similar to the male in general appearance and 

 color markings. The lower surface of the flagellum is somewhat 

 lighter and the yellow, especially on the scutum and the abdomen, 

 is somewhat more extensive, consequently fewer of the fasciae on 

 the tergites are interrupted medially and the median paired spots 

 less frequently completely formed. The yellow on the sternites is 

 also more extensive. In some specimens the black is limited to a 

 medial spot on the second and narrow basal borders on sternites 3-5. 

 The ultimate segment is yellow apically with a deep median anterior 

 notch above and a less evident one below, and its tergite basally 

 bears at the sides a cluster of short stout spines. 



Length. — 14-18 mm. 



In the last volume of his monograph, page 965, Handlirsch places 

 duplicata Provancher as a probable synonym of scolopacea Hand- 

 lirsch, giving as his reasons for so doing the fact that the two descrip- 

 tions were published at about the same time and that he could not 

 determine from Provancher's description whether it was based upon 

 scolopacea Handlirsch or tibialis Handlirsch. I cannot accept this 

 contention. The description of duplicata Provancher, which appeared 

 in the issue of Le Naturaliste Canadien for November, 1888, was 

 published prior to that of scolopacea Handlirsch. Provancher's 

 type is what is known to entomologists in America as duplicata; it 

 is not tibialis Handlirsch. It, therefore, can not by any possible 

 means be made a synonym of scolopacea Handlirsch and must stand 

 as a good species. As far as it is possible to judge from the descrip- 

 tion of scolopacea given by Handlirsch his species is identical with 

 Provancher's duplicata.
