NO. 2173. .1 REVISION OF THE BEMBWINE WASPS^PARKER. 85 



anterior orbits, which may be lacking, narrow posterior orbits, which 

 also may be lacking, lateral spots on tergites 1-4 or 1-5, lateral spots 

 on stemites 2-4 or 2-5, femora distally below more or less, tibiae 

 below and on anterior border, tarsi in varying degree, yellow. 



The flagelliim is cylindrical; segments 7 and 8 are very faintly 

 spinose on posterior border, due to the presence of specialized areas, 

 wliich on these and on the more apical segments do not assume the 

 form of prominent pits. The apical segment is not curved, is rounded 

 at the apex and is somewhat shorter than the combined length of 

 the two just preceding it. The middle femora are finely serrate below. 

 The middle tarsus is relatively shorter than is usual for the species 

 of this genus, but on all specimens before me it is somewhat longer 

 than its subtending tibia. The second and sixth sternites are usually 

 without processes of any kind, but occasionally a very small one is 

 found on the sixth. The seventh bears a median carina and also a 

 pair of less prominent lateral carinae. 



Female. — Black: Labrum, clypeus, scape below, spot between 

 antennae, abbreviated anterior orbits, much reduced posterior orbits, 

 femora distally below more or less, tibiae on anterior borders, tarsi 

 in varying degree, yellow. Lateral spots on tergites 2-4 or 2-5, in 

 some specimens broad at the sides but attenuated toward the mid- 

 line, where they are more or less approximated, lateral spots on 

 sternites 2-4 or 2-5, yellowish or greenish white. 



Length. — 13-17 mm. 



The eyes in this species are widely separated, slightly more so in 

 the female than in the male, and their inner margins are ahnost par- 

 allel. The head, thorax, and base of abdomen are covered with rather 

 long white pubescence; elsewhere on the abdomen the pubescence is 

 shorter. The ultimate tergite of the female is evenly and coarsely 

 punctate, giving its surface a roughened appearance; laterally it is 

 provided with long white pubescence among which are placed some 

 short black spines. The extent and the intensity of the black marks 

 upon the tarsi vary much, but on both sexes the hind tarsi are 

 constantly very dark, almost black above. In his description of 

 this species Handlirsch fails to state the color of the maculations. 



The male of this species is distinguished by the presence of the 

 black borders on the clypeus, which leave the central yellow spot in 

 the form of a triangle with the apex at the midline of the base of the 

 clypeus. It is further distinguished from the following species by 

 its smaller size and by the presence of the black color of the tibiae, 

 a mark that also distinguishes the female of this species froju that of 

 the following. 



HaUtat.— Georgia., Florida, Texas, and New Jersey. 



Nmnber of specimens examined — Males, 13; females, 5.
