BEMBIX CONNEXA Fox. 



Bembex connexus Fox, Proc. Acad. Nat. Sci. Phila., 1895, p. 360, female, male. 



Female. — Black: Labrum, mandibles except apices, clypeus, scape, 

 and more or less of the flagellum below, lower part of frons, spot before 

 anterior ocellus, broad anterior orbits, posterior orbits broad below, 

 sides of prothorax almost entirely, frequently more or less complete 

 narrow line on posterior border of pronotum, lateral lines on scutum 

 usually abbreviated and sometimes wanting, sometimes small lateral 

 spots on scutellum, more or less of the side of the median segment, 

 spot on metapleurae, spot on mesopleurae, broad fasciae on tergites, 

 first interrupted and attenuated toward mid-dorsal line, second inclos- 

 ing pair of elliptical transverse dorsal spots or bearing a pair of 

 anterior dorsal emarginations and notched at midline on both mar- 

 gins, third similar to the second, fourth, and fifth each bearing a 

 pair of anterior dorsal emarginations and interrupted medially or 

 continuous, apex of ultimate tergite, lateral spots on sternites 2-5 

 and sometimes 6, median posterior spot on sternites 2-5 in some 

 specimens, on 2-4 in others, and entirely lacking in still others, 

 apical lines connecting the ventral spots on some specimens, spots 

 on anterior and middle coxae, greater part of femora, tibiae, and 

 tarsi, yellow. 



The pubescence is white, tolerably dense, longest on the head, 

 somewhat shorter on the thorax and base of abdomen. The thorax 

 is closely and evenly punctated; the punctations of the ultimate 

 tergite are coarser than that of the thorax and the sides of the segment 

 are provided with long white pubescence amid which are found 

 several short black spines. 



The male is smaller. There is a broad yellow line on the posterior 

 border of the pronotum and the sides of the prothorax are almost 

 wholly yellow. There are conspicuous lateral lines on the scutum, 

 lateral spots on the scutellum, fascia on metanotum, lateral spots 

 on dorsum and spots on the posterior surface of the median segment, 

 its lateral angles and sides broadly, and sides of mesopleurae and 

 metapleurae almost entirely yellow. The fasciae on the tergites are 

 broad and, except the first, continuous. The second incloses a small 

 pair of black spots; 3-5 are biemarginate on anterior dorsal margin, 

 and the seventh is maculated apically. There are lateral spots on 

 the sternites but none are connected by apical lines. In other 

 respects the maculations are similar to those of the female. Segments 

 6-8 of the flagellum are spinose on the posterior surface. The middle 

 femora are serrate. The second sternite bears a well developed 

 process and the sixth a smaller one. 



Length. — 16-20 mm. 



This species is large and robust, conspicuous for its intense black 

 color and bright greenish yellow markings. Not a great deal of
