tibiae, and tarsi of first pair of legs; spot at end of femur of second 

 and third pairs of legs; fole or soiled yellow. Aside from these 

 few maculations the body of the insect is a uniform smoky black in 

 color. The tarsi are not so black as the body proper. 



The inner eye-margins are parallel. The flagellum of one antenna 

 and the last three segments of the other are missing. Segments 7-9 

 of the remaining imperfect antenna are spinulose. The middle 

 femur is dentate. The second sternite bears a small, compressed, 

 pointed process, and sternite 6, a prominent, low, broad process 

 whose posterior, free border approaches a semicircle in outline; 

 there is also on sternite 6 a pair of small lateral processes on the ex- 

 treme posterior lateral angles of the sternite. The seventh tergite 

 is abruptly narrowed toward the apex, which is roundly truncate 

 (fig. 103). The wings are slightly infumated, the infumation being 

 heavier at the middle of the wing than at the apex. The second 

 abscissa of both the radiella and the cubitella is present. The 

 pubescence is short, dense, and gray in character. 



Length 15 mm. Described from a single male from Japan. 



Type. — In the Zoologisches Museum der Universitat, Berlin. 



BEMBIX OCULATA Latrcille 



Bembex oculata Latreille, Hist. Nat. Crust, and Ins.. vol. 13, 1805, p. 302. — 

 H.\NDLiRScn. Sitz. Akad. Wissensch. Wien. Marh.-Nat. CI., vol. 102. 1893, 

 p. 854.— Dalla Torre, Cat. Hym., vol. 8, 1897, p. 509. 



According to Handlirsch, this is a widely distributed and an ex- 

 ceedingly variable species and because of this great variation, du© 

 to the extent and the color of the maculations and to the presence 

 or absence of infumation in the wings, he recognized eight different 

 forms under which this species occurs. All the specimens before 

 me belong to what he termed the Southwest-European form. 



I have before me four males and five females, of which two 

 females and two males have been determined by Mercet. Of these 

 four the two males and the one female bear the label, " Madrid, 

 G. Mercet," and the second female, the label, " Los Molinos, G. 

 Mercet." Of the remainder one male and one female bear the label, 

 " J. Lichtenstein, Montpellier, France " ; one female bears the label, 

 "Sardinia, A. H. Krausse"; and the other male and female are 

 without locality labels.
