the maculation on third, but reduced in extent ; posterior lateral spots 

 on fifth ; extreme posterior lateral edges of sixth ; legs, except black 

 stripe above on all femora, small black spot below on anterior tibiae 

 and one above on posterior tibiae, and a varying degree of black on 

 coxae and trochanters ; yellow. The fasciae on the tergites show two 

 colors, the posterior portion of each fascia being much lighter (more 

 nearly white) than the anterior portion. The first tergite, in addi- 

 tion to the broad dorsal fascia found on its curved surface, bears 

 a conspicuous fascia across its anterior vertical surface. The U- 

 shaped discal mark on the scutum shows a tinge of rufous. 



The flagellum above, except the terminal segment, is black; this 

 segment and the lower surface of the flagellum are ferruginous. 

 The clypeus and the lower part of the anterior orbits are covered 

 with a silvery pubescence. Elsewhere the pubescence is short and 

 white and presents the normal appearance. The frons between the 

 antennae and the base of the clypeus at midline are only slightly 

 carinate. The frons is broad and the inner eye-margins are slightly 

 wider apart at the vertex than at the clypeus. One anterior meta- 

 tarsus bears seven and the other eight spines, of which the two at the 

 apex of each differ greatly from one another in length. The disk 

 of the second sternite is shining and bears only coarse punctures. 

 The apex of the sixtlj tergite is broadly rounded and on the midline 

 is devoid of punctures. The sixth sternite is noncarinate and is 

 covered with coarse setigerous punctures that become smaller near 

 the basal lateral margin. The first intercubitus vein is almost 

 straight and the second abscissa of the cubitella is lacking. 



Length 13 mm. Described from a single specimen bearing the 

 label, " Pusa, Coll. Bingham." It also bears the laber, " Bembex 

 orientalis Hdl.," but by whom the determination was made is not 

 shown. 



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



BEMBIX BORNEANA Cameron 



Benribex horneana Cameron, Proc. Zool. Soc. Lond., vol. 2, 1901, p. 26. 



In the collection of the United States National Museum, bearing 

 the label, " Tambak," is a single female that has been identified as 

 Bemhix bornean^ Cameron, but by whom the identification was made 

 is unknown. Cameron based his description of this species on the 

 male alone, the female at that time apparently being unknown to 

 him. It is possible that this specimen was determined by Cameron 

 himself some time after his description of the species and sent to 

 Ashmead in an exchange, but of this we have no proof. If a de- 

 scription of the female of this species has been published, I have not 

 seen it.
