smooth, bare, brown, and shining on the inner side ; on the outer 

 side it is thickly covered with pale, long, woolly yellow hair. 



Ammophila ateipes Smith. 



1'he female example is very large and has bright red legs ; the 

 males are not much more than half its size and have the legs 

 almost entirely black. Special locality not stated. 



Scelipheon javanum Lep. 



Singora. Several examples of this fine species. 



Sceliphkon madeaspatanum Fab. 

 Singora. One example. 



[Bembbx lactea, sp. n. 



Long. 22 mm. 



Hah. Khasia (coll. Rothney). 



This species wauts the U-shaped yellow mark on the mesonotum, 

 and comes into Bingham's Section B near to B. latitarsis (Fauna of 

 India, Hymenopt. p. 285). 



5 . Antennae black ; the scape of the antennse yellow, except the 

 apical half above, the 2nd joint, and the base of the 3rd beneath, 

 which are black. The yellow colour has a distinct pale olive tint ; 

 on the head, the clypeus, the labrum, the front, except for two large 

 oblique marks on the top continued from the black on the vertex, 

 the inner orbits to near the ocelli, the outer orbits more narrowly 

 from near the top, and the mandibles are yellow. The eyes slightly 

 diverge below ; the front and vertex are thickly covered with long 

 fuscous hair ; the front is broadly keeled ; on the top of the 

 clypeus are two oblique, large, iri'egular black marks. Mesonotum 

 black ; the scutellum black, except for a large transverse line in the 

 centre, which is dilated behind at the sides ; the base of the post- 

 scutellum is broadly yellow at the base. Median segment yellow, 

 except broadly in the middle at the base and two oblique lines — 

 broad at the base, becoming gradually nai'rowed towards the apex 

 — across the middle and one across the apex, black. The base of 

 the pronotum, an irregular mark on the propleurse behind, the 

 upper two-thirds of the mesopleurae at the base, the sutures 

 narrowly, and an irregular large mark on the apex of the meta- 

 pleurte, black. Legs of the yellow colour of the body ; the femora 

 and tibiae broadly lined with black — the former in front and behind, 

 the latter behind only. The ventral surface of the abdomen 

 entirely, the basal segment except for a large oblique line on either 

 side extendiug near to the middle of the segment and becoming 

 gradually narrowed from the outer to the inner side, black ; the 

 second and third segments are broadly black at the apex, the black 

 bands triangularly dilated in the middle at the apex ; near the 

 centre of these segments are two transverse black marks ; on the 

 base of the fourth segment is a large black mark, which projects 

 obliquely broadly at the apex and to a less extent on the inner
