CAMERON—HYMENOPTERA. ffi! 
6. Meguachile seychellensis, sp. nov. 
Black; the pubescence, including the scopa, white; the wings hyaline, iridescent, 
slightly tinged with violaceous, the nervures black. Front, vertex, thorax, and abdomen 
closely, distinctly, somewhat strongly punctured; the puncturation on the face and 
clypeus is stronger, but not so close; there is a smooth space in the middle of the face 
and in the middle of the upper half of the clypeus. The outer side of the mandibles 
closely rugosely punctured; the inner part with scattered elongated punctures on the 
basal half, the two divisions being separated by two keels of which the outer is the more 
distinct ; the apex ends in two broad, distinct teeth, the apical being slightly the larger ; 
the basal inner edge is broadly roundly curved. The base of metatarsus is not much 
more than half the width of the apex of the tibize. Head wider than the thorax. Apex 
of clypeus smooth, shining; its centre slightly arched inwardly, not transverse or 
rounded outwardly ; it is about one-fourth wider than long. Tegulse black on the inner, 
lead-coloured on the outer side. ‘The hair on the head and pleure is long and dense. 
The outer edge of the apex of the hind tibiz is roundly incised. Metanotal area clearly 
defined, aciculated, depressed in the middle. 
The male has the incision in the centre of apical segment large, wider at the apex than 
it is long in the middle; the middle at the base sharp; not broadly rounded; the 
lateral apical angles triangular. Flagellum of antenne piceous below. Fore coxze with 
a short triangular tooth on the inner side. The male appears to have the apical half of 
the wings much more deeply violaceous than the female; the wings in the latter vary, 
some having the violet tint more distinct than others. 
The hair on the underside of the hinder metatarsus may be tinged with rufous, as 
may also the scopa. 
Length 9-10; breadth 3-4 mm.
