cellum half as long as first flagellar joint; first two joints of 
flagellum subequal; scutum subopaque with distinct, close pune 
tures; scutellum more shining, with slightly smaller and move 
widely separated punctures; at the base of the scutellum are two 
circular pits; mesepisternum shining, with well separated distinct 
punctures ; prepectus without sculpture; prepectal furrow crenu- 
late; dorsal aspect of propodeum coarsely reticulate ; the posterior 
aspect vertical, transversely wrinkled and with a narrow longi-

tergites shining; pygidium, closely punctured, acute apically, not 
twice as long as basal width; legs feebly spined; hind basitarsis 
one-third longer than the longer calcarium ; third abcissa of radius 
slightly shorter than the second which is distinctly shorter than 
the first; recurrents meeting on the cubitus; second abcissa of 
cubitus half as long as third. Black; apices of mandibles and the 
palpi piceous; face, sides of propodeum and apical margins of

Larra lugonensis, new species. 
Female.—Length, 12 mm. Anterior margin of the clypeus 
regularly rounded, without teeth, smooth; basal part of clypeus 
and lower inner orbits with small, rather close punctures; facial 
basin deeply depressed, walls rounded, shining, and with a median 
furrow; vertex shining with small, scattered punctures ; anterior 
ocellus in a broad U-shaped depression which is parted in the 
middle by a distinct furrow from the ocellus; behind the lateral 
ocelli is a transverse furrow which in the middle extends caudad 
as a U; distance between the eyes at the vertex half as great as 
at the clypeus; scape and pedicellum shining, the apical part of 
the scape as long as flagellar joints one plus two; pedicellum but 
little shorter than the first flagellar joint; flagellum sericeous, 
the first three joints subequal; mesoscutum opaque with distinct 
punctures which are separated by about twice their diameter ; 
scutellum shining, with well separated distinct punctures ; mese- 
pisternum opaque, sculptured like the scutum; prepectal furrow 
crenulate; sides of the propodeum shining, with well-separated 
setigerous punctures, basally becoming smaller and almost disap-
