558 Mr. Cameronjggnotes on Hymenoptera, 
any depressions. Antenne arising from tubercles, and 
in front of them is a transverse suture. Mesothorax 
depressed and compressed at the sides. In front of the 
scutellum there is a deep transverse suture, from which 
runs on each side a deep suture to the prothorax, and 
a less conspicuous one in the middle, the space bounded 
by these sutures is deeply and coarsely punctured ; the 
space on either side bounded by them and the scutellum 
is shining and almost impunctate, except at the edges. 
Seutellum shining and impunctate m the centre; the 
rest and metanotum punctured. Spines on metanotum 
well developed. Abdomen longer and broader than the 
thorax, subovate, striated at the base, and with a long 
distinct central carina, and a shorter less developed one 
on either side; the rest smooth, shining, covered at the 
sides and apex with long scattered white hairs. Head 
and thorax densely pilose. Wings rudimentary, scarcely 
reaching beyond the petiole. Length 1} ln. 
Allied to M. cursitans, Nees, but easily known from it 
by the shorter and broader thorax, which is not uniformly 
punctured all over; more ovate abdomen, less elongated 
prothorax, and more pilose body.

Megaspilus mullensis, n. s. 
Black, shining, almost glabrous; scape, prothorax, 
base of abdomen and legs, with cox, testaceous. An- 
tenn longer than the body, filiform, glabrous ; scape a 
little longer than the head; third joint a little longer 
than the fourth; the rest subequal; last joint broken 
off. Head more than a half wider than the thorax, 
smooth, shining, impunctate; eyes almost glabrous. 
Thorax less shining than the head, slightly aciculated ; 
longer and somewhat narrower than the abdomen, which 
has the second segment striolated, but very indistinctly. 
Wings abbreviated, reaching to apex of second abdo- 
minal segment. Male. Length a little more than $ lin. 
Similar in coloration to M. thoracicus, Nees, but 
differing in its pile-less body, much broader head, 
thorax longer than abdomen, &e. 
Taken on a grassy slope on Ben More, Mull, at an
