578 Mr. P. Cameron on new 
apex, the sides bulging outwardly. Pleure closely punc- 
tured, the metapleurz more closely than the rest, the lower 
part of the propleure striated. 
May be known from S. rufipes, Cam., by all the femora 
being for the greater part black, by the marks on the meta- 
notum being straight and oblique on the top, instead of the 
inner three fourths being rounded and raised above the outer 
edge, the base of the tibiz pale, not bright red, and there is 
no yellow on the scape of the antennz, the flagellum, too, 
being darker coloured. 
Chiaglas longicornis, sp. 0. 
Black; the scape of the antennze below, jomts 9-16, and 
the base of the mandibles, white; the scape for the most 
part testaceous and thickly covered with fulvous pubescence ; 
the face, clypeus, the inner orbits to the end of the eyes, the 
lower half of the outer to the mandibles, the palpi, the edge 
of the pronotum, the scutellums, the sides of the apical slope 
of the median segment (including the spines), the tubercles, 
the centre of the lower part of the mesopleurs, their upper 
edge, the apex of the first segment narrowly, of the second 
and third more broadly, of the fourth to sixth more narrowly, 
and the seventh and eighth entirely, pale yellow. Legs 
rufous, the coxe and trochanters pallid yellow ; the hinder 
coxee black, with a broad, oblique, yellow band on the top, 
the hinder trochanters yellow, the apical third of the femora, 
the apex of the tibiz more narrowly, and the tarsi, black ;

Face and top of clypeus closely punctured and covered 
with short pale hair; the apex of the clypeus black. Meso- 
notum closely punctured all over and thickly covered with 
short fuscous pubescence, as is also the scutellum, which is 
sparsely punctured. Median segment closely punctured and 
thickly covered with pale pubescence ; the punctures on the 
sides run into reticulations ; the areola is longer than broad, 
not much narrowed towards the apex, its base rounded ; it is 
rugose, its base, apex, and, to a less extent, the sides are 
irregularly striated ; the posterior median area transversely 
closely striated. Pleurz closely but not strongly punctured, 
the mesopleure with a plumbeous hue, the base finely, the 
lower half of the apex more strongly, striated; the meta- 
pleure more closely and strongly punctured, the centre 
closely striated. Postpetiole closely, minutely, longitudinally 
striated. Gastroceeli closely striated.
