526 Mr. P. Cameron on 
From Myermo it may be known by the convex scutellum, by 
the hinder coxe having no tooth, the head is less strongly 
developed behind, and the gastrocceli are smaller and shallower. 
The nervure on the cubital discoidal nervure is distinct; the 
transverse basal nervure is not interstitial; the areolet is 
5-angled and narrowed at the top; the last ventral segment 
is nearly as long as the penultimate and is well developed all 
round; the areola on the metathorax is wider than long, is 
rugose and angled where the keels are received; all the arex 
are clearly separated and there is no lateral tooth. The 
occiput is transverse, in which respect it differs from Myermo ; 
the ocelli are placed well back, the hinder behind the eyes.

Antenne fulvous, distinctly tapering and darker towards 
the apex; the scape yellow, closely punctured. Face and 
clypeus strongly punctured, sparsely haired; the apex of the 
clypeus smooth, transverse, the sides rounded ; the labrum not 
visible. Mandibles and palpi yellow, the base of the man- 
dibles punctured; the apex black, indistinctly bidentate ; the 
lower part of the head next to the mandibles with a distinct 
leaf-like projecting border and clearly separated from and at 
a lower level than the lower outer orbits, which are margined ; 
the vertex punctured, the front transversely striated. ‘Thorax 
black ; the edge of the pronotum, the tegule, and scutellum 
yellow. Mesonotum closely and strongly punctured, thickly 
covered with short blackish hair; the parapsidal furrows not 
indicated, the middle lobe not defined. Scutellum roundly 
raised, shining, smooth, almost glabrous, the sides not carinate, 
the depression at its base of equal width throughout, narrow, 
smooth, and shining. Postscutellum closely shining, de- 
pressed at the base, the sides of the depression keeled. 
Median segment rugosely punctured ; the basal area as long 
as the posterior median, which is ae than long ; the sides 
at the base and apex slightly and obliquely narrowed ; the 
lateral basal aree are open on the outer side and are more 
strongly and more distinctly punctured than the middle; the 
apex of the segment is transversely rugosely punctured ; the 
keels bounding the posterior median area are indistinct; the
