144 SPOLIA ZEYLANICA. 
Mutilla ianthis, sp. nov. 
g. Ferruginea, abdomine nigro, secondo segmento maculis duabus 
albopilosis lateralibus, segmento tertio quartoque albopilosis in 
medio nigro-maculatis, area pygidiali longitudinaliter striata, 
thorace postice pectinato. 
Head and thorax strongly longitudinally rugose, pleura smooth 
and shining, abdomen closely and rather finely punctured, the 
pygidial area finely longitudinally striated. Eyes oval, situated 
a little nearer to the posterior margin of the head than to the base 
of the mandibles, the head rounded behind them, no broader than 
the thorax. Mandibles acute at the apex, with one very small blunt 
tooth on the inner margin. Scape shining and almost smooth, the 
second joint of the flagellum distinctly longer than the third. Tho- 
rax about one-third longer than the breadth on the posterior margin, 
slightly rounded anteriorly and a little broadened posteriorly, the 
sides crenulate and slightly concave, the posterior truncation 
vertical, shining, and almost smooth, the margin above the base of 
the truncation with ten strong teeth increasing in length towards 
the middle, the row of teeth continued by two or three very small 
ones on the sides of the truncation. No scutellar ridge. First 
abdominal segment much narrower than the second, which is 
broadest in the middle. 
Ferruginous, the abdomen black; a large round spot of white 
pubescence on each side of the second abdominal segment before 
the middle, the third and fourth segments covered with white 
pubescence with a large black spot on the middle of each. Flagel- 
lum and the apex of the mandibles black. 
Length, 7 mm. 
Hab.—Hambantota, Ceylon (fletcher) ; November. 
In some specimens the pile on the abdomen is golden instead of 
white. ‘ 
Somewhat allied to M. pectinospinata, Magr., but is a much smaller 
species. In the serration of the posterior margin of the thorax it 
approaches the group of serratula, Cam., but the markings on the 
abdomen are very different.

secundo maculis duabus lateralibus albopilosis, segmentis tertio 
quartoque apice albopilosis, thorace postice pectinato. 
Head and thorax coarsely rugose, abdomen finely punctured, 
pygidial area elongate ovate, very finely longitudinally striated, 
pleura concave, smooth. Eyes oval, situated nearer to the pos- 
terior margin of the head than to the base of the mandibles, the head 
rounded behind them, the scape shining and finely punctured, the 
second joint of the flagellum distinctly longer than the third. 
Thorax as wide as the head, very feebly rounded on the anterior 
s
