COLLECTED AT CELEBES. 77 



legs black ; the thorax roughly pimctui-ed, oblong-quadrate, with the 

 metathorax obliquely truncate ; the mandibles ferruginous in the 

 middle. Abdomen with two ovate spots towards the base, and an in- 

 terrupted band at the base of the third segment, of white pubescence ; 

 the apical segment longitudinally striated, and fringed at the sides 

 with glittering yellowish-white hairs. 



Male. Length 9 lines. The head and thorax coarsely punctured ; the 

 sides of the face anteriorly, and the base of the mandibles covered 

 with silvery-white pubescence; the wings dark brown and shining. 

 The first, base of the second, and the apical segment of the abdomen, 

 black ; the two former strongly punctured, beyond which it is finely 

 and distantly punctured ; the second and fom* following segments with 

 a fringe of bright fulvous pubescence on their apical margins. 



The female very closely resembles Mutilla Sibylla, but may be distin- 

 guished from it by its having the tubercles on which the antennae 

 are inserted black; in M. Sibylla they are ferruginous. The male 

 resembles the same sex of M. Sibylla, but in that insect the segments 

 of the abdomen are fringed with white pubescence.

Probably the female o( M. gracilis; but I do not feel justified in uniting 

 them.
