3. LARRADA ?DILIS. L. nigra; facie argenteo-pilosa, alis subhyalinis, articulis apicalibus tarsorum rufo-testaceis, abdomine l?vi et nitido.
Female. Length 5-1/2 lines. Black; head and thorax subopake, the abdomen shining; the face densely covered with silvery pile, the cheeks, sides of the thorax and abdomen thinly so; the tips of the mandibles and apical joints of the tarsi ferruginous, the latter obscurely so. The metathorax transversely and rather finely rugose, the truncation more strongly striated; the scutellum shining; the wings subhyaline, the nervures ferruginous; the tibi? with scattered spines, the tarsi spinose.
4. LARRADA AURIFRONS. L. nigra; facie mesothoracis metathoracisque lateribus aurato pubescentibus, abdominis marginibus segmentorum trium basalium argentato piloso fasciatis; alis fuscis.
Male. Length 8 lines. Black; the face and outer orbits of the eyes clothed with golden pile; the lateral margins of the mesothorax and the metathorax thinly clothed with golden pile; wings dark fuscous with a violet iridescence; the three basal segments of the abdomen with fasci? of silvery pile.
Hab. Celebes.
5. LARRADA PERSONATA. L. capite thoraceque nigris, abdomine ferrugineo.
Female. Length 8-1/2 lines. Head, thorax, and legs black; the two former closely punctured and thinly covered with short cinereous pubescence; the metathorax with the punctures running into transverse stri? in the middle; the sides of the thorax and the legs with a fine silky silvery-white pile; the tibi? and tarsi strongly spinose; wings fusco-hyaline; abdomen entirely red, smooth and shining.
The male is smaller, and has the four apical segments of the abdomen black, the face, cheeks, and apical margins of the segments of the abdomen with silvery pile.
Hab. Celebes.
This is probably merely a variety of L. simillima, wanting the black apex to the abdomen; it very much resembles the L. anathema of Europe.
6. LARRADA RUFIPES. L. nigra, mandibulis pedibusque rufis; alis hyalinis, venis pallide testaceis; abdomine sericeo-piloso.
Female. Length 7 lines. Black; the head smooth and shining; the clypeus, the cheeks, and face anteriorly covered with silvery pile; the scape in front, the mandibles, and palpi ferruginous. Thorax: the sides and beneath with a thin silvery-white pile; the legs ferruginous with the cox? black, the posterior pair red beneath; the thorax closely punctured, the metathorax transversely striated; wings fulvo-hyaline, the nervures pale-testaceous. Abdomen shining, very closely and delicately punctured; thinly covered with a fine white silky pile, which is very bright on the margins of the segments, which are slightly rufo-piceous.
The male closely resembles the female, and is similarly sculptured and coloured.

7. LARRADA FESTINANS. L. nigra; facie abdominisque marginibus segmentorum argentato-pilosis.
