Archive image from page 86 of Diptera from the Philippine Islands Diptera from the Philippine Islands dipterafromphili00oste Year: 1882 from the Philippine Islands. 231 The costa, the first and third veins in all these species are beset with bristles; only in T. Alkestis these bristles are very small on the costa and the third vein. In Macquart's figure of Acanthoneura their length must be exaggerated (D. E. II, 3, Tab. 30, f. 2). Themara hirtipes Rond. Ann. M. C. Gen. VII, 435 likewise seems to belong to the same group. Trypeta Manto n. sp. §. Although the only specimen which I have is very much damaged, I will attempt to describe it, on account of its singular venation. Yellowish-ferruginous; third antennal joint somewhat brownish; arista plumose; abdomen brown or black (damaged); halteres with a brown knob; legs uniformly yellowish-ferruginous. Wings brown; two triangular white spots on the costa, between the tips of the auxiliary and first veins; a small round white spot in the first posterior cell, not far from the anterior crossvein; a similar but less round spot at an equal distance from that crossvein, but on the opposite side, in the first basal cell; somewhat larger spots, one each side of the posterior cross- vein and a round one in the third posterior cell. This design has Fig. 11. a great resemblance to that of Themara ampla Wk., J. Pr. Lin. Soc. I, Tab. I, f. 5, but with this important diff'erence: in Trypeta Manto both triangular white spots on the costa lie within the stigmal cell (third costal cell of Loew. Monogr. etc. I, p. XXIVj; in T. ampla one of them is outside of that cell. The reason lies in the very peculiar venation of T. Manto: the stigmal cell here is unusually large, owing to the course of the first vein, the tip of which is more distal than in the related species; beyond this tip, the costa is stouter, as it is in T. Al- kestis, but for a shorter distance, and not so conspicuously; the second vein is much more deeply arcuated her
