Transvaal: Moorddrift (Swierstra, Oct. 1909) (allotype); Magalies- kraal, 60 km. NW. of Pretoria (Lingnau, 27 Jan. 1926). Holotype without locality-label, but without doubt also from the Transvaal. Lomatia semiclara n. sp. A unique ^-specimen in the collections resembles both chraecoptera and hemichroa very closely as regards its wing-infuscation. Compared with these two species it however differs in the following respects: Wings with the yellowish brownish infusion almost identical, also occupying more or less basal two-thirds, but agreeing more with that of hemichroa in being more extensive and also present in third and fourth posterior cells and also in anal and axillary cells, the latter two cells especially not so clear as in chraecoptera; apical margin of infusion however slightly darker, sub-band-like as in latter species; clear apical part of wings slightly more greyish hyaline, not so vitreous hyaline as in the other two species; basal comb also rudimentary; base of second submarginal cell acute as in chraecoptera; middle cross vein at about between apical third and apical fourth of discoidal cell; the latter acute apically as in chraecoptera, its apical vein also slightly sinuous. Vestiture on body above more dis- tinctly yellowish than in 0*6* of the other two species; sides of abdomen and hind margin of last tergite without any dark or black intermixed hairs; hair on pleurae and venter less contrastingly whitish. Head with the inter- ocular space in £ in front of ocellar tubercle much broader than in chraecoptera and even slightly broader than in hemichroa; proboscis fairly long, about 2 mm. long, its labellar lobes remarkably long, longer than antennal joint 3, much longer than in other two species and both these and base of proboscis with distinct spinules below.
