Trypoxylon tainanense STRAND çf Ç : 16 = çf, in terantennal enclosure, 17= çf, clypeus, 18 = çf, apical part of antenna, 19 = çf, basal part of abdomen, 20 = çf, genitalia seen from beneath, 21 = çf, dissected left half of genitalia seen from inside (P, penis valve), 22 = 9 > interantennal enclosure, 23 = 9 > clypeus, 24 = 9 > basal part of abdomen. both strongly and coarsely striate, sides transversely, somewhat arcuately, fairly closely striate, with intervals finely punctulate, sculpture anteriorly weaker. Remarks. In the examined female specimen the frontal shield with the lower carinae weaker upwards and almost obliterated for some distance before the lateral angles, while the upper carinae wholly distinct, even just above the lateral angles (inverse is the case in a female at my hand). 39.

The two specimens below listed are so much deviated from the normal ones in colouration that at first sight it is likely to be taken as a different species. In both the specimens the abdomen is almost wholly black, leaving the reddish part only vestigially towards middle: In the specimen from Kanshirei there is no reddish part on the dorsal side, only the underside from apex of segment 1 to base of segment 4 pale brown. In this specimen tbe rest of the abdomen and the legs are wholly castaneous brown, but this may be due to colour fading. In the specimen from the Island Lambeh apices of abdominal segments 1 and 2 and bases of 2 and 3 very narrowly ferruginous and the ferruginous areas slightly broadened ventrally. In the morphological distinctions the specimens well agree with the normal ones as given in Figs. 25 (clypeus), 26 (antenna), 27 (lateral pronotal process in front of procoxa), 28 (8th sternite) and 29 (genitalia, ventral view). The specimens: 1 çf, Kanshirei, 1908; 1 çf, Isl. Lambeh, I. 1908.
