smaller and sparser in front. Elytra distinctly wider than 

 prothorax; each with four feeble discal costae or remnants of 

 same; densely and rather finely granulate-punctate. Length 

 (cJ, 9), 8-11 mm. 



9 • Differs in being somewhat wider, appendages 

 slightly shorter, and tip of abdomen rounded instead of 

 slightly notched. 



Hab.—Lord Howe Island (A. M. Lea). Type, I. 6585. 



In general appearance close to the preceding species, and 

 belonging to the same section of the genus, but elytral suture 

 not pale, the head maculate, the metasternum dark, and the 

 palpi normal. Puncta (also with a maculate head) is a more 

 polished species, with coarser punctures, elytral suture con- 

 spicuously pale, prothoracic spots differently placed, and with 

 many other differences. The prothoracic spots are much as 

 on some specimens of Oxacis australis, but the mandibles are 

 bifid. In some respects it is close to G. litoralis, but the head 

 has an isolated spot, the labrum is pale, the prothoracic 

 spots are different, and the basal joints of the antennae are 

 not longitudinally divided in colour. The flavous parts are 

 the head (except for a rounded interocular spot), prothorax 

 (except for a fairly large rounded spot on each side in front, 

 and the prosternum in front of the front coxae), and the legs 

 (except for the knees and parts of the tibiae and tarsi, these 

 being more or less deeply infuscated) ; from two to five of the 

 apical joints of antennae are more or less conspicuously 

 diluted with red; the elytra have a vague bluish or greenish 

 gloss; the abdomen of the male is transversely red at the 

 tip, of the female longitudinally red. 



COPIDITA OBLONG1COLLIS, n. sp. 



<S . Reddish-flavous ; elytra dark metallic-blue; head 

 with a wide median space, a spot on each side near front 

 of prothorax, mesosternum, metasternum, abdomen (tip 

 excepted), tips of mandibles and part of apical joint of palpi 

 black or infuscated. Clothed with short, depressed, white 

 pubescence, more noticeable on the suture and elevated lines 

 on elytra than elsewhere. 



Head long, flat between eyes and gently concave in front; 

 with dense but rather small and not very sharply-defined 

 punctures; mandibles bifid. Eyes rather large, but scarcely 

 interrupting the general obliquity of the sides. Antennae 

 moderately long and rather thin, eleventh joint slightly 

 longer than tenth, and feebly semi-double. Prothorax dis- 

 tinctly longer than wide, sides feebly dilated to near apex, 

 apex and base each distinctly incurved to middle, base lightly 

 upcurved, with a shallow median line, and a very vague
