Gyathiger ^nyrinecojjhilus s]).ii. (Plate XX, figs. 1, la, J; Ih, ? .) 



(J . Oval, slightly attenuate in front, convex, castaneous, finely and con- 

 fluently punctvired, with short, pale pubescence. Head broadei- than long, eyes 

 situate behind middle and rather prominent, head widest near base and slightly 

 rounded, narrower in front and nearly qiiadrate. Antennae equal in length to 

 head and prothorax combined, with seven joints : 1 large and obconical ; 2 and 3 

 shorter and transverse ; 4 — 6 slightly longer ; 7 large, transverse, with outer 

 margin slightly roiinded, thence acviniinate within, its upper surface convex, 

 covered with short, pale pubescence, beneath (see fig. la) concave, but not very 

 deeply excavate. Maxillary palpi with last joint slightly fusiform. Pro- 

 thorax a little longer than head and a little wider, almost gibbose, sub-quadrate, 

 rounded in front, sides sinuate about middle, with a small fovea in middle near 

 base. Elytra large, nearly equal in length to head and prothorax, nearly twice 

 as broad at their widest, shoiilders well marked, and sides rounded, with two 

 basal foveae. Abdomen shorter than elytra, attenuate and rovinded at apex, 

 punctuation slightly stronger than on the elytra. Metasternum concave. 

 Ventral surface of abdomen entirely excavate in middle, with margins feebly 

 carinate. Femora broad. Anterior and intermediate tibiae naiTower at base, 

 and incrassate from before middle to apex ; posterior tibiae incrassate to apex 

 after middle. Tarsi with three joints : 1 short, 2 and 3 mvich longer and about 

 equal, with single claw. Length, 1 .30 mm. 



$. Head smaller and eyes less prominent; last joint of antennae (see 

 fig. 16) a very little smaller, but the same shape as in ^ , the under surface not 

 concave, simply flattened, the upper surface convex ; and the ventral surface of 

 abdomen transversely excavate at base. Length, 1.30 mm. 



Hab. : Sarawak, Mt. Matang, alt. 2,000 feet (28.i.l4, found under 

 bark, witli ants). 



This species is evidently allied to C. sylvestris Eaffr., from New 

 Gruinea. It belongs to Group I, as the ^ has the apical joint of the 

 antennae strongly concave on the underside. 



Cyathiger inirandus sp. n. (Plate XX, figs. 2, 2a, ^ ; 26, ? .) 



(? . Oval, attenviate in front, convex, reddish-brown, strongly and con- 

 fluently punctured, with fine golden pubescence. Head a little longer than 

 broad, with sides rovinded behind eyes, frontal tvibercule prominent, almost 

 bilobed in front, shortly sulcate in centre ; eyes placed at about middle. Pro- 

 thorax a little longer than head, about as long as broad, widest just before 

 middle, attenuate and rounded in front, sides slightly oblique to base. Elytra 

 longer than prothorax, a little broader than long, sub-quadrate, widest just 

 before apex, slightly impressed at base near shoulders, the latter rounded. 

 Abdomen a little shorter than elytra, roimded and attenuate to apex. Meta- 

 sternum transverse and concave, with a blunt tooth at sides. Ventral surface
