This species and the foliowiug belong to G-roup VII, on account 

 of the 10-jointed antennae ; they are more globose and smaller than 

 C. hironh and C. saraivaJcensis. Unfortunately both are unique. 



Cyathiger raffrayi sp. n. (Plate XX, fig. 8, J .) 



(J. Sub-globose, attenuate in front, convex, rufo-castaneous, finely and 

 confluontly punctured, leather nitid, with very short pubescence. Head a little 

 longer than broad, sides behind eyes rounded to base, attenuate in front; 

 frontal tubercule rounded, shortly sulcate; eyes large, situate at about middle. 

 Antennae with ten joints : 1 large, 2 transverse, 3, 4, 5 transverse and compact, 

 6, 7, 8 transverse, each gradually broader, 9 narrower, 10 large, transverse, with 

 ninth inserted near the outer margin, the apical and basal margins meeting in 

 a point within. Maxillary palpi with last joint large, almost oblong, rounded 

 at apex. Prothorax a little broader than long, with sides rounded, attenuate 

 in front. Elytra large, about as broad as long, slightly attenuate and rounded 

 at base, with two basal foveae. Abdomen half as long as elytra, attenuate to 

 apex. Femoi-a stout, tibiae incrassate from about middle to apex. Length, 1 mm.

Belongs to G-roup VII. Allied to C. hidhifer, but differs in the 

 shape of the head, the less globose form, the larger eyes, and the more 

 attenuate abdomen. I have much pleasure in dedicating this species 

 to Mons. A. Raffra}^ to whom we are indebted for so much fine work 

 on the Pselaphidae. 



Cyathiger malayanus sp. n. (Plate XX, fig. 9, ^ .) 



(? . Sub-ovate, attenuate in front, convex, ferruginous, very finely and 

 confluently punctured, with rather dense pubescence. Head a little broader 

 than long, attenuate in front and truncate, with sides behind eyes rounded to 

 base ; eyes placed at about middle, rather prominent. Prothorax a little 

 broader than long, slightly longer than head, widest a little before middle, 

 with sides rounded, and mesially sinviate ; a small fovea in centre near base. 

 Elytra twice as wide as prothorax, and nearly twice as long, rounded at 

 shoulders, three basal foveae present ; depressed at sviture, and shortly silicate. 

 Abdomen shorter than elytra, with sides roiinded to apex, feebly margined near 

 base. Metasternum transverse and concave in middle, with a blunt tooth on 

 each side projecting over the coxae. Ventral surface of abdomen entirely 

 excavate in middle with the margins of excavation rugosely carinate. Femora 

 stout. Tibiae incrassate from middle to apex. Antennae with ten joints, 

 about as long as head and prothorax combined : 1 quadrate, 2 transverse, 

 3, 4, 5 transverse and very compact, ./ - 9 transverse, each about equal to 2, 

 10 large, strongly transverse, with the ninth joint inserted near outer margin, 

 acuminate within. Maxillary palpi with last joint short, oval. Length, 1.30 mm.
