CUDNELLIA APICALIS, n. Sp. 



PL viii., figs. 153-155. 

 S > Black, with a coppery gloss ; labrum and appendages 

 reddish, but tips of several joints of antennae blackish. Upper- 

 surface glabrous, under-surface and legs very feebly pubescent. 



Head with fairly dense but not crowded punctures of 

 moderate or small size, becoming much smaller on clypeus, not 

 depressed between eyes, but with a feeble longitudinal impres- 

 sion towards base. Eyes rather small, prominent, and entire. 

 Antennae elongate, first joint rather stout, second not much 

 shorter than third, eleventh somewhat stouter and longer than 

 tenth. Prothorax about twice as wide as the median length, 

 sides strongly rounded, front angles greatly below middle ; with 

 numerous small punctures interspersed with much smaller ones. 

 Elytra scarcely longer than the greatest width, which is before 

 the middle, base truncate and the width of base of prothorax ; 

 with rather small punctures, in places in double or semi-double 

 rows, and rather dense and irregular on sides, where (behind 

 the shoulders) they are somewhat larger than elsewhere. Flanks 

 of prosternum with scattered punctures and many fine wrinkles. 

 Abdomen shallowly depressed at apex. Legs stout and rather 

 long; femora edentate; tibiae with acute costae, acutely 

 triangularly armed at outer apex ; basal joint of four front 

 tarsi strongly inflated. Length, 3|-4 mm. 



9 • Differs in having the abdomen more convex, apical 

 segment simple, in the tarsi, and in the sides of the elytra.

Considerably larger and more robust than mi/sfica, and 

 the elytra very different towards sides, but in all features 

 agreeing with the original generic diagnosis ; the tibiae, how- 

 ever, are much more produced at the apex than on mystica, 

 much, in fact, as on Edusoides pulcher. Specimens were sent 

 some years ago to the late Rev. T. Blackburn, and although 

 not described by him they were standing in his collection as 

 belonging to Cudnellia. The elytra (except at the margins) 

 are entirely without true striae ; those of the female differ 

 considerably from those of the male, as towards each side they 

 have three (four posteriorly) undulated ridges, on some speci- 

 mens appearing as irregular series of elongated tubercles. The 

 front tibiae at the apex are concave on the lower-surface for 

 the reception of the base of the tarsi ; seen from below a small 

 subapical tooth (suggestive of several species of Agetinus) 

 may be seen, in addition to the strong apical armature.
