634 COLEOPTEK.V. 



Underside covered with depressed greyish scales, the bare spots irides- 

 cent. Metasternum and basal abdominal segment broadly depressed along 

 the middle, the next segment about half as long, fifth indistinctly foveate 

 behind. 



This corresponds with B. niticolUs as regards sex, structure of antennae, 

 and length of rostrum : the elytra, however, instead of being nearly 

 double the breadth of the thorax at the base, are only a little broader, 

 and the coloration, below as well as above, is dissimilar.

4210. Bryocatus rugosus sp. nov. 



Oblong, convex, minute, opaque, apparently glabrous; nigro-piceous, 

 tarsi and lunicle dull blauk. 



Rostrum as long as thorax, broad, arched, closely and relatively coarsely 

 but not deeply punctate. Thorax subquadrate, slightly constricted in 

 front, about a third broader than long ; closely, irregularly, and coarsely 

 punctate-rugose, with a moderate groove along the middle. Elytra just 

 twice the length of thorax, only slightly broader than it is at the base, 

 somewhat broader in line with the hind thighs, narrowed and subvertical 

 behind ; they are rather broadly striate, with the suture as well as the 

 second and fourth interstices more elevated than the others but rather 

 narrow, the surface more or less minutely asperate. 



Legs rather coarsely and closely sculptured, with a few dark setae. 



Scape short, subclavate ; basal joint of funiculus unusually large, about 

 half the whole length, joints 2-4 short and subequal ; club large, oblong- 

 oval. 



Underside subopaque, almost nude ; nigrescent, femora faintly iridescent ; 

 with rather coarse but ill-defined coriaceous sculpture. Metasteruum and 

 basal ventral segment broadly depressed along the middle. 



This minute, rugosely sculptured species may be easily separated from 

 other exponents of the genus by the deficient fifth and sixth joints of the 

 funiculus ; their absence, and the enlargement of the basal one, if similar 

 examples are brought to light, may render generic separation necessary.

4211. Phrynixus conspicuus sp. nov. 



Subovate. moderately elongate, opaque ; the derm castaneous and 

 slightly nitid, antennae, tarsi, ami apical half of rostrum fusco-rufous : 

 irregularly clothed with depressed tawny scales and setae, and with coarser, 

 erect,, woolly setae which form crests. 



Kiistruni rather longer than thorax, arched, nearly plane and slightly 

 broader before the antennae than behind, minutely tricristate on the middle. 

 more distinctly and longitudinally crested towards the eyes, which are flat. 

 Thorax oblong, a fourth longer than broad, its slightly uneven sides a little 

 narrowed anteriorly, base truncate ; disc nearly plane, broadly but not 

 deeply depressed at the middle of the base, moderately coarsely but not
