RHYPAROSOMIDAE. 553 



base and apex, without ocular lobes, only slightly longer than broad, a little 

 dilated at the middle, irregularly and, relatively, moderately coarsely 

 punctured. Elytra oviform, doable the length of thorax, much more convex, 

 strongly arched above and behind, scarcely perceptibly broader than it is 

 at the base and closely adapted thereto ; each elytron with four dorsal, 

 deep, distinctly punctured striae extending from base to apex ; interstices 

 convex, the one near the suture depressed and narrowed and not reaching 

 the basal margin. 



Basal ventral segment largest; cuneate between the coxae, slightly 

 depressed and sparingly punctate in the middle, and on a higher level than 

 the second, which is not twice the length of the third or fourth, fifth with 

 short, depressed grey setae and a few punctures. Intermediate coxae 

 slightly separated, as large and prominent as the anterior. 



This differs as follows from R. altipennis (3907) : — 



Rostrum not sulcate. Eyes large, nearly flat, with coarse facets, almost 

 touching the thoracic margin, not widely separated above. Head not 

 crested. Scape only reaching the front of the eye Elytra distinctly 

 punctate-striate. Penultimate tarsal joint excavate in front, apparently 

 entire and finely setose underneath, fourth almost as thick, not longer than 

 preceding two together, the claws small and strongly bent downwards. 



Length (rostrum exclusive), 2 mm. ; breadth, 1 mm.

 4088. Clypeorhynchus dorsalis sp. nov. 



Elongate, rather narrow, slightly convex, subopaque, without crests, 

 nodosities, or outstanding setae ; thinly clothed with flavescent, decumbent 

 setae, those along the sides more squamiform and with a tendency to 

 concentrate in irregular patches on the hinder part of the elytra ; fuscous, 

 antennae and tibiae usually castaneo -rufous. 



Rostrum a .third shorter than thorax, rather coarsely and closely 

 punctured and indistinctly tricarinate behind the antennae, slightly dilated, 

 finely punctate, nitid and rufo-piceous in front. Thorax very little longer 

 than broad, slightly wider before the middle than elsewhere, more gradually 

 narrowed towards the truncate base than in front ; disc moderately closely 

 and coarsely punctured, the shallow impression along the middle somewhat 

 deeper near the apex. Scutellum small. Elytra elongate, double the length 

 of thorax, hardly a fourth broader before the middle, scarcely any wider 

 at the base, with feebly narrowed shoulders, from thence very gently 

 narrowed towards the hind slope, with simple apices ; dorsum nearly plane, 

 the striae with suboblong rather shallow punctures ; interstices somewhat 

 uneven, the third shghtly elevated behind the middle, and, like those 

 outside them, bearing series of small, sometimes indistinct, granules. 



Scape flexuous, slender, gradually incrassate beyond the middle, with 

 a few erect setae, it reaches the thoracic apex. Basal joint of funiculus 

 evidently longer than the next, third and fourth rather longer than follow- 

 ing ones ; club elongate-oval. Tibiae distinctly dilated inwardly above the 

 middle. 



Male. — Underside nitid, rufo-piceous, finely setose, moderately closely 

 punctate. Presternum strongly incurved in front. Metasternum broadly 

 impressed behind. Basal ventral segment broadly depressed, longer than 

 second, the suture shghtly sinuate, third and fourth together as long as second,
