54:6 Dr. G. A. K. Marshall on new 



Subfamily Rhytiebsininm, 



Genus Philet^robius, nov. \ 



Body much flattened dorso-ventrally. Head continuous 

 with the rostrum^ strongly exserted, the distance between 

 the hind margin of the eye and the prothorax being equal to 

 the length of the eye ; the eyes quite flat, of irregular shape, 

 and entirely concealed from above. Rostrum very stout, 

 deflexed, narrower than the head at the base, but gradually 

 dilated in front, the depth equal to the basal width, the sides 

 almost vertical ; the scrobes very deep, sharply defined, 

 curving downwards in front of the eye and uniting shallowly 

 beneath; the scaling evenly continuous right up to the 

 apical margin, which is broadly truncate ; the buccal aperture 

 very oblique, the mandibles not projecting, bidentate, and 

 squamose at the base ; the submentum hardly pedunculate, 

 the mentum rather large, but leaving the maxillary palpi 

 exposed at the sides and bearing two discal setse. Antennoi 

 squamose; the scape sliort, gently curved, and just reaching 

 the front margin of the eye; the funicle 7-jointed; the 

 club ovate, about as long as the 3| preceding joints, and 

 without definite annulations. Prothorax vertically truncate 

 in front, without any trace of a prosternal furrow; the 

 transverse prosternal stria deep and placed about halfway 

 between the coxse and the front margin. Scutellum invisible. 

 Elytra much flattened, strongly inflexed at the sides so as to 

 embrace the abdomen, much broader than the prothorax, 

 obliquely rounded at the shoulders, with 10 stiise. Legs 

 with the front coxse contiguous, the middle pair rather and 

 the hind pair very widely separated ; the trochanters without 

 a seta ; the femora gradually and not very strongly clavate, 

 simple, the hind pair reaching only the apex of the 3rd 

 visible ventrite ; the tibiae shortly mucronate at the apex, 

 with the dorsal edge somewhat flattened and deeply sinuate 

 in the hind pair, more shallowly so in the anterior pairs, the 

 apical margin armed with 6-8 stout spines in front of the 

 tarsus and 2-3 behind it ; the tarsi short and rather stout, 

 not spongy beneath, but squamose and setose, joint 2 trans- 

 verse, joint 3 a little longer and bilobate, but scarcely 

 broader ; the hinder claw reduced to a minute tooth at the 

 base of the other. Sternum witli the mesosternal process 

 rather prominent, the mesepisterna reaching the elytra and 

 the mesepiraera very small; the metasternura much longer 

 than the middle coxge, its episterna broad, but the suture 

 visible only as a mere rudiment at the base; the hind coxae 

 separated from the elytra by a little more than their own
