CYLINDRORHINIDAE. 67 



coxae separated by the narrow cuneiform mesosternal process, the posterior 

 widely separated. Mctasternum short. Basal ventral segment in the middle 

 evidently longer than the next one. or the metasternum, its hind suture 

 a little sinuate ; the 3rd and 4th together quite the length of the 2nd, with 

 deep sutures ; 5th as long as 2nd, truncate behind ; 6th short but distinct. 

 Epipleurae narrow. Buccal cavity closed. Palpi invisible. 



Phaeophanus, Anagotus, and Heteraomus possess ocular lobes, and 

 therefore form a distinct section. In Sargon the posterior corbels have 

 double ciliae and a narrow external truncature, the eyes are subrotundate, 

 and the scape attains the back of the eye. In Pparchus the scrobes are 

 oblique and short, iind the penultimate tarsal joint is deeply bilobed. In 

 PJwxotcles the palpi are fully exposed, the scrobes are short and directed 

 to the lower surface, the eyes are placed near the thoracic margin, the bare 

 clypeal portion of the rostrum is not perceptibly marked off, and, moreover, 

 there are only 5 abdominal segments. 



It has therefore been deemed expedient to establish this genus Phaedro- 

 pholus for the systematic location of the only exponent at present known. 

 Phoxoteles, in appearance, most nearly resembles it. 



3135. Phaedropholus o'connori sp. nov. 



Derm dull fusco-niger, most discernible behind the eyes, and as a some- 

 what cruciform mark between the antennae ; the mandibles, apex of 

 rostrum, and numerous minute granules on the thorax and elytra are shining 

 t)lack ; the squamosity is dense, minute, and depressed, mostly fusco- 

 ferruginous, on some parts slightly metallic, towards the posterior declivity 

 and sides of the elytra the squamae become much paler, across the elytra 

 there are 2 slightly infuscate much interrupted fasciae, and at each side of 

 the declivity a darker space ; pallid scales form on the thorax a streak along 

 the middle and one at each side, cover the scutellum, and border the inner 

 side of the eyes ; legs and tarsi similarly squamose and setigerous, the 

 femora with a pale band. 



RostruiH with a shght median carina, the apex and mandibles bear some 

 elongate fulvescent setae ; there is a narrow interocular impression. Thyrax 

 slightly dilated laterally before the middle ; with a median ridge in front, 

 and behind this a broad impression, which has obtusely raised borders 

 towards its frontal portion ; near each side, in front, a large flattened space 

 is limited behind by a curvate ridge ; these raised parts, and the sides, 

 bear subdepressed setae ; there is no visible punctation ; the granules 

 behind the middle are rather coarser and more numerous than elsewhere. 

 Elytra slightly broader than thorax at the base, subtruncate there, not 

 twice as broad at the middle, with slightly nodiform apices ; on each elytron 

 there are 6 discoidal series of comparatively small distant punctures, the 

 outer series a little coarser, the 3rd and 4th end at the declivity, the sutural 

 2 become indistinct but substriate towards the apex ; the 3rd interstices are 

 only moderately and somewhat unevenly elevated, and a little nodiform 

 behind the posterior femora and half-way down the declivity ; the 5th are 

 nearly similar, but terminate at the dark subapical area, the suture is a little 

 elevated behind ; the sides of the dorsum are uneven, irregularly nodiform, 

 and setose ; on the basal portion, but not outside the 5th interstices, there 

 are series of minute granules. 



Underside shining, nigrescent ; metaslcrnum and basal 2 segments densely 

 minutely squamose and setigerous, with granular sculpture ; segments 3 

 to 5 with ferruginous setae, scanty on the middle, thick at the sides ;
