dentate ; to a certain extent they cause the femora to appear 

 to be feebly grooved. The third tarsal joint is longer than 

 wide, and less deeply bilobed than usual ; but, as it is slightly 

 wider than the second, the tarsi cannot be regarded as linear. 

 The type appears to be a male. 



POROPTERUS CRASSIPES, U. Sp. 



Densely clothed (but in places almost or quite glabrous) 

 with sooty scales, variegated with more or less concealed 

 whitish ones. 



Head with coarse but more or less concealed punctures. 

 Eyes small and coarsely faceted. Rostrum stout and rather 

 short, sides incurved to middle ; with rows of large irregular 

 punctures, becoming much smaller, denser, and not seriate in 

 arrangement in front. Antennse inserted about two-fifths from 

 apex of rostrum ; scape unusually short and stout ; first joint 

 of funicle stouter and a trifle longer than second. Prothorax 

 almost as long as wide, lightly convex, sides strongly rounded 

 and strongly narrowed to apex, which is produced ; with a very 

 obtuse median carina ; with four feeble longitudinal fascicu- 

 late crests ; with numerous large punctures. Scutellum absent. 

 Elytra rather long, base scarcely wider than base of prothorax, 

 then gently rounded and near apex arcuate; with rows of 

 large punctures, becoming smaller (but still large) posteriorly ; 

 third and fifth interstices fasciculate near base, and at summit 

 of posterior declivity, many small fascicles elsewhere. Meso- 

 8ternal receptacle much as in two preceding species. Abdomen 

 with deep sutures ; first segment almost as long as three follow- 

 ing combined, near base with a strong curved impression and 

 deeply impressed in middle of apex ; second about as long as 

 third and fourth combined, with two notches just behind apical 

 fovea of the first ; two basal segments with large punctures, 

 the others with dense and much smaller ones. Legs, short ; 

 femora unusually stout, conspicuously grooved, hind pair 

 scarcely extending to apical segment; tarsi with third joint 

 not much wider than second. Length, 5 mm. 



Hah. — Victorian Alps (H. J. Carter). 



Close to ■sulciventris, but smaller and narrower, with some- 

 what different clothing and elytral punctures considerably 

 smaller and less angular, etc. The grooving of the femora 

 is an aberrant feature in the genus, but they are also grooved 

 in sidcivenfris, and the two species have the deep abdominal 

 sulcus of ruheter (a member of the exitiosus group). There is 

 a conspicuous but irregular line of whitish scales crowning the 

 posterior declivity, a few at the extreme base of elytra, two 

 or three together on each side of the middle of the prothorax, 

 similar spots close to each eye, and conspicuously variegating 

 the legs.
