Ptolycus nodosus, sp. n. (PL XXX IX. fig. 6.) 



c?. Niger, subopacus, squcamuiis sparsis brunneis obsitus ; capite et rostro ad basin rude reticulato- 

 punctatis, hoc non carinato ; prothoraoe trausverso, lateribus valde rotuudato, latitudine 

 maxima in medio, supra vix punctate, apice excepto, ibi rude reticuiato, lateribus granulate ; 

 elytris ovatis, apice subtruncatis, parum profunde punctato-striatis, punctis distantibus,inter- 

 stitiis alternis tuberculis parvis umbilicatis seriatim obsitis, interstitiis aliis fere planis granulis 

 minutis uiiiseriatim instructis, squamis erectis nullis; pedibus squamis erectis obsitis, 

 femoribus rude puuctatis, tibise leviter carinatis. 



Colour black, with sparse minute recumbent light brown scales. 



Head coarsely and reticulately punctate throughout, except on the extreme vertex, 

 the forehead with a shallow transverse impression. Rostrum punctate like the head 

 in the basal half and without definite carinse or sulci. Antemm testaceous brown, the 

 four basal joints of the funicle elongate, 2 the longest and 4 the shortest, 5 slightly 

 longer than broad, 6 and 7 as broad as long. Prothorax evidently transverse, the 

 sides strongly rounded, broadest about the middle, much more narrowed in front than 

 behind, shallowly constricted near the apex, truncate at the base, the anterior dorsal 

 margin produced and rounded, the ocular lobes well developed ; the upper surface 

 impunctate on the disc, except for the minute scale-sockets, coarsely punctate on the 

 apical area, and sparsely granulate at the sides. Elytra ovate, the sides rather strongly 

 rounded, broadest a little before the middle, the apices jointly subtruncate, with very 

 shallow strise containing distant shallow punctures, the intervals almost plane, 1, 3, and 

 5 with a row of irregularly spaced tubercles, each of which has a central umbilicus 

 surrounded by a ring of scale-bearing punctures, the tubercles becoming much smaller 

 behind, intervals 2, 4, 6, and 8 each with a single irregular row of minute granules, 

 7 and 9 with a row of larger granules. Legs black, tarsi piceous brown, the femora 

 coarsely punctate, each puncture bearing a suberect scale-like white seta, the iihuM 

 bicarinate on each side and with narrower erect setae. 



Length 5^, width 3 mm. 



Launch Camp, Setakwa Eiver, Oct. 1912 (C. Boden Kloss); 1 6 . {Type of the 

 species.) 



Described from a single specimen. 



This species resembles in size and general facies P. carinirostris Pasc. and P. trimastus 

 Heller *, but these insects differ, inter alia, in having the rostrum carinate, the thorax 

 distinctly punctate on the disc and furnished with a well-marked carina on each side, 

 and the elytra differently sculptured.

* This species -was referred doubtfully by Heller to the genus Anehithyrus (Abh. llus. Dresden, siii. no. 3, 

 1910, p. 29, fig. 6) ; it is certainly a Ptolycus.
