below the palps cavity which are very broad ; maxillae short, robust, 

 upper lobe with a bifid tooth and densely penicillate outwardly, apex 

 of inner lobe slightly mucronate ; last joint of labial palps swollen 

 outwardly, that of the maxillary short ; head small, clypeus truncate, 

 angles moderately rounded , antennae 10-jointed ; eyes very large ; 

 prothorax very diagonally attenuated laterally in the anterior part, 

 much less so in the posterior ; base straight laterally, strongly 

 arcuately emarginate above the scutellum ; the latter very long, 

 narrow, not sharply acuminate at apex; elytra plane, broader than 

 the prothorax at the base, slightly attenuate behind, with the suture 

 sharply acuminate (glaberrimus) ; propygidial spiracle small but 

 sharply conical; pygidium sloping backwards; mesosternum divided 

 from the metasternum by a very distinct suture, mesosternal process 

 very broad, transverse, almost straight at apex ; prosternum with a 

 long, vertical spine-like ante-coxal process truncate at apex; anterior 

 tibiae sharply tri-dentate outwardly, intermediate and posterior ones 

 with a spine on the upper side ; tarsi somewhat slender and 

 moderately long. 



West wood originally founded this genus for a very singular species 



from Guinea (to which he added another later on), and which, like 



Uloptera planata, Burm., an allied genus, from Cayenne, has 



10-jointed antennae, instead of these being 9-jointed as in all the 



other known Cetonince. 



Phymatopteryx glaberrimus, Westw., 

 Trans. Ent. Soc, 1879, p. 202, pi. 3, fig. 4. 



Very shiny, brown, glabrous ; prothorax and elytra variegated 

 with dull flavescent ; head flavescent, sides including those of the 

 clypeus longitudinally impressed, and closely punctate ; prothorax 

 dull flavescent, but with the median part piceous brown, in the 

 central part of the disk which is impunctate is a short, punctate 

 impression, three deep strigillate ones on each side of it, and two 

 supra-lateral ones, the base is sloping towards the scutellum, but 

 with the angles distinct, and deeply arcuate above the scutellum, 

 the dorsal space between the discoidal impression is smooth, but the 

 sides are strigillate ; scutellum impunctate, but slightly impressed 

 at the base, and sub- strigillate there ; elytra with a dorsal, wavy, 

 sub-tectiform costule and a less distinct one near the deflexed part ; 

 the space between the first dorsal costule and the suture is filled in 

 the anterior part by an elongated impression running beyond the 

 point of the scutellum, and with a single juxta-sutural stride, in 

 the posterior part there is a similar impression reaching the apex,
