(Kirby, Zool. Journ. iii. p. 271, 1827. Ptychophorus, Schaum, Germar Zeitschr. ii. 271.) 
Corpus parvum subgracile oblongo-ovatum. Clypeus antice marginatus sed non reflexus. Mandibule parte 
externa cornea extus rotundata apice acuto recto, ultra partem internam producto. Maxille elongate galea 
curvata apice acuto integro; mandonis dente apicali plus minusve fisso seu bispinoso (pl. VIII, fig. 5a). Men- 
tum oblongum, disco ante medium angulato, parte antica suboblique truncata, swpe valde setosa (fig. 5 4). 
Prothorax subhexagonus, ante medium versus caput, angustatum, pone medium lateribus fere parallelis, postice 
biimpressum. Prosternum in spinam acutam deflexam ante coxas anticas productum. Mesosternum in pro- 
cessum brevem subtruncatum productum. Elytra singula costa elevata irregulari in disco notata. Abdomen 
segmentis 2, 3 et 4 basalibus suleo longitudinali notatis. Spiracula postica magna conoidea. Tibie antice 
maris extus inermes, foemine extus ad apicem dilatat bifide. 
I consider the reasons given by Schaum for the rejection of Mr. Kirby’s generic name insufficient. The 
Lepidopterous name Cymatophora is sufficiently distinct from Mr. Kirby’s, and it occurs in a different order of 
insects. The rejection of a generic name in one order or class, because it is already employed in another, would, 
in the present state of science, involve the change of hundreds of names well known and generally adopted. 
The species of this genus are of small size, with the middle of the dise of each elytron raised, forming 
a polished costa, between which and the suture are several fine strixv. The elytra are also generally marked 
with small white silky spots. The species appear to be confined to Africa. 
Specres 1 (21)—CYMOPHORUS HILARIS. 
Pratt VIII, Fre. 10. 
Oblongo-obovatus, supra parum convexus; niger nitidus; antennis ferrugineis; prothorace sat crebre 
punctato, basi utrinque impressa; scutello punctato, medio lwvigato; elytris luteis, subtiliter parce punctatis ; 
intus bistriatis, unicostatis, in disco exteriore biimpressis, sutura fere ad apicem late nigra, nigredine medio 
utrinque ampliata, abdomine toto dilute sanguineo. 
Long. corp. mill. 6-9; lat. 3-4 mill. 
Habitat ; tractus fluvii Limpopo dicti, Caffraria. In Mus, Holm. (mihi pro delineatione communicatus). 
Syn. : Ptychophorus hilaris. Westw. MS; Schaum, Verz. Lam. Melit. p. 60; Boheman, Ins. Caffr. pars ii. p. 48. 
This pretty species is distinguished not only by its orange-coloured elytra, with a broad irregular black 
sutural mark, but also by the hind part of the prothorax not being narrowed at the shoulders. The clypeus has 
the sides, and especially the front margin, elevated ; the head and pronotum are finely punctured ; the sides of 
the elytra strongly punctured; the humeral and discoidal impressions of the latter are striolated; the disc 
glossy and finely but distantly punctured. The body beneath is shining; the sides of the metasternum strigosely 
punctured ; the abdomen blood red and glossy, with an oval central impression extending over the second, third, 
and basal half of the fourth segments. The maxillie have the galea acute and slightly curved, and the mando 
armed with two nearly equal acute teeth. The mentum is oblong, nearly straight along the fore edge, behind 
which it is obliquely truncated, so that the anterior part, seen laterally, is outwardly angulated. The anterior 
tibis in the female are slightly notched below the apex (fig. 10) rather than bidentate. The anterior process 
of the metasternum is thickened between the middle feet, and porrected towards the hind part of the prosternum.
