the knowledge of the Cetoniidae of British India 105 



Mhow (Type, coZ/. Janson) ; Poona {coll. British Museum). 



Apart from the very peculiar coloration this pretty 

 species differs from its nearest ally, A. alboguttata, Burm., 

 in its narrower and less convex form, in having the pro- 

 thorax more abruptly narrowed in front, the clypeus more 

 strongly carinate and the pygidium strigose only in the 

 middle. The darker markings on the upper side are pro- 

 duced by the absence of the lighter coloured opaque 

 indumentum, that covers the other parts of the surface, 

 leaving the derm exposed and with a talc-like lustre.* 

 I have named the species after the discoverer, the late 

 Captain R. Selous. 



Clerota rigifica, n. sp. 



Black and very shining above and below, with orange-yellow 

 markings comprising a median stripe on the head, a marginal band 

 on each side and a median stripe on the prothorax, a spot occupying 

 nearly the whole of the scutellum, a broad and slightly sinuous 

 longitudinal stripe on each elytron and a large triangular patch on 

 each side of the pygidium. The sides of the mesothoracic epimera, 

 metathoracic episterna and post-coxae, and a large spot at the sides 

 of the first to fourth abdominal segments are also orange-yellow. 



Head finely and sparingly punctured in the middle, more coarsely 

 punctured in the lateral furrows, clypeus slightly sinuous at the sides 

 and distinctly widened in front. Prothorax almost as broad as the 

 elytra at the base and obliquely narrowed to the apex, broadly 

 sulcate behind, very minutely and remotely punctured at the sides. 

 Elytra slightly narrowed behind and separately rounded at the apex, 

 sulcate at the suture, the middle third of the disc with several rows 

 of more or less obsolete punctures, the sutural stria feeble and 

 becoming obsolete before reaching the middle, the apical third of 

 the sides and the apex very closely and deeply strigose. Pygidium 

 broad and transversely convex, closely and concentrically strigose. 

 Underside of the body almost entirely smooth, the flanks of the 

 prothorax and sides of the basal abdominal segment feebly strigose ; 



* A second specimen from the Shevaroy Hills, Madras, that has 

 since come to the British Museum, has these shining spaces covered 

 to a large extent with a dense white squamose or farinose clothing, 

 which is apparently very lightly attached and easily rubbed off, and 

 in my type specimen is only present to a small extent on the sides 

 of the prothorax and on the pygidium. It would most probably 

 be found that in freshly emerged examples the clothing entirely 

 covered the spaces, so that the markings of the upperside would be 

 white instead of castaneous as I have described them.
