348 Mr. C. 0. Waterliouse on a new Species ofCetoniida?. 



XLIII. — Descrip)tion of a new Species of the Coleopterous 

 Family Cetoniidfeyy-ow Madagascar. By Chas. O. Water- 

 HOUSE. 



Stenotarsia punctiventris, n. sp. 



Nigra ; thorace sanguiuv'^o, maculis duabus nigris, scutello sanguineo ; 

 elytris obsolete striato-punctatis,sanguiueis, singulo macula parva 

 discoidali nigra. 5 • Long. 6 lin. 



Head velvety black ; clypeus shining, closely and ratlier 

 strongly punctured, the apex distinctly and acutely incised. 

 Thorax narrower than the elytra, more convex than in its allies, 

 somewhat circular in outline, very sliglitly narrowed at the 

 anterior angles, which are not produced ; the margins not 

 incrassate, fringed with black hair. On the disk behind the 

 middle are two small, round, widely separated^ black spots. 

 Scutellum rather large, nearly an equilateral triangle. Elytra 

 somewhat depressed, slightly narrowed towards the apex, the 

 apical callosity very obtuse. Each elytron has four somewhat 

 irregular indistinct lines of punctures, and on the disk a 

 round black spot, placed a little nearer to the suture than to 

 the side, and a trifle nearer to the base than to the a])ex. 

 Sides of the metasternum and of the abdomen rather strongly 

 vermiculate-punctate. Legs robust, strongly punctured. 

 Pygidium moderately convex, about one quarter broader than 

 long, opaque, rounded at the apex, the apical margin narrowly 

 reflexed and shining ; the rest of the surface is moderately 

 thickly but obscurely punctured. Anterior tibia3 rather broad, 

 armed with two teeth, i.e. one besides the apical projection. 



This species most nearly resembles Stenotarsia Scottii, 

 Janson, in general form, but the black spots on the elytra are 

 differently placed. It is possible that it may be S. crocata^ 

 G. & P. (known to me only from description) ; but in that 

 case the expression " clypeo parum exciso " is very mis- 

 leading, as the clypeus is much more incised than in the allied 

 species. The legs are more robust. 



Hah. Madagascar. 



Dr. Kraatz places S. Scottii in his genus Linotarsia^ with 

 ;S'. discoidalis and S. picta, Waterh. As the genus Linotarsia 

 is separated from Stenotarsia chiefly on account of the form 

 of the thorax, I am rather at a loss to understand why these 

 three species are associated, S. discoidalis having the thorax 

 narrowed in front with porrect anterior angles. S. Scottii has 

 the thorax almost circular ; and S. picta has it constricted 

 before the base, with diverging posterior angles.
