MR. J. S. BALT ON SOME GENERA 



posteriorly, convex, impressed below the base in the cS with a 

 large common fovea, the anterior margin of which is furnished 

 with two obtuse tubercles, placed one on each sutural margin 

 immediately below the scutellum ; general surface of elytra 

 minutely and remotely punctured. 



The 2 this species is unknown to me. 



8. PsEuuocoPHORA BRUNNEA, Bttly, Joum. Linn. Soc. vol. xx. p. 26. 

 Oblongo-ovata, postice paullo arapliata, convexa, fulva, nitida, pec- 

 tore, abdomine pedibusque posticis quatuoi- nigris ; elytrorum limbo 

 externo et {in mare) fovea magna subbasali nigris ; tliorace profunda 

 transversim sulcato ; elytris substriato pone medium confuse punc- 

 tatis. Long. 3 lin, 



Mas. Elytris infra basin fovea magna communi, elevato-marginata, antice 

 bituberculata instructis ; abdominis apice trilobato, lobo intermedio 

 piano. 



Fern. Pygidii apice trifido, lobo intermedio elongate, tuberculo acuto 



instructo ; segmento anali late emarginato. 

 Sab. Malacca; Celebes. 



Thorax nearly twice as broad as long ; sides nearly straight and 

 very slightly diverging from the base to beyond the middle, thence 

 slightly converging to the apex ; disk deeply sulcate transversely, 

 the sulcation rather less deeply impressed on the median line. 

 Elytra sculptured as in P. Wallacei, differing in the number 

 of teeth on the subbasal fovea ; in the present species, as in the 

 preceding two, the anterior margin of the fovea is armed with 

 two obtuse tubercles, the hinder pair being obsolete. 



The male of the present species differs from the same sex of 

 P. uniplagiata, Jac, in the form and sculpturing of the anal 

 segment of the abdomen; in P. hrunnea the median lobe is 

 subquadrate and plane, in P. uniplagiata it is oblong and deeply 

 concave. The coloration of the insect closely resembles that of the 

 typical form of P. amhusta, Erichs. 



Females of which the 3Iales are unknown to me. 



9. PsEUDOCOPHORA PECTORALis. Ovata, postice ampliata, convexa, 

 flava, nitida, pectore abdomineque (hujus apice excepto) nigris; 

 thorace transverso, disco transversim sulcato ; elytris convexis, infra 

 basin non excavatis, distincte punctatis, punctis hie illic subseriatim 

 dispositis. Long. 2\ lin. 



p cm. Abdominis segmento anali a[)ice profunde emarginato.
