MR. J. S. BALT ON SOME GENERA 
posteriorly, convex, impressed below the base in the S 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 of this species is unknown to me. 
8. Pseudocophora brunnea, Baly, Journ. Linn. Soc. vol. xx. p. 26. 
Oblongo-ovata, postice paullo ampliata, convexa, fulva, nitida, pec- 
tore, abdomine pedibusque posticis quatuor nigris ; elvtrorum limbo 
externo et (in mare ) fovea magna subbasali nigris ; tliorace profunde 
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. 
Fem. Pygidii apice trifido, lobo intermedio elongato, tuberculo acuto 
instructo ; seginento anali late emarginato. 
Hab. 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. brunnea 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. ambusta, Erichs. 
Females of toliicli the Males are unknown to me. 
9. Pseudocophora pectoralis. Ovata, postice ampliata, convexa, 
ilava, 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. 
Fem. Abdominis segmento anali apice profunde emarginato.
