310 Mr. J.S. Baly on the Species of Paropsis. 
This species may be known from its congeners by the much more 
distant punctation of its elytra, also by its subglobular form: it is 
more convex than P. roseola, the highest point of the convexity 
being nearer the base of the elytra. 
Paropsis porosa, Erichs. 
Wiegm. Archiv, 1842, p. 226. 
P. ovata, valde convexa, subtus nigra, nitida ; prosterno, metasterno, linea 
transversa (medio angulata) tibiisque extrorsum flavis; supra flava, 
antennis (articulis basalibus subtus exceptis) verticisque macula nigris ; 
thorace lateribus bisinuatis, angulo antico obtuse mucronato; disco sat 
fortiter irregulariter punctato, ad latera excavato, rugoso-varioloso ; 
elytris subcrebre profunde piceo aut nigro punctatis, interstitiis elevato- 
reticulatis, ad apicem subverrucosis; prosterno ante medium elevato, 
transversim convexo, pone medium bisulecato. 
Mas, Tarsorum anticorum quatuor articulus basalis modice dilatatus, apice 
truncato: edeagus fortiter curvatus, lateribus parallelis, apice rotundato- 
angulato, dente brevissimo vix recurvato armato,—Long. 4-5 lin.

Ovate, convex. Head finely but distinctly punctured ; face separated 
from the epistome by an angular impressed black line, which sends up- 
wards a longitudinal black groove to the vertex, the latter stained with 
a black patch; antenne filiform, black, the basal together with the 
under surface of the three following joints yellow. Thorax rather more 
than three times as broad as long, sides bilobate, rounded at the base, 
anterior angles submucronate; above moderately convex, irregularly 
punctured, sides excavated, coarsely and deeply variolose-punctate. 
Scutellum smooth, impunctate, its outer border sometimes edged with 
black. Elytra very convex, about one-fourth narrower than long; 
shoulders obtusely angled, obsoletely reflexed, their apex rounded; 
sides subparallel in front, slightly sinuate just behind the anterior 
angles; surface somewhat closely covered with deeply impressed round 
punctures, which are more or less stained with black or piceous within ; 
interstices smooth, thickened, subyerrucose towards the apex of the 
elytron. Beneath smooth, black ; pro- and meso-sterna, a large angular 
patch on the metasternum, together with the outer edge of the tibiz, 
shining yellow. 
The form of the prosternum separates this species from all its 
congeners. 
This species is rather variable in size, and is one of the commonest 
in the genus.
