Mr. J.8. Baly on the Species of Paropsis. 293 
be regretted that H. Stal has added to the confusion by too briefly 
describing thirteen species in the ‘ Ofvers. af K. Vet. Akad. Forh.’ for 
1860; fortunately his insects for the most part are well-marked 
species, so that in the greater number of cases they may be recog- 
nized with tolerable certainty; in some instances, however, it is 
impossible to make out the species intended without reference to the 
author’s types. The descriptions of Erichson (Wieg. Archiv, 1842) 
and Germar (Linn. Ent. vol. iii.) are, as might be expected, clear and 
good as far as they go; but, unfortunately, the great accession of 
new and closely allied forms since the publication of their respective 
works has rendered it not always easy to make out clearly the insects 
to which their diagnoses are intended to apply. 
I propose to divide the genus into two sections, viz. :— 
I. Elytra confuse punctata, seepe tuberculata. 
II. Elytra singula seriebus decem punctorum impressorum imstructa. 
Section I. 
Paropsis variolosa, Marsham. 
Notoclea variolosa, Marsh. Linn. Trans. xii. p. 285. 
P. late ovata, valde convexa, obscure fulva, nitida, antennis extrorsum 
fuscis ; thoracis lateribus ante apicem sinuatis ; elytris punctis brunneis 
aut piceis fortiter impressis, interspatiis (preesertim ad apicem) elevatis, 
hic illic maculis parvis subelevatis lete fulvis instructis. 
Mas. Tarsorum anticorum quatuor articulus basalis modice dilatatus, 
ovatus, apice truncato: edeagus sat elongatus, curvatus, lateribus ad 
apicem angustatis, apice obtuse angulato, paullo recurvato. 
Var. A. Corpore subtus scutelloque piceis.—Long. 6-7 lin. 
Hab. Melbourne, Adelaide, Sydney. 
Broadly ovate, very convex. Head deeply but subremotely punc- 
tured; face separated from the clypeus by an angular groove, from the 
apex of which a grooved line runs upwards to the vertex; antennee 
filiform, longer than half the body. Thorax scarcely three times as 
broad as long; sides obtusely rounded, suddenly converging and deeply 
sinuate at their apex, anterior angles submucronate; above transversely 
convex, disk distantly covered with deep round punctures irregularly 
crowded here and there over its surface; sides deeply and irregularly 
excavated, variolose-punctate. Scutellum subtrigonate, sides slightly 
rounded, shining, impunctate. Elytra one-fourth longer than broad, 
on the other hand, all useless and too brief diagnoses, insufficient at any time to 
characterize the species or separate them from their congeners, ought to be 
entirely ignored, and the names given by the authors be looked upon in the 
same light as simple manuscript ones. This rule I would apply to many of the 
loose descriptions of Boisduval and other authors.
