HORN EXPEDITION — COLEOPTERA.

lono^itudinal intervals devoid of punctures here and there, these intervals, however, 
in some examples scarcely traceable, and not well marked in any example that I 
have seen. It is, however, a much less convex species than most of those in 
Groupe II. It is a very arbitrary division which places this insect and 
r. JVaterhousei in different groups ; but still it is highly convenient to break 
Paropsis up into groups, and if this is to be done an artificial line must be drawn 
somewhere, and I think it is best drawn by regarding JVa^erhot/sei as near the end 
of the first group and the present species as near the beginning of the second.

This species is a member of Dr. Chapuis’ “ Groupe II.” In form it is shorter 
and wider than P. seviipunctata, Chp , but not nearly so globular as P. hemisphcericn, 
Clip. A well-marked character consists in the comparatively broadly thickened 
margin of its elytra, which is even a trifle more defined than in P. semipimctuta. 
The form of its prosternum is also characteristic but less reliably, as in some 
specimens the sulcus of its posterior portion is continued nearer to the front of the 
prosternum than in others. In this species as compared with P. hejnisphcErica, 
Clip., the puncturation of the prothorax is much less close, while on the elytra the 
larger punctures are very similar and very similarly distributed, but the small 
punctures are very much more sparse. The longitudinal non-punctulate spaces are 
scarcely discernible. The width of the elytra (measured on the underside) is almost 
equal to the distance from their apex to the front of the prosternuni. The sexual 
characters (apart from those common to all its congeners) seem very slight, the 
female, howevei’, being a trifle narrower and generally a little larger than the male.
