some specimens the rufescence “ needs looking for,” and would 
easily escape the notice of a describer who had not seen speci- 
mens having it more defined. 
RHIZOBIUS. 
k. fugax, sp. nov. Ovalis; sat elongatus; modice convexus ; 
pilis pallidis suberectis sat dense vestitus ; sat nitidus ; sub- 
fortiter vix crebre (elytris mediis suturam versus sparsim 
minus fortiter) punctulatus, ferrugineus (elytris, prothoracis 
parte postica mediana, femoribusque apicem versus, picels 
exceptis) ; prothorace quam longiori duplo latiori, antice 
minus angustato, elytris basi vix angustiori, lateribus parum 
arcuatis, angulis anticis rotundatis nullo modo productis, 
posticis fere rectis. Long., 141.; lat., 141. 
The prosternal ridge is narrowed forward, but is not sharply 
pointed at the apex. This character in combination with the 
presence of erect hairs on the elytra, finer and longer than the 
general pubescence brings the present insect near &. Lindi, 
Blackb., from which it differs inter alia by its more elongate 
form and very much coarser puncturation. The puncturation is 
not unlike that of &. Hvansz, Muls., but is distinctly less close, 
and near the suture of the elytra finer. Were it not for this 
latter character I should regard it as possibly a variety of 
Hvansi.

R. dorsalis, sp. nov. Sat late ovalis ; sat convexus ; pilis albidis 
erectis sat dense (nonnullis multo longioribus intermixtis) 
vestitus ; nitidus; supra piceus, prothoracis lateribus et 
elytrorum regione suturali indeterminate rufescentibus ; 
subtus rufescens, antennis palpis pedibusque rufo-testaceis, 
femoribus (presertim posticis) infuscatis; capite pro- 
thoraceque subcrebre minus fortiter, elytris magis fortiter 
nec profunde minus crebre, punctulatis; prothorace quam 
longiori plus quam duplo latiori, antice minus angustato, 
elytris basi vix angustiori, lateribus leviter arcuatis, angulis 
anticis obtusis (certo adspectu rotundatis) posticis rectis. 
Long., 14 1; lat., 9, 1 
A small inconspicuous species, chiefly notable superficially for 
the distinct (but not sharply defined) reddening of the sutural 
region, which seems to be constant. The flattened surface of the 
prosternal ridge is triangular, and very sharp in front. The 
puncturation is strong on the elytra, but considerably less fine 
on the prothorax.
