able to decide this point definitely, and states that §. vzttatwm is

TESSAROMMA. 
T. nanum, sp. nov. Subtus piceum, metasterno dilutiori ; supra 
piceum, capite prothoracis parte antica-mediana et elytris 
postice indeterminate rufescentibus, antennis palpis pedibus- 
que (femorum parte clavata obscura excepta) rufo-testaceis ; 
setis fulvis erectis sparsis instructum, elytris pube argenteo- 
sericea maculatim ornatis ; capite confertim subtiliter aspere 
punctulato, linea longitudinali mediana vix perspicue impresso ; 
antennarum articulo 3° leviter arcuato; prothorace quam 
latiori perspicue longiori, antice posticeque leviter constricto, 
ad latera media spinoso, dorso longitudinaliter bicristato, 
cristis a margine antico fere ad basin continuis; elytris 
basin versus sparsim granulatis, ad ‘apicem rotundato- 
truncatis. Long., 34 1. ; lat., 1 1. (vix). 
At once distinguishable from its previously described congeners 
by, znter alia, its much more slender legs and antenne, its head 
not impressed with a well-defined median longitudinal furrow, 
its prothorax with (the ill-defined pair of median gibbosities of 
the other species represented by) two well-defined elevated longi- 
tudinal crests, which are quite traceable to the front margin, 
_ though much more feeble (and also more widely separated from 
each other) on the part in front of the anterior constriction than 
behind it (in fact the crests on that part ought perhaps to be 
described rather as isolated sub-obsolete crests not quite in line 
with the larger ones), and its elytra with spots of silvery pubesence 
similar to those of P. wndatwm in the front two-thirds of their 
length, but having the apical one-third densely and quite 
uniformly clothed with the pubescence. The very small size of 
this species, of course, also distinguishes it. The two divisions 
of the eyes are very widely separated from each other, and coarsely 
granulated. Viewed from the side the gibbosity of the prothorax 
is markedly greater than in either wndatum, Newm., or 
sericans, Er.
