572. Trogophleus transversalis, n. sp. 
7’. niger subnitidus, capite minus crebre, prothorace erebre punctatis, 
hoc postice profunde transversim impresso, elytris postice paulo 
dilutioribus, antennis fusco-piceis basi piceis, pedibus diluto-tes- 
taceis. 
Long. corp. lin. 14. 
T. black, shining, and pubescent. Head and prothorav less rugosely, 
and (especially the former) rather less densely, punctured than in 
the 7’. bilineatus: the latter subcordate, equally punctured nearly 
all over, with a deep transverse impression (rather curved at either 
end) behind, and with the two front fovee (on the disk) almost 
obsolete. lytra ample; rather diluted in colouring posteriorly ; 
and more coarsely, and rather less closely, punctured than the head 
and prothorax, Antenne long, and brownish-piceous ; their base 
being only slightly diluted in hue. Legs diluted-testaceous. 
A most distinct Trogophleus, and hitherto unique,—the single 
example which has as yet come beneath my notice (and which was 
regarded as new by Dr. Kraatz of Berlin) having been taken by 
myself, on the wing, in a cavern of the Southern Dezerta, or Bugio, 
during June 1855. In its comparatively large size and long (though 
basally darker) antenne, it agrees with the 7. bilineatus; but its 
less rugosely punctured, and rather more shining surface, in con- 
junction with its posteriorly diluted elytra, and (above all) the deep 
and well-defined transverse impression on its prothorax behind, will 
at once, apart from other differences, distinguish it from that 
species. 
573. Trogophleus nigrita, n. sp. 
7’. ater subnitidus, capite minutissime ruguloso sed vix punctato, 
oculis prominentibus, prothorace leviter subruguloso-punctulato, 
in disco postico profunde longitudinaliter bi-impresso, antennis 
brevibus fuscis, pedibus piceis, tarsis flavo-testaceis. 
Long. corp. lin. 11. 
T. deep black, slightly shining, and delicately pubescent. Head 
most minutely and densely roughened (or sub-alutaceous), but 
with scarcely any indication of punctures,—even behind ; rather 
smaller (in proportion) than in either of the preceding species, 
with the forehead narrower, and the eyes more prominent. Pro- 
thorax subcordate, lightly subrugulose-punctulate (the punctures 
being small and ill-defined, though rather rougher and larger 
towards either side), and with two deep longitudinal impressions 
on its hinder disk,—which are separated by a rather acute ridge, 
though hardly sufficiently interrupted across to be considered as 
constituting four fovee. Hlytra much more coarsely punctured 
than the prothorax. Antenne short, and fuscous (being darker at:
