HORN EXPEDITION—COLEOPTERA. 
Blackb., it ditlers by the carinie ou the upper surface of the rostrum not being at 
their base abruptly raised from the general surface. The elytra scarcely differ 
from those of the same sex in L. t rib ulus, Fab., except in the tubercles being 
throughout a little stronger and the inner row of tubercles having no tendency to 
diverge hindward from the suture. The sculpture of the prothorax is as in 
L. gravis, Blackb., being much coarser and more deeply impressed than in Z. 
tribulus.

Z. tempeensis, sp. nov. (16). Niger; sat nitidus ; squamis albidis vestitus; 
rostro sat convexo, supra longitudinaliter carinato et utrinque leviter sulcato, inter 
oculos profunde foveolato, scrobibus (fere ut Z. tribuU, Fab.) sinuatis bene deter- 
minatis; prothorace crebre punctulato et transversirn crasse confuse rugato, canali¬ 
culate (canali antice abbreviate et ut fovea magna terminate), longitudine latitudini 
lequali, lateribus ante medium rotundato-dilatatis (latitudine majori ante medium 
posita), angulis posticis (superne visis) rectis subdentiformibus; scutello nunuto; 
elytris crassissime seriatim punctulatis, transversirn rugatis (interstitiis longitudi- 
nalibus a transversis hand disparibus), elytro utroque pone medium tuberculis 4 quad- 
ratim positis armato (horum anterioribus 2 majoribus, posteriori-externo minuto 
vel obsolete, posteriori-interno juxta suturam posito), angulis humeralibus acutis 
antrorsum prominentibus. Long. 6—7 1. Lat. 2—3g- 1. 
This species is not very closely allied to any other known to me. It is notable 
for the entire absence of tubercles (except the three or four near the apex of each 
elytron) and costee, the third and fifth interstices however being slightly (in some 
examples scarcely) convex for a short distance at about the middle of their length. 
The punctures of the elytra are large and coarse, separated from each other by 
narrow interstices, which are as distinctly marked transversely as longitudinally; 
the seventh longitudinal interstice forms a marked ridge, owing to the part of the 
elytra beyond it being suddenly declivous. The joints of the funiculus are all 
transverse and subequal in length, the first, however, a trifle longer than the 
others. All the examples before me are much abraded, and to a casual glance 
appear as somewhat nitid, entirely black insects; but the presence of a few small 
patches of white scales on some of them (in variable positions) suggests the 
probability that a perfectly fresh specimen is much clothed with white scales. 
The patch of acuminate conical tubercles near the apex of each elytron varies in 
development; in some examples there are only three distinct tubercles, the postero¬ 
external one being so obsolete as to need looking for, while in others there are
