L. multisfriafiis, Har. I believe this to be an extremely 
variable species, widely distributed in Northern Australia, and 
L. crenafuJvs, Fairm., pimelioides, Lansb., and perhaps r/lnhi(- 
liformis, Macl., to be synonyms of Harolcrs name. I have 
examined a large number of specimens from numerous locali- 
ties, having the closely striated elytra which distinguish the 
above namird forms from the other named Australian LijKiro- 
chri, and lind among them a wide range of size and n^auy dif- 
ferences in the sculpture of the pronotum, all these differ- 
ences being observable, inter se, among specimens sent in 
batches from a common locality (e.g., in a batch of specimens 
from Port Darwin). According to description crenatulus 
differs from w/idfistriatus in its pronotum being "sat dense 
punctatum," while that of ^nulUstriatus is "in disco parce 
punctatum." I have both forms, and also many intermediate, 
and specimens whose pronotum is devoid of puncturation ex- 
cept close to the lateral margin. L. pimelioides should be 
smaller, with the elytra more dilated behind, and having the 
front angles of the prothorax less acute. A specimen before 
me presents these characters except the last, but, on 
the other hand, I have an example with the 
last-named character very conspicuous, but otherwise 
agreeing with typical mnlfisfriafus. L. glohiiliformis, 
Macl., should be smaller than mvltistriatiis , with the 
pronotum more sparsely punctulate. I have specimens agree- 
ing with the latter character, but have not seen any quite so 
small as the size Macleay gives (long.. If 1., my smallest speci- 
men being 2|- 1.), and this extremely small size perhaps sug- 
gests specific validity. If the characters named as distinguish- 
ing the three forms that have been separated from mvlU^tria- 
tus are to be regarded as valid, several others of the forma 
before me must be treated as distinct species.
