Queensland to an extent that seems scarcely consistent with 
specific identity,—the prothorax being very much more finely 
punctulate and having its sides much more sinuate behind the 
middle. Nevertheless as that eminent specialist Dr. Candéze has 
stated his opinion, after examining a long series of Agrypni from 
various parts of Australia, that he has seen only one species and 
that it is an extremely variable one, I deem it better to abstain 
from treating these Central Australian specimens as specifically 
distinct from J/astersz. 
LACON. 
L. Zietzi, sp. nov. Piceus; minus nitidus ; squamulis piliformi- 
bus griseis vestitus (his in elytrorum interstitiis alternis 
paullo densioribus), antennis pedibusque rufescentibus ; 
prothorace quam longiori vix latiori, crebre subfortiter 
punctulato, canaliculato (canali antice obsoleto), a basi ad 
apicem gradatim (leviter sinuatim) angustato, basi quam 
margo anticus duplo latiori, angulis posticis obtusis extus 
paullo dilatatis; elytris quam prothorax parum latioribus, 
punctulato-striatis, interstitiis subfortiter punctulatis inter 
se eequalibus ; sulcis tarsorum nullis. Long., 5 1.; lat., 121. 
The slightly denser disposition of the vestiture on the alternate 
interstices of the elytra than on the others,—which is more ap- 
“parent in some examples than in others,—gives this species a 
faint appearance of being striped and renders it a little doubtful 
whether Dr. Candéze would place it in his tabulation (Mém. 
Liége (2) IX., 1882, pp. 49, &e.) among the unicolorous or the 
variegated species. Among the former it would stand beside 
L. princeps, Cand., and crassus, Cand., from which its size and 
the posterior angles of its prothorax not truncate readily dis- 
tinguish it,—while among the variegated species it would be at 
once distinguished by the absence of tarsal sulci. It should be 
noted that although careful measurement shows the prothorax to 
be a trifle wider than long, that segment to a casual glance ap- 
pears longer than wide.
