differs from sinwatus, Blackb., inter alia by its prothorax with 
less strongly rounded sides and narrower in proportion to the 
elytra.

LONGICORNES. 
YORKEICA (gen. nov. Phoracanthidarum). 
Palpi subzequales sat breves robusti, ad apicem truncati ; caput 
breve ; antenne quam corpus parum longiores (articulis 1° 
subpiriformi, 2° brevi, 3° quam 1"* paullo longiori, 4° quam 
L"s vix longiori, 5° quam 3°° sublongiori, ceteris longioribus, 
11° appendiculato), articulis 3—7 ad apicem utrinque 
spinosis (spina externa quam interna majori); oculi sat 
grosse granulati; prothorax inermis; elytra ad apicem 
bispinosa ; pedes antici quam posteriores multo breviores ; 
femora sat lineares ; tarsi sat breves, articulo basali quam 
latiori vix duplo longiori, quam sequentes 2 conjuncti sat 
breviori, unguiculi divergentes ; coxe intermediz clause. 
The position of this genus is very difficult to determine. 
According to Lacordaire’s classification it is a Phoracanthid on 
account of the strongly granulated eyes, spined antenne, and 
closed intermediate coxal cavities ; therefore I place it among the 
Phoracanthid genera.* Butits prothorax unarmed at the sides 
and scarcely tuberculate above, and its short tarsi (with the basal 
joint distinctly shorter than the following two together, and the. 
claw joint very little shorter than the preceding three together) 
separate it very widely from all other Phoracanthides known to 
me, and are almost Lamiid in appearance. The front legs very 
short in comparison with the four hinder legs perhaps suggest an 
atlinity to the genus Xypeta, Pasc., but, otherwise, it does not 
seem to resemble X. grallaria, Pasc. I am not sure of the sex. 
of the type, but think it probably a female. 
Y. marmorea, sp. nov. Picea, pube cinerea et fulva marmorata ; 
prothorace leviter transverso, in disco ante medium tuber- 
culis parvis nonnullis instructo, lateribus leviter arcuatis ; 
elytris antice sat grosse punctulatis et tuberculis plurimis 
nitidis parvis armatis, postice sparsim minus _profunde 
punctulatis nec tuberculatis. Long., 16 1.; lat., 5 1. 
The markings resulting from the presence of ashy and fulvous 
pubescence on the piceous derm are extremely intricate. On the 
head an ashy line runs down the middle, a fulvous line runs 
* Since this was written Mr. Gahan,—to whom as an eminent specialist 
on the Lengicornes I submitted my specimen for inspection,—has favored 
me with his opinion that Yorkeica is correctly placed in Phoracanthides as. 
anew genus. He thinks it near Demelius.
