406 Suare—On New Zealand Coleoptera. 
Fam. TENEBRIONID &. 
PsEUDOPATRUM (noy. gen. Helopinorum), 
Antenne subclavate articulo 3° elongato, ad basin tectee; oculi transversi 
margine anteriore curvyato. Pseudepiplurz latissimee acute inflexee ad ventri 
marginem grosse profundeque foveolate. Tarsi graciles, subtus satis pubescentes ; 
tibize calearibus brevibus ; coxze posteriores valde distantes, extus brevissimee. 
This genus is proposed for Opatrum tuberculicostatum, White (and a very closely 
allied species), and is of an anomalous character, so that its true position is very 
doubtful. The clypeus is emarginate in front, and the much-exposed labrum has its 
front margin of similar shape ; the antennary orbit is rather strongly elevated, and 
is laterally more prominent than the eye. The last joint of the maxillary palpus is 
securiform. The mentum is moderately large, and the ligula visible at its extre- 
mity. The sides of the thorax are dilated and explanate. The front cox are 
small, globular, moderately distant, the process separating them flat, not promi- 
nent. The posterior portion of the mesosternum is more prominent (1.e. on a 
different plane) than the anterior, but not at all impressed, the middle coxe are 
moderately distant, globular, their trochanter rather small. The metasternum is 
short, and the hind coxe so widely separated that they are very abbreviated in 
their transverse dimension. The most remarkable character is the great develop- 
ment of the pseudepipleuree, which, moreover, are so acutely inflexed that their 
existence would not be suspected from an inspection of the upper surface, and along 
the sides of the ventral segments they bear a series of extremely remarkable foveee. 
The legs are elongate and slender, the tibize quite slender, and with two short but 
distinct spurs. The tarsi are all slender, the pubescence is on the basal joint 
divided by an impressed line, the penultimate is a little prolonged beneath the 
terminal joint. 
The most natural position for this genus is, in my opinion, near Adelium and 
Cilibe ; the form of the eyes and the concealed insertion of the antennz remove it 
considerably from Pascoe’s Syrphetodes, and from the extremely curious genus 
Paraphylax Broun, which is remarkable on account of the neck of the mesothorax 
being greatly and abruptly below the level of the base of the elytra. 
Pseudopatrum sordidum, n. sp.—Fuscum, opacum, depressum, prothoracis 
lateribus explanato-elevatis ; elytris per paria striatim minute asperato-punctatis, 
inter paria hic inde vix tuberculatis, ante apicem tuberculis parum elevatis. Long. 
12 m.m. 
This is extremely similar to White’s O. tuberculicostatum, but the remarkable 
sculpture of that insect is present here in a rather more rudimentary condition, the 
head is not so broad and the antennee are not so elongate. The surface is sparsely
