OF NEW ZEALAND. 1151 



prominent and acute ; apex sinuously elevated at the middle ; sides 

 straight, but narrowed from the middle forwards, sinuously narrowed 

 behind, posterior angles a little projecting ; base with an excision 

 near each side, so that the angles do not touch the elytra. Scutel- 

 him very transversal. Elytra nearly double the width of thorax, 

 shoulders obtuse ; sides explanate, each with about ten foveas ; 

 dorsum with rows of moderate punctures, also two basal and four 

 discoidal elevations, besides twelve on the summit of hind slope, 

 two of which are considerably larger than the others ; there are two on 

 the slope itself ; the apices are almost tuberculate, leaving a sutural 

 gap; a raised space behind each shoulder terminates at the side, 

 but is pointed upwards rather than outwards. Femora densely 

 covered with yellowish scales, tibiae scarcely spotted. 



This does not exactly accord with the description and figure of 

 the typical species. Dr. Sharp's S. bullatus differs in several 

 respects, such as " sides of elytra but little explanate, lateral outline 

 undulate," &c. S. marginatus has a shorter and more elevated elytral 

 disc.

Antermce subclavatae articulo 3 elongato, ad basin tectae ; oculi 

 transversi margine anteriore curvato. Pseudepipleura latissimae 

 acute inflexae adventri marginem grosse profundeque foveolatae. 

 Tarsi graciles, subtus satis pubescentes ; tibia calcaribus brevibus ; 

 coxce posteriores valde distantes, extus brevissime. 



This genus is proposed for Opatrum tuber culicostatum, 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 extremity. The sides of the thorax are 

 dilated and explanate. The front coxa are small, globular, mode- 

 rately distant, the process separating them flat, not prominent. 

 The posterior portion of the mesosternum is more prominent (i.e., on 

 a different plane) than the anterior, but not at all impressed ; the 

 middle coxae are moderately distant, globular, their trochanter 

 rather small. The metasternum is short, and the hind coxae so 

 widely separated that they are very abbreviated in their transverse 

 dimension. The most remarkable character is the great develop- 

 ment of the pseudepipleura, 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 foveae. The legs are elongate
