ADELIUM. 
Adelium multistriatum, n. sp.—Oblongum, parallelum, ceneum, pedibus piceis, 
antennis tarsisque rufescentibus, prothorace subquadrato, crebrius fortiter punctato 
elytris regulariter fortiterque striatis, striis crebrius punctatis, interstitiis augustis. 
Long. 12 m.m. 
This is closely allied to A. thoracicum, and has a similar sculpture ; the thorax, 
however, is not conspicuously narrowed behind, and the elytra are remarkable by 
their deep, regular striation, the striae being very closely punctured, and the inter- 
stices narrow and rather convex. The punctuation of the thorax is similar to that 
of A. thoracicum, but rather more dense, and the sculpture of the vertex 1s 
decidedly rugose. 
Picton. Helms, one mutilated example. 
Adelium simplex, n. sp.—/Eneo-nigrum, nitidum, pedibus piceis, antennis 
tarsisque rufis, prothorace subquadrato, lateribus subrectis, postice tantum 
lenissime angustato, crebre subtiliter punctato, intra latera depressiusculo; elytris 
multistriatis, sat fortiter punctatis, Long. 9 m.m. 
Head closely, moderately finely punctate. Thorax about one-fourth broader 
than long, rather closely and moderately finely punctured, the sides a little 
depressed close to the lateral margin, this latter rather broad, the hind angles 
rectangular. Elytra with series of punctures placed in striz, the punctures coarse, 
so that the striation is not very distinct; with one or two spots on the disc where 
the strize become disorganized; the interstices almost impunctate. In addition to 
the punctuation the head and thorax have a few vague larger impressions irregu- 
larly placed, and, perhaps, abnormal. 
Christchurch. Wakefield, one example. I sent this to Mr. F. Bates some years ago, and he 
returned it as unknown to him. It should be placed near A. thoracicum. A, eratum Broun appears 
from the description to be a closely allied species with differently sculptured elytra. 
Adelium sericatum, n. sp.—Oblongum, subdepressum, subnitidum, eeneum, 
pedibus piceis, antennis tarsisque rufis; prothorace subquadrato, crebre subtiliter 
punctato, elytris seriatim punctatis, interstitiis latis sparsim minus subtiliter 
punctatis. Long. 9-10 m.m. 
This is closely allied to A. simplex, though readily distinguished by the less 
shining surface, and by the much finer punctuation of the wing-cases, which are 
only very feebly striate, the outer series being very obsolete ; when compared with 
A, simplex, the striz are really as numerous (about fifteen) as they are in A. 
simplex, though owing to their greater fineness, and to the broader interstices, and
