Bothrideres mastus, n. sp. 
B. niger, subopacus, antennis, tarsisque rufescentibus ; prothorace sub- 
quadrato, fortiter punctato ; elytris apicem versus costatis. Long. 
corp. 4} m.m. 
Nearly as large as B. contractus.. Antenne dark red ; joints 3-9 small, 
10 and 11 forming a broad club, the eleventh nearly as broad as the tenth. 
Head ratherly coarsely punctured. Thorax quite as long as broad, nearly 
straight at the sides, these not being rounded in front and only very slightly 
narrowed behind the middle; the surface is a little uneven, but has no 
distinct impression, it is rather coarsely punctured, the punctures about the 
middle being irregularly distributed, Elytra with the alternate interstices 
narrowed, and a little elevated towards the extremity, and bearing rather: 
fine punctures. Underside rather coarsely punctured. Legs slender. 
A single specimen has been sent me from Tairua by Captain Broun. 
This species has the intermediate joints of the antenne more slender and 
the club broader than in B. contractus, the legs more slender, and the 
thorax differently shaped. 
Pycnomerus sophora, n. sp. 
P. elongatus, parallelus, piceo-niger, subopacus ; prothorace dorso im- 
presso, impressione posterius minus distincte divisa ; elytris suleatis, 
suleis punctatis, punctis distantibus. Long. corp. 81-44 m.m. 
Antenne distinctly eleven-jointed, the eleventh joint a good deal nar- 
rower than the tenth. Head very coarsely punctured, with a very deep 
impression on each side in front, the outer margin of which is continued 
backwards close to the eye as an elevated fold. Thorax about as long as 
broad, slightly narrowed behind, coarsely and closely punctured, with a 
rather large impression on the middle, the posterior part of which is indis- 
tinctly divided into two. Elytra bearing deep broad stris or grooves, at the 
bottom of which are deep punctures separated from one another by a-long 
raised interval; the interstices between the strim are narrow, elevated, and 
impunetate. Underside closely and very coarsely punctured. 
Sent from Tairua by Captain Broun, and indicated as found in the wood 
Sophora tetraptera. 
This species is variable in size; and the small individuals are often not 
so dark in colour as the larger ones. These smaller individuals therefore at 
first sight much resemble the following species, from which they can always 
be distinguished by the different impression on the thorax, and the more 
widely separated punctures of the stria of the elytra. 
Pycnomerus simulans, n. sp. 
P. piceo-niger, parallelus ; prothorace dorso longitudinaliter haud pro- 
funde biimpresso ; elytris sulcatis, suleis punctatis, punctis approxi- 
matis. Long. corp. 8] m.m.
