it differs in having a larger scutellum, more elongated prothorax and meta- 

 sternum, and the 2nd joint of the funiculus and tarsi more abbreviated. 

 The species are usually larger, less ovate and convex, their rostrum pro- 

 portionally more lengthened, and the anterior 4 coxae wider apart. 

 The species occur in Japan, Malaya, India, New Zealand, (fee. 



Phloeophagosoma corvinum, Wollaston. 941. Man. N.Z. Coleopt^, p. 530. 



Parallel-fusiform, subcylindrical, rather convex, nitid, black. 



Rostrum rather long, parallel, sparingly and minutely punctate. Eyes 

 small, moderately prominent. Thorax triangular-ovate, very slightly con- 

 stricted in front, moderately finely but not closely punctured, more openly 

 along the middle. Elytra subcylindric, narrowed posteriorly, quite as broad 

 as the broadest part of the thorax, behind the middle, evidently punctate- 

 striate, subcrenate-punctate ; interstices moderately convex, subrugulose, 

 sparingly and minutely punctate, the sculpture much less distinct on the 

 posterior declivity. Underside lightly and distantly punctate. Antennae 

 rather slender, rufo-piceous, club subobscure. 



Length, 2J lines ; breadth, f line. 



Tairua. 



P. thoracicum, Wollaston. 943. Man. N.Z. Coleopt., p. 531. 



Nitid, nigro-piceous, elytra piceous. 



Rostrum subarcuate, moderately densely punctate. Thorax moderately 

 coarsely and closely punctate. Elytra truncate at base. 



Like 941 ; thorax larger, a trifle more distantly punctured, elytra more 

 deeply punctate-striate and less biarcuate at the base. 



Length, 2-2J lines ; breadth, f line. 



Parua. 



P. dilutum, Wollaston. 944. Man. N.Z. Coleopt., p. 531. 



Piceous, elytra piceo-castaneous. 



Like 941 ; rather smaller and narrower. Its rostrum, in proportion to 

 its size, a trifle broader, and obsoletely impressed transversely between the 

 eyes, causing it to appear obscurely subdivided from the forehead ; and 

 its scape is more elongated, and extends beyond the apex of the rostrum. 



Length, l|-2^ lines ; breadth, \ line. 



Tairua and Parua. 



P. pedatum, Wollaston. 945. Man. N.Z. Coleopt., p. 532. 



Like the preceding species ; just appreciably less fusiform or more parallel, 

 the vertex with a more distinctly impressed linear fovea, and the 3rd tarsal 

 joint very much wider and deeply bilobed. 



Length, 2| lines ; breadth, f line. 



Auckland and Mokohinau Island. 



P. rugipenne, Broun. 1310. Man. N.Z. Coleopt., p. 738. 



Nude, shining, piceo-niger, legs and antennae rufo-piceous, anterior 

 tibiae along the inside distinctly clothed with fine brassy setae. 



Rostrum parallel, moderately arched, finely but not closely punctured 

 almost as far as the thoracic margin, rather more finely near the apex, the 

 fovea behind the eyes minute. Thorax longer than broad, widest behind 

 the middle ; the sides, however, only very gently rounded ; frontal con- 

 striction distinct ; with a smooth central line, distinctly, rather finely, but
