1947. P. longulus, n.s. {Sharp; Trans. Boy. Dub. Soc, 1886, 

 p. 389.) Elongatus, angustulus, nitidus, piceus, antennis pedibusque 

 rufis ; interdum rufescens ; antennarum clava evidenter divisa ; pw- 

 thoracc angustula, angulis anteriovibus nullo modo prominulis, disco 

 vage impresso ; elytris striatis, striis fortiter punctatis, interstitiis 

 planis. 



Long., 3imm. 



AntanncB moderately stout; tliorax narrowed behind, slightly 

 longer than broad, closely and coarsely punctate, the disc vaguely 

 depressed, the depression duplicate behind, single in front. Shotdders 

 of elytra free, not at all prominent. 



This is closely allied to P. minor, though very distinct by reason 

 of the evidently-divided club of the antenna. It is also more elon- 

 gate, and the thoracic impression is a little less obsolete. I do not 

 think the rufescent form is distinct from the dark one.

1948. P. helmsi, n.s. {Sharp; Trans. Boy. Dub. Soc, 1886, 

 p. 389.) Parum elongatus, nitidus, piceus ; capite elongato, oculis 

 minoribus ; j^^'othorace oblongo, disco impressione magna et profunda 

 anguste divisa ; elytris sulcatis, sulcis leviter flexuosis, baud punc- 

 tatis, post scutellum trtinsversim depressis. 



Long., 3^-mm. 



Antennce stout, with club large and only very indistinctly divided, 

 the terminal or pubescent portion small ; head densely punctate : 

 thorax scarcely perceptibly narrowed behind the sides, a little con- 

 tracted near the front angles, which are not prominent, the surface 

 shining but rather closely and coarsely punctate, the disc occupied 

 by a large and deep oblong depression, which is only divided by a 

 slight carina along the middle : elytra with very deep striae, which 

 are not sculptured, though their edges are a little fiexuose, the base 

 is emarginate but the humeral angles are not acute, and immediately 

 behind the scutellum the surface is depressed : vietasternum rather 

 short. 



This interesting species is an intermediate form between the 

 normal and ordinary New Zealand Pycnomeri, as represented by 

 P. sophorcs, and the blind forms of wlrich P. sulcatissimus may be 

 taken as the type. The only examples I have seen are the three 

 sent by Mr. Helms, after whom I have consequently named it. 



Grey mouth. 



1949^ P. sulcatissimus, n.s. {Sharp; Trans. Boy. Dub. Soc, 

 1886, p. 389.) NujerrinLUs, nitidus, oculis minutis, antennis pedibusque 

 rufis ; prothorace oblongo, fortius punctato, disco profunde impresso, 

 impressione anguste divisa ; elytris profunde sulcatis, sulcis leviter 

 flexuosis. 



Long., 3|^mm. 



This IS distinguished amongst the allies by the very deep oblong 

 impression on the middle of the thorax, which is divided only by a 

 narrow carina, extending all along the depression, but less distinct 

 m its anterior part. The eyes are very minute, but still are very
