OF NEW ZEALAND. 1011 



shallow. Thorax transverse, sides curved, narrowed but not sinuate 

 behind ; hind angles extremely obtuse, median channel subobsolete, 

 basal impressions very obscure. Elytra narrow, humeral angles 

 rounded, lateral margin well marked, apices subtruncate, without 

 punctuation, but under a half-inch power appearing finely reticulate, 

 studded with minute setae, especially on the lateral margins. Front 

 tibia stout. 



This is one of the most minute of the Carabidce, and its almost 

 blind condition renders it possible that it may be one of a group of 

 species with subterranean habits, analogous to the minute European 

 Scotodipni and Anilli. I obtained it some years ago from Herr 

 Eeitter, and I expect that when specimens come to hand to enable 

 it to be thoroughly investigated it will prove to be sufficiently 

 generically distinct. I cannot place it in Scotodipnus HOT Anillus, 

 though it is apparently nearer to the former than to the latter of 

 these two genera ; and, as it has somewhat the form of the New 

 Zealand Cillena, I associate it provisionally with them. The robust 

 front legs are rather remarkable in so minute and fragile an insect, 

 but do not indicate any real affinity with the Dyschirioid genus 

 Reicheia, which consists also of minute blind species. 



Greymouth. Helms, ex Eeitter. 



OBS. This species is either the same as my Anillus pallidus or 

 else very closely allied thereto. Dr. Sharp's description of Cillenum 

 bates is not transcribed, as it is identical with Cillenum chalmeri 

 (No. 1568). T.B. 



Tachys. 



1812. T. latipennis, n.s. (Sharp; Trans. Boy. Dub. Soc., 

 1886, p. 374.) Testaceus, plus minusve picescens, nitidus; antennis, 

 palpis, pedibusque testaceis ; prothorace cordato, angulis posteriori- 

 bus rectis ; elytris striis duabus ad suturam sat profundis, striaque 

 tertia minus distincta. 



Long., 2-24-mm. 



Antenna feeble, second joint elongate, longer than third. Eyes 

 small, head bi-impressed between them, the impressions rather 

 widely separated. Thorax a little curved at the sides, narrowed 

 and sinuate behind, the hind angles sharply denned, exactly rect- 

 angular. There is a rather fine channel along the middle, and a 

 fovea at the base on each side. The elytra are broad and short, 

 with the shoulders perfectly rounded. The sutural stria is deep, 

 and extends to the apex. The second stria is also rather deep, but 

 does not extend on to the apical portion; and there is a third 

 indistinct stria. The striae external to these are almost entirely 

 obliterated. The apical plica is very distinct, and there are two 

 obsolete setigerous punctures on the third interstice. The oblique 

 truncation of the anterior tibia is excessively slight.
