610 COLEOPTERA. 



striae modoratoly distinct, the general sculpture transverse, crenate-strigose. 

 Pygidiuni covered. 



Femora stout ; intermediate tibiae strongly arcuate ; anterior tarsi 

 with the basal three joints dilated, fourth small, basal joint of the middh; 

 pair thicker than that of the posterior. 



Antennae very similar to those of C. erenatella. 



Underside fusco-rufous, the greyish pubescence suberect on the abdomen, 

 which has six subequal segments. Mesosternum subcarinate, rather long. 

 Metasternum short, so that the intermediate coxae are much more distant 

 from the front than they are from the hind pair. 



The abbreviation of the metasternum, strongly arched middle tibiae, 

 and indefinitely sculptured thorax, in combination, render this easily separ- 

 able from other New Zealand species. 



o. Length (head exserted), 3 mm. ; breadth, \\ mm. 



Rotoiti, Nelson; 5th Februarv, 1916. Unique. Found by Mr. T. 

 Hall. 



4176". Choleva curvigera sp. no v. 



Oblong-oval, somewhat attenuate posteriorly, only moderately convex, 

 nitid ; rufo-castaneous, the labrum, palpi, legs, and basal half of antennae 

 more flavescent, terminal half of thes^ last only slightly infuscate. 



Head trigonal, distinctly punctate, flat in front, with a curved impression 

 extending from behind one antenna to the other so that its back part seems 

 a little elevated, the interantennal and frontal sutures definite and straight. 

 Thorax half as long as broad, its very finely margined sides curvedly narrowed 

 anteriorly, not quite straight behind, apex subtruncate, Avith slightly deflexed 

 rounded angles, the base obsoletely sinuate with only slightly prolonged 

 angles ; disc finely and distantly granulate. Elytra thrice the length of 

 thorax, as wide as it is at the base, tapering gently towards the singly,, 

 well-rcunded apices which do not cover the pygidium ; their sculpture 

 distinct, transversely crenate-strigose, sutural striae obsolete behind, quite 

 definite elsewhere. The body sparingly clothed with elongate decumbent 

 yellowish hairs. 



Tibiae finely setigerous, the middle pair moderately curved. Basal 

 three joints of tarsi cordate, distinctly dilated, and deeply emarginate in 

 front, fourth small, fifth slender, half the whole length. 



No similar species has hitherto been made known. An examination 

 of the head will at once lead to its identification. The antennae no not 

 differ much from those of the preceding species. 



S Length (head exserted), 3 mm. ; breadth, nearly 1 J mm. 



Rotoiti ; 5th February, 1916. A single male only, from Mr. T. Hall, 

 found, like the others, amongst decaying forest-leaves.

 4177. Mesocolon strigicollis sp. no v. 



Oblong-oval, only moderately convex, subopaque ; head and thorax 

 nigrescent and slightly nitid, elytra rufo-fuscous, the legs, palpi, and basal 

 half of antennae fusco-rufous ; covered with slender decumbent ashy 

 pubescence. 



Head trigonal, as broad as thoracic apex, the flat eyes forming the 

 extremities of the laterally prominent basal angles ; it is moderately closely 

 and finely yet quite distinctly punctured. Thorax with the breadth double
