1156 COLEOPTEBA 



2049. A. Simplex, n.s. (Sha-iy; Trans. Boy. Dub. Soc., 1886, 

 p. 409.) j&neo-nigrum, nitidum, pedibus piceis, antennis tarsisque 

 rufis, prothorace subquadrato, lateribus subrectis, postice tantum 

 lenissime angustato, crebre subtiliter punctate, intra latera depres- 

 siusculo ; elytris multistriatis, sat fortiter punctatis. 



Long., 9mm. . 



Head closely, moderately finely punctate. Thorax about one- 

 fourth broader than long, rather closely and moderately finely 

 punctured, the sides a little depressed close to the lateral margin, 

 this latter rather broad, the hind angles rectangular. Elytra with 

 series of punctures placed in striae, the punctures coarse, so that the 

 striation is not very distinct ; with one or two spots on the disc where 

 the striae become disorganized ; the interstices almost impunctate. 

 In addition to the punctuation the head and thorax have a few vague 

 larger impressions irregularly placed, and, perhaps, abnormal. 



Christchurch. Wakefield ; one example. I sent this to Mr. F. 

 Bates some years ago, and he returned it as unknown to him. It 

 should be placed near A. thoracicum. A. aratum, Broun, appears 

 from the description to be a closely- allied species with differently- 

 sculptured elytra. 



2050. A. Sericatum, n.s. (Sharp ; Trans. Roy. Dub. Soc., 

 1886, p. 409.) Oblongum, subdepressum, subnitidum, aeneurn, 

 pedibus piceis, antennis tarsisque rufis ; protlwrace subquadrato, 

 crebre subtiliter punctate, elytris seriatim punctatis, interstitiis latis 

 sparsim minus subtiliter punctatis. 



Long., 9-10mm. 



This is closely allied to A. simplex, though readily distinguished 

 by the less shining surface, and by the much finer punctuation of 

 the wing-cases, which are only very feebly striate, the outer series 

 being very obsolete; when compared wdth A. simplex the striae are 

 nearly as numerous (about fifteen) as they are in A. simplex, though, 

 owing to their greater fineness, and to the broader interstices, and 

 to the fact that the sides of the elytra are more deflexed, they 

 appear at first to be fewer. There is but little difference in the 

 front tarsi of the two sexes. 



Dunedin. Professor Hutton. 



2051. A. intermedium, ?'s- (Sharp; Trans. Roy. Dub. Soc., 

 1886, p. 410.) Oblongum, subdepressum, nigro-aeneum, parum 

 nitidum, antennis fuscis, tarsis rufis ; protlwrace subquadrato, sub- 

 tiliter marginato, crebre subtiliter punctato ; elytris crebre punctatis, 

 obsolete striatis. 



Long., 8mm. 



This greatly resembles A. zealandicum, but is much less densely 

 punctate, and the fine depressed pubescence of that species is 

 represented in A. intermedium by a setosity that is so extremely 

 minute that it can be only detected with a high power ; the striae 

 are quite as obsolete as they are in A. zealandicum. 



Bealey. Helms ; a series of six examples.
