82 MR. r. p. PASCOE ON THE LONGICOEIirrA or ATJSTRALIA. 



This species has long stood in our collections as Sebecerus 

 sparsus, Eeiclie, a name, I believe, never published. It is related 

 to H. Germari, but, inter alia, it has a longer scape, and the pro- 

 thorax has not the white stripe at the side. 



Neissa. 

 Caput antice transversum, tuberibus antenniferis brevibus. OcuU late 

 emarginati. Antennce sparse pilosse, corpore longiores ; scapo modice 

 elongatOj apicem versus sensim crassiore, articulo tertio quam scapus 

 paulo breviore, quarto prsecedenti sequali, cseteris gradatim decrescen- 

 tibus. Prothorax capite vix latior, quadratus, utrinque abrupte spi- 

 nosus. Elytra oblonga, basi cristata, lateraliter deflexa, apice Integra. 

 Pedes subbreves, sequales. Pro- et mesosterna simplicia. 



A small species, resembling Pentacosmia scoparia in habit and 

 colour, is the type of this genus. From Pentacosmia, however, it 

 differs in its quadrate prothorax, basal crests of the elytra, an- 

 tennae with the third joint not longer than the scape, the fourth 

 equal to the preceding, and the remainder gradually diminishing 

 in length, lllcena, Er., is probably nearly allied to this genus ; 

 but he describes the prothorax as only slightly nodose at the sides. 

 The other characters given by Erich son are very general ; but he 

 compares it to Ancssthetis and Deroplia {Stenidea). Of the second 

 species I have seen only a single example. Both species I owe to 

 Mr. Odewahn. 



Neissa inconspicua. 



N. fusca, sparse albo pilosa ; elytris obscure pallido variis. 



Hab. South Australia (Gawler). 



BroviTi, clothed with more or less erect whitish hairs ; the elytra faintly 

 marked with indistinct palish patches j head and prothorax closely 

 punctured, the lateral spine of the latter very slender even at the base ; 

 scutellum triangular ; elytra subseriate-punctate, obliquely depressed 

 outside the basal crest, the side abruptly bent down, the angle there 

 formed not prominent, towards the apex a short, slightly elevated 

 line ; body beneath, legs, and antennae rufous brown, sparingly pilose. 

 Length 2 lines. 



Neissa nigeesta. 



JV. subdepressa, nigra, pube brevi concolore et piUs dispersis albidis 

 tecta ; antennis scapo, articulis tertio et quarto longioribus. 



Hab. South Australia (Gawler). 



In most of its characters closely agreeing with the preceding, but in size 

 and colour apparently very distinct ; the pubescence is also shorter, 

 and, to the naked eye, is nearly uniformly black ; the scape and third 

 and fourth joints of the antennae are relatively longer, and the legs are
