Descriptions of New Genera and Species.

 (Communicated by Mr. A. M. Lea.) 



[Read August 8, 1912.] 



[Just prior to his death Mr. Blackburn had completed 

 descriptions of numerous species of the genus Lepidota; he had 

 also described a few species of other genera, and was preparing 

 to systematically investigate the Dynastides. As his writings are 

 quite ready for publication, and the types of the new species are 

 marked as such, it appears very desirable that these, his final 

 descriptions and notes, should be published. — A. M. Lea.] 



LAMELLICORNES. 



LIPAROCHRUS. 



L. hackeri, sp. nov. Minus nitidus; piceo-niger, sat con- 

 vexus ; ovatus ; supra glaber ; clypeo subtiliter punctu- 

 lato, antice late truncato, lateribus ante oculos subito 

 fortiter dilatatis ; prothorace fortiter transverso, antror- 

 sum fortiter angustato, supra in disco sat laevi latera 

 versus subtiliter subobsolete punctulato, lateribus leviter 

 arcuatis, angulis anticis acutis posticis rotundato-obtusis, 

 basi subtiliter marginata; elytris subtilius geminatim 

 striatis, striis subtiliter punctulatis, interstitiis planis 

 sparsim subtilissime punctulatis; tibiis anticis extus 

 bidentatis. Long., 6 1. • lat., 3J 1. 



Its larger size distinguishes this species from all its allies 

 known to me. In my tabulation of characters of the known 

 Australian Liparochri (Trans. Roy. Soc, S.A., 1905, p. 271) 

 it falls beside L. sculptilis, Westw., from which it differs by, 

 inter alia multa, its dorsal surface almost without punctura- 

 tion, the elytral interstices (the alternate ones very wide) 

 quite flat, the much stronger crenulation of the external 

 margin of its front tibiae, its much longer tarsi. 



L. hackeri is probably nearer to some Liparochri described 

 from New Guinea than to any previously known as Aus- 

 tralian. From the descriptions of these it differs, inter alia, 

 as follows: — From L. dux, Arrow, by the very distinct punc- 

 turation of its elytral striae; from L. ingens, Felsche, by the 

 smooth non-tessellated interstices of its elytral striae ; from 

 L. papnus, Lansb., by its dark antennae (the flabellum, of 

 paler colour, excepted) and quite evidently punctulate
