 R. {Loria, 1892-3). In the British and Genoa Museums. 



This and the following species are remarkable for 

 their great size, their dimensions being far larger than 

 those of any other Hybosorinae known. L. dux appears 

 to resemble L. p)apuuSy Lansb. (with L. cdternatus, Mack, 

 and L. stdccdus, Montr., the only non-Australian species at 

 present known). It is extremely smooth and shining, and 

 the elytra are a little attenuated behind, decorated with 

 deeply impressed striae in pairs and entirely devoid of 

 punctures. The front tibiae have only two external teeth 

 in addition to the usual close serration.

 tato, lateribu'! bene arcuatis, angulis anticis productis, subacutis, 

 posticis rotundatis, margine basali leviter sinuato ; elytris sat brevi- 

 bus, post medium latissimis, omnino sat irregulariter striatis, striis 

 antice et latera versus vage punctatis, dorsi interstitiis partim 

 tessellatis, pectore abdomineque crebre striolatis, opacis ; tibiis 

 anticis serratis, dentibus tribus majoribus : 



* .Just before going to press I liave received Herr Felsche's descrip- 

 tion of tliis species, to which I had given another name. By the 

 author's kindness I have been able to examine the type.
