Lioderma patulum, sp. n. 



Lato-ovatum, subdepressum, nifi;rum, nitidum ; fronte plana absque 

 striolis, mento loiigitudiualiter canaliculate antice utriiiquo 

 minute tubercnlato ; pronoto lateiibus parce punctato, stria 

 margiuali basi multum abbreviata et ad angulos subfoveolata ; 

 elytris niargine intlexo lajvi, striis subhunaerali lata profunde 

 excavata, 1 dorsali brcvi, 2 integra basi iucurvata ; propygidio 

 circuni parce punctulato ; pygidio leviter punctulato ; prosterno 

 modice lato ; tibiis anticis -i-dentatis. 



L. 9 mill, (absque mandibulis). 



This species is very similar to L. latum, Mars,, but it 

 differs by being more oval, by the canaliculatiou o£ the 

 mentuin, ou the anterior edge of which are two small tubercles, 

 by the shorter mandibles, by the thoracic stria being short- 

 ened behind tlie middle (not at the base only), and by the 

 stria terminating at the anterior angle, not close to the eyes, 

 where it widens out into a small and shallow fovea. The 

 punctuation of the piopygidiuni is also finer. L. patuluni 

 particuUirly agrees with P. latum in the second dorsal stria 

 being markedly incurved at the base, by the prosternum being 

 broad, and in having the mentuni of an exceptional structure. 

 As regards the width of tiie prosternum, both species agree 

 with those of Hololepta, but Marseul placed latum in Lioderma, 

 and it is known that these genera are not at present well 

 defined. The pygidium of L. latum is finely punctulate, not 

 smooth, as stated by Marseul in his Monograph, p. 215.
