Bemhidium cillenoides n. sp. 



Note: This species bears some resemblance to Cdlenum

Shape : Head slightly narrower than thorax Thorax cordi- 

 form , short , considerably wider than long , moderately narrowed 

 behind ; sides rather rounded in front , hind angles about 90 ^, 

 sharp. Elytra somewhat broader than thorax, oblong-oval, with 

 slightly rounded sides. 



Sculpture : Frontal furrows single, parallel. Base of thorax 

 on each side with 2 parallel, longitudinal furrows ; the lateral 

 one fine , linear , its extreme side being limited by a fine keel, 

 which continues to tip of basal angle ; the innermost forming an 

 oval depression without punctuation and without well defined 

 limits. Elytra finely, but sharply punctate-striate ; Striae all over 

 distinct and if anything deeper near apex. 



Colour : Head metallic black. Thorax pitchy reddish, some- 

 what shining , with more or less indistinct metallic reflection. 

 Elytra impurely pale yellowish, with a very ill (or indistinctly) 

 defined , brownish M - shaped shadow just behind middle and a 

 similar, transverse shadow at some distance from apex. Antennae 

 and palpi brownish yellow, but darker towards apex. Legs pale 

 clay-yellow.
