AULACOPHORA CORNUTA. 213 



ridge and the antennae are of normal construction ; in both 

 sexes the third and fourth joiuts of the latter are nearly 

 equal; amongst the specimens from Sumatra several va- 

 rieties occur in which the legs are either partially or en- 

 tirely fulvous as well as the underside while others agree 

 with the typical form (black underside and legs). A. fla- 

 vipes Jacoby is smaller , the last abdominal segment is 

 fulvous and the antennae in the male are of different con- 

 struction. 



Aulacopliora Q-punctata ?, Oliv. 



All the specimens obtained by Dr. Hagen differ from 

 Olivier's species in having the entire base of the elytra to 

 the extend of their first third black as well as the legs; 

 other specimens have fulvous elytra with a black spot be- 

 low the middle; as it is quite possible that this species is 

 very variable in regard to colour , I have abstained in de- 

 scribing it as new , although it may be possibly distinct 

 from the one described by Olivier since the 10 specimens 

 before me all agree with each other, with the exception 

 of one or two which have the anterior legs fulvous , thus 

 indicating intermediate degrees of colour. 



I am unable to determine with certainty the following 

 species : 



Aulacophora spV 



Black ; antennae flavous ; head and thorax fulvous ; ely- 

 tra black , finely and closely punctured ; anterior legs obs- 

 cure dark fulvous. — Length 4 lines. 



(ƒ. Third joint of the antennae elongate and the longest , 

 the following short and semitriangularly shaped, 

 terminal joint dilated at the middle into a tooth. 



9. Antennae simple. 



This insect does not quite agree with either of the many 

 similarly coloured species described by different authors on 

 account of the structure of the antennae in the male in 

 connection with the black underside and legs.
