MR. J. S. BALY ON SOME GENERA 



12. AULACOPHORA OlITIERI. 

 Galeruca analis, Oliv. Ent. vi. 



ObloDgo-ovata, convexa, flava, nitida, labro, antennis (basi exceptis), 

 mesosterno, abdominis apice, tibiis tarsisque nigro-piceis aut nigris ; 

 thorace quara longo fere dwplo latiore, transversim sulcato, sulco 

 medio minus fortiter impresso ; elytris tenuiter punctatis, utrisque 

 plaga magna basali, ad suturam abbreviata, altera pone medium, ad 

 marginem plerumque adfixa, apiceque nigris. Long. 3-3^ lin. 



Mas. Antennarum articnlis tertio, quarto quintoque incrassatis ; abdo- 

 minis segmento anali trilobate, lobo interraedio longitudinaliter 

 sulcato. 



Fem. Antennis filiformibus; abdominis segmento anali apice ro- 

 tundato. 



Hah. Australia, Hunter's Eiver, Eockbampton, Paroo Eiver. 



Front impressed immediately above the encarpse with a small 

 fovea; antennae robust, the third, fourth, and fifth joints in the 

 d thickened, the third nearly twice as long as broad, obconic, the 

 fourth and fifth each shorter than the third, laterally dilated, tri- 

 gonate ; antennae in the $ simple, filiform ; the five lower 

 joints in the S , the three or four basal ones in the $ , flavous or 

 fulvous, more or less stained with piceous, the remaining joints 

 in each sex nigro-piceous or black. Thorax nearly twice as 

 broad as long ; sides slightly diverging and slightly sinuate from 

 the base to just beyond the middle, thence rounded and con- 

 verging to the apex ; upper surface remotely and minutely punc- 

 tured, transversely sulcate immediately behind the middle, the 

 sulcatiou rather less deeply impressed on the middle disk. 

 Elytra oblong, slightly dilated posteriorly, convex, minutely 

 punctured, the basilar space obsoletely thickened. Tibiae and 

 tarsi black, the basal portion of the former sometimes flavous. 



This species usually stands in collections as A. analis, Weber ; 

 it is very constant in pattern and coloration, and diff'ers from the 

 author's description of analis in the dark antencae, in the black 

 aj^ices of the elytra, and in the similarly coloured mesosternum. 

 Its locality is also entirely diflerent, all the specimens that I have 

 seen having been brought from Australia ; whereas Weber gives 

 Sumatra as the habitat of his insect. 



13. AuLACOPiioRA OCCIPITALIS. Subclongata, postice paullo am- 

 pliata, conv exa, flava, nitida, oculis, verticis plagis duabus, pectore 

 abdomineque nigris; thorace prope medium transversim sulcato;
