on either side. Elytra broader than the thorax, rather broadly 

 dilated behind the middle, convex, rather strongly excavated 

 below the basilar space, minutely punctured, the puncturing on 

 the hinder disk nearly obsolete. 



4, AuLACOPHORA PYGiDiALis. Oblongo-ovata, posticc ampllata, con- 

 vexa, flava, nitida ; abdominis segmento ultimo plus minusve, 

 pygidio, pedibus posticis fere totis, tarsis anticis quatuor, tibiis in- 

 termediis (basi exceptis), labro, antennis (basi exceptis) elytrisque 

 nigris ; his infra basin transversim excavatis, minute punctatis, fascia 

 lata prope medium, interdum interrupta aut abbreviata, flavo-fulva ; 

 thorace vix pone medium transversim sulcato. Long. 3-3^ lin. 



Var. A. Abdominis disco plus minusve nigro-piceo tincto. 



3Ias. Abdominis segmento anali trilobate, lobo intermedio oblongo, 



profunde concave. 

 Form. Abdominis segmento anali apice obtuso, integro. 



Sal. Aru Islands ; New Guinea, Dorey ; Cerara ; Ke Islands 

 ( Wallace) . 



Antennae slender, filiform, black, more or less piceo-fulvous at 

 the base. Thorax more than half as broad again as long ; sides 

 obliquely diverging from the base to beyond the middle, sub- 

 angulate anteriorly ; disk transversely sulcate just behind the 

 middle. Elytra very finely punctured. 



Closely allied to A. albofasciata, smaller and the male broader 

 than that species, its eyes less prominent ; the coloration of the 

 legs varies greatly in degree.
