cimens (two males and one female) before me; the sides of the 

 thorax are also straight posteriorly, instead of rounded as in the 

 former species.

Very simila.r in general appearance to A. foveicollis, Kiist., the 

 thorax less deeply excavated on the middle disk, the outer half of 

 the antennaD black. I only know the male of this species. 



18. AuLACOPHORA Fabricii. Anguste subelongato-ovata, postice 

 paullo ampliata, convexa, flava, nitida, antennis (basi exceptis), pedibus 

 posticis quatuor, pectore abdomineque (hujus apice excepto) nigris ; 

 thorace transversim sulcato, sulco in mare disci medio magis pro- 

 funde excavato ; elytris tenuiter pimctatis. Long. lin. 



Mas. Antennarum articulo basali incrassato, abdominis segmento anali 

 trilobato, lobo intermedio alteris longiore, sat profunde concavo- 

 excavato. 



Fcem. Abdominis segmento anali apice sinuato. 

 Hah. Tonga Islands. 



Antennae filiform, nearly three fourths the length of the body, 

 the basal joint in the male strongly thickened. Thorax nearly 

 twice as broad as long ; sides nearly straight and slightly diverg- 

 ing from the base to beyond the middle, thence rounded and con- 

 verging towards the apex ; disk transversely excavated, the 

 sulcation in the male more broadly and deeply excavated on the 

 middle disk. Elytra narrowly oblong, slightly dilated posteriorly, 

 very finely punctured. 



Separated from A. nigroscutata by the flavous scutellum and by 

 the thoracic sulcation extending entirely across the disk ; the 

 apical abdominal segment in the female is also differently formed. 



19. AuLACOPHORA NIGROSCUTATA. Anguste oblonga, postice paullo 

 ampliata, convexa, flava, nitida, pectore, abdomine scutelloque nigris ; 

 thorace transverso, disci medio transversim excavato, sulco utrinque 

 abbreviato ; elytris tenuiter punctatis. Long. 3 lin. 



Mas. Thoracis sulco profunde impresso ; abdominis segmento anali tri- 

 lobato, lobo intermedio profunde excavato.
