MU. J. S. BA.LY ON SOME SPECIES OP GALERUCIX.®. 
cimens (two males and one female) before me ; tbe sides of the 
thorax are also straight posteriorly, instead of rounded as in the 
former species. 
17. Aulacophora abdominalis, Fair. Spec. Ins. i. p. 151. 
Oblonga, pustice paullo ampliata, convexa, flava, nitida, antennis ex- 
trorsum, pectore abdomineque (ano excepto ) nigris ; tborace transversim 
sulcato, sulci medio magis profunde impresso. Long. 3| lin. 
Mas. Abdominis segmenti analis lobo intermedio oblongo, profunde 
longitudinaliter concavo. 
Sab. Islands of the Pacific Ocean {Fair.) ; Western Australia 
(my collection). 
Very similar in general appearance to A. foveicollis, Kiist., the 
thorax less deeply excavated on the middle disk, the outer half of 
tlie antennae 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 ; 
tborace transversim sulcato, sulco in mare disci medio magis pro- 
funde excavato ; elytris tenuiter punctatis. Long. 3-31 lin. 
Mas. Antennarum articulo basali inerassato, 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. Auguste oblonga, postice paullo 
ampliata, convexa, flava, nitida, pectore, abdomine scutelloque nigris ; 
thorace transverso, disci medio transversim excavato, sulco utriuque 
abbreviato ; elytris tenuiter punctatis. Long. 3 lin. 
Mas. Thoracis sulco profunde impresso ; abdominis segmento anali tri- 
lobato, lobo intermedio profunde excavato.
