ME. J. S. BALY ON SOME SPECIES OE GALERUCINiE. 
antennis, pedibus totis, pygidio elytrisque nigris ; thorace laevi, sat 
profunde transversim sulcato ; elytris infra basin transversim de- 
pressis, tenuissime punctatis. Long. 3^-5 lin. 
Var. A. Femoribus pygidioque rufo-fulvis. 
Mas. Abdominis segmento anali trilobato, lobo intermedio transverso- 
quadrato, angulis anticis rectangulis, apice truncato, disco longi- 
tudinaliter sulcato. 
Fcem. Abdominis segmento anali late sed leviter angulato-emarginato. 
Hob. New Guinea, Horey; Amboina (Wallace). 
Antennae slender, filiform, nearly equal to the body in length 
iu either sex, black, the two to four lower joints usually rufo- 
piceous ; labrum and mouth nigro-piceous. Thorax transverse ; 
sides nearly straight and parallel from the base to beyond the 
middle, thence rounded and converging towards the apex, 
anterior angle obtuse ; disk smooth, impunctate, discoidal 
groove nearly straight, more deeply impressed on either side 
the median line. Elytra dilated posteriorly, convex, transversely 
excavated below the basilar space, very minutely punctured. 
The dark antennae, equally long in both sexes, will separate 
this species from others with similarly coloured elytra. It is 
with some doubt that I have placed var. A under the same 
specific head; it agrees, however, entirely in structural cha- 
racters. 
3. Aulacophora albofasciata. Anguste ovata, postice paullo 
ampliata, convexa, fulvo-nitida, antennis, ore, tibiis tarsisque nigro- 
piceis aut fuscis ; thorace tx-ansverso, disco transversim sulcato ; elytris 
convexis, infx-a basin prope suturam leviter transversim excavatis, 
nigris, utrisque fascia obliqua prope medium communi, ad marginem 
abbreviata, albida. Long. 4-5 lin. 
Var. A, cf . Elytrorum fascia albida fere obsoleta. 
Mas. Abdominis segmenti analis lobo intermedio oblongo, profunde 
concavo. 
Fcem. Abdominis segmento ultimo latq obtuso. 
Hab. New Guinea, Dorey {Wallace). 
Head scarcely longer than broad, trigonate. Antennae 
slender, equal to the body in length in both sexes ; the four of 
five lower joints sometimes obscure fulvous ; eyes in the male 
large, prominent. Thorax nearly twice as broad as long; sides 
slightly diverging or nearly parallel from the base to beyond the 
middle, thence obliquely converging to the anterior angle; disk 
transversely sulcate, the sulcation rather more deeply impressed
