MR. J. 8. BALY ON SOME 8PECIE3 OF GALEBUCIN^. 15 



Fcem. Abdominis segmento anali apice rotundato, medio processu ob- 



longo retrorsura product© armato ; pygidio apice emarginato. 

 Hah. Gilolo ; Amboyna {Wallace). 



Antennae filiform. Thorax nearly twice as broad as loDg ; sides 

 parallel from the base to beyond the middle ; disk convex, deeply 

 impressed with a large transverse excavation, which terminates on 

 either side some distance before reaching the lateral margin ; this 

 excavation is less deeply impressed in the female ; in this sex on 

 either side, between the excavation and the lateral border, is a 

 small fovea. Elytra oblong, dilated posteriorly, convex,, finely 

 and rather closely punctured. 



20. AuLACOPHORA Wallacii. Subelongato-ovata, postice ampliata, 

 convexa, flava, nitida, pectore abdomineque nigris, scutello femoribus- 

 que posticis quatuor nigro-piceis ; thorace transversim sulcato ; ely- 

 tris subnitidis, minute punctatis. Long. 4 lin. 



Mas. Thoracis sulco medio profunde excavato ; antennis filiformibus, 

 articulo primo sat valde incrassato ; abdominis segmento anali tri- 

 lobato, lobo intermedio oblongo, profunde excavato. 



F(Bm. Abdominis segmento anali apice emarginato, incisura transverso- 

 quadrata, basi angulato-producta. 



Hah. Timor {Wallace). 



Antennae filiform, about four fifths the length of the body, 

 basal joint strongly thickened in the male; anterior half of 

 labrum nigro-piceous. Thorax nearly twice as broad as long; 

 sides more or less distinctly sinuate and slightly diverging from 

 the base to beyond the middle, thence obliquely rounded towards 

 the apex ; upper surface finely but distinctly punctured on the 

 sides, impressed across the middle with a nearly straight trans- 

 verse sulcation, which is of nearly equal depth for its whole course 

 in the female, but which is much broader and more deeply exca- 

 vated on the middle disk in the male. Elytra subnitidous, not 

 distinctly excavated below the basilar space, minutely punctured. 



This insect in coloration closely resembles A. siinilis, but 

 the four posterior thighs alone are nigro-piceous, the middle disk 

 of the thorax is more deeply excavated in the male, and the 

 emargination at the apex of the abdomen in the female is of an 

 entirely different form. I only know three specimens, two males 

 and one female, all from Timor.
