AND SPECIES OF GALEBUCINiE. 
167 
Antennge filiform, nearly equal to the body in length in the c? , 
the third joint nearly twice as long as the second; pale flavous, 
the two lower joints flavo-testaceous, the two upper ones black. 
Thorax about one third broader than long ; sides obliquely di- 
verging and obsoletely sinuate from the base to the middle, 
thence rounded and converging to the apex, anterior angle pro- 
duced into an obtuse tubercle, the hinder angle slightly produced, 
acute ; disk convex, smooth, impunctate. Elytra convex, very 
minutely punctured ; each elytron in the S with a large ovate, 
deeply excavated fovea, placed on the outer disk immediately below 
the humeral callus and extending nearly to the middle, its entire 
margin strongly thickened. 
I possess five specimens of the above insect collected by 
Mr. Wallace in Celebes: the broader form, together with the 
position of the elytral fovea, will at once separate it from the 
allied species ; the elytral epipleurae are also less abruptly nar- 
rowed below the middle than in the other similarly-coloured 
specific forms. 
The five species described above are usually confounded in 
collections under the name of Ticemorrhoidalis or terminata : the 
structural differences, however, at once separate them. 
The following short Table will assist in distinguishing the 
species described above : — 
1. Thorax impressed in the centre with a transverse fovea. 
foveicollis. 
2. Thorax not transversely sulcate. 
a. Thorax only slightly broader than long . . Cumingii. 
aa. Thorax distinctly broader than long. 
b. Thorax one half broader than long .... hopmorrlioidalis. 
bb. Thorax one third broader than long. 
c. Elytra oblong-ovate terminata. 
cc. Elytra broadly ovate Wallacei. 
6. Monolepta verticalis. Anguste ovata, postice paullo ampliata, 
convexa, nigro-picea, nitida, capite, antennis basi, thorace pedibusque 
anticis pallide flavis, pedibus posticis quatuor piceo- fulvis ; capitis 
vertice fovea rotundata magna impresso ; thorace transverso, convexo, 
lffivi; elytris tenuiter punctatis, utrisque maculis duabus, una infra 
basin, altera prope apicem, flavis, ornatis. Long. 2 lin.
