and tubercular posteriorly and laterally, intervals between 

 rows not definitely striate nor foveate ; sides obsoletely seriate- 

 granulate. Beneath rather strongly convex ; apical ventral 

 segment with a short transverse linear impression subtended 

 posteriorly by a small obtuse tubercle. Dimensions : 24 x 10 

 mm. 



Labels: 1, 2, 3, Latreille ; 4, 5, Phalidura [struck out] 

 verrucosa d'Urville, h. in Nova Hollandia, D. d'Urville; 6. 



Type, (J T. tuberculatus Boisd. Black, opaque, granules 

 shining ; a few scales in intervals between granules above, 

 a median vitta of light scales branching into two along the 

 internal rostral ridges. 



Head and rostrum as in 2- Prothorax (6x7 mm.) with 

 more definite collar-constriction ; more irregularly and 

 coarsely granulate, roughly in four groups, one lateral and 

 one along median line on each side, leaving three intervals 

 (interstitiis tribus levibus). Elytra (15 x 9 mm.) rather 

 narrower than in ^ , apex mucronate, base feebly emarginate, 

 humeral angles tuberculiform ; disc convex, feebly depressed 

 along suture, granules and tubercles rather coarser and fewer 

 in number than in q • Beneath concave ; third and fourth 

 ventral segments together equal to apical, fifth shallowly 

 excavate, a deep transverse fossa present in posterior half, 

 two small tubercles situated one on each side of the exca- 

 vation. Dimensions: 23 x 9 mm. 



Labels: 1, Nouv. Hollande ; 2, Coll. Dejean, Coll. Roelofs ; 

 3, tuberculatus d'Urville. 



Both of these species should, I think, be referred to 

 Talaurinus verrucosus Guerin. I have described both in 

 some detail, as they vary rather considerably in the pro- 

 thoracic and elytral granulation ; this variation is, however, 

 not sexual ; the apical ventral segment does, on the other 

 hand, shew sexual variation. The following table shows the 

 variation in the number of the granules in each elytral 

 row: —
