148 THE AMYCTERIO.E OF THK " VOY. DE l'aSTROLABE," 



humeral subcostate, less prominent ; fourth and fifth lateral, 

 close together, almost obsoletely granulate. Sides with 

 interstices obsoletely granulate. Beneath convex ; interme- 

 diate ventral segments large, fifth with a small rectangular 

 impression at apex. JJit/iensioits : 20 x 8 mm. 



Labels: 1, 2, 3, costatus d'Urville; 4, 5, Phalidura [struck 

 out] costata, d'Urville, h. in Nova Hollandia, D. Lesson; 6, 

 Type T. costatus. 



I have compared the three types together, and can find no 

 reason for separating them. The Amycterus Kirhyi of Guerin 

 and Boisduval is not this species, but belongs to the genus 

 Sclerorhinus and probably to *S'. sub costatus, Macl. 



Talaurinus verrucosus Guerin. 



Guerin, Voy. Coquille, ii. (2), p. 121 ; .4. verrucosus Boisd., 

 I.e., p.372 ; .4. tuberculatus Boisd., I.e. p. 372. 



Type, Tahiuriiius verrucosu.<; Boisd., 9 — Elongate-elliptical, 

 robust. Black, without clothing above, a few light-coloured 

 scales in the centre below. 



Head convex, forehead concave between the external ros- 

 tral ridges. Rostrum short, at apex as wide as head, deeply 

 excavate ; external ridges convex in profile, continued on to 

 forehead, constricted at point of junction ; internal ridges 

 obsolete ; lateral basal sulci small, deep : median area de- 

 pressed throughout. Scrobes curved, with posterior sinu- 

 osity. Eyes small, rounded. First and second funicular 

 joints subequal ; club short. Prothorax (6x7 mm.) widest 

 in front of middle, obtusely angulate ; apical margin with a 

 slight postocular sinuosity ; collar-constriction present, me- 

 dian line traceable at base ; rather coarsely granulate, 

 granules irregular in size and arrangement, more bunched 

 together at angles ; sides sparingly granulate below angles. 

 Elytra (16 x 10 mm.) regularly rounded on sides : apex 

 obtusely rounded, mucronate ; base truncate, humeral angles 

 prominent, tuberculiform ; disc convex, with seven irregular 

 rows of projections, granular towards base, becoming conical
