of the Genus Catasarcus. 19 



carinaB arched in the middle, the spaces between the 

 caringe, especially on the head, covered with pale yellow- 

 ish-gray scales; prothorax apparently glabrous, but 

 uuder a lens, a few minute obliquely placed hairs are 

 visible, above finely and irregularly granulate, its length 

 more than half its breadth at the base ; scutellum minute, 

 glabrous ; elytra sulcate-punctate, the punctures approxi- 

 mate, well-marked, the intervals forming regular tuber- 

 culate elevations, entirely glabrous, except a narrow line 

 of pale yellowish-gi'ay scales along the suture; body 

 beneath, black with small scattered scales, here and there 

 a little more condensed ; legs bright brownish-red, a 

 few fine hairs at the ends of the tibiae, and on the 

 tarsi ; antennae dark ferruginous^ the funicle moderately 

 elongate. 



Length 5 lines. 



Hah. — Western Australia (Perth) . 



This is a nearly glabrous species, on the upper part at 

 least, except the narrow line along the suture, and with 

 the front of the head perfectly flat; in G. hilineatus, the 

 front rises towards the central groove on each side. 



■ 3. Catasarcus opimus. 



Very broadly oval, dark brown or black, covered with 

 pale yellow or yellowish-gray scales; head distantly, 

 almost obsoletely, punctured above, a narrow longitudinal 

 triangular elevation between the eyes, terminating below 

 in a short groove, the groove near the eye on each side 

 as well as the two rostral ones broader than usual; eyes 

 narrow, very decidedly pointed below; prothorax small, 

 short, deeply emarginate at the apex, finely and trans- 

 versely tuberculate above; scutellum small, triangular; 

 elytra rather lightly seriate-punctate, the intervals broad, 

 finely and irregularly tuberculate, the punctures round, 

 shallow, filled up with scales nearly to the level of the 

 surrounding parts, and closely approximate in the longi- 

 tudinal direction; beneath more or less scaly, the first 

 two abdominal segments finely granulate ; legs reddish, 

 or reddish-ferruginous, with minute dispersed scales, 

 knees black, tarsi brown ; antennge slender, all the joints 

 of the funicle elongate, the second only a little shorter 

 than the first.
