of the Genus Gatasarcus. 35 



Hah. — Champion Bay. 



The elytra of this species are closely covered with scales 

 of a clear ochre-yellow, except a broad abbreviated stripe 

 of pale ashy at the side. The frontal grooves in this and 

 some of the following species are almost obsolete, the 

 middle one only showing itself as a sort of notch directly 

 above the transverse sulcus. 



30. Gatasarcus alhisparsus. 



Moderately ovate, glossy black, with condensed patches 

 of pure white scales ; rostrum with four short stoutish 

 ridges above the transverse sulcus ; eyes oblong, pointed 

 below, the lower border, and the cheeks, white ; prothorax 

 narrowly transverse, two broad irregular grooves on each 

 side, the anterior one at the base filled in with a line of 

 snowy scales, a similar line extending behind it; scutel- 

 lum broadly triangular, depi'essed; elytra seriate-punctate, 

 the punctures large, more or less confluent transversely, 

 the interspaces forming well-marked transverse ridges, 

 which, however, disappear posteriorly, a short line on the 

 suture, patches at the sides, and some of the punctures 

 behind scaly white, the rest of the elytra glabrous, post- 

 humeral spine straight, black, median and posterior pairs 

 glossy reddish, the latter nearly as large and as long again 

 as the former ; body beneath black, with pm-e white scales 

 more or less interrupted, sides of the first abdominal seg- 

 ment marked with a few black granules ; legs reddish, 

 femora with scattered hair-like scales, tibiee and tarsi with 

 dispersed white scales ; antennae slender, ferruginous, 

 nearly without scales, club dark brown. 



Length 4 lines. 



Sab. — Champion Bay. 



A pretty little species, well distinguished by its patches 

 of chalky- white scales, contrasted, especially on the elytra, 

 with the glabrous glossy black. 



31. Gatasarcus carbo. 



Oblong ovate, black, subnitid, with whitish minute 

 scales in the cavities ; head convex in front, without 

 carinas, a short deep groove above the transverse sulcus,
