Cestrinus tuberculatus, n. sp. 



Rather widely oval ; opaque brownish-black above and 

 below; antennae, palpi, and tarsi red. 



Head densely rugosely asperate, received rather 

 deeply into the prothorax; epistoma short, obliquely 

 rounded at sides, its suture deeply impressed and 

 straight ; ocular canthus as wide as the eyes, and not at all 

 impinging on their sides ; eyes round and rather prominent ; 

 antennae not, or scarcely, extending to base of prothorax, stout, 

 joint 3 as long as 4-5 combined, 4-8 moniliform, 9 longer than 

 8 and widened at apex, 10 as wide as long, 11 ovate, larger 

 than preceding. Prothorax 2 J x 3 J mm., widest at middle, 

 arcuate-emarginate at apex, slightly bisinuate at base; anterior 

 angles produced and acute, posterior subdentate and acute; 

 sides rather widely rounded and sinuate behind, finely serrated 

 anteriorly, coarsely denticulate-serrate posteriorly ; disc un- 

 even, densely and coarsely rugosely asperate, with very short 

 bristly hairs; its margins a little explanate but not differen- 

 tiated from disc, medial line clearly impressed, and two foveate 

 depressions near centre. Elytra more convex than usual in 

 the genus, wider than prothorax at base; shoulders rather 

 square, prominent and slightly reflexed ; apical declivity some- 

 what steep, sides sinuate towards apex; disc closely and 

 strongly tuberculate, each tubercle bearing a short sub- 

 recumbent hair; each elytron with four equidistant costae, 

 besides a sutural costa, composed of closely-placed larger 

 tubercles; the fourth costa, seen from above, giving a finely- 

 serrated outline to the elytra-. Epipleurae, abdomen, and legs 

 coarsely punctate ; prosternum coarsely vermiculately rugose ; 

 flanks of meso- and metasternum with large round punctures ; 

 posterior intercoxal process widely rounded; prosternum con- 

 vex, its process little produced and simple. Dimensions — 

 7J-8-Jx3j-3| mm. 



Hab. — Western Australia: York (Mr. H. Giles), Harvey 

 (the author). 



Four specimens were sent me some time ago by Mr. Henry 

 Giles, labelled "York, l-X.-'08.," and since taken by myself
