neiD genera and species of Tenehrionidce. 273 



and slightly sinuous, the 2 outer ones more or less broken 

 up into irregularly-formed tubercles ; the elevated sutural 

 lines are stronger than in the $ , crenulated, and become, 

 at the scutellar depression, quadrifurcate ; there is also an 

 irregular row of tubercles between each costa ; intervals 

 broad, slightly concave, indistinctly rugose, distinctly 

 punctate, and with a few scattered small tubercles : be- 

 neath, the punctuation &c. is the same in character but 

 (except on the abdomen) feebler than in the $ ; the pro- 

 sternal process is more compressed, and consequently more 

 pointed, behind. 



Hah. — Champion Bay, West Australia. A single 

 example of each sex captured by Mr. Duboulay, to whom 

 I dedicate the species. 



S. Howitti, n. sp. 



^. Long. 5i lin. ; elytra lat. 4 lin. — Oval, black, a 

 little shining on the elytra; legs, palpi, antenna and 

 labrum rufescent ; much shorter and broader than ^ Du- 

 houlayi: mentum slightly angularly notched in the middle 

 at apex ; head rather strongly reticulately rugose ; pro- 

 thorax widest behind the middle, sides rounded (not sub- 

 angulate), base bisinuate, fore-angles narrowly rounded, 

 hind angles acute, disc slightly depressed in the middle, 

 rugosely tuberculate — more finely and confusedly so than 

 in Duhoulayi, the foliaceous margins more strongly reti- 

 culately-rugose than in the preceding : elytra amjjle, de- 

 pressed, much wider than the prothorax, very briefly oval 

 or subrotundate, the apex a little produced, shoulders 

 broadly (not subangularly) rounded, sides distinctly 

 margined throughout, broadest — and reflexed— at and 

 behind the shoulders ; reticulately and rather strongly 

 rugose and punctured, each with four more or less strongly 

 interrupted costfe (which are indistinctly united behind 

 near the apex), the two inner posteriorly, and the two outer 

 entirely, formed by detached elongate or conical tubercles : 

 intervals each with a row of variously-sized tubercles, 

 those on the first—or juxta-sutural — being very elongate, 

 extending to the base and appearing as a twin costa to 

 the inner dorsal one ; the elevated sutural line is crenu- 

 lated at the outer side and becomes confused towards the 

 base, at the scutellar depression, with the reticulate ru- 

 gosities common to the whole of the intervals of the elytra : 

 underside and mentum rather coarsely, but not closely.
