longiori dimidia parte latiori, postice quam antice vix latiori, 

 margine antico parum concavo, lateribiis sat sequaliter rotundatis, 

 angulis posticis rotundato-obtusis, basi media leviter rotundatim 

 emarginata, striola basali externa vix distincta; elytris basi externa 

 nullo modo dentatis, subtiliter striatis, interstitiis planis, interstitio 

 3° tripunctulato. [Long. 3?, lat. li lines. 



The only species known to me (of the genus) which has the 

 length of the elytra down the suture not at all greater (by measure- 

 ment) than twice their width across the base. The prothorax 

 scarcely (by measurement the base is 5 again as wide as the front) 

 narrower across the front than across the base is also a good 

 character, nor have I seen any other species having the prothorax 

 as much as half again as wide as long. There is a very distinct 

 transverse strip marked more or less distinctly with longitudinal 

 scratches, and abruptly depressed below the general plane of the 

 surface, running along the base of the prothorax from one to the 

 other of the inner longitudinal fovese. The external basal fovea 

 on either side close to the hind angle of the prothorax is very 

 feeble and from some points of view seems to be quite non-existent. 

 The large setigerous puncture near the hind angle of the prothorax 

 is (as usual in the genus) very distinct and well within the angle. 

 The concavity of outline on the base of the prothorax is very 

 clearly confined to the middle part of the base. The abbreviated 

 stria close to the scutellum is exceptionally short. The transverse 

 undulations on the prothorax mentioned by Castelnau are variable 

 in intensity but never very noticeable without close examination. 

 The episterna of the metathorax are wider than in the allied 

 species. 



Extremely abundant in S. Australia. I have not seen it further 

 west than Yorke's Peninsula. 



N.B. — I think there is scarcely any doubt that this insect is 

 identical with S. curtulus, Chaud., and also with S. (Harpalus) 

 brunneus, Cast. It seems to differ from S. fovei2)en7iis, Macl., and 

 S. nitidipennis, Macl., by its short scutellar stria, from aS'. oodiformis 

 by the feebler striation of its elytra, and from most of the other
