depressed granules, elongate in middle, more rounded towards 

 sides. Sides granulate. Elytra (11 x 6 mm.) gently rounded 

 on sides, apex moderately strongly rounded, base gently 

 arcuate, humeral angles rather feebly out-turned, noduli- 

 form; disc with rows of small punctures obscured by the 

 clothing, subtended by setae but no definite granules between 

 the punctures; interstices broad and flat where tubercles are 

 wanting, second with two or three subconical tubercles, 

 spaced out between middle and apex, third with a more con- 

 tinuous row of elongate rather large tubercles about ten in 

 number, more spaced out and subconical posteriorly, fourth 

 without tubercles, fifth with a row more closely placed, rather 

 smaller and more rounded about fourteen in number, sixth 

 with a similar row of about eleven. Sides with rather pro- 

 nounced somewhat tortuous tubercles. Fifth ventral seg- 

 ment with a narrow median channel not very deep, bordered 

 on each side behind middle by a triangularly raised ridge 

 or tubercle. Anterior femora not ridged beneath, inter- 

 mediate tibiae with a deep subapical notch. 



9 . Similar but larger and more ovate, with the apex 

 decidedly produced and obtusely mucronate; beneath convex, 

 fifth segment with median channel not bounded by tubercles; 

 intermediate tibiae with much feebler notch. 



Dim. — d, 6x6 mm. ; 9 > 20 x 8 mm. 



Hah . — South Australia : Port Lincoln (Macleay 

 Museum, South Australian Museum). 



All the specimens, with the exception of a pair in the 

 Museum collection labelled Northern Territory (probably 

 an erroneous locality), are from the Port Lincoln dis- 

 trict, where the species appears to be common. The 

 series shows great variation both in the prothoracic 

 and elytral sculpture, in some specimens the prothoracic 

 granules are much smaller, more elongate, and showing a 

 distinct tendency to become obsolete in the middle; the 

 tubercles on the elytra are often variable, in particular those 

 on the more lateral interstices. Some specimens show a 

 decided approach to S. regularis, and it is questionable 

 whether that species should not be regarded as an extreme 

 variation of S. neglectus. Though in most Australian col- 

 lections the species appears to have been overlooked by pre- 

 vious describers.
