808 AUSTRALIAN COLEOPTEBA, WITH DESCRIPTIONS OF NEW SPECIES, 



Gnathaphanus Darwini, sp.nov. 



Niger, vix aenescens ; antennis, palpis, pedibusque plus minusve 

 rufescentibus ; prothorace antice minus angustato, angulis posticis 

 rotundato-rectis ; elytrorura interstitiis 3° (duplici serie) 5° et 9° 

 seriatim punctulatis. Long. 3i lines, lat. 1| lines. 



The front of the labrurn, the palpi, and the basal joint of the 

 antennae are brownish testaceous, the remaining joints of the 

 latter being of the same color more or less marked with piceous; 

 the legs are brown. The surface of the head is even behind the 

 clypeal suture except that there is a puncture in a feeble depression 

 on either side in front, and another near the inner margin of each 

 eye. The prothorax is not quite half again as wide as it is long 

 down the middle, its front margin not much narrower than its 

 base ; its sides are moderately rounded, the flattened margin being 

 very narrow in front, but widening considerably hindward ; the 

 dorsal channel is well marked, the arched impi'ession in front fairly 

 defined, the basal impression on either side shallow, but not small; 

 the surface is devoid of punctures, except the setiferous one on 

 either lateral margin. The elytra are rather strongly striated, the 

 abbreviated stria rather long and well-defined ; the interstices 

 are flat ; the 3rd interstice bears four large punctures in its front 

 half and two (far apart) in its hinder half close to its outer edge, 

 and also (in its hinder half) close to its inner edge several similar 

 ones ; the 5th interstice bears six or seven (similar) close to its 

 outer edge, and the 9th a somewhat more numerous series inter- 

 spersed with some smaller punctures. 



The double series of punctures on the 3rd interstice seems to 

 distinguish this species from all its allies. 



Northern Territory of South Australia ; collected by Mr. J. P. 

 Tepper. 



Hypharpax parvus, Chaud. 



I have very little doubt that this is identical with Harpalus 

 [Ili/pharpax) inoruatus, Germ.
