BY ARTHUR M. LEA. 485 



Head distinctly quadri-impressed. Rostrum long and thin 

 (stouter in <J than in $) ; densely punctate at sides of base in g 

 (sparsely in £). Scape inserted nearer apex than base of ros- 

 trum in (J, vice versa in 9. Prothorax without tubercular 

 elevations. Elytra with two or three, irregular, transverse series 

 of very large punctures or foveas on basal fourth, elsewhere with 

 feeble series of punctures, which are entirely concealed; each side 

 of suture at base with from one to four, small, shining granules. 

 Mesosternal receptacle narrowed posteriorly, but open throughout. 

 Wings absent. Length, 4 J-6| mm. 



Hab. — Queensland — New South Wales: Tweed and Richmond 

 Rivers. 



In the "big scrub" country, specimens of this species may be 

 obtained on almost every log and stump. The small, sutural 

 granules are variable in numbers and position on different speci- 

 mens, and even on the different elytra; occasionally all are absent. 



This species was labelled as 0. araneus in the Macleay Museum, 

 but since Pascoe described the elytra as " impunctatis ," I thought 

 it possible that some error in numbering had been made, and that 

 the species was really not 0. araneus. But on applying to the 

 British Museum for information, Mr. C. J. Gahan wrote, "The 

 type has some large punctures on disc close to base, and some 

 rather smaller ones at the sides, extending back a short distance 

 from the base. The punctures on the disc are very distinct on a 

 second specimen associated with the type." 



Mr. Arrow sent a co-type of 0. odiosus for examination; it is 

 simply a small specimen of 0. araneus. 



The species differs from the preceding one in being considerably 

 wider, legs longer, tibiae thinner, rostrum shorter, elytra non- 

 tuberculate, etc., besides in the length of metasternum, and absence 

 of wings.
