DlPLOCOTES FOVEICOLLIS, Oil. 



Mr. Clark has taken four specimens of this species, about 

 the Swan River, associated with the preceding species. Two 

 of them have the elytra considerably darker than in Victorian 

 specimens. 



TENEBRIONIDAE. 



Alphitophagus bifasciatus, Say. 

 A. pictus, Menetr. 

 A. populi, Redt. 

 A. quadripustulatus, Steph. 



. This species has been seen in countless thousands in wheat 

 stacks at North Geelong, although it has apparently not been 

 previously recorded from Australia. For references, etc., see 

 Junk, Col., Cat., Pars. 28, p. 382; where it is recorded as 

 from Europe and North America ; but it is probably almost 

 world-wide in distribution. 



Latheticus oryzae, Waterh. 



This species has been taken at wheat stacks in New South 

 Wales (Barellan and Enfield) ; it does not appear to have 

 been previously recorded as Australia. < For references see 

 Junk, I.e., p. 393.
