from the female of pruinosa in being wider, shining median 

 space on head of different shape, and with small but distinct 

 punctures; and elytral clothing as on its own male, instead of 

 mottled. 



Hab. — Western Australia: Karridale, Geraldton ; New 

 South Wales: Galston, Armidale, Blue Mountains. 



EVANIOCERA PERTHENSIS, Blackb. 



The derm of the elytra of this species varies from a 

 rather dingy piceous-brown to almost flavous, with the suture 

 (narrowly) and sides (narrowly to rather widely) blackish. 

 The length varies from 3 to 6 mm., and the species occurs in 

 South Australia (Karoonda to Peebinga), as well as in Wes- 

 tern Australia. 



A female (it is the only four-eyed female in the Museum) 

 from Lucindale evidently belongs to the species ; it is 

 piceous-black (parts of the appendages and tips of the 

 abdominal segments excepted), almost uniformly clothed with 

 greyish pubescence, and the antennae non-nabellate. 



EVANIOCERA MINUTA, Blackb. 



There were two specimens (sexes) of this species in the 

 Blackburn collection from Northern Queensland, but they 

 differ from the type in being smaller (2|--3 mm.) ; both 

 specimens have the elytra somewhat paler than on the type, 

 and with the suture as well as the outer margins somewhat 

 paler. 



Euctenia sericea, Gerst. 



There are before me eight specimens belonging to two 

 forms — the first, named as sericea, in the Macleay Museum ; 

 the other, also so named, in the Blackburn collection. They 

 are strikingly alike in general appearance, but the differences 

 noted below are quite distinct : — 



Form 1. Form 2. 



Head with a rather wide, shal- Median line commencing some 



low, semidouble, median line distance behind eyes, and con- 



from between eyes to vertex, tinued over vertex (from 



where it vanishes. behind the vertex appears 



bilobed). 



With a short, shining, median Without a shining line in front, 

 line in front (sometimes 

 scarcely traceable). 



Gently depressed between eyes. Gently convex between eyes. 



Prothorax with a shallow dis- Prothorax flat at the position 



cal impression towards base, of the discal impression of 



and with a shallow one on Form 1. 

 each side of base. 



Length, 8-9£ mm. Length, 9-11 mm.
