 Blackburn's 2445 and 4687). 



The posterior angles of the basal segment of abdomen appear as 

 if the punctures there had been drawn out into short deep sulci; 

 close to them the punctures are larger and sparser than in the 

 middle. The patches of white (or whitish) scales on the prothorax 

 and elytra are very variable in size and extent; on the prothorax 

 towards apex they appear as feeble lines, two, four or five in 

 number, sometimes like chains of spots, on the elytra there are 

 usually white scales on the suture behind the scutellum, a spot on 

 each side at basal third, a transverse chain of spots just below 

 summit of posterior declivity and another chain near apex; on the 

 head the scales are sooty, but between eyes and on base of rostrum 

 they are white; on several specimens, however, the whole of the 

 scales in the head and most of those on the rostrum are sooty. On 

 a small specimen from Port Darwin (in the Macleay Museum) the 

 whole of the apex and sides (except for a few spots) of prothorax 

 are clothed with white scales. On a specimen from Endeavour Pdver 

 the white scales are very distinct between eyes and on rostrum ; 

 almost entirely absent on prothorax, very distinct behind scutellum, 

 from which a very distinct fascia opens out at head third, there is 

 also a very distinct fascia just below summit of posterior declivity 

 and another close to apex. These three fascite are very well defined, 

 and it is evidently remains of them that are visible on the other 

 specimens. 



470. Euthyrrhinus spinipennis Waterh. (Chcetectetorus spinipennis 



Waterh., E. navicular is Pasc). 



Specimens of this species are in the Museum without exact 

 locality; but it appears to be confined to Western Australia. 

 M. Duboulay informed M. Pascoe that he found specimens 

 on Eucalypti. When in Western Australia I never took it at large, 

 but reared numerous specimens from the wood of a species of 

 Bank si a. 



Pascoe (Trans. Ent. Soc, 1870, p. 476) says aChcetecteromis spini 

 pennisis unknown to me » (the type has disappeared from M. Water- 

 house's collection). Personnally 1 have no doubt, whatever, but 

 that Pascoe's description of navicularis, and Waterhouse's of 

 spinipennis, were drawn up from specimens of the same species. 

 Both entomologists leave no doubt as to the species they described.
