stices of the elytra. I have two examples sent to me by Mr. Masters 

 which may possibly represent a closely allied distinct species, as 

 they .are of even broader and more robust form than the type, 

 with the pale spots on the elytra evidently (though only slightly) 

 raised, but their colours and markings agree so exactly with those 

 of the type that I am disposed to think them merely fine and 

 highly developed examples of the one species.

A. lindensis, sp. nov. Mas. Brevis ; latus ; sat convexus ; rufo- 

 brunneus, sternis et antennarum clava piceis ; pube cinerea 

 in partibus vestitus sicut partes baud pubescentes ut notulse 

 obscuraa apparent (harum prsesertim manifesta est in elytris 

 notula magna basalis subsuturalis, — in exemplis nonnullis 

 cum alterius elytri notula conjuncta); antennis prothoracis 

 basin vix attingentibus, articulo 9° quam 10 us sesquilongiori, 

 clava sat gracili ; prothorace sat transverso, confertim sub- 

 tilius granulato - punctulato, antice angustato, lateribus 

 modice arcuatis, angulis postieis (superne visis) sat rectis ; 

 v elytris striato - punctulatis, interstitiis confertim aspere 

 punctulatis ; femoribus subtus (anticorum parte media acute 

 trispinosa) mox ante apicem profunde emarginato, apice

This species is at once separable from the preceding two 

 (bicristatus and Koebelei) and from fasciculatus, De G-., by the 

 peculiar structure of the front femora of its male. The markings 

 (resulting from the presence of spaces on which the ashy pube- 

 scence is wanting) form a vague mottling on the prothorax and 

 elytra, of which the most conspicuous feature is a rather large 

 basal elytral spot close to the scutellum on either side (the two 

 spots united in some examples). This basal elytral spot appears 

 very dark and well defined when the insect is looked at obliquely 

 from in front, but is much less noticeable when looked at from 

 behind. The other parts of the elytra devoid of ashy pubescence 

 appear as small spots running into indistinct oblique fasciae, — in 

 some examples their fascia-like disposition scarcely discernible. 



Although I have taken about seven specimens of this insect, 

 they are all males. 



S. Australia (Eyre's Peninsula). 



A. sambucinus, Boisd. Praecedenti (A. lindensi) afnnis ; minus 

 brevis ; antennarum clava magis robusta ; elytris ad basin 

 haud vel vix perspicue plaga obscura notatis ; tarsorum 

 anticorum articulo basali sat majori.
