SECOND SUPPLEMENT TO THE "REVISION OF THE 

 CrCINDELID^ OF AUSTRALIA." 



By Thomas G. Sloane. 



Genus Megacephala. 



Megacephala bostocki Castelnau. 



Attention may be directed to tlie fact that Dr. Walther Horn 

 has recently authoritatively published the synonymy of M. 

 excisilatera Sloane, with M. bostocki Castelnau, after inspection 

 of the type of Castelnau's species."^ 



Megacephala hopei Castelnau. 



This species has been confused with J/, scapuIai-isMac]., (which 

 is considered by Dr. W. Horn to be a colour-variety of M. aus- 

 tralasice Hope) but is quite distinct. It differs from M. scapularis 

 Macl., by the basal part of pronotum, including the impressions 

 on both sides, being smooth (not tuberculate or rugulose); elj-tra 

 punctate, as usual in the genus (not in wavy lines as in M. 

 australasice); puncturation of basal part stronger, ifcc. The 

 yellow margin is broad at the apex and on the posterior part of 

 the sides, but becomes narrow anteriorly, and does not reach the 

 shoulder, t 



I am indebted to Dr. Walther Hall, of Berlin, for a specimen 

 ticketed as " M. hopei Cast., see. iypus; Nickol Bay." I have not 

 seen it in any Australian collection; and I have placed it in the 

 Macleay Museum for reference. 



The position of M. hopei in the genus is next to M. aiistralasice 

 Hope. 



* Deutsche Ent. Zeit. 1909, p. 164. 

 t Dr. W. Horn has given figures of the elytral pattern of M. hopei and 

 M. scapidaris in Wytsman's " Genera Insectorum " 8'2a Fascicule, Subfam. 

 Cicindelince, p. 29.
