I do not know eremitus and waterhousei, but the other? 

 may be tabled as follows : — 



A. Prothorax impunctate along middle (36) ... mormon 

 AA. Prothorax with punctures along middle. 

 B. Each elytron with two rows of isolated 

 tubercles. 

 a. Each elytron with two large tubercles 



at base basalis 



aa. Each elytron with but one large 

 tubercle at base. 

 b. A conspicuous spot of pale clothing 



near each shoulder quadrimaculatus 



}>b. Elytra not maculate luctuosus 



BB. Each elytron with two longitudinal 

 costae.(37) 



C. Prothorax with two small conical 

 tubercles on disc, as well as a large 



one on each side bifasciatus 



CO. Prothorax without conical tubercles 

 on disc. # 

 D. Black spots on elytra all small and 



isolated arachne 



DD. Black spots often conjoined to form 



large irregular blotches senex 



Microtragus luctosus, Shuck. (Morimus). 



M. amycteroides, Pasc. (Stychus of Lacordaire). 

 M. pascoei, Thorns. 



In Lacordaire's Atlas two species are figured on plate 96 

 under the specific name of amycteroides : — 



Stychus amycteroides, Pasc, fig. 4, from Australia, 

 Phantasis amycteroides, Pasc, fig. 5, from Africa; 



but the references to the figures are transposed, as figure 5 



is quite evidently of the Australian beetle, it having but two 



rows of tubercles on each elytron (Pascoe says "tuberculorum 



serielus duabus," and again, "each with two rows of stout 



prominent tubercles"), not at least three, as on the other 



fioure.

The description of Morimus luctuosus agrees well with the 

 specimens before me, and I have no doubt but that it is 

 synonymous with amycteroides, of which it has precedence. 

 It was recorded as from Tasmania by Shuckard, but the 

 locality was queried in Master's Catalogue. I have only seen 



(36) On the variety sticticus of arachne the punctures along 

 the middle of the pronotum are not actually visible, but their 

 positions are indicated through the clothing. 



(37) The costae, owing to their clothing, frequently have an 

 appearance as of being broken up into tubercles, but even when 

 a few are divided off, they are connected with the costae by lower 

 ridges.
