 Mallodonfulvipewie, Pascoe^ Trans. Ent, Soc. ser. 2, v. 15. 

 Archetypus jjarandroides, J. Thomson, Essai &c., p. 320. 



A. rufo-brunneus, nitidus, olytris fulvo-testaceis. 



Hau. — Aru; Bouru; Waigiou; Dorey. 



Reddish-brown, shining ; head darker, coarsely punc- 

 tured, the punctures crowded behind the eyes, scattered 

 in front; prothorax with a smooth callosity occupying 

 the whole disc, except at the sides, which are finely and 

 closely punctured; scutellum oblong, rounded at the 

 apex; elytra yellowish-testaceous, nearly smooth, but 

 covered with minute shallow punctures; body beneath 

 luteous-brown, the meso- and meta-sterna covered with 

 long grayish-yellow hairs; legs and antennae reddish- 

 brown. 



Length 12-15 lines ( ? ) ; 22 lines (J"), including the 

 mandibles. 



My typical specimen from Aru has the punctures on 

 the elytra much larger, and by their occasional confluence 

 forming marked irregular impressions, which do not exist 

 in the other examples now before me. 



Zakacin^e. 



Two genera, each comprising a single species, are all 

 that at present constitute this subfamily. They are both 

 Malayan, although only one was detected by Mr. Wallace; 

 the other, Neoprion, is stated to resemble a large-sized 

 Parandra.
