with very fine, distinct, slightly flexuous lines; these are 

 caused by brown adpressed setul«, which follow each other 

 nearly in two rows between the punctures.

Ilab. Lizard Island. 



The arrangement of the larger scales on the elytra gives 

 their surface a woven appearance, the tip of one scale nearly 

 toucliing the base of the two behind it and on each side, and 

 forming what may be called the web or warp, while the woof 

 consists of the ordinary scales between. The front of the head 

 is apparently denuded, but under a strong lens it is seen to 

 be clothed with small scales of the same colour as the parts 

 they cover. 



Enchymus. 



Rostrum modice elongatum, apicem versus crassius, supra tricari- 

 natum ; scrobes terminales, arcuatae, ad latera rostri desinentes. 

 Funiculus articulis obconicis. Protliorax subtransversns, lobis 

 ocnlaribus fere obsoletis. Scutellum parvum, distinctum. Elytra 

 cordato-ovata, humeris prominulis. Femora iucrassata; tibice 

 posticae apice apertse ; tarsi articulo tertio fortiter bilobo, ultimo 

 elongato ; unguiculi divaricati. 



The open corbels of the posterior tibiae, and the arched 

 scrobe terminating at some distance from the eye on the side 

 of the rostrum, are the two principal characters of this genus. 

 The sculpture of the species described below is somewhat 

 peculiar ; the elytra are marked with several dark spots, which, 

 under a lens, are seen to be caused by punctures much larger 

 than the others, and which are irregularly impressed in the 

 striae.
