Longicornia Malayana. 125 



that I at first thought it might be a variety of it, the antennae are 

 twelve-jointed ; tlie supplementary joint is not simply an append- 

 age of the eleventh, but in all respects a true and perfect joint. 

 A. caWzona has the distal end of the protibiae densely tufted. In 

 the female of A, Polynesus the antennae are thickened towards the 

 apex. Excluding A. basalis, which cannot be considered a true 

 Agelasta, the genus might be divided into two sections, 1st, those 

 with the third joint of the antennae longer than the scape, and 

 2nd, those in which it is shorter ; but between these there is the 

 Manillan A. transversa, in which they are about equal. This, 

 therefore, seems to be one of those genera in which the com- 

 parative lengths of these joints (which generally afford most reliable 

 characters, and this may also be said of the antennae to a certain 

 extent), are to be considered as only of secondary importance. 



All the members of this genus met with by Mr. Wallace were 

 found on fallen trees, but " fell off and lay as if dead when dis- 

 turbed." A. Newmannl was found " flying above newly fallen 

 timber."

Dark brown, with a sparse greyish pile, the shallow punctures 

 giving it a spotted appearance, a broad band across the middle of the 

 elytra, and the apex, reddish or brownish-red ; prothorax rounded 

 at the sides ; scutellum slightly transverse, rounded behind ; 

 body beneath dark brown, subnitid, side of the metathorax with 

 a greyish pile; legs with a close reddish-brown pile, ends of the 

 tibiae, particularly of the anterior, clothed with long black hairs, 

 tarsi with the first two joints and base of the third black, claws 

 black, the rest white; antennae dark brown, base of the fifth and 

 nearly the whole of the sixth joint reddish.
