The insect is usually covered with sappy matter concealing the 

 colour and sculpture.

Taken from a Mesembryanthemum on Mokohinau Island by Mr.

Agacalles. 



Nov. gen. 



Rostrum as long as thorax, slightly and gradually expanded 

 apically, a little arched ; its scrobes deep, extending from the 

 middle to the eyes : these latter depressed. Antenna moderate ; 

 scape short, flexuose, thickened towards the end; funiculus 

 7-articulate, the two basal joints elongate; club large, ovate. 

 Thorax oviform, without ocular lobes, but with its apex obtusely 

 projecting over the head, base sub-truncate. Scutellum invisible. 

 Elytra cordiform. Legs long, femora not much inflated but widely 

 excised near the extremity, each with an obvious tooth underneath ; 

 tibia somewhat sinuous^ with distinct apical hooks ; tarsi rather 

 narrow, pilose below, basal joint elongate, second short, third 

 broadest, deeply lobed. Pectoral canal profound, extending half- 

 way through the mesosternum ; metasternum very short, truncate 

 between the coxae. Abdomen elongate, its basal segment twice the 

 length of the metasternum, second shorter, third and fourth very 

 short, fifth inflexed. Epipleura linear. Body rather elongate, con- 

 tracted medially, not crested. 



Whilst exhibiting the characters of Acalles (having the facies of 

 an elongated Acalles hystriculus), it departs therefrom by the dentate 

 thighs. It is quite dissimilar to such forms as Crisius, Tychanus, 

 and Sympedius. 



1746. A. formOSUS, n.s. Elongate, medially narrowed, mode- 

 rately convex ; blackish, tarsi and antennae fulvous, snout rufo- 

 piceous ; clothing variegate, chiefly depressed, hair-like, red scales, 

 some greyish ones often form three small spots on the base of the 

 thorax, and a more or less evident oblique fascia (broadly bordered 

 outside with black) near the hind thigh; there are lateral patches 

 pitchy, and the posterior squamosity is usually fulvous ; there are 

 also numerous dusky, erect, hair-like setae. 



Rostrum striate-punctate, its basal part covered with greyish 

 scales. Antenna implanted behind the middle ; scape much shorter 

 than the funicle, the two basal joints of which are of almost equal 

 length, but the second is much more slender than the first, third 

 and fourth a little longer than broad, the following three sub- 

 quadrate. Thorax widest at the middle, oviform, coarsely punctured. 

 Elytra elongate-cordate, slightly broader at base than the thorax, 

 attenuated behind; coarsely striate-punctate, posterior sculpture 

 less easily seen. Underside blackish, coarsely and closely punctured, 

 bearing slender yellow scales, third and fourth abdominal segments 

 with one row of punctures, fifth clothed with hairs instead of 

 scales.
