Taken from a Mesembryanthemum on Mokohinau Island by Mr.

Agacalles. 



Nov. gen. 



Bostrum 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. AntenyicB 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. Scutelhim invisible. 

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

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

 tihice 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 mesosternuin ; mctasternum 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. Epipleurce 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 Grisius, Tychanus, 

 and Sympedms. 



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

 rately convex ; blackish, tarsi and antennas 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 setse. 



Bostrum striate-punctate, its basal part covered with greyish 

 scales. AntenncB 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 beliind ; 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.
