Longicornia Malaynna. 355 



is bounded on each side by a longitudinal curved ridge, with its 

 concavity outwards. The sublinear antennae also are probably a 

 good although somewhat difficult character to seize. Mr. New- 

 man notices none of these points, the only strongly contrasted 

 peculiarity being the long parallel elytra of this and the broad 

 elytra o^ Jstatlies. The new species described below differs, ??j/er 

 alia, from the type (^E.Jlava) in the posterior third of the elytra 

 being black, and the abdomen and legs fulvous. 



Eustathes semiusta. 



E. fulva, vel rubro-fulva, antennis elytrisque postice nigris. 



Hnh. — Amboyna. 



Fulvous or reddish-fulvous, finely pubescent, the posterior third 

 or a little more of the elytra, black ; head with a slight semicir- 

 cular or rather horse-shoe-shaped raised line between the eyes, 

 the convexity downwards, the front obscurely punctured ; pro- 

 thorax impunctate, the ridges glabrous, black and shining; scutel- 

 lum semicircular ; elytra finely and irregularly punctured, the 

 longitudinal lines only slightly elevated ; body beneath and legs 

 fulvous, the outer edges of the intermediate tibiae, in one speci- 

 men, bordered with black hairs ; antennae black, a little shorter 

 than the body in the male. 



Length 6 lines (,^), 8 lines ( ? ). 



Cyanastus. 



Caput et oculi ut in Astathe. Antennce corpore breviores, basi 



valde distantes ; scapo articulo tertio longiore ; secundo paulo 



elongato ; quarto et sequentibus gradatim decrescentibus. 



Prolhorax baud callosus, lateribus tumidus, basi bisinuatus. 



Elytra convexa, ampla, baud carinata, postice latiora, apice 



rotundata. /'erfes mediocres ; <i6i<» subsequales. Prosternum 



demissum, angustatum. Mesosternum angustatum, declive, 



metasterno baud occultum. Metasternum valde convexum. 



Corpus amplum. 



The habit of this genus is very similar to that o^ Astathes, but 



the body is in no respect depressed. In its technical characters, 



however, it is more nearly allied to Chreonnma, differing principally 



in its longer and more cylindrical scape, the bisinuate base of the 



prothorax, and very convex outline. I'he two species described 



below agree in coloration, but the prothorax of the second is dif-
