566 Mr. Francis P. Pascoe's Notes on 



Genus Macrones. 

 1. Macrones capita. 



M. fulvo-rufus ; antennis nigris, apicem versus sensim pallidi- 

 oribus ; elytrorum carinis basi excepto, femoribus posticis 

 basi, tibiisque medio, nigro-chalybeatis. 



Port Curtis. 



Fulvous-red, on the protlioras approaching to a golden orange ; 

 head coarsely punctured, rather broad, with the sides parallel 

 below the eyes ; antennae black, but becoming gradually paler 

 from the fifth or sixth joint; lip very small ; eyes nearly round, 

 black ; prothorax roughly punctured, rather longer than broad 

 with a strongly marked, quadrate gibbosity in the middle, and a 

 strong tubercle on each side ; scutellum triangular ; elytra rather 

 broader than the prothorax at the base, where they are fulvous- 

 red, gradually tapering to the apex, each with four rugose carinas, 

 which, except at the base, are steel black, the intervals being nearly 

 white ; first abdominal segment elongate, slender, pale green, the 

 rest and sterna ferruginous-red ; legs very slender, tibiae of the 

 intermediate and posterior pair, except at their extremities, and 

 basal half of the post-femora, black ; posterior pair of tarsi white. 



Length 11 lines. 



Of the five species o^ Macrones, this approaches the most nearly 

 to Macrones rufus, W. W. Saund., but differs in the colour of the 

 antennae and elytra, and the black intermediate and posterior 

 tibiae. Amongst the genera that may be grouped around Steno- 

 derus, Macrones and Enckoptera are at once distinguished by their 

 elytra diverging at the suture, their prolonged muzzle, and entire, 

 rounded, or only slightly ovate, eyes. 



Of these genera, however, Etichoptera differs from Macrones 

 chiefly in its more slender proportions, narrower tarsi, and in the 

 basal joint of the anterior pair being linear and not triangular. 

 Brachopsis comes very near those genera, but it has no muzzle. 

 Psilomorpha is another ally, distinguished by the normal suture 

 of the elytra, and differing from Stenoderus chiefly in the elongate 

 basal joint of the tarsi. Oroderes again, notwithstanding its reni- 

 form eyes, cannot be placed very far from these genera ; and, 

 much as they differ in habit among themselves, I am not disposed 

 to separate very widely Stephanops, Diotima, Eroschema, Tessa- 

 romma, Bardistus, Tricheops, Uracanthus, &c., and even Bimia 

 (through Ak'iptera and Tropis). Many of these genera have 

 elongate, often conical anterior coxae, with the cotyloid cavity 

 forming, with few exceptions, a very large angle externally.
