Mr. T. V. Wollaston on the Coleoptera of St. Helena. 23 



was found in St. Helena by Mr. Melliss, this would seem to be 

 the smallest of the true Notioxeni hitherto brought to light ; 

 and Avhilst it agrees with the last species in its somewhat 

 brassj-green hue, it recedes from it totally in its unpunctured, 

 alutaceous, and less shining surface, and from all the others 

 here enumerated in its elytra (which are a good deal shortened 

 behind) being free from strise, with the exception of a single 

 deep one (evanescent anteriorly) on each alongside the suture.. 



(Subfam. HOMCEODERIDES. 

 Prothorax simplex, sc. linea transversa nulla instruetns.) 



Genus 37. Homceodera (nov. gen.). 



Corpus et instrumenta cibaria fere ut in Notioxeno, sed antennce 

 aperte remotius ab oculis insertae, prothorax simplex (iiec linea 

 basah instructus), atque articuhis primus tarsoruni posticorum minus 

 elongatus. 



Ab ofioios, siinilis, et fie/j'/i thorax. 



The ^imd facie aspect of the three species described below 

 is so much that of the smaller Notioxeni (the N. dimidiatus 

 and alutaceus) that I had at first imagined them actually to 

 belong to the same genus ; but a more careful inspection will 

 show that they have certain peculiarities which, although in- 

 significant perhaps in other families, are of primary import- 

 ance amongst the Anthrihidce.^ and which necessitate the es- 

 tablishment of a special group for their reception. Thus, they 

 have no appearance whatsoever of a transverse line either be- 

 fore or at the extreme base of their ]jrothorax (a structure of 

 peculiar significance in the Anthribids) ; their antennae also 

 are implanted distinctly further from the eyes than is the case 

 in Notioxenus (where the scrobs absolutely adjoins the anterior 

 margin) ; and the first joint of their two hinder feet is less 

 elongated. In their more or less faintly metallic, sparingly 

 pubescent, and sculptured surfaces they have much the ap- 

 pearance of minute Notioxeni.
