Tieic Species o/Histeridas. 227 



laleribus puuctatis ; elytris violaceis vel purpureis, striis dorsalibus 

 1 et 4 parum abbreviatis, 2-3 suturalique integris ; prosterno 

 bistriafco ; mesosfcerno marginato, stria transversa nulla ; tibiis 

 anticis 4-dentatis. 

 L. 2| mill. 



Oval, convex, body and legs blue-black; head cyaneous ; 

 thorax and elytra rich dark violet, changing to purple in 

 certain lights ; the head moderately excavated, striate over 

 the eyes only, punctuation much scattered ; the thorax with 

 a distinct impression behind the anterior angle, stria com- 

 plete, punctate on the lateral border, with finer points ex- 

 tending towards the disk and gradually becoming less dense, 

 scutellar puncture minute ; the elytra, striae, outer humeral 

 wanting, inner very short, basal, but clear, 1 shortened well 

 before the apex, 2-3 complete and almost joining apically, 4 

 a little longer than the first, 5 wanting, sutural complete and 

 parallel to the suture, apical border sparsely punctured ; the 

 propygidium is clearly but sparsely punctured, the punctures 

 are chiefly at the base ; the pygidium is very minutely punc- 

 tured and the points are more evenly scattered ; the pro- 

 sternum is rather wide, keel impunctate, anterior lobe with a 

 few scattered punctures, bistriate, strise diverging at either 

 end, but widening out most anteriorly ; the mesosternum, 

 marginal stria rather fine, posterior suture visible, but there 

 is no transverse stria ; the first abdominal segment has a 

 conspicuous bent stria on either side ; the tarsi are dull 

 brown and the anterior tibiaj are 4- dentate, the two central 

 teeth are widest apart. 



Most of the brightly coloured species of this genus are not 

 convex ; but this and P. varicolor^ Mars., are the two excep- 

 tions known at present.

Phelister feslivus.

By an oversight I omitted in my description to refer to 

 the tibiaj of this species. The anterior tibias are 3-dentate, 

 the two nearest to the tarsi are somewhat close together, the 

 third is further apart ; this form of the tibia and the some- 

 what curved tarsal grooves show that it belongs to the 

 genus Phelister. 



Phelister chapadce, sp. n. 



Orbicularis, convexiusculus, niger, nitidus, supra punctulatus ; an- 

 tennis pedibusque rufis ; fronte impressa stria late interrupta ;
