antennis prothorace vix longioribns, articnUs duobus basalibus 

 validis, secundo dimidio breviore ; prothorace paulo longiore quani 

 latiore, lateribu.s rotuadatis ; elytris postice paulo gradatim lati- 

 oribus. Long. 2| lin. 



Hah. Christchurch. 



Eleale opiloides. 



E. elongata, ceneo-fusca, fulvo-varia, vage breviter pilosa; antennis 

 modice elongatis, clara laxe articulata ; capita prothoraceque con- 

 fertim piinctatis, hoc capite angustiore, basi angusto, in medio 

 fulvo ; scutello cordiforrai ; elytris fortiter punctatis, apicem versus 

 paulo gradatim latioribus, faseiis duabus apiceque fulvis notatis ; 

 pedibus fulvis. Long. 2^ liu. 



Hah. Christchurch, Auckland. 



Not unlike a small individual of Opilus mollis. The genus 

 is somewhat doubtful. 



ECTOMIDA. 



Characteres generici fere ut in Prhtodero, sed tarsia tibiisque aliis, 

 seil. articulis duobus basalibus conjunetis triangulum breviuscu- 

 lum formantibus, tertio parvo, angusto ; tibiis extus compressis, 

 margine exteriore denticulatLs. 



Dermestes scaher^ Fab.*, is congeneric with Pristoderus ant- 

 arcticus^ White ; Erichson's Ulonotus is probablj founded on 

 one of these two (he does not describe any species) ; Lacor- 

 daire, indeed, suggested the identity of these genera. In 

 Pristoderus the tarsi are simply linear, and the tibia? filiform, 

 not denticulate externally. The species here described is re- 

 markable on account of the dilatation, deeply divided into 

 lobes, of the sides of the prothorax ; the insect varies in colour 

 from uniform yellowish testaceous to brownish or with brown- 

 ish patches. 



Ectomida lacerata. 



E. oblonga, depressa, subtestacea, aliquando infuscata vel fusco 

 variegata, subtiliter tomentosa ; capite tuberculis parvis instructo ; 

 antennis articulis duobus basalibus crassis, tertio ad octavum grada- 

 datim brevioribus, clava fusca, articulis duobus basalibtis valde 



* "Kova HoUandia " is given as the habitat ; but the type in the British 

 Museum is the only individual I have seen. Dermedes limbafus, Fab. 

 (Ent. Syst. i. p. 234) is either my Phycosecis discoidea or P. atomaria (ante, 

 vol. xvi. pp. 21.3, 214). I incline to the former ; but Mr. C. O. Waterhouse, 

 who has carefully compared th^^m, think.s it is the latter ; the two speci- 

 mens in the British Museum are barely recognizable. Fabricius must 

 have been labouring under difficulties when, in describing the.se two 

 sppcics from the Bauksian collection, he referred them to Derrnestes, with 

 which, it i.s ahno.^t ncfdless to say, thpv have no affmitv.
