1878. ElCHHOFF, W.(ii). 



The description of materiarius Fitch given by Eichhoff in his 

 Ratio Tomicinorum is by far the most correct although it was 

 published 50 years ago. Therefore it seems to be necessary to 

 quote it here : 



Linearis, cylindricus, nigro-piceus, subopacus, parce pilosellus, thorace 

 elongate, anterius subtiliter rugoso-exasperato, posterius laevi, elytris basi 

 dilutioribus, vix conspicue seriatim aciculato-punctulatis, apice rotundato, 

 integro. Long. 3-3.2 mm. 



Staturem fere et habitum coleopterorum ex genere Ptcrocyclon (Corthyltts 

 fasciatns Er.) exhibens, sed antennis aliter constructis. Caput deflexum, 

 nigrum, subnitidum, fronte depressa, parce subtiliter punctata, linea media 

 subelevata, laevi ; pilis parcis, longioribus, adspersa, in margine antico non 

 ciliato, ore inde denudato. Oculi oblongi, antice sinuati. Antennae feru- 

 gineo-testaceae, capitulo suborbiculari, compresso, subinfuscato, nitido, 

 utraque pagina suturis duabus arcuatis notato, articulis subeaqualibus. Pro- 

 thorax latitudine amplius, dimidio longior, cylindricus, basi truncatus, 

 lateribus rectis, parallelis, apice obtuse rotundatus, angulis posticis (desuper 

 intuenti) acute rectis; supra valde cylindrice convexus, piceus, dorso ante 

 medium lineola transversa, elevata, notatus, anterius dilutior, subrufescens, 

 rugis imbricatis subtiliter exasperatus, tenuissime pubescens, posterior 

 glaber, subnitidus, laevis, imo vero oculo arcute armato, omnium subtilis- 

 sime parce punctulatus. Scutellum piceum, sat magnum, triangulare, nitidum 

 laeve. Elytra cylindrica, latitudine thoraxis et illo fere tertia parte longiora, 

 basi truncata, humeris vix elevatis subrotundatis, lateribus rectis, a basi ad 

 medium et ultra, post medium ad apicem fortiter rotundata ; supra cylindrice 

 convexa, nigro-picea vel brunneo-testacea, basi dilutiora, subnitida, versus 

 apicem pilis paucis, seriatis adspersa, laevia, imo vero subtilissime lineato- 

 punctato, interstitiis latissimis, transversim subtilissime aciculata strigulata, 

 absque stria suturali ; declivitas apicalis convexe rotundata, declivis, in 

 singulo elytro tuberculo obsolete, parum elevato, a sutura remote, notata ; 

 marge apicalis communiter obtuse rotundatus. Corpus subtus nigre- 

 piceum, cerebre subtiliter punctulatum, glabrum. Pedes ferrugineo-testacei, 

 tibiis angustis, parum cempressis, antrorsum vix dilatatis, tarsis testaceis.
