205 Tenebrionidae und Curculionidae. 4 07 
Long. 25 mm. Lat. 13V2 mm. 
A very close ally of M. nitida Haag-Rut. The shape is nearly the same but the elytra are more 
ampliated, and instead of being quite smooth are covered with very small granules separated by an interval 
about equal to three times their own diameter -

Genus Psammodes. 
57. Psammodes tuberculifer Haag-Rut. 
Niger, valde elongato-ovatus, nitidus, antennae pedesque rufo-brunnei, illae graciles, hi brevissime 
pubescentes; caput vix punctulatum ; prothorax longitudine nonnihil latior, lateribus in medio perparum 
ampliatis, supra convexus, fere gibbosus, tenuiter crebreque aciculatus, margine basali tenui in medio 
obliterata; scutellum lateraliter granulis sparsis nonnullis obsitum ; elytra elongato-ovata, ad medium parum 
ampliata latitudine tertio longiora, in disco vix longitudinaliter arcuata, postice abrupte dehiscentia apice 
ipso deplanato in processu subporrecto producto, utroque seriebus 8 vel 9 e tuberculis compressis acutis 
retro spinosis lateraliter posticeque instructis, seriebus laterum basim fere posticis partem post mediam disci 
attingentibus ; abdomen crebre aciculatus; pectus punctato-granosum, breviter fulvo- pubescens. S Segm. 
abdom. I — 3 dense ferrugineo-tomentosa. 
Long. 28 mm. Lat. I3V 2 mm. 
This species is allied to P schultzei, of which it has the elongated form, it differs by the shape of 
the tubercles which, instead of being vertically erect and rounded at the tip, are slightly conical, strongly 
slanting backwards and compressed laterally very much in the manner of those of its close ally P. pierreti 
Am. The other two allies, P tuber culipennis and P mashunus, have, like P. pierreti,. the elytra much more 
ampliated in the centre.

58. Psammodes gibberosulus n. sp. 
Niger, supra subopacus , antennae graciles, prothoracis basim attingentes, rufo-brunneae ; caput 
epistomaque crebre granulata, genis antice acute angulatis ; prothorax longitudine tertio latior, lateraliter 
modice rotundato-ampliatus angulis posticis rotundatis, antice gibberosus, utrinque leviter declivis, postice 
nonnihil deplanatus, ad angulos posticos utrinque leviter impressus, basi subsinuata, tuberculis minutis acutis 
retrorsum ductis fereque confluentibus obtectus ; scutellum granulosum; elytra prothorace basi tertio latiora 
humeris rotundatis, deinde valde ampliato-ovata, parte postica sensim dehiscente margine laterali posticaque 
deplanatis, haud costulata, granulis acutis crebre obtecta; pedes breves, validi, scabrosi, femoribus posticis 
apicem segmenti abdominis antepaenultimi attingentibus; abdomen aciculatum, pectus punctatum granosumque. 
Long. 18 — 23 mm. Lat. 10—14 mm - 
This species which belongs to the group of P. scrobicollis Fahr, is closely related to P myrmidon 
P£r. which occurs in the Prieska district of the Cape Colony. It differs however from the latter by the 
closely granulated head, and the anterior part of the thorax which is more or less plainly gibberose 
in the centre of the anterior part, and also by the more closely set granulated tubercles; on the elytra 
the granules which are separated by a wider Space than their own diameter in both species, are slightly 
finer in P gibberosulus. 
This species seems to ränge from Port Nolloth to Walfish Bay, in the sand dunes of the coast. 
Hab. Namib near the Prince of Wales Bay (south of Angra Pequena), May 1903.
