Abstract T、、onewspeciesoftheanthribidgenusMecoce,・Illaaredescribedfrom
SouthVietnamandNorthThailandunderthenamesofM、l,ata,labeo1-utn(fromS.Viet-
nam)andMa,1goo,lao(fromN.Thailand).
Thegenus Mecoce1・InaJORDAN(1895, p. 164)belonging to the tribeAcorynini
comprisestwelvespeciesofanthribidbeetlesdistributedinSoutheastAsiaandNew
Guinea.Theseanthribidscanberecognizedatfirstsightonhavingverylongantennae
inthemalelikeCedusofthesametribe.The femaleantennaeofthegenusareshort,
andhavethegeneralcharacteristicsofthetribeAcorynini.
Recently, acollectionof Vietnameseanthribidswassubmitted tome for taxo-
nomicstudythroughthecourtesyofMr.M.NIsHIMuRAofTokyo.Inthiscollection,I
foundastrangespeciesof Mecocerinacollectedbyhimself in Lam DongProvince,
SouthVietnam.Anadditional strangespeciesof thegenuswascollected inChiang
MalProvince,whenIvisitedThailand for thefirsttime. Afteracarefulexamination, it
becameapparentthatbothhadnotbeendescribedbefore.Theywillbenamedinthe
presentpaper.
Before going further, I wish to express my sincere gratitude to Professor Y.
WATANABEoftheLaboratoryofEntomology,TokyoUniversityofAgriculture,Profes-
sor K.MoRIMoTooftheEntomologicalLaboratory,KyushuUniversity,andDr.S.-I.
UENooftheNationalScienceMuseum(Nat.Hist),Tokyo, fortheirconstantguidance
