Lnnyicornia Malayana. 315 



pile, more or less speckled with fulvous, ochreous or greyish ; 

 prothorax much shorter than the elytra, striped in the middle or 

 not; elytra oblong, neither narrow nor trigonate, finely punctured 

 except at the base, the punctures becoming nearly obsolete to- 

 wards the apex ; body beneath with a thin whitish or greyish 

 pubescence, occasionally tinged with fulvous. 



Length 6 — 10 lines. 



Possibly several species are here united, but I must con- 

 fess that I am unable to separate them by any characters that 

 can be relied upon as permanent. I cannot distinguish M. 

 Thomson's Gnotna sticticollis, Arch. Ent. i. 297, by his descrip- 

 tion, from this or either of the two preceding species.

Mecotagus, Pascoe, Proc. Zool. Soc. 1866, p. 252. 



Caput exsertum, antice breve, clypeo apice lato ; tuberibus 



antenniferis validis, basi approximatis. Ocuii mediocres, 



lobo superiore magnitudinis normalis. Antennce elongatae ; 



scapo obconico, prothoracem vix attingente, apice cicatricoso ; 



articulo tertio scapo triplo vel quadr\iplo longiore ; quarto 



tertio dimidio breviore ; cseteris aequalibus, ultimo longiore 



(^) excepto. Prothorax elongatus, sub-cylindricus, la- 



teribus hand vel vix antice incurvatis. Elytra breviuscula, 



ovata, apicibus emarginatis. Pedes elongati, antici lon- 



giores ; femora linearia ; tibice anticae sub-arcuatae, apice 



inermes ; tarsi articulo basali sub-elongato. Prosternum 



simplex. Mesosternum elevatum, productum. 



Cerambyx tigrinus, Oliv., is the type of this genus, a congener 



of which has been erroneously referred by Mr. White to Pelargo- 



derus, Serv. It is allied to Gnotna, from which it differs in the 



form of the prothorax, the linear femora, the longer basal joint of 



tlie tarsi, and other characters. I'lie species referred to by Mr. 



White under the name of *'P. tessellatus, Guer.," does not appear 



to be described ; the following has a very distinct style of pubescence 



from the (two ?} species previously known.
