species (vide Ritsema's « Remarks » in Notes from tJie Lei/den 

 Museum, vol. III, 1881, p. 10); more recently Mr. Waterhouse 

 has described M. Forbesn {Annals and Magazine of Nat. Hist. , 

 1881), bui I am quite unable to separate this species from M. 

 Saundersii Pascoe. — Mr. Waterhouse (who seems not to have 

 compared Pascoe's type-specimens , as he says : « Near Saundersii , 

 but judging from the figure it is a more robust species ») des- 

 cribes it as differing chiefly in having « the base of the elytra and 

 all the humeral region thickly studded with shining granules » ; 

 the granules of Saundersii are described by Mi'. Pascoe as follows : 

 ((the elytra with numerous granules at the side near the shoulder 

 and a few at the base ». — Secondly Forlesii should differ in 

 having c( each elytron with three patches of white pubescence , the 

 first and second placed as in M.^ Saundersii but very irregular in 

 form, the third very elongate and as if formed of the two apical 

 spots of M. Saundersii » ; this character however is of no value at 

 all as proved by my male specimen, of which consequently the right 

 half should belong to Forhesii and the left half to Saundersii. — Of 

 course the only difference that remains, and still doubtfully, are 

 the somewhat more numerous basal granules of M. Forhesii, a 

 very poor character indeed for separating two specimens from the 

 same locality '), in a group of which the species in many respects 

 are so much subject of variation. — In the figure of 31. Saundersii 

 the basal granules are indeed reduced to a minimum , but that 

 figure is not very exact; who should suppose , judging from it , that 

 the insect is (( pube subtillissima cinerea indutus » '? 



Mr. Pascoe, establishing -the genus J/éV7öctv'o<^?6'a, placed it between 

 Baiocera and Ap'iona ^); Mr. Lacordaire in his Genera des Colé- 

 opth-es , and the authors of the Munich Catalogue placed it after 

 Apriona; two new genera have been established since, Vu: Alato- 



1) Mr. Ritsema kindly did me observe that although Mr. Pascoe mentions 

 Megacriudes Saundersii from Sumatra only, that species is figured in Mr. A. R. 

 Wallace's Malay Archipelago ., vol. I pi. 3 fig. ö, among remarkable beetles found 

 at Simunjou , Borneo. 



2) In his tabulation of the genera of the Lamiinae it is placed after Apriona.
