Distinguished from the other Indian species by the longer pronotum.

After comparison of the male specimen found near Bombay with a 

 Oeylonese male specimen of Sorni (given by Mr. Green to Dr. Luther as 

 being M. tmiguttatus, Thunb.) I find that it differs only in having the 

 yellow apical margin of the last dorsal segment extremely narrow while 

 it in the typical Ceylonese form is broad, occupying the apical third of 

 the segment. I quite agree with Breddin that M. uniguttatus, as previ- 

 ously understood, consists of several perfectly distinct species. What the 

 true uniguttatus is, can only be decided by a thorough re-examina'tion and 

 minute redescription of the type. There can be little doubt that M. 

 hengalensis, Dall. and assimilis, Dall. (the latter not mentioned in Distant's 

 Indian Fauna) are good species. The difficulties in the study of this 

 genus are increased by the circumstance that the pronotum in many 

 (not all) species is of different structure in the two sexes, being narrower 

 with much longer anterior lobe in the male. 



N.B. — Metochus Scott, which corresponds to Stal's divisional oi Uieuches, 

 is certainly entitled to generic rank. The head is much broader than the 

 apex of the pronotum, and the pronotal lateral margins are narrowly 

 carinated and strongly sinuated, whereas in Dieuclies the head is not or 

 scarcely broader than the apex of the pronotum, and the pronotal lateral 

 margins broadly laminately expanded and not or sarcely sinuated. Owing 

 to this differences \hQ fades of the two genera is quite different, and there 

 are no species forming a transition between them. The differences between 

 Metochus and Dieuches are in fact much greater than between Dieuches 

 and Beosus. The name of the genus was correctly spelt by Scott ; it was 

 wrongly written Methocus by Lethierry and Severing and Metoous by Dis- 

 tant.
