In liis classification of the ]\Icl(jlontliidie (Hienera (1(8 

 Coleopteres/ vol. iii.) Lacordaive noted as a remarkable fact 

 that an Indian insect, Dejeania alsio!>ia, Bl., was tlie sole 

 known non-American representative of the great Sub-tribe 

 Macrodactylides*. In the Ann. & JNIa^. for 1907 (ser. 7, 

 vol. xix. p. 436), I announced that Dichelomo'pha ochracea, 

 placed by Burmeister in the Hoplides, was really congeneric 

 Avith Dejeania, and that the latter name having been pre- 

 occupied must be replaced by Diclielumorpha. 1 also referred 

 to this genns a s[)ecies {D. maryinatu, Nonfr.) wrongly 

 described as a Hoplia. The number of described species 

 allied to these is now fairly considerable, but ihey have been 

 generally misplaced, so that the utmost confusion still 

 pi'cvails amongst them. 



DidieluniorpJia ochracea, described by Burmeister in 1855, 

 was again described by Bohcn)an in 1858 as a species of 

 Dichelus {chinensis, Boh.), and in 1900 E<iirmaire transferred 

 it under that name to yet another genus, which he named 

 Sinochelus, adding two more species, which also belong to 

 Dichelomorpha. In 1881 Sharp described a species from
