In his classification of the Melolonthidae ('Genera des 

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

 that an Indian insect, Dejeania alsiosia, 131., was the sole 

 known non-American representative of tbe great Sub-tribe 

 Macrodactylides. In the Ann. & Mag. for 1907 (ser. 7, 

 vol. xix. p. 436), I announced that Dichelomorpha ochracea, 

 placed by Burmeister in the Hoplides, was really congeneric 

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

 occupied must be replaced by Dichelomorpha. I also referred 

 to this genus a species (D. marginata, Nonfr.) wrongly 

 described as a Hoplia. The number of described species 

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

 generally misplaced, so that the utmost confusion still 

 prevails amongst them. 



Dichelomorpha ochracea, described by Burmeister in 1855, 

 was again described by Boheman in 1858 as a species of 

 Dichelus {chinensis, Boh.), and in 1900 Fairmaire 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
