The frmns Orphinus o{ iMi)tsi.liul>ky, quite wrongly placed 

 with Orphihis in Dallu Tone's Catalogue, is really a large 

 and impoitaiit one, of which a nilinher of species have heen 

 described under the name of Cri/ptorrhopitlum, while many 

 more remain undescrihed. Keitter has stated that the typical 

 species, O. haviorrhoiililh, Motsch., helonf^s to Cryptor- 

 rhopulitm, jind has changed its name to C. mutachulskiji ; but 

 in 11)08 (Bull. S ic. Eiit. Egy pte, i. p. 45) ho do.scril)ed a 

 so-c.illed ne\v genus {^'E(/irio.ita) , the characters of which are 

 precisely those of Oifih'mus. He placed in it only a single 

 8peci«'S (jjlobulirornis) from Egypt, and omitted to note that 

 many others, including several pieviousiy described by him- 

 s<lt, are congeneric with it. As already siate<l by Sharp 

 (Biol. Centr.-Amer., Coleopt. ii. 1, p. l>52), Cryplunhopalum 

 IS really a well-inarked American genus, and the various 

 Oriental and Austialiaii insects which have been referred to 

 it have none of them its essential feature, viz , an antennal 

 club composed of two large, nearly equal joints. Tiie chief 

 diagnostic character of Orphinus, as given by Motschulsky, 

 is a "club composed of two very unequal joints, the last 

 circular." The statement that the aiitenna is y-jointed is 

 probably due to Mut-clnd>ky wrongly counting the minute 

 joints preceding the club, as the number is eleven in the 

 species known to me. The last joint is flat and circular, 

 very large in the male, with the preceding joint relatively 

 small and connate with it. In the lemale the penultimate 

 joint is larger and tiie last smaller. In some, if not all, 

 of the species the la.-t ventral segment is broadly depressed in 

 the male and the hind margin |)roduced into a sharp spine on 

 each side of the depression, 'i'he mesosternum is broad and 

 completely divided by a channel, which receives the sjiinoso 

 prosternal process. 



Sharp and Blackburn did not know the genus Orphinus, or 

 t!iey wouKl certainly have placed in it the Old-World insects 

 they have provisionally called Cryptorrhopalum. Until 

 other genera are created, it will probably be most natural to 

 transfer to it all the non-American insects now unnaturally 

 associated wiih Crgptorrhopalum. The following may be 

 regarded as typical species of Orphinus: — O. h(vmorrhoidaUs
