 and monotypy.

 America (ser. 5) [v. 5] : 21, 216. 



type-species : Dactylopius sacchari Cockerell, 1893, by original designation 

 and monotypy. 



The author established this genus for a distinctive grass-infesting pseudococcid 

 having many characters in common with Trionymus Berg. Williams, 1962: 50, 

 described a second species in the genus.

type-species: Hemioerlesia ceardi Balachowsky, 1928, by original designa- 

 tion and monotypy. 



The author placed this genus in the Aspidiotini, Aspidiotina, related to 

 Murataspis Balachowsky.

type- species : (Saissetia coffeae Deplanche, 1859) =Lecanium coffeae 

 Walker, 1852, by monotypy. 



The descriptive material associated with the publication of this name covered 

 a mealybug and possibly the coccid currently recognized in this country as 

 Saissetia hemisphaerica (Targioni-Tozzetti). The association of the name Sais- 

 setia with a group of leeanine coccids having aereolated dorsal derm at maturity, 

 along with other common characteristics, is so thoroughly established in ento- 

 mological literature, especially in the economic field, that we believe it would 

 be a great mistake to even consider reorientation of the application of the name 

 because of confusion that exists in the original description. 



The correct name to be applied to the type-species has also been uncertain. 

 There is no great assurance that Deplanche examined specimens of the insect 

 that is widely known today as S. hemisphaerica Targioni-Tozzetti, 1867, since 

 there are apparently no recent records of the occurrence of this insect in Tahiti. 

 However, coccid workers have more or less arbitrarily accepted the fact that 

 coffeae Deplanche^ coffeae Walker, is the same insect as hemisphaerica. Cocke- 

 rell, 1894j : 71-72, suggested this identity and Laing, 1927 : 39, reverted to the 

 use of coffeae Walker in place of hemisphaerica. Williams, 1957: 314, examined 

 Walker's original material, confirmed its identity with the species known as 

 hemisphaerica and concluded that Saissetia coffeae (Walker) should now be 

 used in place of Saissetia hemisphaerica (Targioni-Tozzetti).

The author assigned this genus to "Diaspididae with 'two-barred' ducts. Non- 

 pupillarial."
