This small subfamily comprises a numl)er of" genera, all evidently of tropical 

 origin, and all parasites of the rhynchotous fiimiiy Coccidir. 



The first genus to be described was Ennotns Walker, in 1834. It was latei- 

 named Tritijphus by Ratzeburg, and again rechristened Mccjapdte by Forster. 



In 1863 Motschulsky described, briefly, poorly, and sometimes inaccurately, 

 several new genera from ( 'ejdon, wliicli lielong here, and proposed for the group the 

 name Musddides, stating that " lis se distinguent des Pteromalides par leur forme 

 plus raccourcie et plus large, qui rappelle celle des Chalcidides et par leur mesono- 

 tum, qui prend quelquefois une telle extensione, qu'il recouvre tout ral)domen, 

 comme ches les Scutellaires parmi Hemipteres, ce qui ftxit replier les ailes horison- 

 talement sous ce mesonotum d'une maniere analogue. Les ailes sont pubescent 

 comme chez les Pteromalides.'' 



The genus Eunotns Walker, was described twenty years Ijefore Muscidea Mot- 

 schulsky, and I prefer to call the group EunotinR', after the first described genus, 

 in accordance with the rules of zoological nomenclature, rather than the Mascideimv, 

 the term Musddides not being tenable. 



Cephaleta Motschulsky, if I have identified it correctly, belongs here, l)ut Mot- 

 schulsky correlated with it a male insect with branched antennae, which, from the 

 descrijition and the poor figure, I think is a Eulophid, and probalily identical with 

 Pfj?i<acZacZiu Westwood, described in 1835.
