This small subfamily comprises a number of genera, all evidently of tropical 

 origin, and all parasites of the rhynchotous family Coccidx. 



The first genus to be described was Eitnotus Walker, in 1834. It was later 

 named Trityphus by Ratzeburg, and again rechristened Megapelte by Forster. 



In 1863 Motschulsky described, briefly, poorly, and sometimes inaccuratel}'-, 

 several new genera from Ceylon, which belong here, and proposed for the group the 

 name Muscidides, stating that " lis se distinguent des Fteromalides 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 I'abdomen, 

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

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

 comme chez les Fteromalides." 



The genus Eiinotus Walker, was described twenty years before Muscidea Mot- 

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

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

 the term 3Iuscidides not being tenable. 



Cephaleta Motschulsky, if I have identified it correctly, belongs here, but Mot- 

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

 description and the poor figure, I think is a Eulophid, and probably identical with 

 Pentacladia Westwood, described in 1835.

2. Scutellum large, but not extending beyond the base of the abdomen 3 



Scutellum abnormally large, extending over most of the abdomen. 



Head very wide, lenticular, wider than the thorax ; antennte 8 or 9-jointed, the flagellum cla- 

 vate Scutellista Motschulsky (type S. cyanea Motsch.).

whole surface of the abdomen 5
