A SYNOPSIS OF THE AMERICAN SPECIES OF 

 SCOLIONEURINAE. 



By Alex. D. MacGillivray. 



The European species of this subfamily were originally 

 referred to the genus Blennocampa. Konow in 1886 removed one 

 of the species from Blennocampa under the generic name of 

 Entodecta and in 1890 the remaining species under the name of 

 Scolioneura. These genera, he has associated with Blennocampa 

 and its allies under the tribal name of Blennocampides^ in his last 

 analysis of the group. The first American species was described 

 by Norton in 1867 as Selandria capitalis, later, 1895, referred to 

 Scolioneura by Marlatt- and two new species described. S. A. 

 Forbes^ in 1885 described Mctallus ruhi from two male specimens 

 bred from larvae mining in the leaves of cultivated blackberries. 

 This species was referred to the genus Fenusa by Cresson^ in 

 1887 ^s a possible variety of Feniisa curia Nort. Konow in the 

 Genera Insectorum, evidently on the authority of Cresson, makes 

 Metallus a synonym of Fenusa and adopts ruhi as a good species. 

 An examination of Forbes's type proves it to belong to the Scol- 

 ioneurinae. Since Metallus antedates both Entodecta and Scolio- 

 neura, if it should be found later that only two generic names 

 •can be retained in this subfamily, Metallus will have to be 

 used for one of them. A fifth species was added by Kincaid'' in 

 1900 from Alaska under the name of Femisa alaskana, a species of 

 Entodecta. Finally a sixth species was described by Konow'', 

 Entodecta htimilis, from Alaska in 1908. The present writer in 

 1906^ separated Scolioneura and Entodecta from the Blennocam- 

 pides as a distinct subfamily, based on the divergent condition
