No. 2326. THREE TRIBES OF ICHNEUMONINAE—CUSHMAN. 



Genus LYCORINA Holmgren. 



Lycorina Holmgren, Ofvers. Vet.-Akad. Forli., vol. 16, 1859, p. 126. Genotype.— 

 Ly carina triangulifera Holmgren. 



This genus is unknown in the North American fauna, the genotype 

 and only described species being European. 



Distinct by the characters employed in the ke.y, in most of its other 

 features it is very similar to the other genera of the tribe. 

 CHLOROLYCORINA, new genus. 



In structure this genus stands between Lycorina Holmgren and 

 Toxophoroides Cresson. In the perpendicular posterior face of the 

 propodeum it is allied to Ltjcorina while differing from that genus in 

 lacking all the carinae except the obsolete apical and traces of the 

 median. In color pattern, which in this group is undoubtedly of 

 generic value it is allied to Toxophoroides. From both genera the red 

 color of the pleura distinguishes it. 



Genotype. — {Glypta ?) Toxophoroides scitula (Cresson). 



The species are readily distinguished by the color characters em- 

 ployed in the following key. 



KEY TO SPECIES. 



1. Hind- tibiae with alternating bands of white and black, tarsi white at base; 



mesoscutum more or less red; triangular areas of tergites each with a white 



spot scitxda (Cresson). 



Hind tibiae white only basally, reddish in the middle, tarsi entirely black; 

 mesoscutimi without red; triangular areas of tergites immaculate 2. 



2. Hind coxae red; ovipositor distinctly longer than hind tibiae. 



albomarginata (Cresson) . 

 Hind coxae black with apex white; ovipositor and hind tibiae equal in length. 



soror Cushman.

Discussion based on type and two specimens compared with 

 type by the present writer. 



This species has been adequately described by both Cresson and 

 Walsh. It is very distinct from the other two species of the genus 

 by the characters used in the key. 



The United States National Museum collection contains two 

 females, one from Monticello, Florida, where it was reared October 

 7, 1914, by A. I. Fabis under Quaintance No. 10561 from Tetra- 

 lopha subcanalis Walker; and the other reared June 10, 1885, 

 under Bureau of Entomology No. 3722. A note by the late Theo.
