ICHNEUMON-FLIES — GELINAE I MESOSTENINI 397 



reared lots from Grapholitha molesta, from various localities, by various 

 workers. 



We find the species in thickets and in and at the edges of moist 

 deciduous Vv'oods, most of them on or flying among foliage at one 

 to two meters height. The males have a fast, weaving flight, like the 

 male of Cryptanura banchiformis , and seldom alight. Females are 

 slower and are more often seen resting on foliage. 



This species occurs in the Carolinian, Austroriparian, and Tropical 

 faunas. It parasitizes a great variety of small cocoons and cases. 



3. Lymeon leiponeuron, new species 



Figures 333,f,g 



Front wing of male 3.7 to 4.1 nun. long, of female 3.5 to 4.0 mm. 

 long; clypeus convex, not prolonged into a conical point; lateral lobe 

 of mesoscutum polished, with very sparse, small, weak punctiu-es; 

 discoidella completely absent; thyridiiun of second tergite transverse. 



Head, body, and hind coxa marked with ferruginous, white, and 

 black as in figure 333, f (cf ) and 333,g (9) ; palpi of male white, of female 

 fulvous; scape fulvous, the rest of antenna brown, darker in male, with- 

 out a white band; legs fulvoferruginous, the front and middle coxae of 

 both sexes and the front and middle trochanters of male, white, the 

 front and middle coxae of female with some fulvous areas; front and 

 middle tarsi of male browmish apically; hind tibia of male somewhat 

 darkened; hind tarsus of male f uscof erruginous ; wings faintly infus- 

 cate, a little more strongly infuscate in female. 



This species appears to be an endemic of southern Florida. It is 

 related to Lymeon fuscipenne (Brulle) and L. subfiavescens (Cresson), 

 both of the West Indies. These two have been in the separate genus 

 Christolimorpha because of an abbreviated (or absent) discoidella. 

 The species leiponeuron lacks this vein entirely. The shortening or 

 loss of the discoidella helps to distinguish these three as a group of 

 related species, but their other characters are very similar to those of 

 the genotype of Lymeon, so it seems best to merge Christolimorpha 

 with Lymeon. Hemiteles fuscipennis Brulle 1846 and LI. subfiavescens 

 Cresson 1865 are hereby referred to Lymeon' (new combinations).
