EPIPHRAGMA, 193 



and longipes Lw. are likewise LimnopMlse. The genus Tanymera 

 Lw. contains T. gracilicornis, which belongs to the relationship of 

 the North American Limnophila recondita 0. S. Tanysphyra 

 Lw. and Critoneura Lw. seem likewise to be Limnophilae. The 

 amber genus Trichoneura Lw. is distinguished by the first longi- 

 tudinal vein being incurved towards the second, and ending in it, 

 almost as in the Cylindrotomina. I take it to be a Limnophila 

 with four posterior cells ; what appears to be the end of 'the first 

 vein, is in reality the marginal cross-vein, whereas the real end of 

 this vein, touching the costa, is visible, but feebly marked ; this 

 structure reminds of a similar one, often occurring among the 

 Limnohina (compare Tab. I, fig. 2, the wing of Dicranomyia 

 pubipenjiis), but not observed among the Limnophilina. The 

 shortness of the auxiliary vein in TricJioyieura, the course of the 

 central cross-veins, the position of the great cross-vein, etc., re- 

 mind of the wing of Limnophila quady^ata (Tab. II, fig. 9), and 

 convince me that Trichonem-a is related to it. 



Gen. XXVII. EPIPHRAGMA. 



Two submarginal cells ; five posterior cells ; discal cell closed ; sub- 

 costal cross- vein at the tip of the auxiliary vein; a supernumerary cross- 

 vein between the costa and the auxiliary vein. Wings glabrous, handsomely 

 pictured. Eyes glabrous. Antennse 16-jointed ; two basal joints of the 

 llagellum incrassated, almost coalescent. Tibiae with spurs at the tip; 

 empodia distinct ; ungues smooth. 



The antennffi, bent backwards, do not reach beyond the basis 

 of the wings ; basal joint elongated cylindrical, second joint short, 

 cyathiform ; third joint elongated, incrassated ; a suture a little 

 beyond its middle indicates that it consists of two almost coales- 

 cent joints ; the following joints are elongated, slender, with 

 rather long verticils. Collare moderately developed ; thoracic 

 suture deep. Feet rather strong ; the Spurs at the tip of the 

 tibiae comparatively long and distinct. The wings (Tab. II, fig. 

 8, wing of E. solatrix) are broad and handsomely pictured in all 

 the known species. The venation is nearly the same in the three 

 species which I have before me : there is a strong supernumerary 

 cross-vein between the auxiliary vein and the costa ; the origin 

 of the praefurca is very strongly arcuated, often with a stump of 

 a vein ; the petiole of the first submarginal cell is longer than 

 the great cross-vein in E. picta and fascipennis ; shorter than the 

 13 Sept., 1888.
