The species is allied to A. naJma, Sss., from Mexico, but 

 differs in coloration. 



Anaplecta fusca, n. sp. (Plate XVI, fig. 4.) 



9 . Minute ; fusco-castaneous. Head piceous ; pronotum ellip- 

 tical, entirely dark castaneous-brown. Tegmina castaneous, with 

 ten highly irregular costal veins connected with each other by 

 transverse venulte, discoidal field with two longitudinal veins, 

 reticulated. Wings dark fuscous, five costal veins, radial vein with 

 a humeral and a discoidal branch, median vein approximated to the 

 radial vein and the very narrow medio-discal field crossed by two 

 transverse venulse, an oblique transverse venula runs from the apex 

 of the ulnar vein to the median vein and from this two short 

 obliquely longitudinal venuhe are given off, first axillary vein 

 quadri-ramose. Apical area more than two-fifths of total wing- 

 length, basal margin straight. Cerci golden-yellow, supra-anal 

 lamina rounded. 



Total length 4 mm. ; length of tegmina 3'5 mm. 



Cachabi, Ecuador ( W. F. H. Bosenherg coll., Dec. 1896). 

 One example (Oxford Museum). 



The venation of the tegmina and wings in this species is 

 highly characteristic, and unlike that of any other known 

 species. 



Anaplecta varijjennis, n. sp. (Plate XVI, figs. 5, 6.) 



$. Closely allied to A. parvipennis, Sss. and Zhnt., but differs in 

 the following particulars : — the lateral borders of the pronotum and 

 the mediastinal field of the tegmina are opaque white not hyaline, 

 the clypeus is testaceous, the discoidal field of the tegmina is 

 reticulated, the medio-discal field of the wings is crossed by two 

 transverse venulse, the sub-genital lamina is deeply cleft and has 

 almost a valvular appearance. The tegmina vary in length from 

 4-8 mm. to 4 mm., the wings from 6 mm. to 3 mm., in the latter 

 case the most notable reduction is that of the apical area which 

 ranges in size from two-fifths of the total wing-length to one-sixth. 



Total length 6-2 mm. 



Paramba, Ecuador, 3500 feet {W. F. H. Rosenberg 

 coll., May 1897). Five examples (Oxford Museum). 



In spite of the variation in size of the wings, their 

 venation remains practically unaltered ; as already noted, 

 the most marked range of size is shown by the apical area
