MEGALESTES(?) ANGLICUS, new species. 

 Plate 61, fig. 9. 



Part of basal half of wing preserved, colorless, with dark veins; 

 origin of median sector to origin of nodal sector about 7 mm. ; width 

 (depth) of wing at level of origin of nodal sector about 5 mm. ; vena- 

 tion, so far as visible, essentially as in the Indian genus Megalestes,^ 

 differing, however, in the much greater length of the cell in fork at 

 origin of median sector, this cell being about as long as the ones 

 immediately apicad of it. The cells between the nodus and origin of 

 nodal sector are more numerous than in Ortholestes, and agree very 

 exactly with the condition in Megalestes major Selys. The zigzag 

 lower sector of triangle is also unhke Ortholestes, but agrees with 

 Megalestes. The condition at the base of the subnodal sector is 

 unlike that of Lestes or Ortholestes, but agrees with Megalestes, except 

 for the fact that the distance from the origin of the sector to the first 

 crossvein is about as long as the crossvein.
