 label '^Hemerobius tolimensis," Irazii, Costa Rica (Schild-Burgdolf 

 collection) ; 1 9, Chico, Cundinamarca, Colombia, 2800 m., Jan. 24, 

 1959 (J. F. G. Clarke); 1 9, Barranquilla, Colombia, Mar. 20, 1952, 

 labeled by Parfin as near Hemerobius tibialis Navas or H. tolimensis 

 Banks (J. H. Hughes) ; 1 9, Valle Medellin, Colombia, September 1945

 This species is close to Hemerobius pacijicus Banks, from which 

 it can be distinguished by the somewhat narrower forewing with an 

 "almost acute" apex. The male genitalia are also very much like 

 those of pacijicus, differing conspicuously by the presence of a rather 

 large spiny process slightly anterior to apex of the upper arm of the 

 bifurcate anal plate. This process is directed inward and only 

 shghtly upward so that often it is not seen in a lateral view of the 

 anal plate. The shape of the anal plate is otherwise like that in 

 pacijicus. The processes of the aedeagus are also of the same type. 

 The dilated part of each paramere is produced into a long, curved 

 projection.

 variegated with dark brown on sides. Legs pale. Abdomen brownish. 



Forewing 6.5 mm. in length, elongate oval, apex rounded; membrane 

 hyaline with very distinct markings : two brown fasciae over gradates, 

 one over outer gradates intersected by a broad brown zone occupying 

 space between first and second branches of radial sector external to 

 inner gradates and extending to wing margin. Some distinct macula- 

 tions in apical and hindmarginal areas; a very dark spot over each 

 of following: crossvein m-cu, first fork of M, first fork of Cui, and over 

 the cubital crossvein. Venation sparsely spotted with brown. Three 

 branches to radius; basal crossvein between R and M at very origin
