Furnaricola myrmeciza, new species 



Figures 12a, 25, 26 



Holotype female and allotype male adults, from Myrmeciza i. 

 immaculata (Lafresnaye), collected by the author at Hcda. Santana, 

 Santander, Colombia, Oct. 10, 1949 (Carriker type no. 799). 



Diagnosis: May be recognized by the shape of the head, the entire 

 lateral margins from base of temples to frons uniformly convex (see 

 fig. 25), and with the hyaline band around frons wide. Heads of 

 pleurites slender, pointed, and curved inward. The holotype has 

 three long spines on right side of segment VIII and the usual two on 

 left side. Have seen one other case of three spines on right side of 

 VIII. 



Male genitalia very characteristic, there being presently no other 

 known species quite like it. The basal plate is small, expanded at 

 anterior end; paramera nearly as long as basal plate, slender, tapering, 

 with a reverse curve, and with a slender bifurcation at sides of endo- 

 mera; endomera tjrpical. 



Represented by the female holotype, male allotype and one male 

 and one female paratypes, and by a single female from Myrmeciza 

 laemosticta pallida, collected at Hcda. Belen, Antioquia, which can- 

 not be separated from the female holotype. Measurements follow 

 next species. 



Furnaricola pyriglena, new species 



Figures 13a, 27 



Holotype female adult, from Pyriglena leuconota picea Cabanis, 

 collected by the author at Enenas, Chanchamayo, Peru, March 4, 

 1930 (Carriker type no. 800). 



Diagnosis: A rather large species with a conical-shaped head, 

 narrow frons and rounded temples. There are no outstanding 

 characters for this species, excepting shape of head, anterior and 

 gular plates and shape of segment VIII of abdomen. Legs small, 

 especially the coxae and second leg; median portion of pleurites black. 



Measm-ements of the types of F. myrmeciza and F. pyriglena are 

 as follows:
