REVISION OF GENUS FURNARICOLA — CARRIKER 421 



Furnaricola pipraphaga, new species 



Figures 15a, 28 



Holotype female adult, from Pipra pipra comata Berlepsch and 

 Stolzman, collected by the author at Enefias, Chanchamayo, Peru, 

 March 12, 1930 (Carriker type no. 801). 



Diagnosis: Head decidedly triangular, somewhat similar to that of 

 F. triangularis, but the mandibles are quite different, as well as the 

 preantennary carinae, clavi and gular plate (see fig. 28). Head also 

 resembles that of pyriglena in shape, but the abdominal sclerites are 

 very different, the tergites in pyriglena almost filling the segments 

 and with prominent sternites in III- VII, while in the present species 

 the pleurites are without heads and tergites widely separated by 

 hyaline bands, and the sternites, if present, are entirely invisible, 

 excepting the genital sternite covering portions of VII and VIII. 



One long and five short setae behind the short, slender lateral spines. 

 Male unknown. Represented by the holotype female only. 



Measiu-ements follow next species. 



Furnaricola inexpectata, new species 



Figures 14a, 29 



Holotype female adult, from Pipra caeruleicapilla Tschudi, col- 

 lected by the author at La Pampa, southeast Peru, July 8, 1931 

 (Carriker type no. 802). 



Diagnosis : Head very differently shaped from that of F. piprajihaga 

 described above, being somewhat similar to that of F. acuticeps choco- 

 ana, but with more rounded temples and much wider frons and with 

 wide, heavily pigmented preantennary carinae having corrugated 

 inner margins. The gular plate very similar to that of pipraphaga, 

 but pterothorax longer and wider and \Ndth third pair of legs much 

 smaller. Also lacks the sternites as in pipraphaga; long spines on 

 VIII similar, but only three very short setae back of them. 



Measurements of the types of F. pipraphaga and F. inexpectata are 

 as follows: 



Note: There is a faint possibility of straggling in the case of this and the pre- 

 ceding species, although no real proof. The genus Furnaricola is, on the whole, 

 quite sedentary in its habits, clinging tightly to the feathers of the dead bird, 

 and not moving about as do many other genera. The only thing that is suspicious
