CORDULECERUS INQUINATUS. "205 



Cordulecerus inquinatus^ Gerst. 

 [M. T. Voipoiuui. lü, p. 89 (1888)]. 



Among a collection of Ascalaphidae from Chauchamayo, 

 Peru, I found a cf specimen of a Cordulecerus (now in my 

 collection) which I longtimes regarded to be new, but now 

 I refer it with certainty to inquinatus Gerst, 



It differs from Gerstacker's description in the following 

 character. The wings are wholly dark smoky brown, so 

 that the very small pterostigma is difficultly to be found. 

 Gerstacker writes that his types have wholly hyaline wings, 

 not at all tinted and this would be a good prima facie 

 character to distinguish it from the related vulpecula-^xon^. 

 My specimen is quite mature and has flown longtimes. We 

 may believe that Gerstacker's type-specimens were young or 

 immature ones and that inquinatus like the related vulpecula 

 Brm. etc. also gets brown wings by higher degree of maturity 



Ulula praecellens, Gerst. 



[M. T. Vorpomm. 16, p. 3 (1884)]. 



Belongs certainly to the genus Cordulecerus in the neigh- 

 bourhood of surinamensis F. and suhiratus Wlk., the club of 

 the antennae being spoonshaped and ochraceous, whereas in 

 the genus Ulula it is pyriform and dark coloured. Also the 

 abdominal segments are partly ochraceous and black as in 

 Cordulecerus. Such colours are unknown to me in Ulula. The 

 anal angle of the hind wings is obtuse-angular so that the 

 transition from anal border in hind border is to be seen. 

 In true C/^^w/a- species, with the exception of arnp/a M. Lachl., 

 the hind border is gradually rounded off. 



Gerstacker's type is a $, my specimen also; the male is 

 unknown and when discovered the question will be surely 

 explained. 



My specimen is from Lita (Ecuador). 1 got it by means 

 of purchase from the London naturalist Rosenberg.
