genus have been more thoroughly compared one with 

 another, it may be possible greatly to shorten specitic 

 descriptions. 



Stress has been laid on tlie iinportanoc of the form cf the 

 abdominal segments. It may be added that in this respect 

 the ? 9 often furnisli far more distinctive charac ters than 

 the (^ ^ . But, beyond an examination of the form of the 

 J claspers, no study has yet been made of tlie genital 

 apparatus in either sex. Such a study mi;^ht coiisideruldy 

 modify present views on the species, and might prove that 

 the ^ (^ , which sometimes appear almost inseparable, really 

 possess distinguishing characters as good as tliose of the ? ? . 



I. — Xtcteribiidm fro.m Ceylon and India. 



The material dealt with here consists almost entirely of a 

 collection made by ]\lr. J. C. F. Fryer in Ceylon iii 1911 

 and 1912. I have, however, included two species, examples 

 of which were recently collected in India by ]Mr. T. Bain- 

 briggc Fletcher: one of these, Cyclopodia roylei (Westw.), 

 is also contained in Fryer^s Ceylonese collection ; the other, 

 FenicilUdia fletcheri, is the only form here described as a 

 new species, and it is represented among the Ceylonese 

 material by a varietal form also described as new under the 

 name Penwillidia fletcheri, war. pumila. 



Thesubjoined list (p. 212) enumerates the species discussed, 

 sliowiug also their distribution and hosts so far as these are 

 at present known. With the exception of no. 2, the type- 

 form of FenicilUdia fletcheri, all are now known irom 

 Ceylon ; and as, to the best of my knowledge, no other 

 sjjecies has been recorded therefrom, the li>t includes the 

 Avhole Nyctcribiid fauna of that island as known up to the 

 ])resent time. The seven forms new to Ceylon are marked 

 with an asterisk. ^Moreover, PeniciUidia jenynsi was pre- 

 viously only doubtfully recorded from that island, the only 

 sure record for which appears to have been that of Cyclu- 

 podia sykesi. 



Besides the description of the new species and new 

 variety, previous descriptions of certain other species are 

 amplitied and modiMed, and some forms not hitherto illus- 

 trated are figured. Thus, Nijcteribia {Acrocho/idiu) euxesta 

 (Speiser) is removed from the genus PeniciUidia ; the abdo- 

 men is i'uUy described, and figures are published for the 

 first time. Cyclopodia ferrarii has not previously been 

 figured, and earlier deseiiptions of it are amplified. Cyclo- 

 podia roylfi, formerlv placed in Nyctcribia^ is fnllv described
